Description

An embodiment of the present invention relates to a mobile terminal device and a program.

Conventionally, there is a known system known as an electronic receipt, in which a receipt or invoice given to a customer by a store when purchasing a product is electronically sent to the customer's mobile device, etc.

By digitizing receipt information in this way, for example, a customer can use a mobile device or the like that he or she carries to input information that identifies the mobile device, and then view electronic receipt data on the display unit of the mobile device. The store transmits electronic receipt information to the customer carrying the identified mobile device.

Meanwhile, stores or companies that operate stores provide services that grant benefits, such as points, to customers as part of their efforts to acquire customers. Benefits at stores are granted to point members who are benefit members who have a contract with the store . The benefit member of the store is identified by entering the store's membership ID using a membership medium such as a benefit card issued by the store , and benefits are granted to the identified member. To grant benefits at other stores, membership media issued by the other stores are used. Stores also issue membership media according to the respective services they provide in order to provide services other than benefits.

In this way, conventionally, when a customer receives an electronic receipt, he/she presents a mobile terminal device such as a mobile terminal that identifies the customer, and when a service is provided, he/she presents a membership medium that identifies the member who provides the service. Therefore, the customer needs to carry both the mobile terminal device and the membership medium, which is very cumbersome. Similarly, when different membership media are issued for each of multiple stores, the customer needs to carry multiple membership media, which is cumbersome.

The problem to be solved by the present invention is to enable a customer to be provided with a service of a specific store simply by carrying a mobile terminal device.

A mobile terminal device according to an embodiment includes an electronic receipt ID display means for displaying a code symbol of an electronic receipt ID for identifying the mobile terminal device, a storage unit for storing store identification information for identifying a store and a store member ID for identifying a customer of the store in association with each other, an input means for inputting the store identification information, and a store member ID display means for extracting the store member ID corresponding to the store identification information from the storage unit when the store identification information is input by the input means and displaying the code symbol of the store member ID. Also, the store member ID display means displays the code symbol of the store member ID on a screen on which the code symbol of the electronic receipt ID is displayed.

The program of the embodiment causes a computer to function as a first storage means for storing first customer identification information that identifies a customer, an input means for inputting store identification information that identifies a store, a transmission means for transmitting the input store identification information together with the stored first customer identification information to an information processing device, and a second customer identification information display means for displaying second customer identification information different from the first customer identification information that identifies the customer in response to the store identification information and the store identification information received from the information processing device in response to the transmission of the first customer identification information.

The program of the embodiment causes the computer to function as a second storage means for storing store identification information that identifies a store and second customer identification information that identifies a customer of the store in correspondence with each other, an input means for inputting store identification information that identifies a store, an extraction means for extracting the stored second customer identification information corresponding to the input store identification information, and a second customer identification information display means for displaying the extracted second customer identification information.

Two embodiments will be described below with reference to the drawings. In each embodiment, an electronic receipt management server will be used as the information processing device. A mobile terminal will be used as the mobile terminal device. As an example of receiving a service, the awarding of points to a customer will be described. Note that the present invention is not limited to the embodiments described below.

First Embodiment
Fig. 1 is a diagram showing the overall configuration of an electronic receipt system according to a first embodiment. As shown in Fig. 1, the electronic receipt system includes a POS (Point of Sales) terminal 1 and a store server 2 installed in a store P1 such as a shopping center, an electronic receipt server 3 installed in a headquarters P3, an electronic receipt management server 4 installed in an electronic receipt center P4, and a mobile terminal 7 carried by a customer.

The POS terminal 1 is connected to a network N2 that connects the store P1 and the headquarters P3. Here, the network N2 is, for example, a dedicated line such as the Internet or a VPN (Virtual Private Network).

The POS terminal 1 is a product sales data processing device that processes product sales data at the store P1. The POS terminal 1 generates receipt information, which is transaction print information including transaction details of the product to be settled, and issues a paper receipt by printing the receipt information with the printing unit 13 described below. The POS terminal 1 also generates electronic receipt information by converting the data format of the receipt information in unstructured format into a structured format different from the unstructured format. The electronic receipt information is receipt information in which the receipt information originally printed on receipt paper is converted into a structured format such as the CSV (Comma-Separated Values) format or the J-son format. The electronic receipt information is transmitted to the electronic receipt management server 4 via the electronic receipt server 3 and stored in the electronic receipt management server 4. The electronic receipt information stored in the electronic receipt management server 4 can be transmitted to the mobile terminal 7 and viewed. The mobile terminal 7 displays the electronic receipt information in a format almost identical to the receipt information printed on receipt paper.

The POS terminal 1 then outputs (transmits) the generated electronic receipt information to the electronic receipt server 3 via the network N2. There is no particular limit to the method of transmitting the electronic receipt information, and a general-purpose protocol such as HTTP or HTTPS may be used. There is no particular limit to the number of POS terminals 1 provided in the store P1, and there may be more than one.

The POS terminal 1 calculates points that can be used at the store P1 according to the amount of the product purchased by the customer, and awards them to the customer. The awarded points are sent to the store server 2 connected by a communication line N1 such as a LAN (Local Area Network), and are accumulated in the store server 2.

The store server 2 manages the sales of the entire store P1. The store server 2 is connected to the POS terminal 1 by a communication line N1 provided within the store P1. The store server 2 manages the sales information of the store P1 based on the sales information at the POS terminal 1. The store server 2 collects the sales information of each POS terminal of the store P1 as settlement receipt information. The settlement receipt information is information obtained by aggregating the sales information of sales made by the store P1 during a specified period (e.g., one day). The settlement receipt information is information obtained by aggregating, for example, sales information by department or class in addition to total sales information for a specified period. Also, for example, information obtained by aggregating sales information by payment type. Also, for example, information obtained by aggregating sales information by time period. Also, for example, information obtained by aggregating sales information by various categories.

The store server 2 also manages the customer points sent from the POS terminal 1 for each customer. When points are awarded, the points are accumulated, and when points are used, the points used are deducted. In this way, the store server 2 also functions as a point server. Note that the point server function may be in a server other than the store server, for example, a headquarters server installed in the headquarters.

The electronic receipt server 3 is provided at the headquarters P3 of the company that operates the store P1, and functions as a corporate receipt management server that manages receipt information for each company that operates the store P1.

The electronic receipt server 3 also receives the electronic receipt information sent from the POS terminal 1 via the network N2. The electronic receipt server 3 also sends the received electronic receipt information to the electronic receipt management server 4 via the network N3 that connects the headquarters P3 and the electronic receipt center P4.

Here, the network N3 is, for example, a dedicated line such as the Internet or a VPN. In addition, there is no particular restriction on the method of transmitting the electronic receipt information, and a general-purpose protocol such as HTTP or HTTPS may be used.

The electronic receipt management server 4 is provided in the electronic receipt center P4. The electronic receipt center P4 manages, for example, electronic receipt information and electronic settlement receipt information of each company that manages receipt information in the electronic receipt server 3. The electronic receipt center P4 is a third-party organization other than the headquarters P3 that operates the electronic receipt server 3. The electronic receipt server 3 may also be managed by a third-party organization, etc.

The electronic receipt management server 4 functions as a customer receipt management server that collectively manages electronic receipt information from various companies that operate stores. The electronic receipt management server 4 stores and manages member data, such as the name and member ID, which is the customer code, of each customer (member) who has registered as a member, the electronic receipt ID (hereinafter referred to as "SRID"), which is a unique terminal code for identifying the mobile terminal 7 that transmits the electronic receipt information, and destination information (e.g., email address) of the mobile terminal 7 to which the electronic receipt information is to be transmitted, in a member master stored in a database DB. Note that a member management server that stores and manages member data may be provided separately from the electronic receipt management server 4.

The electronic receipt management server 4 also receives the electronic receipt information transmitted from the electronic receipt server 3 via the network N3, and stores and manages this electronic receipt information in the electronic receipt information section 43a2 of the electronic receipt management area 43a (described later) held in the database DB (see FIG. 6). In more detail, the electronic receipt information includes elements such as the store information of the store transmitting the electronic receipt information and a member ID, in addition to the transaction details of the product (product sales data), and is managed in association with the member data of the corresponding member.

When the electronic receipt management server 4 stores the electronic receipt information in the electronic receipt information section 43a2, the electronic receipt management server 4 identifies the destination (mobile terminal 7) by referring to the destination information associated with the member ID of the electronic receipt information. Then, the electronic receipt management server 4 notifies the destination via the network N5, which will be described later, that there is electronic receipt information to be sent.

When the electronic receipt management server 4 receives an electronic receipt inquiry specifying a member ID from a mobile terminal 7 connected via a network N5 (described later), the electronic receipt management server 4 extracts electronic receipt information corresponding to the member ID from the electronic receipt information unit 43a2 and transmits it to the mobile terminal 7. Note that if additional information is associated with the electronic receipt information, this additional information is also transmitted to the mobile terminal 7 that made the inquiry.

The mobile terminal 7 is a mobile terminal device such as a smartphone, mobile phone, PDA (Personal Digital Assistant), tablet computer, etc., that is carried by a user (customer) of this system. The mobile terminal 7 is equipped with an application such as a web browser for viewing various information provided on the network N5.

The mobile terminal 7 accesses the electronic receipt management server 4 via the network N5 to register as a member of the system. Here, the network N5 is the Internet or any of various public networks.

In this system, the customer's membership registration for receiving electronic receipt information on the mobile terminal 7 is performed, for example, in the following procedure. The customer sends a blank email from the mobile terminal 7 to the electronic receipt management server 4 via the network N5. The electronic receipt management server 4 sends a URL (Uniform Resource Locator) indicating a page for membership registration to the mobile terminal 7 to the received email address. The customer accesses the URL indicating the page for membership registration from the mobile terminal 7 to display an input screen for inputting the items required for membership registration (name, destination information, etc.). After the customer has finished inputting the necessary items, the electronic receipt management server 4 executes the membership registration in the member master. Thereafter, the electronic receipt management server 4 delivers a membership registration completion email including a member ID and password to the mobile terminal 7. This completes the membership registration. After the member registration, a barcode in which the SRID is converted into a code symbol is displayed on the display unit of the mobile terminal 7 that has been logged in and authenticated.

Furthermore, after the payment process (transaction) at the POS terminal 1, the mobile terminal 7 receives a notification from the electronic receipt management server 4 via the network N5 indicating that the electronic receipt information can be sent from the electronic receipt management server 4. When a member operates the mobile terminal 7 to send inquiry information for electronic receipt information to the electronic receipt management server 4 via the network N5, the electronic receipt information of the member is received from the electronic receipt management server 4. Furthermore, the mobile terminal 7 displays the received electronic receipt information.

In an electronic receipt system with such a configuration, electronic receipt information indicating the details of a transaction (payment) generated by processing product sales data at the POS terminal 1 in store P1 is transmitted to the electronic receipt management server 4 via the electronic receipt server 3 and published on the Web. Therefore, a mobile terminal 7 equipped with a Web browser can download the electronic receipt information published on the Web to the mobile terminal 7 and view it on the Web browser by specifying a URL (Uniform Resource Locator). Note that an application for viewing receipt information may be installed on the mobile terminal 7 to view the information.

Next, the hardware configuration of the main devices that make up the electronic receipt system of the first embodiment will be described using Figures 2 to 8.

First, the POS terminal 1 will be described. FIG. 2 is a block diagram showing the configuration of the POS terminal 1. As shown in FIG. 2, the POS terminal 1 has a control unit 11 that performs various calculations and controls each unit of the POS terminal 1. The control unit 11 is a computer made up of a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores various programs and data, a RAM (Random Access Memory) 11a that temporarily stores various programs and also stores various data in a rewritable manner, and an RTC (Real Time Clock) unit that keeps track of the current date and time.

The control unit 11 is connected to the operation unit 12, the printing unit 13, the display unit 14, the code reading unit 15, the communication I/F 16 and the memory unit 17 via the bus 18.

The operation unit 12 has various operation keys that allow the operator to perform operation input. Examples of operation keys include numeric input keys, cursor keys and a selection confirmation key for selecting a specific item, as well as a closing key 121 for executing the settlement process for one transaction and completing the transaction.

The printing unit 13 is composed of a printer device that prints receipts, journals, adjustment receipts, inspection receipts, etc. The printing unit 13 prints information such as product information of the purchased product, payment information associated with the payment process, adjustment information, inspection information, etc., on a long roll of paper that is transported by a thermal head having a heat generating medium, and then cuts the paper to issue receipts, journals, adjustment receipts, inspection receipts, etc.

The display unit 14 is, for example, an LCD display, and displays various information such as the name and price of the product registered for sale, the total amount of a transaction for which payment has been declared, and the amount of change. The display unit 14 displays various information in the process of issuing a settlement receipt, the process of generating and sending electronic settlement receipt information, and the process of issuing an inspection receipt. The display unit 14 is equipped with an operator display 14a that displays various information to the cashier, and a customer display 14b that displays various information to the customer. The display unit 14 may be configured as a touch panel, in which case the touch panel functions as the operation unit 12.

The code reading unit 15 is a scanner device that optically reads code symbols such as barcodes and two-dimensional codes. The code reading unit 15 reads, for example, code symbols attached to products, code symbols displayed on the display unit of the mobile terminal 7, and two-dimensionally coded code symbols displayed near the POS terminal 1. The control unit 11 inputs the information stored in the read code symbols. The code symbols attached to products hold product codes and the like for identifying the products. The code symbols displayed on the mobile terminal 7 hold SRIDs and member IDs and the like for identifying the customer carrying the mobile terminal 7. The SRIDs and member IDs may be magnetically or electrically stored in the mobile terminal 7. In this case, the stored SRIDs and member IDs are read by a dedicated reading device. The control unit 11 inputs the read SRIDs or member IDs. The two-dimensionally coded code symbols hold store codes for identifying the stores.

The control unit 11 is also connected to a communication I/F (interface) 16 via a bus 18, and can be connected to a network N2 via this communication I/F 16.

The control unit 11 is also connected to the memory unit 17 via the bus 18. The memory unit 17 is an auxiliary storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The memory unit 17 stores a control program 17a for executing various POS operations including product sales data processing, settlement processing, and inspection processing. Based on the control program 17a, the control unit 11 executes product sales data processing and processing related to receipt information. The memory unit 17 stores various data files related to product sales data processing, such as product data files that store product data such as the product name, product code, and unit price of each product.

The storage unit 17 also stores an electronic receipt generation program 17b for generating electronic receipt information from receipt information. The control unit 11 drives the electronic receipt generation program 17b to convert receipt information in unstructured format into electronic receipt information in structured format based on conversion rules described in a receipt information schema (not shown). In this way, the control unit 11 generates electronic receipt information from receipt information.

The electronic receipt information generated by the POS terminal 1 includes the member ID, company code (identification code of the company operating the store), store code, POS number of the POS terminal 1, receipt number, product sales data (including date and time data), etc. Therefore, for example, a consumer goods manufacturer can obtain proof information of purchased products unique to that manufacturer from this electronic receipt information under specific conditions (for example, limited to a specific company operating the store, limited to a specific area, limited to a specific time, etc.). In addition, the electronic receipt information generated by the POS terminal 1 includes an SRID that specifies the mobile terminal 7 that transmits the electronic receipt information.

The memory unit 17 also stores a POS number for distinguishing the POS terminal 1 from other POS terminals 1, a company code (an identification code of the company that operates the store), a type of business code, and a store code that is store information for identifying the store P1. Here, the type of business code is a code (classification code) that distinguishes the type of business and the type of the store, such as a convenience store, supermarket, department store, pharmacy, restaurant, or eating and drinking establishment. In addition, in order to make it possible to identify each store operated by the same company, a different store code is assigned to each store. Note that such type of business and the type of business can be changed at the user's discretion. In addition, the company code (an identification code of the company that operates the store) and the type of business code may be registered in the electronic receipt server 3.

Next, a portion of the memory map of the RAM 11a in the control unit 11 of the POS terminal 1 will be described. In FIG. 3, the RAM 11a has an SRID storage unit 11a1, a product information storage unit 11a2, a sales information storage unit 11a3, and a store member ID storage unit 11a4.

The SRID storage unit 11a1 stores the SRID and member ID input from the code reading unit 15. The product information storage unit 11a2 stores product information (product code, product name, unit price, attribute information, etc.) read from a product master (not shown) based on the product code input from the code reading unit 15. The sales information storage unit 11a3 stores sales information, which is cumulative information that accumulates and stores product information and payment information of products for which payment processing has been executed. The sales information storage unit 11a3 stores sales information for a predetermined period until the settlement processing of the POS terminal 1 is executed. The store member ID storage unit 11a4 stores a store member ID that identifies a point card that can be used at store P1.

The store member ID is, for example, an ID attached to a point card that is issued by a store and can only be used at that store. When the store member ID is identified, it is possible to identify the point card issued by that store. In addition, when the store member ID is identified, it is possible to identify the customer who owns the point card. The store member ID is printed on the point card as a code symbol.

In addition, in the embodiment, a barcode in which the store member ID is converted into a code symbol is displayed on the display unit of the mobile terminal 7. Therefore, the member ID is input to the POS terminal 1 by reading the barcode displayed on the mobile terminal 7 carried by the customer with the code reading unit 15. Therefore, the customer can identify the member ID assigned to the point card by simply carrying the mobile terminal 7, without having to carry the point card.

Next, the hardware configuration of the electronic receipt server 3 that functions as a receipt management server for a company will be explained using the block diagram in FIG. 4. In FIG. 4, the electronic receipt server 3 has a control unit 31 that performs various calculations and controls each unit of the electronic receipt server 3. The control unit 31 is a computer that is composed of a CPU, a ROM that stores various programs and data, a RAM that temporarily stores various programs and rewrites various data, an RTC unit that keeps track of the current date and time, etc.

The control unit 31 can be connected to the network N2 and the network N3 via the communication I/F 32 connected to the bus 34. The control unit 31 is also connected to the memory unit 33 via the bus 34.

The memory unit 33 stores electronic receipt information for each company that operates a store in the electronic receipt management area 33a. The electronic receipt information includes a company code (an identification code for the company that operates the store), an industry/business type code, a store code, a shopper's membership ID, the POS number of the POS terminal 1, a receipt number, product sales data, etc. The memory unit 33 also stores a control program 33b for managing the electronic receipt information stored in the electronic receipt management area 33a.

Next, the hardware configuration of the electronic receipt management server 4 that functions as a customer receipt management server will be described using the block diagram in FIG. 5. In FIG. 5, the electronic receipt management server 4 has a control unit 41 that performs various calculations and controls each unit of the electronic receipt management server 4. The control unit 41 is a computer that is composed of a CPU, a ROM that stores various programs and data, a RAM that temporarily stores various programs and rewrites various data, an RTC unit that keeps track of the current date and time, etc.

The control unit 41 can be connected to the network N3 and the network N5 via the communication I/F 42 connected to the bus 44. The control unit 41 is also connected to the memory unit 43 via the bus 44.

The memory unit 43 includes an electronic receipt management area 43a, a control program 43c, and a customer management area 43d. The electronic receipt management area 43a manages the electronic receipt information of various companies that operate stores, received from the electronic receipt server 3, for each member.

The memory unit 43 also stores a control program 43c for controlling the electronic receipt management area 43a, etc. The memory unit 43 also stores a customer management area 43d for managing customers who are carriers of the mobile terminal 7.

Next, the electronic receipt management area 43a will be described with reference to FIG. 6. In FIG. 6, the electronic receipt management area 43a stores electronic receipt information generated in a transaction for each transaction. The electronic receipt management area 43a includes an SRID section 43a1 that stores an SRID, which is a terminal code that identifies the mobile terminal 7 that transmits the electronic receipt, and an electronic receipt information section 43a2. The SRID section 43a1 stores the SRID read by the code reading section 15 of the POS terminal 1. The electronic receipt information section 43a2 stores electronic receipt information, which is an electronic receipt obtained by converting receipt information for one transaction, in correspondence with the SRID for each transaction. In this embodiment, the electronic receipt information includes the SRID stored in the SRID section 43a1 and the electronic receipt information stored in the electronic receipt information section 43a2.

Next, the customer management area 43d will be described with reference to FIG. 7. The customer management area 43d stores a store member ID that identifies a point card issued at each store, corresponding to the SRID that identifies the mobile terminal 7. In FIG. 7, the customer management area 43d has an SRID section 43d1, a member information section 43d2, a store member ID section 43d3 for store A, a store member ID section 43d4 for store B, and a store member ID section 43d5 for store C. In the embodiment, as an example, the store member IDs of three stores, store A, store B, and store C, are managed.

The SRID section 43d1 stores the SRID that identifies the mobile terminal 7 that receives the electronic receipt. The member information section 43d2 stores the store member ID and member information of the member identified by the SRID (such as the member's name, address, telephone number, family structure, preferences, purchase history, and the address of the mobile terminal 7).

The store member ID section 43d3 stores a store member ID for store A that identifies a point card issued at store A and owned by an individual customer identified by the SRID, along with a store code that identifies store A. The store member ID section 43d4 stores a store member ID for store B that identifies a point card issued at store B and owned by an individual customer identified by the SRID, along with a store code that identifies store B. The store member ID section 43d5 stores a store member ID for store C that identifies a point card issued at store C and owned by an individual customer identified by the SRID, along with a store code that identifies store C.

Here, even if the SRID is the same customer, the store member ID for store A, the store member ID for store B, and the store member ID for store C are all different IDs. Also, store A, store B, and store C may be different stores of the same company, or may be stores of different companies.

Next, the hardware configuration of the mobile terminal 7 will be described using the block diagram in FIG. 8. In FIG. 8, the mobile terminal 7 has a control unit 71 that performs overall control of various calculations and each unit of the mobile terminal 7. The control unit 71 is a computer that is composed of a CPU, a ROM that stores various programs and data, a RAM that temporarily stores various programs and also stores various data in a rewritable manner, an RTC unit that keeps track of the current date and time, etc.

The operation unit 72 is connected to the display unit 73 via the bus 76. The operation unit 72 has various operation keys and a pointing device for the operator (customer) to input operations. The display unit 73 is, for example, a liquid crystal display, and displays various information such as electronic receipt information described below. The display unit 73 may be configured as a touch panel, in which case the touch panel functions as the operation unit 72.

The control unit 71 is also connected to a communication I/F 74 via a bus 76, and can be connected to a network N5 via this communication I/F 74.

The control unit 71 is also connected to the storage unit 75 via the bus 76. The storage unit 75 includes a web browser for viewing various information (contents) published on the web, an electronic receipt compatible program 75a for receiving electronic receipt information from the electronic receipt management server 4, an electronic receipt viewing program 75b for viewing the received receipt information, and an SRID storage unit 75c for storing an SRID for identifying the mobile terminal 7 that transmits the electronic receipt information. The SRID stored in the SRID storage unit 75c is displayed as a code symbol on the display unit 73 by logging in and authenticating the mobile terminal 7. The POS terminal 1 uses the code reading unit 15 to read the code symbol displayed on the display unit 73 and inputs the SRID to the POS terminal 1.

In addition to being read as a code symbol, the SRID may be read magnetically or electrically by the POS terminal 1. The SRID may also be read from a device other than the mobile terminal 7, such as a membership card. A customer ID that identifies a customer other than the SRID may also be read. In this case, the SRID stored in the corresponding electronic receipt management server 4 is obtained based on the read customer ID.

The control unit 71 is also connected to the code reading unit 77 via the bus 76. The code reading unit 77 reads two-dimensional codes. A two-dimensional code including a store code that identifies the store is attached near the POS terminal 1 or near the entrance of store P1. The code reading unit 77 of the mobile terminal 7 captures an image of the attached two-dimensional code using a camera function (not shown) and reads the store code included in the two-dimensional code.

In the embodiment, the two-dimensional code is read by the code reader 77 of the mobile terminal 7 to input the store code, but the store code may be input to the mobile terminal 7 in the following manner. 1. Using a known wireless communication technology, the mobile terminal 7 receives a signal including the store code transmitted from the POS terminal 1 or near the entrance of the store, and inputs the store code. The wireless communication technology is preferably a short-distance wireless communication using NFC (Near Field Communication), infrared, Bluetooth (registered trademark), or the like, but may be other wireless communication technology. 2. The mobile terminal 7 equipped with a GPS (Global Positioning System) function specifies the location of the mobile terminal 7, specifies the store from the address information of the store, and extracts the store code of the specified store from the pre-stored store code. 3. A microphone (not shown) of the mobile terminal 7 collects sounds in a specific range transmitted from the POS terminal 1 or near the entrance of the store. The mobile terminal 7 extracts the store code of the store specified by the collected range from the multiple store codes stored in advance.

Next, the control processing executed by each unit in the first embodiment will be described with reference to Figures 9 to 14.

First, the control process executed by the control unit 11 of the POS terminal 1 operating in accordance with the control program 17a and the electronic receipt generation program 17b will be described with reference to the flowchart shown in FIG. 9.

In FIG. 9, the control unit 11 of the POS terminal 1 determines whether the SRID stored in the mobile terminal 7 has been input by the code reading unit 15 (step S11). If it is determined that the SRID has been input (Yes in step S11), the control unit 11 stores the input SRID in the SRID storage unit 11a1 provided in the RAM 11a of the control unit 11 (step S12). The control unit 11 then returns to step S11 and waits.

If it is determined that the SRID has not been entered (No in step S11), the control unit 11 uses the code reading unit 15 to determine whether or not a store member ID has been entered (step S13). If it is determined that the store member ID has been entered (Yes in step S13), the control unit 11 stores the entered store member ID in the store member ID storage unit 11a4 provided in the RAM 11a of the control unit 11 (step S14). The control unit 11 then returns to step S11 and waits.

If it is determined that the input is not a store member ID (No in step S13), the control unit 11 determines whether the code symbol attached to the product has been read by the code reading unit 15 and a product code has been input (step S21). If it is determined that a product code has been input (Yes in step S21), the control unit 11 executes a product registration process based on the product code (step S22). The control unit 11 then returns to step S11 and waits.

The product registration process involves searching the product master (not shown) stored in the memory unit 17 based on the input product code, reading out the product information (product code, product name, unit price, attribute information, etc.) stored in the product master corresponding to the input product code, and storing it in the product information memory unit 11a2 provided in the RAM 11a.

If it is determined that a product code has not been entered (No in step S21), the control unit 11 determines whether the closing key 121 has been operated (step S31). If it is determined that the closing key 121 has been operated (Yes in step S31), the control unit 11 executes a settlement process for the transaction (step S32). The settlement process refers to a process in which the total amount is calculated based on the product information stored in the product information unit, displayed on the display unit 14, and the transaction is completed based on the payment of various payments.

The control unit 11 then determines whether the store member ID is stored in the store member ID storage unit 11a4 (step S33). If it is determined that the store member ID is stored (Yes in step S33), the control unit 11 awards points based on the amount processed for payment in step S32 (step S34). Specifically, the control unit 11 calculates the points to be earned this time from the amount processed for payment and the base amount per point. The control unit 11 then transmits the calculated points to the store server 2, which functions as a point server.

Then, the control unit 11 generates receipt information in an unstructured format to be printed on receipt paper based on the product information related to the transaction (including the product name, price, and payment amount) (step S35). If an SRID is stored in the SRID storage unit 11a1, the SRID is imported and unstructured receipt information is generated in step S35. If a store member ID is not stored in the store member ID storage unit 11a4 (No in step S33), the control unit 11 proceeds to step S35 without executing the point allocation process in step S34.

Next, the control unit 11 determines whether or not to generate electronic receipt information based on the receipt information (step S36). If the generated receipt information includes an SRID, the control unit 11 determines to generate electronic receipt information.

When it is determined that electronic receipt information is to be generated (Yes in step S36), the control unit 11 drives the electronic receipt generation program 17b to generate structured electronic receipt information by converting the unstructured receipt information generated in step S35 (step S37). The generated electronic receipt information includes an SRID, as shown in FIG. 6. The control unit 11 then transmits the generated electronic receipt information including the SRID to the electronic receipt server 3 (step S38).

Next, the control unit 11 erases the SRID stored in the SRID storage unit 11a1 (step S39). Next, the control unit 11 cumulatively stores the product information stored in the product information storage unit 11a2 in the sales information storage unit 11a3 (step S40). Next, the control unit 11 erases the product information stored in the product information storage unit 11a2 (step S41). Then, the control unit 11 ends the process. Note that if it is determined in step S36 that electronic receipt information is not to be generated, the control unit 11 drives the printing unit 13 to issue a paper receipt on which the receipt information is printed on paper (step S42).

Next, the flow of the electronic receipt management process executed by the control unit 31 of the electronic receipt server 3 operating according to the control program 33b will be described with reference to the flowchart shown in FIG. 10.

The control unit 31 of the electronic receipt server 3 judges whether the electronic receipt information transmitted from the POS terminal 1 in step S36 has been received via the communication I/F 32 (step S51). If it is judged that the electronic receipt information has been received (Yes in step S51), it stores the electronic receipt information for each company in the electronic receipt management area 33a of the storage unit 33 (step S52). Then, the control unit 31 transmits the electronic receipt information stored in step S62 to the electronic receipt management server 4 (step S53) and returns to step S51.

Next, the control process executed by the control unit 41 of the electronic receipt management server 4 operating in accordance with the electronic receipt generation program 43b and the control program 43c will be described with reference to the functional block diagram shown in FIG. 11 and the flowchart shown in FIG. 12.

As shown in FIG. 11, the electronic receipt generation program 43b and the control program 43c executed by the electronic receipt management server 4 are modularized to include a receiving means 411, an extracting means 412, and a transmitting means 413. As actual hardware, the CPU of the control unit 41 reads out and executes the control program 43c from the storage unit 43, thereby executing the receiving means 411, the extracting means 412, and the transmitting means 413.

The receiving means 411 has a function of receiving the first customer specific information and store specific information from the mobile terminal device.

The extraction means 412 has the function of searching the memory unit and extracting corresponding second customer identification information based on the received first customer identification information and store identification information.

The transmission means 413 has a function of transmitting the extracted second customer specific information to the mobile terminal device.

Fig. 12 is a flowchart showing the control process of the electronic receipt management server 4. In Fig. 12, the control unit 41 judges whether or not electronic receipt information has been received from the electronic receipt server 3 (step S71). When it is judged that electronic receipt information has been received (Yes in step S71), the control unit 41 stores the received SRID in the SRID unit 43a1 (step S72). Then, the control unit 41 stores the corresponding electronic receipt information in the electronic receipt information unit 43a2 (step S72). Then, the control unit 41 notifies the mobile terminal 7 having the address stored in the electronic receipt information unit 43a2 that electronic receipt information exists (step S73). Then, the control unit 41 returns to step S71 and waits.

If it is determined that the electronic receipt information has not been received from the electronic receipt server 3 (No in step S71), the control unit 41 determines whether or not there has been an inquiry about the electronic receipt information from the mobile terminal 7 (step S81). The inquiry about the electronic receipt information is executed by operating the mobile terminal 7 that has received the notification in step S73 (details will be described later with reference to FIG. 14).

When it is determined that an inquiry about electronic receipt information has been made (Yes in step S81), the control unit 41 extracts the requested electronic receipt information from the electronic receipt management area 43a (step S82). Then, based on the address included in the extracted electronic receipt information, the control unit 41 transmits the electronic receipt information to the mobile terminal 7 identified by the address (step S83). Then, the control unit 41 returns to step S71 and waits.

On the other hand, if it is determined that the inquiry is not for electronic receipt information (No in step S81), the control unit 41 (receiving means 411) determines whether or not the SRID and the store code that identifies the store have been received from the mobile terminal 7 in the process of step S110 described below (step S91). If it is determined that the SRID and the store code have been received (Yes in step S91), the control unit 11 determines whether or not a store member ID corresponding to the received SRID and store code has been stored (step S92). This determination is made by searching the customer management area 43d based on the received SRID and store code, and if the store code identifies store A, it determines whether a store member ID is stored in the store member ID section 43d3 of store A. Also, if the store code identifies store B, it determines whether a store member ID is stored in the store member ID section 43d4 of store B. Also, if the store code identifies store C, it determines whether a store member ID is stored in the store member ID section 43d5 of store C.

If it is determined that the store member ID is stored (Yes in step S92), the control unit 11 (extraction means 412) reads out the corresponding store member ID from the customer management area 43d (step S93). This read-out store member ID is information converted into a code symbol. The control unit 11 (transmission means 413) then transmits the code symbol information of the read-out store member ID to the mobile terminal 7 (step S94). The control unit 11 then returns to step S71 and waits. Note that the conversion of the store member ID into a code symbol may be performed by the electronic receipt management server 4 or the mobile terminal 7.

If it is determined in step S91 that the SRID and store code have not been received (No in step S91), and if it is determined in step S92 that the store member ID corresponding to the received SRID and store code has not been stored (No in step S92), the control unit 11 returns to step S71 and waits.

According to the first embodiment, the electronic receipt management server 4 reads out the store member ID that identifies the point card that can be used at the store (i.e., the store member ID that identifies the customer of the store) based on the received SRID and store information, and transmits it to the mobile terminal 7. The mobile terminal 7 displays a barcode in which the received store member ID is converted into a code symbol on the display unit 73. Therefore, the mobile terminal 7 that receives this store member ID can display the store member ID. In other words, since the mobile terminal 7 displays customer identification information for the store instead of the SRID, the POS terminal 1 that reads this display can award points to the identified customer based on the store member ID.

Next, the flow of the electronic receipt receiving process executed by the control unit 71 of the mobile terminal 7 operating according to the electronic receipt compatible program 75a and the flow of the electronic receipt viewing process executed by the control unit 71 operating according to the electronic receipt viewing program 75b will be described with reference to the functional block diagram shown in FIG. 13 and the flowchart shown in FIG. 14.

As shown in FIG. 13, the electronic receipt compatible program 75a and the electronic receipt viewing program 75b executed by the mobile terminal 7 are modularized to include a first storage unit 711, an input unit 712, a transmission unit 713, a second customer specific information display unit 714, and a first customer specific information display unit 715. As actual hardware, the CPU of the control unit 71 reads out and executes the electronic receipt compatible program 75a and the electronic receipt viewing program 75b from the storage unit 75, thereby executing the first storage unit 711, the input unit 712, the transmission unit 713, the second customer specific information display unit 714, and the first customer specific information display unit 715.

The first storage means 711 has the function of storing first customer identification information that identifies a customer.

The input means 712 has a function for inputting store identification information that identifies a store.

The transmission means 713 has a function of transmitting the input store specific information together with the stored first customer specific information to the information processing device.

The second customer identification information display means 714 has a function of displaying second customer identification information different from the first customer identification information that identifies a customer in response to the store identification information received from the information processing device in response to the transmission of the store identification information and the first customer identification information.

The first customer specific information display means 715 has the function of displaying the first customer specific information.

Next, the flow of the electronic receipt receiving process executed by the control unit 71 of the mobile terminal 7 operating according to the electronic receipt compatible program 75a and the flow of the electronic receipt viewing process executed by the control unit 71 operating according to the electronic receipt viewing program 75b will be described with reference to FIG. 14.

As shown in FIG. 14, the control unit 71 determines whether or not the user has logged in (step S101). The user cannot receive an electronic receipt or display the store member ID until the user has logged in. Therefore, the control unit 71 waits until the user has logged in to receive an electronic receipt or display the store member ID (No in step S101). During this wait, the control unit 71 can execute other processes. If the control unit 71 determines that the user has logged in (Yes in step S101), the control unit 71 (first customer specific information display means 715) displays a barcode that is a code symbol of the SRID stored in the SRID storage unit 75c on the display unit 73 (step S102).

Figure 15 shows an example of a mobile terminal 7 displaying an SRID. In Figure 15, a barcode 78a indicating the SRID is displayed on the display unit 73 of the mobile terminal 7. By having the code reading unit 15 of the POS terminal 1 read this barcode 78a, the POS terminal 1 can read the SRID that identifies the mobile terminal 7.

Next, the control unit 71 judges whether or not a notification has been received from the electronic receipt management server 4 indicating that the electronic receipt information has been received from the electronic receipt server 3 (step S103). If it is judged that the electronic receipt information has been received (Yes in step S103), the control unit 71 displays a notification indicating the reception on the display unit 73 (step S104). This notification is, for example, a message such as "We have received your electronic receipt."

When it is determined that the notification of receipt of electronic receipt information has not been received (No in step S103), the control unit 71 determines whether or not an inquiry for electronic receipt information has been operated (step S105). The operator of the mobile terminal 7 who has seen the notification operates the operation unit 72 to send inquiry information for electronic receipt information. When it is determined that the operation has been performed (Yes in step S105), the control unit 71 sends inquiry information requesting transmission of an electronic receipt to the electronic receipt management server 4 together with the SRID that identifies the mobile terminal 7 stored in the SRID storage unit 75c (step S106). The electronic receipt management server 4 that has received the inquiry executes the processes of steps S81 to S83 in FIG. 12 to send electronic receipt information to the mobile terminal 7.

On the other hand, if it is determined that the operation is not an inquiry operation for electronic receipt information (No in step S105), the control unit 71 determines whether or not electronic receipt information has been received from the electronic receipt management server 4 (step S107). If it is determined that electronic receipt information has been received (Yes in step S107), the control unit 71 displays the received electronic receipt information on the display unit 73 (step S108). Note that if only electronic receipt information has been received, the control unit 71 displays the electronic receipt information.

If it is determined that electronic receipt information has not been received (No in step S107), the control unit 71 (input means 712) then determines whether or not a store code has been input by the mobile terminal 7 by reading a two-dimensional code attached to the POS terminal 1 or near the entrance of store P1 (step S109). If it is determined that a store code has been input (Yes in step S109), the control unit 71 (transmission means 713) transmits the input store code and the SRID stored in the SRID storage unit 75c to the electronic receipt management server 4 (step S110). The electronic receipt management server 4, which has received the store code and SRID, executes steps S91 to S94 and transmits information in which the store member ID has been converted into a code symbol to the mobile terminal 7.

If it is determined that the store code was not input (No in step S109), the control unit 71 determines whether a store member ID converted into a code symbol has been received (step S111). If it is determined that the store member ID has been received (Yes in step S111), the control unit 71 (second customer specific information display means 714) displays a barcode, which is a code symbol of the received store member ID, on the display unit 73 (step S112). In this case, the control unit 71 erases the display of the barcode indicating the SRID displayed in step S102, and instead displays the barcode, which is a code symbol indicating the store member ID.

Figure 16 shows an example of a barcode displayed as a code symbol for a store member ID. In Figure 16, a barcode 78b, which is a code symbol for the store member ID, is displayed on the display unit 73 of the mobile terminal 7. By having the code reading unit 15 of the POS terminal 1 read this barcode 78b, the POS terminal 1 can read the store member ID that identifies the point card for that store owned by the customer carrying the mobile terminal 7. The POS terminal 1 then executes a process of granting the accrued points to the customer identified based on the read store member ID.

If it is determined that the store member ID has not been received (No in step S111), the control unit 71 then determines whether or not a "back button" (not shown) on the mobile terminal 7 has been operated (step S113). If it is determined that the button has been operated (Yes in step S113), the control unit 71 displays a barcode in which the SRID stored in the SRID storage unit 75c has been converted into a code symbol (step S114). If it is determined that the "back button" has not been operated (No in step S113), the control unit 71 returns to step S103 and waits.

In the embodiment, when displaying in step S112, the display of the barcode indicating the SRID is erased and instead a barcode that is a code symbol of the store member ID is displayed, but it is also possible to display both the barcode indicating the SRID and the barcode that is a code symbol indicating the store member ID without erasing the display of the barcode indicating the SRID.

Figure 17 shows an example in which a barcode that is a code symbol indicating the store member ID is added to the barcode that indicates the SRID without erasing the barcode that indicates the SRID. In Figure 17, barcode 78c displayed on display unit 73 has a barcode section 78c1 that indicates the SRID and a barcode 78c2 that indicates the store member ID. Barcode 78c further has a separator section 78c3 (the part indicated by (99)) that indicates the boundary between barcode 78c1 that indicates the SRID and barcode 78c2 that indicates the store member ID.

The POS terminal 1, which reads this barcode, recognizes barcode 78c1 on the left side of separator 78c3 as a barcode containing an SRID, and reads the SRID from that barcode. The POS terminal 1 also recognizes barcode 78c2 on the right side of separator 78c3 as a barcode containing a store member ID, and reads the store member ID from that barcode. By the mobile terminal 7 displaying in this way, the POS terminal 1 can recognize both the SRID and the store member ID from the read barcode.

As described above, according to the first embodiment, when a store code is input, the mobile terminal 7 transmits it together with the stored SRID to the electronic receipt management server 4. Based on the received SRID and store code, the electronic receipt management server 4 reads out the store member ID that identifies the point card that can be used at the store (i.e., the store member ID that identifies the customer of the store) and transmits it to the mobile terminal 7. The mobile terminal 7 displays the received store member ID on the display unit 73. In other words, the mobile terminal 7 displays customer identification information for the store, and the POS terminal 1 that reads this display can award points to the identified customer based on the store member ID.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to Figs. 18 to 20. The second embodiment differs from the first embodiment in the configuration of the mobile terminal 7. The other configurations are the same as those of the first embodiment. Fig. 18 shows the hardware configuration of the mobile terminal 7 of the second embodiment. Note that in the explanation of Fig. 18, only the differences from the mobile terminal shown in Fig. 8 will be explained. The other configurations that will not be explained are the same as those in Fig. 8. In Fig. 18, the mobile terminal 7 has a customer management area 75d. This customer management area 75d has the same configuration as the customer management area 43d in Fig. 5.

Next, the flow of the electronic receipt receiving process executed by the control unit 71 of the mobile terminal 7 operating according to the electronic receipt compatible program 75a and the flow of the electronic receipt viewing process executed by the control unit 71 operating according to the electronic receipt viewing program 75b will be described with reference to the functional block diagram shown in FIG. 19 and the flowchart shown in FIG. 20.

As shown in FIG. 19, the electronic receipt compatible program 75a and the electronic receipt viewing program 75b executed by the mobile terminal 7 are modularized to include a second storage unit 716, an input unit 717, an extraction unit 718, a second customer specific information display unit 719, and a first customer specific information display unit 720. As actual hardware, the CPU of the control unit 71 reads out and executes the electronic receipt compatible program 75a and the electronic receipt viewing program 75b from the storage unit 75, thereby executing the second storage unit 716, the input unit 717, the extraction unit 718, the second customer specific information display unit 719, and the first customer specific information display unit 720.

The second storage means 716 has a function of storing store identification information that identifies a store and second customer identification information that identifies customers of the store in correspondence with each other.

The input means 717 has the function of inputting store identification information that identifies a store.

The extraction means 718 has the function of extracting second customer specific information stored in correspondence with the input store specific information.

The second customer specific information display means 719 has the function of displaying the extracted second customer specific information.

The first customer specific information display means 720 has the function.

Next, the flow of the electronic receipt receiving process executed by the control unit 71 of the mobile terminal 7 operating according to the electronic receipt compatible program 75a and the electronic receipt viewing process executed by the control unit 71 operating according to the electronic receipt viewing program 75b will be described with reference to FIG. 20. Note that in FIG. 20, the description of the same parts as in FIG. 14 will be omitted or simplified.

In FIG. 20, the process of steps S121 to S129 executed by the control unit 71 is the same as the process of steps S101 to S109 in FIG. 14, and therefore the description will be omitted. In step S129, if it is determined that a store code has been input (Yes in step S129), the control unit 71 checks the customer management area 75d and determines whether a corresponding store member ID exists based on the SRID stored in the SRID storage unit 75c and the input store code (step S130). If it is determined that a corresponding store member ID exists (Yes in step S130), the control unit 71 (extraction means 718) extracts the corresponding store member ID from the customer management area 75d (step S131). Then, the control unit 71 (second customer specific information display means 719) displays a barcode, which is a code symbol indicating the read store member ID, on the display unit 73 (step S132).

If it is determined that the store code has not been entered (No in step S129), the control unit 71 executes the processes of steps S133 and S134. However, these processes are the same as the processes of steps S113 and S114 in FIG. 14, and therefore will not be described here.

According to this second embodiment, when a store code is input, the mobile terminal 7 reads out the store member ID based on the stored SRID and displays it on the display unit 73. In other words, the mobile terminal 7 displays customer identification information for the store instead of the SRID, and the POS terminal 1 that reads this display can award points to the identified customer based on the store member ID.

In addition, according to the second embodiment, the mobile terminal 7 extracts and displays the store member ID by itself without inquiring about the store member ID from the electronic receipt management server 4. Therefore, even if some kind of failure occurs in the network N5 between the mobile terminal 7 and the electronic receipt management server 4, the store member ID can be extracted and displayed without any problems.

Although an embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the gist of the invention. This embodiment and its variations are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.

For example, in the above embodiment, a point card was used as an example of a membership medium issued by a store, but the type of card can be any type as long as it is issued by a store.

The programs executed by the electronic receipt management server 4 and mobile terminal 7 in the embodiment are provided in the form of installable or executable files recorded on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disk (DVD).

The programs executed by the electronic receipt management server 4 and the mobile terminal 7 of the embodiment may be stored on a computer connected to a network such as the Internet and provided by downloading them via the network. The programs executed by the electronic receipt management server 4 and the mobile terminal 7 of the embodiment may be provided or distributed via a network such as the Internet.

The programs executed by the electronic receipt management server 4 and the mobile terminal 7 of the embodiment may be configured to be provided by being pre-installed in a ROM or the like.
