Description

An embodiment of the present invention relates to a product purchase management device and a program for operating a computer as a product purchase management device.

In recent years, from the viewpoint of environmental protection, many supermarkets have been refraining from using plastic shopping bags and recommending the use of bags brought by customers, so-called my bags. Such efforts are commonly referred to as the My Bag movement. Stores where the My Bag campaign is carried out usually do not provide shopping bags to customers who use My Bags. However, depending on the number of purchased products and the individual volume, the products may not fit in the My Bag brought by the customer. In such a case, the clerk provides the customer with a plastic shopping bag.

In connection with this, conventionally, when the capacity of the shopping bag brought by the customer is insufficient for the sum of the individual volumes of the products purchased by the customer, a device that displays the number of shopping bags corresponding to the insufficient capacity has been used. Are known. However, in such a conventional device, it is necessary to make the device read the information of the information recording medium attached to the my bag in order to make the device set the capacity of the my bag. Therefore, the My Bag without the information recording medium cannot be used, and the usable My Bag is restricted. Originally, the My Bag movement can be carried by the customer in any bag or bag, so there is a problem that the conventional device cannot promote the My Bag movement.

The processor 31 waits for the "Yes" button B1 to be input or the "No" button B2 to be input (Act4). When the "Yes" button B1 is input (Act4, YES), the processor 31 executes the My Bag registration process (Act5). Then, when the My Bag registration process is completed, the processor 31 switches the screen of the display device 36 to the home screen SC2 (see FIG. 11) (Act6). On the other hand, when the "No" button B2 is input (Act4, NO), the processor 31 skips the my bag registration process and switches the screen of the display device 36 to the home screen SC2 (Act6).

12A, 12B, and 12C are flow charts specifically showing the procedure of the My Bag registration process. Upon entering the my bag registration process, the processor 31 requests the electronic receipt server 10 for the registered list (Act 21). That is, the processor 31 generates a request command for the registered list including the receipt member code stored in the memory 332. Then, the processor 31 controls the wireless module 34 and wirelessly transmits this request command to the electronic receipt server 10.

The wirelessly transmitted request command is received by the base station 50 and sent to the electronic receipt server 10 via the communication network 40.
FIG. 17 is a flow chart showing a procedure of main command reception processing executed by the processor 11 of the electronic receipt server 10. As shown in the figure, when the processor 11 receives a command, the processor 11 determines the type of the command (Act51, Act61, Act71, Act81).

Here, when the received command is a request command of the registered list (Act51, YES), the processor 11 searches the member database 132 and obtains the record 132R in which the receipt member code included in the request command is set. To detect. Then, the processor 11 creates a registered list based on the my bag list 73 of the record 132R (Act 52). As an example, the registered list is a list of identification names included in the My Bag list 73. Therefore, if no data is registered in the My Bag list 73, an empty registered list is created. The processor 11 controls the communication interface 14 to transmit a response command including the registered list to the information terminal 30 of the request command transmission source (Act 53).

The response command is wirelessly transmitted from the base station 50 via the communication network 40, and is received by the information terminal 30 from which the request command is transmitted.
The explanation is returned to FIG. 12A. The processor 31 of the information terminal 30 that has transmitted the request command listens for the response command (Act 22). Then, when the response command is received (Act22, YES), the processor 31 causes the display device 36 to display the registered list screen SC3 (see FIG. 13) showing the registered list included in the response command (see FIG. 13). Act23).

FIG. 13 is a display example of the registered list screen SC3. On the registered list screen SC3, three "Yes" buttons B5, B6, and B7 are displayed together with the registered list L1. As described above, the registered list L1 lists the identification names of My Bag. The My Bag specified by the identification name displayed in the registered list L1 has already been registered by the member specified by the receipt member code stored in the memory 332 of the information terminal 30. The "Yes" button B5 is a button for the member to operate when adding a new My Bag. The "Yes" button B6 is a button for the member to operate when deleting an unnecessary My Bag from the registered My Bags. The "Yes" button B7 is a button to be operated when the member finishes the My Bag registration. Hereinafter, for convenience of explanation, the "Yes" button B5 will be referred to as an add button B5, the "Yes" button B6 will be referred to as a "delete" button B6, and the "yes" button B7 will be referred to as an "end" button B7.

The processor 31 displaying the registered list screen SC3 confirms whether or not the add button B5 has been input (Act 24). When the add button B5 is not input (Act24, NO), the processor 31 confirms whether or not the delete button B6 is input (Act25). When the delete button B6 is not input (Act25, NO), the processor 31 confirms whether or not the end button B7 is input (Act26). When the end button B7 is not input (Act26, NO), the processor 31 confirms whether or not the add button B5 is input again (Act24). Thus, the processor 31 waits for any of the add button B5, the delete button B6, and the end button B7 to be input in the processing of Act24, Act25, and Act26.

When the processor 31 confirms the input of the additional button B5 in the standby state of Act24 to Act26 (Act24, YES), the processor 31 shifts to the process shown in FIG. 12B. Specifically, the processor 31 requests the electronic receipt server 10 for my bag data (Act 27). That is, the processor 31 generates a request command for my bag data. Then, the processor 31 controls the wireless module 34 and wirelessly transmits this request command to the electronic receipt server 10.

The wirelessly transmitted request command is received by the base station 50 and sent to the electronic receipt server 10 via the communication network 40.
As shown in FIG. 17, when the received command is a request command for my bag data (Act61, YES), the processor 11 of the electronic receipt server 10 displays each record 133R stored in the my bag database 133. Acquire (Act62). Then, the processor 11 controls the communication interface 14 and transmits the response command including the record 133R data acquired from the My Bag database 133, that is, the so-called My Bag data, to the information terminal 30 of the request command transmission source (Act 63). ).

The response command is wirelessly transmitted from the base station 50 via the communication network 40, and is received by the information terminal 30 from which the request command is transmitted.
The explanation is returned to FIG. 12B. The processor 31 of the information terminal 30 that has transmitted the request command listens for the response command (Act 28). Then, when the response command is received (Act 28, YES), the processor 31 creates a candidate list from the My Bag data included in the response command (Act 29). That is, the processor 31 excludes the data of the record 133R including the identification name existing in the registered list from the my bag data. Then, the processor 31 creates a candidate list listing the identification names included in the remaining my bag data. The processor 31 causes the display device 36 to display the candidate list screen SC4 (see FIG. 14) showing the candidate list (Act 30).

FIG. 14 is a display example of the candidate list screen SC4. On the candidate list screen SC4, the previous page button B8, the next page button B9, the execute button B10, and the cancel button B11 are displayed together with the candidate list L2. Further, the image icon A1 and the selection icon A2 are displayed for each identification name of the candidate list L2.

It is considered that the identification names of many my bags are displayed in the candidate list L2. On the other hand, since the screen size of the display device 36 is limited, it is assumed that the candidate list L2 spans a plurality of pages. The previous page button B8 is a button for the member to operate when he / she wants to confirm the candidate list L2 on the previous page. The next page button B9 is a button for the member to operate when he / she wants to confirm the candidate list L2 on the previous page.

The image icon A1 is an icon for the member to operate when he / she wants to confirm the My Bag image of the corresponding identification name. Incidentally, when the image icon A1 is input, the processor 31 causes the display device 36 to display the My Bag image having the identification name corresponding to the image icon A1. At this time, a back button is displayed on the screen of the display device 36, and when this back button is input, the processor 31 returns the screen of the display device to the candidate list screen SC4.

The selection icon A2 is an icon for the member to operate when he / she wants to register the My Bag having the corresponding identification name. Incidentally, when the selection icon A2 is input, the processor 31 notifies the user (member) that the selection icon A2 is in the selected state as a special display such as blinking or reversing the identification name corresponding to the selection icon A2.

The execution button B10 is a button to be operated when the member commands the addition of the My Bag specified by the identification name in the selected state.
The cancel button B11 is a button for the member to operate when the process of adding the my bag is terminated without adding the my bag.

For example, it is assumed that a member who has confirmed the registered list screen SC3 shown in FIG. 13 operates the add button B5 to display the candidate list screen SC4 shown in FIG. In this example, when it is desired to add the My Bag specified by the identification name "Commercial product 30L", the member inputs the selection icon A2 corresponding to the identification name "Commercial product 30L" and then the execution button B10. Similarly, if a member wants to add a my bag specified by the identification name "commercial product 30L" and a my bag specified by the identification name "C super (large)", the member has the identification name "commercial product 30L" and the identification name. After inputting the selection icon A2 corresponding to "C super (large)", input the execute button B10.

The processor 31 displaying the candidate list screen SC4 confirms whether or not the execution button B10 is input with the identification name of the My Bag selected by the selection icon A2 (Act31). When the execute button B10 is not input, or when the execute button B10 is input without selecting the identification name (Act31, NO), the processor 31 confirms whether or not the cancel button B11 is input (Act32). .. When the cancel button B11 is not input (Act32, NO), the processor 31 confirms whether or not the execution button B11 is input with the identification name selected again (Act31). Here, in the processing of Act31 and Act32, the processor 31 waits for the execution button B10 to be input or the cancel button B11 to be input with the identification name selected.

When the execute button B10 is input with the identification name selected (Act31, YES), the processor 31 generates an additional request command including the selected identification name and the receipt member code stored in the memory 332. To do. Then, the processor 31 wirelessly transmits this additional request command to the electronic receipt server 10 (Act 33).

The wirelessly transmitted additional request command is received by the base station 50 and sent to the electronic receipt server 10 via the communication network 40.
As shown in FIG. 17, the processor 11 of the electronic receipt server 10 searches the member database 132 when the received command is an additional request command (Act71, YES). Then, the processor 11 stores the identification name included in the additional request command in the My Bag database 133 together with the identification name in the My Bag list of the record 132R in which the receipt member code included in the additional request command is set. Add with my bag ID and capacity (Act72). Further, the processor 31 recreates the registered list with the data of the My Bag list after adding the data (Act73). Then, the processor 11 controls the communication interface 14 to transmit a response command including a new registered list to the information terminal 30 of the request command transmission source (Act 74).
Here, the processor 11 of the electronic receipt server 10 functions as a registration means by executing the process of Act 72.

The response command is wirelessly transmitted from the base station 50 via the communication network 40, and is received by the information terminal 30 from which the request command is transmitted.
The explanation is returned to FIG. 12B. The processor 31 of the information terminal 30 that has transmitted the additional request command listens for the response command (Act 34). Then, when the response command is received (Act34, YES), the processor 31 erases the candidate list screen SC4 (Act35). After that, the processor 31 returns to the process of Act23 described above, and displays the registered list screen SC3 on the display device 36. The registered list displayed on the registered list screen SC3 at this time is the registered list included in the response command received in Act34.

Therefore, for example, when a member who has confirmed the registered list screen SC3 shown in FIG. 13 adds a my bag with the identification name “commercially available product 30L”, the registered list screen SC3 including the registered list L1a shown in FIG. 15 is displayed. To.

When the cancel button B11 is input in the standby state of Act31 and Act32 (Act32, YES), the processor 31 skips the processing of Act33 and Act34 and proceeds to the processing of Act35. That is, the processor 31 erases the candidate list screen SC4 (Act35). After that, the processor 31 returns to the process of Act23 described above, and displays the registered list screen SC3 on the display device 36. However, since the response command has not been received at this point, the registered list displayed on the registered list screen SC3 is the same as the registered list L1 before the add button B5 is input.

When the processor 31 confirms the input of the delete button B6 in the standby state of Act24 to Act26 (Act25, YES), the processor 31 shifts to the process shown in FIG. 12C. Specifically, the processor 31 causes the display device to display the deletion candidate screen SC5 (see FIG. 16) (Act 36).

FIG. 16 is a display example of the deletion candidate screen SC5. On the deletion candidate screen SC5, the execution button B12 and the cancel button B13 are displayed together with the registered list L1 of the registered list screen SC3. In addition, the selection icon A3 is displayed for each identification name in the registered list L1.

The selection icon A3 is an icon for the member to operate when he / she wants to delete the My Bag having the corresponding identification name. Incidentally, when the selection icon A3 is input, the processor 31 notifies the user (member) that the selection icon A3 is in the selected state as a special display such as blinking or reversing the identification name corresponding to the selection icon A3.

The execution button B12 is a button to be operated when the member commands the deletion of the My Bag specified by the identification name in the selected state.
The cancel button B13 is a button for the member to operate when the member deletes the my bag without deleting the my bag.

The processor 31 displaying the deletion candidate screen SC5 confirms whether or not the execution button B12 is input with the identification name of the My Bag selected by the selection icon A3 (Act37). If the execute button B12 is not input, or if the execute button B12 is input without selecting the identification name (Act37, NO), the processor 31 confirms whether or not the cancel button B13 is input (Act38). .. When the cancel button B13 is not input (Act38, NO), the processor 31 confirms whether or not the execution button B12 is input with the identification name selected again (Act37). Here, in the processing of Act 37 and Act 38, the processor 31 waits for the execution button B12 to be input or the cancel button B13 to be input with the identification name selected.

When the execute button B12 is input with the identification name selected (Act37, YES), the processor 31 generates a deletion request command including the selected identification name and the receipt member code stored in the memory 332. To do. Then, the processor 31 wirelessly transmits this deletion request command to the electronic receipt server 10 (Act 39).

The wirelessly transmitted deletion request command is received by the base station 50 and sent to the electronic receipt server 10 via the communication network 40.
As shown in FIG. 17, the processor 11 of the electronic receipt server 10 searches the member database 132 when the received command is a deletion request command (Act81, YES). Then, the processor 11 deletes the data including the identification name included in the deletion request command from the My Bag list of the record 132R in which the receipt member code included in the deletion request command is set (Act 82). Further, the processor 31 recreates the registered list with the data of the My Bag list after deleting the data (Act83). Then, the processor 11 controls the communication interface 14 to transmit a response command including a new registered list to the information terminal 30 of the request command transmission source (Act 84).

The response command is wirelessly transmitted from the base station 50 via the communication network 40, and is received by the information terminal 30 from which the request command is transmitted.
The explanation is returned to FIG. 12C. The processor 31 of the information terminal 30 that has transmitted the deletion request command listens for the response command (Act 40). Then, when the response command is received (Act40, YES), the processor 31 erases the deletion candidate screen SC5 (Act41). After that, the processor 31 returns to the process of Act23 described above, and displays the registered list screen SC3 on the display device 36. The registered list displayed on the registered list screen SC3 at this time is the registered list included in the response command received in Act40.

When the cancel button B13 is input in the standby state of Act37 and Act38 (Act38, YES), the processor 31 skips the processing of Act39 and Act40 and proceeds to the processing of Act41. That is, the processor 31 erases the deletion candidate screen SC5 (Act 41). After that, the processor 31 returns to the process of Act23 described above, and displays the registered list screen SC3 on the display device 36. The registered list displayed on the registered list screen SC3 at this time is the same as the registered list L1 before the delete button B6 is input.

When the processor 31 confirms the input of the end button B7 in the standby state of Act24 to Act26 (Act26, YES), the processor 31 deletes the registered list screen SC3 (Act42). With the above, the processor 31 exits the my bag registration process. After that, the processor 31 causes the display device 36 to display the home screen SC2 as Act 6 in FIG.

FIG. 11 is a display example of the home screen SC2. On the home screen SC2, in addition to the barcode symbol C1 representing the receipt member code stored in the memory 332 and various menu buttons B3, the "Yes" button B4 to be operated when the member has my bag is displayed. Is displayed. The home screen SC2 is used when a member purchases a product at a member store of an electronic receipt service and receives a receipt representing the transaction content as electronic data.

Therefore, next, the operation of the member purchasing the product at the member store of the electronic receipt service and making the payment will be described separately for the case where the member is the main body and the case where the member store clerk is the main body. First, the operation when the member is the main body will be described with reference to FIGS. 9 and 11.
A member who purchases a product at a member store causes the display device 36 of the information terminal 30 to display the home screen SC2 before making a payment. Then, the member who brings my bag inputs the "Yes" button B4. Members who do not bring their own bags do not press the "Yes" button B4. After that, the member presents the home screen SC2 to the clerk in charge of settlement in the settlement at the accounting place where the POS terminal 20 is placed.

The processor 31 of the information terminal 30 that displays the home screen SC2 on the display device 36 confirms whether or not the “Yes” button B4 of the home screen SC2 has been input (Act7). If not input (Act7, NO), the processor 31 confirms whether or not the end of the electronic receipt program 331 is instructed (Act8). If the end of the electronic receipt program 331 is not instructed (Act8, NO), the processor 31 confirms whether or not the "Yes" button B4 has been input again (Act7). Here, the processor 31 waits for the "Yes" button B4 to be input or the end of the electronic receipt program 331 to be instructed in Act7 and Act8.

In this standby state, when the "Yes" button B4 is input (Act7, YES), the processor 31 generates a bring-in command including the receipt member code stored in the memory 332. Then, the processor 31 controls the wireless module 34 and wirelessly transmits this bring-in command to the electronic receipt server 10.

The wirelessly transmitted bring-in command is received by the base station 50 and sent to the electronic receipt server 10 via the communication network 40.
The processor 11 of the electronic receipt server 10 that has received the bring-in command searches the member database 132 and changes the bring-in flag 74 of the record 132R in which the receipt member code included in the bring-in command is set from "0" to "1". rewrite. That is, the processor 11 remembers that the member specified by the receipt member code brings my bag.

The processor 31 of the information terminal 30 that has transmitted the bring-in command returns to the standby state of Act7 and Act8 again. In this standby state, when the end of the electronic receipt program 331 is instructed (Act8, YES), the processor 31 erases the home screen SC2 (Act10). With the above, the processor 31 ends the information processing according to the electronic receipt program 331.

Next, the operation when the clerk of the member store is the main body will be described with reference to FIGS. 18 to 23.
FIG. 18 is a flow chart showing a main information processing procedure executed by the processor 21 in response to a read input performed by the reading device 27. FIG. 19 is a flow chart showing a main information processing procedure executed by the processor 21 in response to the registration of the product. FIG. 20 is a flow chart showing a main information processing procedure executed by the processor 21 in response to a closing input. 21 to 23 are views showing a display example of the My Bag selection screen described later. Incidentally, the information processing shown by the flow charts of FIGS. 18 to 20 follows the program stored in the main memory 22 or the auxiliary storage device 23.

When the clerk receives the presentation of the home screen SC2 from the member, the store clerk causes the reading device 27 to read the barcode symbol C1 displayed on the home screen SC2.

When the data is read through the reading device 27, the processor 21 starts information processing of the procedure shown in the flow chart of FIG. First, the processor 21 confirms whether or not the data read through the reading device 27 is the receipt member code of the barcode symbol C1 (Act101). When the barcode symbol data other than the receipt membership code is read, for example, when the barcode symbol data (product code) attached to the product is read (Act101, NO), the processor 21 reads the data. Execute the corresponding process.

When the receipt member code is read (Act101, YES), the processor 21 stores the receipt member code in the work area of the main memory 22 and then examines the first flag area 221 (Act102). Here, when the first flag F1 of the first flag area 221 is set to "1" (Act52, NO), the processor 21 makes the reading of the barcode symbol C1 an error.

When the first flag F1 of the first flag area 221 is reset to "0" (Act102, YES), the processor 21 sets the first flag F1 to "1" (Act103). That is, the processor 21 stores information indicating that the transaction is with a member of the electronic receipt service.
Here, the processor 21 of the POS terminal 20 functions as a customer identification means by executing the processes of Act 101 to Act 103 in cooperation with the reading device 27 which is a reading unit.

The processor 21 also generates a My Bag bring confirmation command including the receipt membership code. Then, the processor 21 controls the communication interface 24 and transmits this confirmation command to the electronic receipt server 10 as a destination (Act 104).

The transmitted confirmation command is sent to the electronic receipt server 10 via the communication network 40.
The processor 11 of the electronic receipt server 10 that has received the confirmation command searches the member database 132, and each data of the my bag list, the bring flag, and the my bag history of the record 132R in which the receipt member code included in the confirmation command is set. Is detected. Then, the processor 11 controls the communication interface 14 and transmits a response command including the data detected from the member database 132 to the POS terminal 20 that is the source of the confirmation command.

The response command is received by the POS terminal 20 from which the confirmation command is transmitted via the communication network 40.
The processor 21 that has transmitted the confirmation command listens for the response command, and when it receives the response command, examines the bring flag included in the response command (Act105). Here, when the bring flag is "0", that is, in the case of a transaction with a member who does not bring my bag (Act105, NO), the processor 21 ends the process for the read input.

When the bring flag is "1", that is, in the case of a transaction with a member who brings my bag (Act 105, YES), the processor 21 detects the my bag list 73 from the response command (Act 106). Further, the processor 21 detects the my bag history 75 from the response command (Act107). Then, the processor 21 determines the priority of the my bag owned by the member from the data of the my bag list 73 and the data of the my bag history 75 (Act 108).

For example, the processor 21 extracts the My Bag ID associated with the store code of the store in which the POS terminal 20 is operating from the My Bag history 75. Then, the processor 21 sets the my bag specified by the extracted my bag ID as the first priority. Here, when a plurality of types of My Bag IDs associated with the same store code are extracted, the processor 21 ranks the one with the largest number extracted from the My Bag history 75, that is, the one with the highest number of uses. Next, among the My Bag IDs existing in the My Bag List 73, the processor 21 has a larger number of My Bag IDs whose priority is not set, that is, the number of times of use, which is stored in the My Bag History 75. The one with the most is ranked high. If the number of times of use is the same, the order is as registered in the My Bag List 73.

The processor 21 causes the display device 26 to display the My Bag selection screen SC6 (see FIGS. 21, 22, and 23) in which the identification names of the My Bag list 73 are arranged in descending order of priority (Act109).

21 to 23 are display examples of the My Bag selection screen SC6. Examples of this are the original type my bag "A supermarket (small)" sold at the member store "A supermarket" and the original type my bag "C supermarket (large)" sold at the member store "C supermarket". It relates to a member who owns four types of commercial type my bags, "commercial product 15L" and "commercial product 30L". And from the member's my bag history 75, the number of individual uses is 10 times for my bag "A super (small)", 5 times for my bag "C super (large)", and my bag "commercial item 15L". It is assumed that my bag "commercial product 30L" is 8 times and 12 times.

FIG. 21 is a my bag selection screen SC6 when this member makes a transaction at the member store “C supermarket”. As shown in FIG. 21, the original type of the member store “C supermarket”, my bag “C supermarket (large)”, is at the top. For other my bags, they are used in descending order of frequency of use.

FIG. 22 is a my bag selection screen SC6 when this member makes a transaction at the member store “A supermarket”. As shown in FIG. 22, my bag "A supermarket (small)", which is an original type of the member store "A supermarket", is at the top. For other my bags, they are used in descending order of frequency of use.

FIG. 23 is a My Bag selection screen SC6 when the member conducts a transaction at a member store other than the member store “A supermarket” and the member store “C supermarket”. As shown in FIG. 23, the my bag "commercially available product 30L", which is used most frequently, is the highest. The other My Bags are also used in descending order of frequency of use.

Here, the processor 21 functions as a display means by executing the processes of Act 106 to Act 109 in cooperation with the display device.

The processor 21 that displays the my bag selection screen SC6 waits for my bag to be selected from the list displayed on the my bag selection screen SC6 (Act110).
In the POS terminal 20, the display device 26 often includes two types, a clerk side and a customer side. When the selection screen SC6 is displayed on the display device 26 on the clerk side, the processor 21 waits for my bag to be selected via the input device 25 such as a keyboard or touch panel operated by the clerk. On the other hand, when displaying on the display device 26 on the customer side, the display device 26 on the customer side is used as a touch panel. Then, the processor 21 waits for my bag to be selected via this touch panel.

When My Bag is selected (Act110, YES), the processor 21 sets the second flag F2 of the second flag area 222 to “1” (Act111). Further, the processor 21 writes the My Bag ID and the identification name of the selected My Bag in the My Bag Memory 226 (Act112). Further, the processor 21 writes the capacity of the selected My Bag to the capacity memory 227 (Act113). With the above, the processor 21 ends the process for the read input.
Here, the processor 21 functions as a selection means by executing the processing of Act 110 to Act 113 in cooperation with the input device 25.

Now, the clerk operates the reading device 27 or the input device 25 to register the product to be purchased by the member.
When the product code is read through the reading device 27 or the product code is input via the input device 25, the processor 21 recognizes that the product to be purchased by the customer has been registered. Then, the processor 21 starts information processing of the procedure shown in the flow chart of FIG.

First, the processor 21 examines the third flag F3 in the third flag area 223 (Act121). The third flag is reset to "0" when the first point of the first transaction is not registered, and is set to "1" when the first point is registered. When the third flag F3 is reset to "0" (Act121, YES), the processor 21 sets the third flag F3 to "1" (Act122). The processor 21 also initializes the transaction memory 224 (Act123). Further, the processor 21 sets the value V of the total volume memory 225 to “0” (Act124). When the third flag F3 is set to "1" (Act121, NO), the processor 21 skips the processing of Act122 to Act124.

The processor 21 executes the registration process of the product sales data (Act125). That is, the processor 21 searches the product database 231 with the product code input via the reading device 27 or the input device 25, and reads the data of the record 231R in which the product code is set. Then, the processor 21 calculates the sales amount by multiplying the price of this data by the number of sales points, and generates product sales data including the product code, the product name, the price, the number of sales points, and the sales amount. The number of items sold is the numerical value when the numerical value is placed before the product code is input, and is "1" when the numerical value is not placed. The processor 21 writes the product sales data in the transaction memory 224. Further, the processor 21 causes the display device to display the product name, the price, the number of items sold, and the sales amount.
Here, the processor 21 functions as a product identification means by executing the processes of Act 121 to Act 125 in cooperation with the reading device 27 or the input device 25.

The processor 21 examines the non-target flag 85 included in the record 231R read from the product database 231 (Act126, YES). Here, when the non-target flag 85 is "1", that is, the registration of a product that many customers carry as it is without putting it in my bag, the processor 21 ends the product registration process.

When the non-target flag 85 is “0” (Act126, NO), the processor 21 adds the volume 84 included in the record 231R to the value V of the total volume memory 225 (Act127).
Here, the processor 21 functions as a calculation means by executing the processing of Act 127.

Processor 21 examines the second flag F2 (Act128). The second flag F2 is reset to "0" when the customer does not bring my bag, and is set to "1" when the customer brings my bag. When the second flag F2 is “0” (Act128, NO), the processor 21 sets the value V of the total volume memory 225 as the value D of the register memory 228 (Act129).

When the second flag F2 is “1” (Act128, YES), the processor 21 sets the value obtained by subtracting the value V of the total volume memory 225 from the value C of the capacity memory 227 as the value D of the register memory 228 (Act130). .. Then, the processor 21 confirms whether or not the value D of the register memory 228 is negative (Act131). When the value D of the register memory 228 is 0 or positive, that is, when the total volume V of the registered products is less than or equal to the capacity C of the My Bag (Act131, NO), the processor 21 processes the product registration. To finish.

When the value D of the register memory 228 is negative, that is, when the total volume V of the registered products is larger than the capacity C of the My Bag (Act131, YES), the processor 21 starts from the value V of the total volume memory 225. The value obtained by subtracting the value C of the capacity memory 227 is set as the value D of the register memory 228 (Act132).

When the process of Act129 or Act132 is performed, the processor 21 calculates the required number N of plastic shopping bags. That is, the processor 21 divides the value D of the register memory 228 by the capacity S of the plastic shopping bag, and adds "1" to the integer of the quotient to set the required number of plastic shopping bags N. The processor 21 writes the required number N in the bag number memory 229 (Act133).

The processor 21 causes the display device 26 to display the required number N stored in the bag number memory 229 (Act134). With the above, the processor 21 ends the product registration process.
The required number of plastic shopping bags N is information obtained by comparing the capacity C of the my bag selected from the my bag list on the my bag list selection screen SC6 with the total volume V of the products purchased by the customer. Here, the processor 21 functions as a notification means by executing the processes of Act 130 to Act 134 in cooperation with the display device 26.

In this way, when the registration of the product purchased by the customer is completed, the clerk operates the input device 25 to input the closing of one transaction.
When the processor 21 detects that the closing input of one transaction has been performed via the input device 25, the processor 21 starts information processing of the procedure shown in the flow chart of FIG.

First, the processor 21 examines the third flag F3 in the third flag area 223 (Act 141). Here, when the third flag F3 is reset to "0" (Act141, NO), it is an erroneous operation in which the closing input is performed without registering the product. The processor 21 makes the closing input an error.

When the third flag is set to "1" (Act141), the processor 21 performs the settlement process (Act142). The settlement process is a well-known process such as cash settlement and credit settlement. By this settlement process, the total data of one transaction, payment data, and the like are stored in the transaction memory 224.

When the settlement process is completed, the processor 21 examines the first flag F1 in the first flag area 221 (Act143). The first flag F1 is reset to "0" in the case of a transaction with a customer who does not receive the electronic receipt, and is set to "1" in the case of a transaction with a customer who receives the electronic receipt. When the first flag F1 is reset to "0" (Act143, NO), the processor 21 generates receipt print data based on the contents of the transaction memory 224. Then, the processor 21 outputs the receipt print data to the printer 28 to control the issuance of the paper receipt (Act 144).

When the first flag F1 is set to "1" (Act143, YES), the processor 21 examines the second flag F2 in the second flag area 222 (Act145). The second flag F2 is reset to "0" when the customer does not bring my bag, and is set to "1" when the customer brings my bag. When the second flag F2 is set to "1" (Act 145, YES), the processor 21 acquires the My Bag data stored in the My Bag memory 226 (Act 146). The processor 21 does not acquire my bag data when the second flag F2 is reset to “0” (Act145, NO).

The processor 21 acquires the number of bags N from the number of bags memory 229 (Act 147). Further, the processor 21 generates receipt data from the contents of the transaction memory 224 (Act 148). Then, the processor 21 controls the communication interface 24 and transmits the number of bags and the receipt data to the electronic receipt server 10 together with the receipt member code stored in the work area. The processor 21 also transmits my bag data when the second flag F2 is “1” (Act149).

When the processing of Act 144 or Act 149 is completed, the processor 21 resets the first to third flags F1, F2, and F3 to “0” (Act150). With the above, the processor 21 ends the closing input process.

The electronic receipt server 10 updates the My Bag history 75 of the member database 132 based on the data transmitted from the POS terminal 20. Specifically, the processor 11 of the electronic receipt server 10 acquires the date and the store code from the receipt data received together with the receipt member code. In addition, the number of bags received together with the receipt membership code is acquired. Further, when the My Bag data is received together with the receipt membership code, the My Bag ID included in the My Bag data is acquired. If the My Bag data is not received, the My Bag ID is set to "0". The processor 11 searches the member database 132 and adds the acquired date, store code, my bag ID, and number of bags to the my bag history 75 of the record 132R including the receipt member code.

As described above, in the electronic receipt system 1 of the present embodiment, the electronic receipt server 10 uses the member database 132 to list the my bags owned by the member for each member of the electronic receipt service (my bag ID, identification). Name, capacity) is memorized.

On the other hand, the POS terminal 20 installed in the member store of the electronic receipt service stores information related to the volume of each product by using the product database 231. Then, when the product purchased by the customer is registered via the reading device 27 or the input device 25, the POS terminal 20 calculates the total volume V of the registered product.

Further, the POS terminal 20 identifies a member who uses the information terminal 30 by reading the receipt member code from the information terminal 30 via the reading device 27. Then, when the member is specified, the POS terminal 20 acquires the My Bag list owned by the member from the electronic receipt system 1 and displays it on the display device 26. Here, when any one of the My Bags is selected from the My Bag list by the operation input of the input device 25, the POS terminal 20 stores the capacity C of the My Bag. Then, the POS terminal 20 compares the capacity C of my bag with the total volume V to calculate the required number N of plastic shopping bags, displays it on the display device 26, and notifies the clerk of the required number N, for example. There is.

For example, when the total volume V is equal to or less than the capacity C of the my bag, the product purchased by the member can be stored in the my bag brought by the member, so that 0 is notified as the required number N. When the total volume V exceeds the capacity C of the shopping bag, one is notified as the required number N until the difference value (VC) reaches the capacity S of the shopping bag, and when the difference exceeds the capacity S of the shopping bag, the difference is obtained. Two or more sheets N are notified according to the value (VC). Therefore, the clerk can take appropriate measures such as providing the required number of shopping bags when the purchased products do not fit in the My Bag brought by the member.

Moreover, in the present embodiment, the POS terminal 20 is used so that the member can select the my bag brought by the member from the list of the my bags registered by the member himself / herself. Then, in the POS terminal 20, the capacity of the selected My Bag is compared with the total volume V of the purchased products. Therefore, the member can use any bag or bag as my bag by registering it in the electronic receipt server 10 in advance.

Moreover, in the present embodiment, the My Bag can be registered from the information terminal 30 in which the electronic receipt program 331 is installed. In that case as well, registration can be performed by a simple operation of selecting the corresponding My Bag from a large number of My Bags stored in the My Bag Database 133 in advance. Therefore, for example, even if you notice that the My Bag you brought while shopping at a member store is unregistered, you can immediately register it.

Further, in the present embodiment, it is also possible to delete the My Bag registered in the My Bag list from the information terminal 30. Therefore, for example, when the my bag is disposed of, by deleting the data of the my bag, the disposed my bag will not be displayed in the my bag list forever.

By the way, in the present embodiment, the My Bag history is saved for each member in the member database 132. As described with reference to FIGS. 21 to 23, priorities are set for my bags, and a list of my bags is displayed in descending order of priority. The priority is given to those that are likely to be brought by the members. Therefore, there is a high possibility that the My Bag brought by the member can be easily found from the My Bag list.

Hereinafter, a modified example of the embodiment will be described.
In the above embodiment, the product purchase management device is realized by a system that combines the electronic receipt server 10 and the POS terminal 20. The form of the product purchase management device is not limited to the server and terminal system. A product purchase management device can also be configured by a single computer device.

In the above embodiment, the customer who purchases the product is specified by using the receipt membership code. The information that identifies the customer is not limited to the receipt membership code. For example, a customer may be identified by a point membership code recognized from a point card that can be used in stores of various business formats. In this case, it is assumed that the list storage unit is provided on the server of the company that manages the point card.

In the above embodiment, the My Bag list is displayed in descending order of priority. The My Bag list does not necessarily have to be displayed in descending order of priority. That is, the processing of Act 107 and Act 108 of FIG. 18 may be omitted.

In the above embodiment, the POS terminal 20 is used so that the customer can select the my bag brought by the customer from the my bag list. The terminal used for selecting my bag is not limited to the POS terminal 20. For example, when the "Yes" button B4 is input in Act 7 of FIG. 9 (Act 7, YES), the processor 31 of the information terminal 30 executes the processes of Act 106 to Act 110 of FIG. Then, after the processing of the Act 110, the processor 31 transmits the My Bag ID of the selected My Bag from the information terminal 30 to the electronic receipt server 10. The electronic receipt server 10 stores the My Bag ID of the selected My Bag instead of the bring-in flag. In the determination step of Act105, the processor 21 of the POS terminal 20 determines that the My Bag is brought on the condition that the My Bag ID of the selected My Bag is stored. Then, the processor 21 stores the information of the my bag ID in the my bag memory 226 and the capacity memory 227. With such a configuration, the information terminal 30 can be used to select My Bag.

In the above embodiment, the My Bag list is created from the data of My Bag registered in advance by the customer. Regarding this point, a my bag list may be created from the data of the my bag database 133, and the my bag brought by the customer may be selected from this my bag list. In this case, the customer does not need to pre-register my bag.

In the above embodiment, the required number of shopping bags N is notified by comparing the capacity C of the My bag with the total volume V of the purchased products. The information to be notified is not limited to the required number N of plastic shopping bags. For example, when the total volume V of the purchased products exceeds the capacity C of the my bag, the member may be notified that the product cannot be accommodated in the my bag.

In the above-described embodiment, a bag, a bag, or the like is exemplified as a housing that the customer owns to store the purchased product. In this regard, for example, the trunk of a passenger car, the loading platform of a truck, or the like may be regarded as an accommodation body.

In the above embodiment, the processor 21 of the POS terminal 20 executes the information processing shown by the flow chart of FIGS. 18 to 20 based on the program stored in the main memory 22 or the auxiliary storage device 23 in advance. Such transfer of the POS terminal 20 may be performed in a state where the program is not stored in the main memory 22 or the auxiliary storage device 23. In that case, the program transferred separately from the POS terminal 20 is written to the writable storage device included in the POS terminal 20 according to the operation of the user or the like. The program can be transferred by recording it on a removable recording medium or by communicating via a network. The recording medium may be in any form as long as it can store a program such as a CD-ROM or a memory card and the device can read it. Further, the function obtained by installing or downloading the program may be one that realizes the function in cooperation with the OS (operating system) or the like inside the device.
