Description

The present invention relates to a sales system, a mobile terminal, a server, and a sales method, and more particularly to a technology for making product sales more efficient at event venues, etc.

As an example of a sales format that uses IC cards to sell products, a product sales system has been proposed in which only product samples are displayed on the sales floor and the products purchased are stored in a back yard or the like, in which a membership card (non-contact IC card) that stores a membership ID is read by an electronic shelf tag (ID reader) and a purchase reservation for that product is made (Patent Document 1). This product sales system not only simplifies the product reservation operation for customers, but also automatically updates the stock quantity when the purchase reservation quantity is updated, making inventory management easier and improving sales efficiency.

Meanwhile, at event venues for sporting events, concerts, etc., a service is provided that sells merchandise, photographs, and other products on the day of the match or event. This sales format at the venue can result in queues, and sometimes the products cannot be purchased because they are sold out, but because buyers are highly motivated to buy and it also becomes a place for fans who have gathered at the venue to interact with each other, the venue sales themselves tend to be popular as an event. Another advantage is that you can see the actual product before purchasing.

However, in current venue sales, products such as photographs, posters, and key chains are displayed or exhibited on product catalog signage, walls, shelves, etc., and customers browse these products while filling out a designated order form or verbally telling the counter staff which products they want. At the counter, the staff checks the order forms and verbally confirms them, gathers the products placed in the back room, calculates the amount, and performs the accounting. These tasks are often done manually by staff, which not only takes time, but is also prone to errors in quantities and prices. Therefore, there is a demand for a more efficient sales format at venues.

The present invention was made in consideration of the above problems, and aims to provide a sales system etc. that can improve the efficiency of product sales at event venues etc.

A first invention for solving the above-mentioned problem is a sales system in which a server and a cash register terminal are connected to each other via a network, the system comprising: a mobile terminal including a storage means for storing a user ID issued when an application is installed on the mobile terminal and product information previously stored in the mobile terminal ; a display means for displaying product images; a selection means for accepting a selection of a product to be purchased from the product images displayed on the display means; and a transmission means for transmitting identification information of the product selected by the selection means to a server together with the user ID stored in the storage means, the server receiving the product identification information and the user ID transmitted from the mobile terminal. a storage means for storing a user ID as purchase intention information, a payment information generating means for generating payment information for each user, and a payment information transmitting means for transmitting the payment information to a cash register terminal, wherein the cash register terminal is equipped with a user ID reading means for reading only the user ID displayed on the display means of the mobile terminal for receiving payment information, a payment information acquiring means for transmitting the user ID read by the user ID reading means to the server and acquiring the payment information corresponding to the user ID from the server, and a payment processing means for performing payment processing based on the payment information acquired by the payment information acquiring means.

According to the sales system of the first invention, a user ID that is automatically issued when an application is installed on a mobile terminal and product information are stored in advance in the mobile terminal , and when a product to be purchased is selected from the product image displayed on the mobile terminal, identification information of the selected product is transmitted to a server together with the user ID. The server stores the product identification information and user ID transmitted from the mobile terminal as purchase information, generates payment information for each user, and transmits the payment information to a cash register terminal. The cash register terminal reads only the user ID for receiving the payment information , obtains the payment information corresponding to the read user ID from the server, and performs payment processing. As a result, the information of the product selected by the purchaser on the mobile terminal is managed by the server for each user, so that the purchaser does not need to take notes of the product he or she wants or verbally tell the cashier staff, and can make payment by waving an IC card, which makes the purchase of the product smooth. In addition, by reading only the automatically generated user ID, it is possible to easily obtain the payment information corresponding to the user ID from the server. Furthermore, there is no need to inquire about product information from the server.

In the first invention, it is preferable that the cash register terminal further comprises a payment completion information sending means for sending payment completion information to the server when the payment process for the product is completed, and the server further comprises a payment completion information receiving means for reflecting the payment completion information in the purchase intention information stored in the storage means when the server receives the payment completion information from the cash register terminal. This makes it possible to manage the payment status in the sales system.

In the first invention, the mobile terminal is provided with a purchase plan information acquisition means for acquiring from the server the purchase plan information corresponding to the user ID stored in the storage means, a display means for displaying the purchase plan information acquired from the server, a correction means for inputting corrections to the displayed purchase plan information, and a correction information transmission means for transmitting the corrected purchase plan information to the server, and it is preferable that the server updates the purchase plan information stored in the storage means based on the corrected purchase plan information transmitted from the mobile terminal. This makes it possible to correct the purchase plan information transmitted to the server by the mobile terminal.

In the first aspect, it is preferable that the user ID displayed on the display means of the mobile terminal is a QR code (registered trademark).

This optically reads a QR code or the like corresponding to the user ID, making it easy to reliably read the user ID of the terminal of the user waiting in line and reliably prevent erroneous recognition of the turn. In addition, there is no need to implement hardware and software for wireless user ID reading, and there is no need to prepare unnecessary protocols.

Furthermore, in the first invention, the cash register terminal is equipped with a purchase plan information acquisition means for acquiring the purchase plan information corresponding to a user ID corresponding to the payment information from the server, a display means for displaying the purchase plan information acquired from the server, a correction means for correcting and inputting the number of items in the displayed purchase plan information, and a correction information transmission means for transmitting the corrected purchase plan information to the server, and it is preferable that the server updates the purchase plan information stored in the storage means based on the corrected purchase plan information transmitted from the cash register terminal.

This allows the user to easily change the purchase intention information at the cash register terminal before purchase, and also allows the user to easily adjust the number of items in the purchase intention information at the cash register terminal, thereby dramatically improving user convenience.

In the first aspect, it is preferable that the purchase candidate information displayed on the display means includes a plurality of product images.

This allows the user to easily and simultaneously graphically check multiple items of purchase information on his/her own terminal (and the cash register terminal), making it possible to modify multiple items at once , dramatically improving user convenience.

According to a second invention, a sales method in a sales system in which a server and a cash register terminal are connected to each other via a network includes the steps of: a mobile terminal having a storage means for storing a user ID issued when an application is installed on the mobile terminal and product information previously stored in the mobile terminal , displaying product images; a step in which the mobile terminal accepts a selection of a product to be purchased from the displayed product images; a step in which the mobile terminal transmits identification information of the selected product together with the user ID stored in the storage means to a server; a step in which the server stores the product identification information and the user ID transmitted from the mobile terminal as purchase intention information; a step in which the server generates payment information for each user; and a step in which the server transmits the payment information to a cash register terminal.
This sales method includes the steps of: the cash register terminal reading only the user ID displayed on the display means of the mobile terminal for receiving payment information; the cash register terminal transmitting the user ID to the server and obtaining the payment information corresponding to the user ID from the server; and the cash register terminal performing payment processing based on the obtained payment information.

According to the second invention, the server manages information on the products selected by the purchaser on the mobile terminal for each user, so the purchaser does not need to take notes on the products he or she wants or verbally tell the cashier, and can make payment by waving his or her IC card, which makes the purchase of products smooth. Also, by reading only the automatically generated user ID, it becomes possible to easily obtain payment information corresponding to the user ID from the server. Furthermore, there is no need to inquire about product information from the server.

The present invention makes it possible to provide a sales system that can increase the efficiency of product sales at event venues, etc.

The following describes in detail a preferred embodiment of the present invention with reference to the drawings.

[First embodiment]
Fig. 1 is a diagram showing a sales system 1 according to a first embodiment of the present invention. In the following description, a goods sale held at an event venue or the like will be described as an example. As shown in Fig. 1, the sales system 1 according to the first embodiment includes an IC card 2 storing a user ID 251, a product panel 3 having user ID reading units 32a, 32b, 32c, ... for reading the user ID 251 stored in the IC card 2, an editing terminal 4, a cash register terminal 5, and a server 6. The product panel 3, the editing terminal 4, and the cash register terminal 5 are communicatively connected to the server 6 via a network 7.

The IC card 2 is a contactless IC card that the purchaser carries when using the sales system 1, and is, for example, an IC card used as a membership card or an admission card, or an IC card distributed at an event venue. The configuration of the IC card 2 will be described with reference to Figures 2 to 4.

2, the IC card 2 includes a non-contact IC chip 21 and an antenna 27. The non-contact IC chip 21 includes a CPU (Central Processing Unit) 22, a ROM (Read Only Memory) 23, and a RAM 24.
The computer 10 is configured with a RAM (Random Access Memory) 23, a RAM (Random Access Memory) 24, an EEPROM (Electrically Erasable Programmable Read Only Memory) 25, and an I/F (Interface) 26, etc.

The CPU 22 loads programs stored in the ROM 23 or EEPROM 25 into a work memory area on the RAM 24 and executes them. The ROM 23 is a read-only memory that permanently stores programs, data, etc. The RAM 24 temporarily stores loaded programs and data, and also provides a work area that the CPU 22 uses to perform various processes.

EEPROM 25 is a non-volatile memory that allows data to be rewritten, and as shown in FIG. 4, has a storage area for storing a user ID 251. User ID 251 is information for identifying a user, such as a registration number registered when using sales system 1, a fan club membership number, or other identification information.

The I/F 26 of the IC card 2 is an interface for contactless IC cards, and is based on the ISO 18092 standard, for example. The CPU 22 of the contactless IC chip 21 transmits and receives information to and from the user ID reading units 32a to 32f of the product panel 3, the user ID reading unit 51 of the register terminal 5, or the user ID reading unit 41 of the correction terminal 4, via the I/F 26 and the antenna 27 in FIG. 2. The antenna 27 runs around the board, and both ends are connected to the contactless IC chip 21.

Next, the configuration of the product panel 3 will be described.
The merchandise panel 3 is a merchandise display device installed within an event venue, and includes a merchandise display unit 30 that displays merchandise or merchandise images, a panel control device 31, and one or more user ID reading units 32a, 32b, 32c, . . .

The panel control device 31 has a memory unit 312 that stores information (product ID) that identifies each product displayed on the product display unit 30, and a control unit 311 that controls the operation of multiple user ID reading units 32a, 32b, 32c, .... FIG. 5 is a diagram showing the configuration of a computer used as the panel control device 31. As shown in FIG. 5, the panel control device 31 is configured by connecting the control unit 311, memory unit 312, communication unit 313, input unit 314, display unit 315, peripheral device I/F unit 316, etc. via a bus 317. The IC card R/W (Reader/Writer) that is the user ID reading units 32a, 32b, 32c, ... shown in FIG. 1 is connected to the peripheral device I/F unit 316. However, the configuration of the panel control device 31 can be changed as appropriate depending on the application.

The control unit 311 is composed of a CPU, ROM, RAM, etc. The CPU loads programs stored in storage media such as the memory unit 312 and ROM into a work area on the RAM and executes them. The ROM is a non-volatile memory, and permanently stores programs such as the boot program and BIOS, data, etc. The RAM is a volatile memory, and temporarily stores programs and data loaded from the memory unit 312, ROM, etc., and also has a work area that the control unit 311 uses to perform various processes.

The memory unit 312 is a hard disk drive, solid state drive, flash memory, etc., and stores the programs executed by the panel control device 31 during the processing described below, data necessary for program execution, the OS, etc. These programs and data are read and executed by the control unit 311 as necessary. The memory unit 312 of the panel control device 31 stores the product ID list 34 (or RW ID list).

Figure 6 is a diagram showing an example of a product ID list 34 (RW ID list). The product ID list 34 is information that associates the user ID reading units (IC card R/W) 32a, 32b, ... provided on each product with the product, and associates the RW ID, which is information that identifies the user ID reading units (IC card R/W) 32a, 32b, ..., with the product ID, which is information that identifies the product. For example, an IC card R/W (user ID reader) 32 with RW ID "01" is associated with a product ID "a", an IC card R/W (user ID reader) 32 with RW ID "02" is associated with a product ID "b", an IC card R/W (user ID reader) 32 with RW ID "03" is associated with a product ID "c", and an IC card R/W (user ID reader) 32 with RW ID "04" is associated with a product ID "d". In this way, when each product is provided with a user ID reader (IC card R/W) 32a, 32b, ..., the RW ID and product ID can both be said to be information that identifies the product.

The communication unit 313 of the panel control device 31 has a communication control device, a communication port, etc., and is a communication interface that mediates communication via the network 7. The panel control device 31 is connected to the server 6, etc. via the network 7, and is capable of transmitting and receiving various data. The network 7 may be a LAN (Local Area Network) or a WAN (Wide Area Network) that is connected for communication over a wider area.
This includes public communication lines such as the Internet, public area network (WAN), and the Internet.

The input unit 314 is, for example, a keyboard, a pointing device such as a mouse, or a touch panel that is integrated with a display, and inputs data to the control unit 311 .
The display unit 315 is composed of a display device such as a liquid crystal panel or a CRT monitor, and a logic circuit (such as a video adapter) for executing display processing in cooperation with the display device, and displays display data input under the control of the control unit 311 on the display device.
The peripheral device I/F unit 316 is a port for connecting peripheral devices such as IC card R/W (user ID reading units) 32a, 32b, . . .

IC card R/W (Reader/Writer) 32a, 32b, ... reads and writes data to and from IC card 2.

When the purchaser holds the IC card 2 over the user ID reading units (IC card R/W) 32a, 32b, ... provided for each product or product image displayed on the product display unit 30, the product panel 3 reads the user ID 251 stored on the IC card 2, and transmits the RW ID (or the product ID stored in association with the RW ID), which is the identification information of the user ID reading unit 32 that read the information on the IC card 2, to the server 6 as purchase intention information 621 in association with the read user ID 251. In this embodiment, when the purchaser holds the IC card 2 over the user ID reading unit (IC card R/W) 32 once, the user ID and RW ID (product ID) of the purchaser are transmitted to the server 6 as purchase intention information 621 for one product. When the same IC card 2 is held twice over the user ID reader (IC card R/W) 32 for the same product, the purchaser's user ID and RW ID (product ID) are sent to the server 6 as two pieces of purchase intention information 621. The server 6 adds and stores the information sent from the product panel 3 (panel control device 31) (user ID, product ID (or RW ID), quantity) to the purchase intention information 621 in the memory unit 62.

Next, the configuration of the server 6 will be described.
As shown in Fig. 1, the server 6 is connected to the product panel 3 (product display device) that displays products, the editing terminal 4, and the cash register terminal 5 via the network 7, and is a device that stores and manages purchase plan information 621 and payment information 622 of each user in the sales system 1. As shown in Fig. 7, for example, the server 6 is composed of a computer or the like to which a control unit 601, a storage unit 602, a communication unit 603, an input unit 604, a display unit 605, a peripheral device I/F unit 606, etc. are connected via a bus 607. The configurations of the control unit 601, the storage unit 602, the communication unit 603, the input unit 604, the display unit 605, and the peripheral device I/F unit 606 are the same as those of the control unit 311, the storage unit 312, the communication unit 313, the input unit 314, the display unit 315, and the peripheral device I/F unit 316 of the panel control device 31, so that the description thereof will be omitted. However, the configuration of the server 6 can be appropriately changed depending on the purpose.

In the sales system 1, the control unit 601 of the server 6 receives information for identifying a product (product ID or RW) from the product panel 3.
The control unit 601 of the server 6 stores the purchase request information 621 in the storage unit 602. The control unit 601 of the server 6 also generates payment information 622 for each user, and transmits it in response to a request from the cash register terminal 5. Details of these processes will be described later.

The storage unit 602 of the server 6 stores purchase plan information 621 and payment information 622. As shown in FIG. 8A, the purchase plan information 621 is information in which records having data items of "user ID", "product ID (or RW ID)", "quantity", and "payment" are accumulated. The user ID, product ID (or RW ID) and payment information are transmitted from the panel control device 31 of the product panel 3.
When the information on the user ID, product ID (or RW ID), and number of items is transmitted, the control unit 601 of the server 6 adds a new record to the purchase schedule information 621, and stores the received user ID, product ID (or RW ID), and number of items in the data items “User ID”, “Product ID (or RW ID)”, and “Number of items”.
The user ID and product ID (or RW ID) and the quantity are stored. The information in the data item "payment" is stored as "not yet" until a notice of payment completion is received from the cash register terminal 5. In the example of FIG. 8, the first record of the purchase intention information 621 stores RW ID "a", quantity "1", and payment "not yet" in association with the user ID "0001". The second record stores RW ID "a", quantity "1", and payment "not yet" in association with the user ID "0002". The third record stores RW ID "b", quantity "1", and payment "not yet" in association with the user ID "0002". The fourth record stores RW ID "c", quantity "2", and payment "not yet" in association with the user ID "0001". In this way, the user ID, product ID (or RW ID) and the quantity "1" are stored from the product panel 3.
Each time the information on the product ID and the number of items is transmitted, it is stored in the purchase candidate information 621 of the server 6 in sequence.

The payment information 622 is information that compiles pending purchase information 621 by user ID, and stores information on the user ID, product ID (or RW ID), and quantity, as shown in FIG. 8(b). When the server 6 receives a payment information acquisition request together with the user ID 251 from the cash register terminal 5, it generates payment information 622 for the corresponding user ID 251 and returns it to the requesting cash register terminal 5. The cash register terminal 5 calculates the total amount based on the received payment information 622 and the product price information 522 stored in the memory unit 502, and performs the payment process.

Next, the configuration of editing terminal 4 will be described.
The editing terminal 4 is a terminal used when the purchaser checks and edits the contents of the purchase schedule information 621 stored in the storage unit 602 of the server 6, and one or more editing terminals are installed in the venue. The editing terminal 4 is composed of a computer or the like to which a control unit 401, a storage unit 402, a communication unit 403, an input unit 404, a display unit 405, a peripheral device I/F unit 406, etc. are connected via a bus 407, as shown in Fig. 9. An IC card R/W, which is a user ID reader 41, is connected to the peripheral device I/F unit 406. The configurations of the control unit 401, the storage unit 402, the communication unit 403, the input unit 404, the display unit 405, and the peripheral device I/F unit 406 are the same as those of the control unit 311, the storage unit 312, the communication unit 313, the input unit 314, the display unit 315, and the peripheral device I/F unit 316 of the panel control device 31, so that the description thereof will be omitted. However, the configuration of the editing terminal 4 can be changed as appropriate depending on the application.

In the sales system 1, the control unit 401 of the editing terminal 4 reads the user ID 251 from the IC card 2, and acquires the purchase intention information 621 corresponding to the read user ID 251 from the server 6. The control unit 401 of the editing terminal 4 displays the acquired purchase intention information 621 on the display unit 405 so that the user can confirm it. The control unit 401 of the editing terminal 4 also accepts corrections to the purchase intention information 621, and transmits the corrected purchase intention information 621 to the server 6. It is also preferable that the control unit 401 of the editing terminal 4 calculates and displays the total price of the products included in the purchase intention information 621. Details of these processes will be described later.

The memory unit 402 of the correction terminal 4 stores a product ID list (RW ID list) 521 and product price information 522 that are the same as the product ID list (RW ID list) 521 and product price information 522 stored in the cash register terminal 5 (see Figure 11).

Next, the configuration of the cash register terminal 5 will be described.
The cash register terminal 5 is a terminal used when a purchaser makes a payment (settlement) for the product stored in the memory unit 602 of the server 6, and one or more cash register terminals are installed in the venue.

For example, when a user (purchaser) reads the user ID 251 from the user ID reading unit (RW
When the user holds the IC card 2 over the user ID reading unit (IC card R/W) 32a, the control unit 311 acquires the RW ID "01" of the user ID reading unit (IC card R/W) 32a, or acquires the RW ID "01" of the user ID reading unit (IC card R/W) 32a by referring to the product ID list 34 in the storage unit 312.
The product ID "a" of the product corresponding to ID "01" is read out.

The control unit 311 (purchase intention information transmission unit 33) of the panel control device 31 of the product panel 3 receives the user ID 251 acquired in step S103 and the product ID or RW acquired in step S104.
The ID and the information on the number of items are transmitted to the server 6 as purchase intention information 621 (step S105). Note that one touch of the IC card 2 counts as one item of the product.

When the server 6 receives the product ID or RW ID and the quantity (one in the case of one touch) together with the user ID, it additionally stores the received information in the purchase intention information 621 in the storage unit 602 (step S106; see FIG. 8(a)). At this stage, the "Payment" item in the purchase intention information 621 is recorded as "Not yet".

The user (purchaser) repeats the operation and holds the IC card 2 over the user ID reading section 32 of the desired product. Each time, the panel control device 31 of the product panel 3 reads the obtained user ID 251 and product ID (or RW
The purchase request information 621 including the product ID and the number of items is transmitted to the server 6 and stored in the server 6 .

If the purchaser wishes to check the contents and quantity of the products sent to the server 6, the purchaser can go to the editing terminal 4 and check or edit the contents and quantity of the products on the editing terminal 4.

The correction process will be described with reference to FIG.
The user (purchaser) holds the IC card 2 over the reading unit 41 (IC card R/W 41) of the editing terminal 4 (step S201). Then, the user ID 251 stored in the IC card 2 is transmitted from the IC card 2 to the editing terminal 4 (step S202). The editing terminal 4 acquires the user ID 251 (step S203).

The control unit 401 (purchase candidate information acquisition unit 42) of the editing terminal 4 transmits a purchase candidate information acquisition request to the server 6 together with the user ID read from the IC card 2 (step S204). When the server 6 receives the purchase candidate information acquisition request and the user ID from the editing terminal 4, it acquires the purchase candidate information 621 corresponding to the received user ID from the storage unit 602 (step S205) and transmits it to the editing terminal 4 that made the request (step S206). When the control unit 401 (purchase candidate information display unit 43) of the editing terminal 4 receives the purchase candidate information 621 (step S207), it displays the contents of the purchase candidate information 621 on the display unit 405. At this time, it is preferable that the control unit 401 (purchase candidate information display unit 43) display information such as product information (product name, price, image, etc.) of the product included in the purchase candidate information 621, the quantity, the total amount, etc., on the display unit 405. In this case, the storage unit 402 of the editing terminal 4 stores the product ID (RW
The control unit 401 (purchase candidate information display unit 43) acquires the product information stored in the storage unit 402, and displays the product name, price, quantity, and image of the product included in the purchase candidate information 621 on the display unit 405, and also calculates the total amount and displays it on the display unit 405.

The control unit 401 (modification unit 44) of the editing terminal 4 accepts modifications to the purchase intention information 621. The purchaser selects the product to be modified via the input unit 404 of the editing terminal 4, changes the quantity, and adds or deletes products (step S208). When the modifications are made, the control unit 401 (total amount display unit 46) of the editing terminal 4 calculates the total amount of the products based on the modified content and displays it on the display unit 405 (step S209). Modifications are accepted until the purchaser checks the displayed total amount and inputs an instruction to reflect the modified content (step S210; No → step S208). The control unit 401 (total amount display unit 46) of the editing terminal 4 calculates the total amount of the products each time the content of the purchase intention information 621 is modified, and displays it on the display unit 405 (step S209).

After that, when the purchaser inputs an instruction to reflect the revised content (step S210; Yes), the control unit 401 (revised information transmission unit 45) of the revision terminal 4 transmits the revised purchase intention information 621 to the server 6 (step S211). When the server 6 receives the revised purchase intention information 621, it updates and stores the purchase intention information 621 in the storage unit 602 (step S212).

Next, the payment process will be described with reference to FIG.
The user (purchaser) holds the IC card 2 over the user ID reading section (IC card R/W) 51 of the cash register terminal 5 (step S301). Then, the user ID 251 stored in the IC card 2 is transmitted from the IC card 2 to the cash register terminal 5 (step S302). The cash register terminal 5 acquires the user ID 251 (step S303).

The control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 transmits a payment information acquisition request to the server 6 together with the user ID read from the IC card 2 (step S304). When the server 6 receives the payment information acquisition request and the user ID 251 from the cash register terminal 5, it acquires the purchase intention information 621 corresponding to the received user ID 251 from the storage unit 602 and generates payment information 622 (step S305). It then transmits this to the cash register terminal 5 that made the request (step S306). When the control unit 501 (payment information acquisition unit 52) of the cash register terminal 5 receives the payment information 622 (step S307), it performs payment processing based on the received payment information 622 (step S308). In step S308, the control unit 501 (payment processing unit 54) of the cash register terminal 5 acquires the product ID (RW) included in the payment information 622.
The control unit 501 (payment processing unit 54) obtains price information corresponding to the product ID from product price information 522 stored in the memory unit 502. The control unit 501 (payment processing unit 54) also calculates the total amount of the products based on the product prices and quantities. The control unit 501 (payment processing unit 54) of the cash register terminal 5 displays the total amount on the display unit 505 to inform the purchaser. The cash register terminal 5 performs payment processing using cash, credit card, electronic money, etc. In the payment processing, a receipt is output from the receipt printer 508 on which the product name, quantity, price, total amount, change amount, etc. are printed.

When the payment process is complete, the control unit 501 (payment completion information sending unit 55) of the cash register terminal 5 sends payment completion information to the server 6 (step S309). The control unit 601 (payment completion processing unit 65) of the server 6 changes the "Payment" item in the purchase intention information 621 stored in the memory unit 602 for the item for which payment has been completed from "Not yet" to "Completed," or deletes the record of the item for which payment has been completed from the purchase intention information 621 (step S310). The cashier clerk hands the purchaser the receipt printed from the cash register terminal 5 and guides them to the product pick-up counter. The purchaser goes to the product pick-up counter and picks up all of the purchased items at once.

It is also possible for the cash register terminal 5 to accept corrections. In that case, the cash register terminal 5 executes the processes from step S201 to step S210 in FIG. 14. Then, in the payment process of step S308, the payment process is performed based on the corrected payment information 622.

As described above, the sales system 1 according to the first embodiment includes the product panel 3 on which the user ID reading unit 32 is provided for each product. When a purchaser holds the IC card 2 over the user ID reading unit (IC card R/W) 32 corresponding to the product he or she wants, the identification information (product ID or RW) of the product is read.
The user ID 251 and the user ID 252 are transmitted to the server 6 together with the user ID 251 and stored as the user's purchase plan information 621. The cash register terminal 5 obtains from the server 6 the payment information 622 corresponding to the user ID 251 read from the IC card 2, calculates the total amount of the products based on the product price information and the like, and performs the payment process. As a result, the user (purchaser) can specify the product and record the product ID by simply holding the IC card 2 over the product (user ID reading unit 32) he or she wants, so the purchaser does not need to take notes of the product he or she wants or verbally tell the cashier, and the purchase of the product becomes smooth. In addition, since the purchase plan information 621 is written to the server 6, it is only necessary to store the user ID in the IC card 2, and the IC card 2 can be used regardless of its storage capacity.

In the above description, each time a user (purchaser) holds the IC card 2 over the user ID reading unit 32 of a desired product, the panel control device 31 of the product panel 3 acquires the user ID 251 and reads the user ID and product ID (or RW
In the above example, the server 6 is configured to store the information on the number of products as the purchase request information 621, but the procedure is not limited to this. For example, when the user holds the IC card 2 over multiple products (user ID reading unit 32) in succession, the product ID (or RW) for those products is collectively transmitted to the server 6 and stored in the server 6 as the purchase request information 621.
Alternatively, information on the number of pieces of the user ID and the number of pieces of the user ID may be transmitted to the server 6 together with the user ID.

[Second embodiment]

At this stage, the "Payment" item is stored as "Not yet" (step S404; FIG. 21(a)).

By carrying out the correction process in FIG. 24, the user (purchaser) can confirm and correct the purchase intention information 621 stored in the server 6. The correction process will be described below with reference to FIG. 24 and FIG. 25.

When a user (purchaser) inputs an instruction to display the purchase intention information 621 to the mobile terminal 8 (step S501), the control unit 801 (purchase intention information acquisition unit 87) of the mobile terminal 8 sends a purchase intention information acquisition request together with the user ID 81 stored in the memory unit 802 to the server 6 (step S502). In response to the purchase intention information acquisition request from the mobile terminal 8, the server 6 acquires the purchase intention information 621 corresponding to the user ID 81 from the memory unit 602 (step S503) and sends it to the mobile terminal 8 (step S504).

When the control unit 801 of the mobile terminal 8 receives the purchase request information 621 (step S505), it displays the received purchase request information 621 on the correction screen 853 (step S506). As shown in FIG. 25, the correction screen 853 displays images 853a and 853c of the products included in the purchase request information 621, as well as a purchase button 853b operated when making an additional purchase, a delete button 853d operated when deleting, and a quantity change input field (not shown). It is preferable that the correction screen 853 displays information such as the product name, description, and price in addition to the product images 853a and 853c. The control unit 801 may also calculate the total price of the products included in the purchase request information 621 based on the product information 82 stored in the memory unit 802, and display the calculated price on the correction screen 853.

The control unit 801 (modification unit 88) of the mobile terminal 8 accepts the input of the modifications. The purchaser selects the products to be modified, changes the quantity, and adds or deletes products via the input unit 804 of the mobile terminal 8 (step S507). When the modifications are input, the control unit 801 of the mobile terminal 8 calculates the total price of the products based on the modified content and displays it on the display unit 805 (step S508). Modifications are accepted until the purchaser confirms the displayed total price and inputs an instruction to reflect the modified content (step S509; No). The control unit 801 of the mobile terminal 8 calculates the total price of the products each time the content of the purchase intention information 621 is modified, and displays it on the display unit 405.

After that, when the purchaser inputs an instruction to reflect the revised content (step S509; Yes), the control unit 801 (revised information transmission unit 89) of the mobile terminal 8 transmits the revised purchase intention information 621 to the server 6 (step S510). When the server 6 receives the revised purchase intention information 621, it updates and stores the purchase intention information 621 in the storage unit 602 (step S511).

Next, a settlement process in the sales system 1B according to the third embodiment will be described with reference to FIG.
First, the user operates the mobile terminal 8 to display a QR code (registered trademark) 855 indicating the user ID 81 on the display unit 805. The control unit 801 (QR code (registered trademark) display unit 83) of the mobile terminal 8 converts the user ID 81 stored in the storage unit 802 into the form of a QR code (registered trademark) and displays it on the display unit 805 (step S601). FIG. 27 is a diagram showing an example of a state in which the QR code (registered trademark) 855 is displayed on the display unit 805 of the mobile terminal 8. The user ID 81 may be displayed on the display unit 805 together with the QR code (registered trademark) 855. This allows the user ID 81 to be manually input into the cash register terminal 5 even if a malfunction occurs in the code reading unit 57.

The user (purchaser) holds the QR code (registered trademark) 855 displayed on the mobile terminal 8 over the code reading unit 57 of the cash register terminal 5 (step S602). The code reading unit 57 of the cash register terminal 5 reads the QR code (registered trademark) 855 and obtains the user ID 81 (step S603).

The control unit 501 (payment information acquisition unit 52) of the cashier terminal 5 sends a payment information acquisition request to the server 6 together with the acquired user ID (step S604). When the server 6 receives the payment information acquisition request and the user ID 81 from the cashier terminal 5, it acquires the purchase plan information 621 corresponding to the received user ID 81 from the storage unit 602 and generates payment information 622 (step S605). Then, it transmits the payment information 622 to the requesting cashier terminal 5 (step S606). When the control unit 501 (payment information acquisition unit 52) of the cashier terminal 5 receives the payment information 622 (step S607), it performs payment processing based on the received payment information 622 (step S608). The control unit 501 (payment processing unit 54) of the cashier terminal 5 acquires price information corresponding to the product ID included in the payment information 622 from the product information 531 stored in the storage unit 502. The control unit 501 (payment processing unit 54) also calculates the total amount of the products based on the price and number of the products. The control unit 501 (payment processing unit 54) of the cash register terminal 5 displays the total amount on the display unit 505 and informs the purchaser. The cash register terminal 5 performs payment processing using cash, credit card, electronic money, etc. In the payment processing, a receipt is output from the receipt printer 508 on which the product name, quantity, price, total amount, change amount, etc. are printed.

When the payment process is complete, the control unit 501 (payment completion information sending unit 55) of the cash register terminal 5 sends payment completion information to the server 6 to update it (step S609). For example, the control unit 601 of the server 6 changes the "Payment" item in the purchase intention information 621 stored in the memory unit 602 for the item for which payment has been completed from "Not yet" to "Completed". Alternatively, the control unit 601 deletes the record of the item for which payment has been completed from the purchase intention information 621 (step S610). The cashier clerk hands the receipt to the purchaser and guides them to the product pick-up window.

The purchaser goes to the product collection counter and receives all the purchased items together.

The cash register terminal 5 can also accept corrections to the products included in the payment information 622. In that case, the cash register terminal 5 executes the processes from step S501 to step S510 in FIG. 24. Then, in the payment process of step S608, the cash register terminal 5 performs the payment process based on the corrected payment information 622.

As described above, according to the sales system 1B of the third embodiment, the user can select the product to be purchased on the mobile terminal 8. Information on the selected product and the number of pieces is sent to the server 6 and managed by the server 6 as purchase plan information 621. When making payment for the product, the user ID 81 is input to the cash register terminal 5 by displaying a QR code (registered trademark) 855 indicating the user ID 81 on the display unit 805 of the mobile terminal 8 and reading it with the code reading unit 57 of the cash register terminal 5. The cash register terminal 5 can obtain payment information 622 corresponding to the user ID 81 from the server 6 and make a payment. As a result, the user can select the product he or she wants on the mobile terminal 8 while waiting in line at the cash register at a sales venue for goods, etc., and send it to the server 6, and the cash register terminal 5 can smoothly make a payment for the product and receive the product by simply displaying and reading the QR code (registered trademark) 81 on the mobile terminal 8 at the cash register terminal 5. The purchaser does not need to walk around the venue to select the product he or she wants, or to verbally tell the cash register staff which product he or she wants, which makes the purchase of the product smooth. In addition, in the third embodiment, unlike the sales system 1 of the first embodiment and the sales system 1A of the second embodiment, there is no need to provide a product panel 3 or a correction terminal 4, and there is no need to place a reading unit (IC card R/W or code reader) on each displayed product, so the device configuration is simplified and costs can be reduced.

The above describes preferred embodiments of the present invention with reference to the attached drawings, but the present invention is not limited to these examples. It is clear that a person skilled in the art can come up with various modified or revised examples within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally fall within the technical scope of the present invention.
