That is, when the consumer 4 sets the self-registration system and the electronic receipt system to cooperate, the electronic receipt ID of the consumer 4 and the self-registration ID are associated with each other and stored in the cooperation table 820.

  The electronic receipt server 80 can use, for example, a general-purpose server device or computer device as basic hardware. In the electronic receipt server 80, a server device or a computer device in a state where the electronic receipt server program P4 is not stored in the auxiliary storage device 803 and the electronic receipt server program P4 may be individually transferred to the user. At this time, the transfer of the electronic receipt server program P4 can be realized by recording it on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, a semiconductor memory, or by downloading via a network. In this case, the electronic receipt server program P4 is written in the auxiliary storage device 503 according to the operation by the user.

[Description of product sales processing system operation]
Next, the operation of the merchandise sales processing system when the self-registration system and the electronic receipt system are linked will be described with reference to the flowcharts of FIGS. FIG. 10 is a flowchart showing a main procedure of information processing executed by the processor 401 of the portable information terminal 400 according to the self-registration terminal program P1. FIG. 11 is a flowchart showing a main procedure of information processing executed by the processor 501 of the support server 50 according to the self-registration server program P3. FIG. 12 is a flowchart showing a main procedure of information processing executed when the processor 101 of the POS apparatuses 10 and 20 receives a settlement request command described later according to the control program. FIG. 13 is a flowchart showing a main procedure of information processing executed by the processor 801 of the electronic receipt server 80 in accordance with the electronic receipt server program P4. Note that the contents of the processes illustrated in FIGS. 10 to 13 and described below are merely examples, and various processes capable of obtaining similar results can be used as appropriate.

  The consumer 4 who makes a purchase at the retail store 100 operates the touch panel 404 of the portable information terminal 400 before the purchase to start the self-registration terminal program P1. That is, the consumer 4 touches the icon of the self-registration terminal program P1 displayed on the touch panel 404. When the self-registration terminal program P1 is activated, the processor 401 of the portable information terminal 400 starts the processing shown in the flowchart of FIG.

  First, the processor 401 determines whether or not the support server 50 is logged in (Act 1). If the self-registration terminal program P1 is terminated without logging out when the self-registration terminal program P1 is started last time, the login state is maintained. When the user is logged in, a self-registration ID that is an authentication ID is stored in the self-registration management area W1.

  If not logged in to the support server 50 (NO in Act1), the processor 401 displays a login screen on the touch panel 404 and accepts login (Act2). The consumer 4 logs in by entering his / her self-registration ID on the login screen. The consumer 4 may input a password together with the self registration ID.

  When the login is performed, the processor 401 wirelessly transmits login information including the self-registration ID. This login information is received by the repeater 30 and transmitted to the support server 50 via the LAN 70. The support server 50 performs login authentication. Then, the support server 50 notifies the portable information terminal 400 of the authentication result through a route reverse to the login information.

  The processor 401 determines whether login has been approved (Act 3). If the login is not approved (NO in Act 3), the processor 401 accepts the login again (Act 2). If the login is approved (YES in Act3), the processor 401 stores the self-registration ID used for the login in the self-registration management area W1 (Act4).

  If the login is approved and the self-registration ID is stored in the self-registration management area W1 or if the login is in progress and the self-registration ID is stored in the self-registration management area W1 (YES in Act1), the processor 401 The self registration ID is detected from the self registration management area W1. Further, the processor 401 detects the cooperation flag F from the self-registration management area W1 (Act5). The cooperation flag F is set to “1” when the consumer sets the self-registration system and the electronic receipt system to cooperate. When the setting for cooperation is not performed, the cooperation flag F is reset to “0”.

  The processor 401 wirelessly transmits a registration start declaration command including the self registration ID detected from the self registration management area W1 and the information indicated by the cooperation flag F (Act 6). The registration start declaration command transmitted from the wireless unit 406 is received by the repeater 30 and transmitted to the support server 50 via the LAN 70.

  The processor 501 of the support server 50 in which the self-registration server program P3 resides waits for a registration start declaration command as shown in FIG. 11 (Act 21). When the registration start declaration command transmitted from the portable information terminal 400 is received, the processor 501 acquires store information from the store information area W3 of the auxiliary storage device 503 (Act22). Further, the processor 501 creates a product transaction file 510 in the transaction file area W4. The processor 501 stores the information indicated by the self-registration ID and the linkage flag F included in the registration start declaration command and the store information acquired from the store information area W3 in the commodity transaction file 510 (Act23).

  The processor 501 transmits the store information to the portable information terminal 400 that is the transmission source of the registration start declaration command (Act 24). The store information is wirelessly transmitted from the repeater 30 and received by the wireless unit 406 of the portable information terminal 400 that has transmitted the registration start declaration command. Note that the processing procedure of Act22 and Act23 is not limited to the above procedure. The front and back may be reversed. Moreover, the processing procedure of Act23 and Act24 is not limited to said procedure. The front and back may be reversed.

  As shown in FIG. 10, the processor 401 of the portable information terminal 400 that has transmitted the registration start declaration command waits for store information (Act 7). When store information is received by wireless unit 406 (YES in Act 7), processor 401 displays a registration screen on touch panel 404 (Act 8). The processor 401 drives the camera unit 405 (Act 9). Note that the processing procedure of Act8 and Act9 is not limited to the above procedure. The front and back may be reversed.

  For example, store information is displayed on the registration screen. In addition, a detail column for displaying the product name, price, total amount, etc. is formed on the registration screen. A message prompting the consumer 4 to self-register may be displayed on the registration screen. The consumer 4 confirming the registration screen starts shopping at the sales floor 6. Then, the consumer 4 images the barcode of the purchased product 5 with the camera unit 405. The imaged product 5 is put in a cart or the like.

  The processor 401 of the portable information terminal 400 waits for a barcode to be detected from the image captured by the camera unit 405 (Act 10). When the barcode is detected (YES in Act 10), the processor 401 adds the self-registration ID stored in the self-registration management area W1 to the barcode data and wirelessly transmits it (Act 11). The barcode data with the self-registration ID transmitted from the wireless unit 406 is received by the repeater 30 and transmitted to the support server 50 via the LAN 70.

  As shown in FIG. 11, the processor 501 of the support server 50 that has transmitted the store information to the portable information terminal 400 waits for barcode data from the portable information terminal 400 (Act 25). When the barcode data with the self-registration ID is received (YES in Act 25), the processor 501 determines whether the barcode data is a product code or a POSID (Act 26, 27). The barcode 7 representing the POSID and the barcode representing the product code have different code systems. The processor 501 determines the type of barcode based on the difference in the code system.

  When the barcode data is a product code (YES in Act 26: product detection means), the processor 501 accesses the store server 40. Then, the processor 501 acquires product data (product name, price, etc.) associated with the product code from the product database 41 included in the store server 40 (Act 28).

When the product data is acquired, the processor 501 creates product sales data including a product code, a product name, a unit price, a sales score, a sales price, and the like based on the product data (Act 29). The processor 501 registers the product sales data in the product transaction file 510 specified by the self-registration ID added to the barcode data (Act30: storage unit). The processor 501 transmits the product sales data to the portable information terminal 400 that is the transmission source of the barcode data (Act 31). The merchandise sales data is wirelessly transmitted from the repeater 30 and received by the wireless unit 406 of the portable information terminal 400 that transmitted the barcode data. In addition, the processing procedure of Act30 and Act31 is not limited to said procedure. The front and back may be reversed.
The processor 501 that has finished the processing of Act30 and Act31 waits for the next barcode data to be sent from the same portable information terminal 400 (Act25).

  As shown in FIG. 10, the processor 401 of the portable information terminal 400 that has transmitted the barcode data waits for data from the support server 50 (Act 12). When data is received from support server 50 (YES in Act 12), processor 401 determines whether or not the data is merchandise sales data (Act 13). In the case of product sales data (YES in Act 13), the processor 401 displays the product name, price, etc. of the sales product included in the product sales data in the detail column of the registration screen (Act 14). Thereafter, the processor 401 waits until the next barcode is detected from the image captured by the camera unit 405 (Act 10).

  Thus, whenever the consumer 4 images the barcode of the sales commodity 5 with the camera unit 405, the processor 401 of the portable information terminal 400 executes the processes of Act10 to Act14. On the other hand, the support server 50 executes the processes of Act25 to Act31. As a result, a merchandise transaction file 510 in which the self-registration ID of the consumer 4 is stored in the transaction file area W4 of the support server 50 is formed. Then, store information and linkage flag F are stored in the product transaction file 510, and sales data (product data) of the product 5 purchased by the consumer 4 is accumulated.

  The consumer 4 who has finished shopping at the sales floor 6 goes to the accounting floor 1 and performs accounting. Accounting may be performed by the checkout counter 2 or by the self-type POS device 20. When accounting is performed by the checkout counter 2, the consumer 4 images the barcode 7 written on the scanner 11 on the checkout counter 2 with the camera unit 405. When accounting is performed by the self-type POS device 20, the consumer 4 images the barcode 7 written on the housing of the POS device 20 with the camera unit 405.

  Even when the consumer 4 images the barcode 7 with the camera unit 405, the processor 401 of the portable information terminal 400 operates in the same manner as when the consumer 4 images the barcode of the product 5. That is, when a bar code is detected from an image captured by camera unit 405 (YES in Act 10), processor 401 adds the self registration ID stored in self registration management area W1 to the bar code data. Wirelessly transmitted (Act11). The barcode data with the self-registration ID transmitted from the wireless unit 406 is received by the repeater 30 and transmitted to the support server 50 via the LAN 70.

  On the other hand, when the processor 501 of the support server 50 receives the barcode data with the self-registration ID (YES in Act 25), the processor 501 determines whether the data is a barcode representing a product code or a barcode 7 representing a POSID. (Act 26, 27). In the case of the bar code 7 representing the POSID (YES in Act 27: payment unit detection means), the processor 501 refers to the POS device 10 or 20 to which the POSID is set as a payment target POS device (hereinafter referred to as a payment POS device). ) (Act 32).

  For example, the processor 501 makes a POSID inquiry to each POS device 10 or 20 connected via the LAN 70. Then, the processor 501 identifies the POS device 10 or 20 that has responded with the POSID detected from the barcode data as a settlement POS device. If the settlement POS device 10 or 20 is specified, the processor 501 transmits a settlement request command to the settlement POS device 10 or 20 (Act 33). The payment request command is transmitted to the payment POS device 10 or 20 via the LAN 70.

  Upon receiving the payment request command, the processor 101 of the payment POS apparatuses 10 and 20 executes information processing according to the procedure shown in the flowchart of FIG. That is, the processor 101 determines whether or not the commercial transaction is ongoing (Act 41).

  In the case of the self-type POS device 20, the commercial transaction with the previous consumer 4 is completed when the consumer 4 captures the barcode 7 with the camera unit 405 of the portable information terminal 400. However, in the case of the face-to-face POS device 10, the commercial transaction with the previous consumer 4 may not be completed. If the commercial transaction has not ended, the processor 101 recognizes that the commercial transaction is ongoing. In this case (YES in Act 41), processor 101 waits for the end of the commercial transaction. If the commercial transaction with the previous consumer has ended or has ended (NO in Act 41), the processor 101 returns a permission response to the support server 50 (Act 42).

  As shown in FIG. 11, the processor 501 of the support server 50 that has transmitted the payment request command to the payment POS apparatus 10 or 20 waits for a permission response (Act 34). When a permission response is received from settlement POS device 10 or 20 (YES in Act 34), processor 501 detects commodity transaction file 510 specified by the self-registration ID added to the barcode data. Then, the processor 501 transmits the data of the commodity transaction file 510 to the settlement POS apparatus 10 or 20 (Act35: first transmission means).

  As shown in FIG. 12, the processor 101 of the settlement POS apparatus 10 or 20 that has transmitted the permission response to the support server 50 waits for the commodity transaction file 510 (Act 43). If data of merchandise transaction file 510 is received from support server 50 via communication interface 504 (YES in Act 43), processor 101 uses merchandise sales data included in merchandise transaction file 510 as a transaction in main memory 102. Expand into the area. Then, the processor 101 displays the product name, price, etc. constituting the product sales data developed in this transaction area on the display 13a or the touch panel 22 (Act44).

  The processor 101 waits for payment data to be input (Act 45). When the barcode of the product is read via the scanners 11 and 21 while waiting for the payment data to be input, the processor 101 identifies the product from the barcode and uses the sales data of the product as a transaction. Add to the area.

  When payment data is input via keyboard 12 or touch panel 22 (YES in Act 45), processor 101 performs payment processing for the merchandise sales data stored in the transaction area based on the payment data (payment means). ). In this settlement process, the processor 101 creates print data of receipt data (Act 46: generation means).

  When the settlement process is completed, the processor 101 checks the cooperation flag F included in the product transaction file 510 sent from the support server 50 (Act 47). Here, when the cooperation flag F is set to “1”, the consumer 4 who has performed self-registration performs a setting for linking the self-registration system and the electronic receipt system. If the setting for cooperation is performed (YES in Act 47), the processor 101 creates electronic receipt data obtained by digitizing the receipt data (Act 48). The processor 101 displays a screen for inquiring whether or not to issue a receipt on paper on the display 13a or the touch panel 22. Then, the processor 101 waits for an input as to whether or not to issue a receipt in paper (Act 49: accepting means).

  Here, when an input to the effect that the receipt is not issued in paper is received by the operation of the keyboard 12 or the touch panel 22 (NO in Act 49), the processor 101 includes the self-registration ID included in the commodity transaction file 510 in the electronic receipt data. Is attached. Then, the processor 101 transmits the electronic receipt data to which the self-registration ID is attached to the electronic receipt server 80 (Act 50: second transmission means).

  On the other hand, when receiving an input to issue a receipt as paper by operating the keyboard 12 or the touch panel 22 (YES in Act 49), the processor 101 drives the printers 14 and 24 to issue a paper receipt. (Act51: Control means). Further, even when the cooperation flag F included in the commodity transaction file 510 is reset to “0” (NO in Act 47), the processor 101 controls the issuance of a paper receipt (Act 51).

  When the electronic receipt data is transmitted to the electronic receipt server 80 or the paper receipt issuance is controlled in this way, the processor 101 transmits a settlement end command to the support server 50 (Act 52). Thus, the processor 101 ends the information processing when the payment request command is received.

  As shown in FIG. 11, the processor 501 of the support server 50 that has transmitted the data of the commodity transaction file 510 to the payment POS device 10 or 20 waits for a payment end command (Act 36). When the settlement end command is received from settlement POS device 10 or 20 (YES in Act 36), processor 501 wirelessly transmits the settlement end command to portable information terminal 400 that transmitted the barcode data of POSID (Act 37). . Further, the processor 501 deletes the commodity transaction file 510 that has transmitted data to the settlement POS apparatus 10 or 20 from the transaction file area W4 (Act38). Thus, the processor 501 ends the information processing after receiving the registration start declaration command. Note that the processing procedure of Act 37 and Act 38 is not limited to the above procedure. The front and back may be reversed. Further, the commodity transaction file 510 deleted from the transaction file area W4 may be stored in another area formed in the auxiliary storage device 503.

  As shown in FIG. 10, the processor 401 of the portable information terminal 400 that has transmitted the barcode data waits for data from the support server 50 (Act 12). When data is received from support server 50 (YES in Act 12), processor 401 determines whether or not the data is merchandise sales data (Act 13). If it is not commodity sales data (NO in Act 13), the processor 401 determines whether or not the data is an end command (Act 15). In the case of an end command (YES in Act 15), the processor 401 deletes the registration screen displayed on the touch panel 404 (Act 16). Thus, the processor 401 ends the information processing according to the self-registration terminal program P1.

  The processor 801 of the electronic receipt server 80 waits for data as shown in FIG. 13 (Act 61). When data is received via network 200 (YES in Act 61), processor 801 confirms whether the data is electronic receipt data (Act 62). When electronic receipt data is received (YES in Act 62), the processor 801 determines whether the ID added to the data is a self-registration ID or an electronic receipt ID (Act 63).

  When the electronic receipt ID is added to the electronic receipt data (NO in Act 63), the processor 801 creates an electronic receipt file 810 including the electronic receipt ID and the electronic receipt data, and stores it in the electronic receipt area W5. (Act65).

  When the self-registration ID is added to the electronic receipt data (YES in Act 63), the processor 801 searches the linkage table 820. The processor 801 detects the electronic receipt ID set in the cooperation table 820 in association with the self-registration ID (detection unit). Then, the processor 801 converts the self-registration ID into an electronic receipt ID detected from the cooperation table 820 (Act 64). After converting the self-registration ID into the electronic receipt ID, the processor 801 creates an electronic receipt file 810 including the converted electronic receipt ID and electronic receipt data, and stores it in the electronic receipt area W5 (Act65: storage means). . Thus, the processor 801 ends the information processing when receiving electronic receipt data.

  Thus, the electronic receipt data of the commercial transaction in which the sales merchandise is registered by self-registration is added to the self-registration ID of the consumer 4 who performed the self-registration and is transmitted to the electronic receipt server 80. When the self-registration ID is added to the electronic receipt data, the electronic receipt server 80 converts the self-registration ID into the electronic receipt ID of the consumer 4. Then, the electronic receipt server 80 creates an electronic receipt file 810 including the electronic receipt ID and stores it in the electronic receipt area W5. On the other hand, when the electronic receipt data to which the electronic receipt ID is added instead of the self-registration ID is received, the electronic receipt server 80 creates an electronic receipt file 810 including the electronic receipt ID and stores it in the electronic receipt area W5. save.

  The electronic receipt ID is an authentication ID when the consumer 4 who is an electronic receipt member logs in to the electronic receipt server 80 from the portable information terminal 400. Accordingly, the consumer 4 who has performed self-registration using the portable information terminal 400 can view the electronic receipt of the commercial transaction in which the merchandise is registered by the self-registration using the portable information terminal 400.

  The device that can log in to the electronic receipt server 80 with the electronic receipt ID is not limited to the portable information terminal 400. It is also possible to log in from the information processing apparatus 210 such as a personal computer. Therefore, an electronic receipt of a commercial transaction in which a product for sale is registered by self-registration can also be viewed from the information processing apparatus 210 such as a personal computer.

In addition, the consumer 4 or the cashier 3 does not need to input the electronic receipt ID to the POS devices 10 and 20 at the time of settlement of the commercial transaction in which the sales merchandise is registered by self-registration. Therefore, the effort of the consumer 4 and the cashier 3 is not increased by linking the self-registration system and the electronic receipt system.
As described above, according to the present embodiment, the merchandise registration operation by the cashier can be simplified by adopting the self-registration system, and not only the time required for settlement processing is shortened, but also the time required for issuing the paper receipt by adopting the electronic receipt system. Therefore, the processing capacity of the accounting office 1 can be greatly increased. As a result, it is possible to alleviate congestion at the accounting place 1. In addition, the consumer 4 does not need to present the electronic receipt ID at the accounting office in order to receive the electronic receipt.
In the first embodiment, the POS device 10 or 20 creates electronic receipt data and transmits it to the electronic receipt server 80. However, the store server 40 or the support server 50 creates electronic receipt data, and the electronic receipt server You may send to 80 address.
In the case of the store server 40, the POS device 10 or 20 transmits product sales data and payment data necessary for creating an electronic receipt to the store server 40. On the other hand, in the case of the support server 50, since the product sales data is stored in the product transaction file 510, the POS device 10 or 20 need only transmit the payment data together with the self-registration ID to the support server 50.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. In FIG. 14 to FIG. 16, the same reference numerals are given to portions common to the first embodiment, and detailed description thereof is omitted.

  FIG. 14 is a block diagram showing a main configuration of the portable information terminal 400-2 in the second embodiment. The difference between the portable information terminal 400-2 and the portable information terminal 400 of the first embodiment is data stored in the self-registration management area W1 of the auxiliary storage device 403. That is, the portable information terminal 400-2 stores the electronic receipt ID in the self registration management area W1.

  Also in the second embodiment, as in the first embodiment, the consumer 4 arbitrarily sets whether or not to link the self-registration system and the electronic receipt system. When the setting for linking the self-registration system and the electronic receipt system is made, the processor 401 of the portable information terminal 400 sets the linking flag F in the self-registration management area W1. Further, the processor 401 stores an electronic receipt ID, which is an authentication ID when the consumer 4 logs into the electronic receipt server 80, in the self-registration management area W1.

  The electronic receipt ID is stored in the electronic receipt management area W2 by logging into the electronic receipt server 80. Therefore, when setting for linking the self-registration system and the electronic receipt system, the consumer 4 logs in the electronic receipt server 80 by starting the electronic receipt terminal program P2. Then, since the electronic receipt ID is stored in the electronic receipt management area W2, the processor 401 copies the electronic receipt ID in the electronic receipt management area W2 to the self-registration management area W1. Further, the processor 401 sets the cooperation flag F. The electronic receipt ID is not deleted even if the electronic receipt server 80 logs out. Similarly, the linkage flag F is not reset even if the user logs out from the electronic receipt server 80. Thus, when the setting for linking the self-registration system and the electronic receipt system is made, the self-registration management area W1 stores the electronic receipt ID and the linkage flag F is set. On the other hand, when canceling the cooperation between the self-registration system and the electronic receipt system, the consumer 4 activates the self-registration terminal program P1 and performs a predetermined setting cancellation operation. By doing so, the electronic receipt ID is deleted from the self-registration management area W1. Also, the cooperation flag F is reset.

  FIG. 15 is a schematic diagram showing a data structure of a commodity transaction file 510-2 stored in the transaction file area W4 of the support server 50 in the second embodiment. The product transaction file 510-2 in the second embodiment is different from the product transaction file 510 in the first embodiment in the number of IDs to be stored. The product transaction file 510 of the first embodiment stores only the self-registration ID. The merchandise transaction file 510-2 of the second embodiment stores an electronic receipt ID in addition to the self-registration ID.

  FIG. 16 is a flowchart showing a part of information processing executed by the processor 401 of the portable information terminal 400 according to the self-registration terminal program P1 in the second embodiment. As shown in FIG. 16, in the second embodiment, the processes of Act 71 and Act 72 are performed between the detection process of the Act 5 self-registration ID and the linkage flag F and the process of transmitting the registration start declaration command of Act 6. to add.

  That is, after finishing the process of Act5, the processor 401 proceeds to the process of Act71. In Act 71, the processor 401 determines whether or not the cooperation flag F is detected from the self-registration management area W1. When the portable information terminal 400 is not set to link the self-registration system and the electronic receipt system, the linkage flag F is not detected. In this case, the processor 401 determines “NO” in Act 71, and proceeds to the process of Act 6. That is, the processor 401 wirelessly transmits a registration start declaration command including the self registration ID acquired from the self registration management area W1 and the information indicated by the cooperation flag F.

  On the other hand, when the portable information terminal 400 is set to link the self-registration system and the electronic receipt system, the linkage flag F is detected. In this case, the processor 401 determines “YES” in Act 71, and proceeds to the processing of Act 72.

  In Act 72, the processor 401 detects the electronic receipt ID from the self-registration management area W1. After detecting the electronic receipt ID, the processor 401 proceeds to the process of Act6. That is, the processor 401 wirelessly transmits a registration start declaration command including the self-registration ID and electronic receipt ID acquired from the self-registration management area W1 and the information indicated by the cooperation flag F. The processing after Act 6 is the same as that in the first embodiment.

  The support server 50 that has received the registration start declaration command executes information processing according to the procedure shown in the flowchart of FIG. 11 as in the first embodiment. However, in the second embodiment, a part of the processing of Act 23 is different from the first embodiment. In other words, in the first embodiment, the processor 501 determines, as Act 23, the product transaction file 510 from the information indicated by the self-registration ID and the linkage flag F included in the received registration start declaration command and the store information acquired in the processing of Act 22. It was created. Also in the second embodiment, when the information included in the registration start declaration command is only the information indicated by the self-registration ID and the cooperation flag F, the processor 501 creates the commodity transaction file 510 as Act23.

  However, as described with reference to FIG. 16, the registration start declaration command may include an electronic receipt ID in addition to the self-registration ID and the information indicated by the cooperation flag F. In that case, the processor 501 creates a commodity transaction file 510-2 as Act23. That is, the processor 501 creates a product transaction file 510 from the self-registration ID and electronic receipt ID included in the received registration start declaration command, the information indicated by the cooperation flag F, and the store information acquired in the processing of Act22 (accumulation). means).

  In addition, the processor 101 of the POS devices 10 and 20 that has received the settlement request command executes information processing according to the procedure shown in the flowchart of FIG. 12, as in the first embodiment. However, in Act 50, the processor 101 attaches the electronic receipt ID included in the commodity transaction file 510-2 to the electronic receipt data. No self registration ID is attached. The processor 101 transmits the electronic receipt data to which the electronic receipt ID is attached to the electronic receipt server 80 (second transmission means).

  The processor 801 of the electronic receipt server 80 that has received the electronic receipt data executes information processing according to the procedure shown in the flowchart of FIG. 13 as in the first embodiment. However, since the ID attached to the electronic receipt data is an electronic receipt ID, it is always determined as “NO” in the process of Act 63. Therefore, the process of Act64 is not executed. That is, in the second embodiment, the linkage table 820 included in the electronic receipt server 80 is not necessary.

[Third Embodiment]
Next, a third embodiment will be described with reference to FIGS. In FIG. 17 and FIG. 18, the same reference numerals are given to the portions common to the first embodiment, and detailed description thereof will be omitted.

  FIG. 17 is a block diagram showing a main configuration of the POS devices 10-3 and 20-3 in the third embodiment. The point that the POS apparatuses 10-3 and 20-3 are different from the POS apparatuses 10 and 20 is that the cooperation table area W7 is formed in the auxiliary storage device 103. This linkage table area W7 is an area for storing the linkage table 820 having the data structure shown in FIG.

  In the first embodiment, the electronic receipt server 80 includes the linkage table 820. In the third embodiment, the POS devices 10-3 and 20-3 include a linkage table 820. The electronic receipt server 80 does not include the linkage table 820.

  FIG. 18 is a flowchart showing a main procedure of information processing executed when the processor 101 of the POS apparatuses 10 and 20 receives a payment request command to be described later according to the control program. The information processing procedure (see FIG. 10) executed by the processor 401 of the portable information terminal 400 according to the self-registration terminal program P1 and the information processing procedure executed by the processor 501 of the support server 50 according to the self-registration server program P3 (see FIG. 10). 11) is the same as that of the first embodiment, and the description thereof is omitted here.

  As shown in FIG. 18, in the third embodiment, when it is determined as “YES” in the determination process of Act 47, the process proceeds to the process of Act 48 after performing the process of Act 81. And different.

  That is, when the cooperation flag F included in the commodity transaction file 510 sent from the support server 50 is checked and set to “1” (YES in Act 47), the processor 101 searches the cooperation table 820. To do. Then, the processor 101 detects the electronic receipt ID that is associated with the self-registration ID and set in the cooperation table 820 (detection unit). Then, the processor 101 converts the self-registration ID into an electronic receipt ID detected from the cooperation table 820 (Act81). After that, the processor 101 digitizes the receipt data and creates an electronic receipt (Act48). Note that the processing procedure of Act 81 and Act 48 is not limited to the above procedure. The front and back may be reversed.

  As described above, in the third embodiment, the POS devices 10-3 and 20-3 include the linkage table 820. When the cooperation flag F included in the commodity transaction file 510 sent from the support server 50 is set to “1”, the POS apparatuses 10-3 and 20-3 use the self-registration ID as an electronic receipt ID. Convert to Then, the POS devices 10-3 and 20-3 attach the electronic receipt ID to the electronic receipt created based on the merchandise sales data stored in the merchandise transaction file 510 and transmit it to the electronic receipt server 80.

Therefore, also in the third embodiment, it is possible to cope with both functions of the self-registration system and the electronic receipt system without increasing the labor of the consumer 4 and the cashier 3. Therefore, similarly to the first embodiment, the processing capacity of the accounting place 1 can be greatly increased, and congestion can be reduced. Further, the consumer 4 set to receive the electronic receipt does not feel bothersome at the accounting place 1.
In addition, since an electronic receipt with an electronic receipt ID is transmitted to the electronic receipt server 80, the existing electronic receipt server 80 can be used as it is as in the second embodiment.
In the third embodiment, the POS device 10 or 20 creates electronic receipt data and transmits it to the electronic receipt server 80. However, the store server 40 or the self-registration support server 50 creates electronic receipt data, It may be transmitted to the receipt server 80. In this case, it is also possible for the store server 40 or the support server 50 to include the linkage table 820.
When the support server 50 includes the linkage table 820, the self-registration ID is stored in the product transaction file 510. For this reason, the processor 501 of the support server 50 only needs to detect the electronic receipt ID set in the cooperation table 820 in association with the self-registration ID of the commodity transaction file 510.

  The present invention is not limited to the above embodiment.

  For example, in the above-described embodiment, the consumer 4 can arbitrarily set whether or not to link the self-registration system and the electronic receipt system. In another embodiment, cooperation between the self-registration system and the electronic receipt system can be considered essential. In this case, the cooperation flag F is not necessary. Further, the processing of Act 47 in FIG. 12 is omitted from the processor 101 of the POS devices 10 and 20. In the embodiment, the consumer 4 can select whether the receipt is received as a paper receipt or an electronic receipt. In another embodiment, it is conceivable that paper receipts are eliminated and all receipts are electronic receipts. In this case, the processing of Acts 47, 49 and 51 in FIG. 12 is omitted.

  From the above viewpoint, the second transmission means is configured such that when the self-registration ID is associated with the merchandise sales data (product data) of the transaction to be settled, that is, the merchandise data is input by self-registration by the portable information terminal 400. If it is a thing, what is necessary is just the means which attaches the said self-registration ID to an electronic receipt, and transmits to the electronic receipt server 80.

  Further, in the above embodiment, the self-registration performed by the consumer 4 himself / herself for inputting the product data by the portable information terminal 400 is exemplified, but the present invention is not necessarily limited to self-registration. For example, a store clerk may accompany the consumer 4, and the store clerk may operate the portable information terminal 400 to input data of products purchased by the consumer.

  Further, in the above-described embodiment, the consumer 4 has photographed the barcode 7 attached to the POS devices 10 and 20 with the camera unit 405 in order to identify the POS devices 10 and 20 to be settled. If the portable information terminal 400 has an NFC (Near Field Communication) reader, an NFC tag is attached to the POS devices 10 and 20 instead of the barcode 7, and the NFC reader reads the POSID from the NFC tag. The POS devices 10 and 20 to be settled may be specified.

  In the first embodiment, in the Act 64 process of the information processing procedure executed by the processor 801 of the electronic receipt server 80, the self-registration ID is converted into the electronic receipt ID with reference to the linkage table 820. This process does not necessarily convert the ID. The processor 801 may only extract the electronic receipt ID that is associated with the self-registration ID and set in the cooperation table 820. That is, in the processing of Act 65, the processor 801 may create an electronic receipt file 810 including the extracted electronic receipt ID and electronic receipt data, and store the electronic receipt file 810 in the electronic receipt area W5.

  Similarly, in the third embodiment, in the Act 81 process of the information processing procedure executed by the processor 101 of the POS devices 10 and 20, the self-registration ID is converted into the electronic receipt ID with reference to the linkage table 820. Also regarding this processing, the processor 101 extracts the electronic receipt ID set in the cooperation table 820 in association with the self-registration ID. In the process of Act 50, the processor 101 may attach the extracted electronic receipt ID to the electronic receipt data and transmit it to the electronic receipt server 80.

  In the embodiment, the store server 40 and the support server 50 are provided in the retail store 100. About this point, it is also possible to have the functions of the store server 40 and the support server 50 in one server. The support server 50 is installed outside the retail store 100. And the merchandise sales processing system of each retail store 100 may share the support server 50 via the network 200. Further, the portable information terminal 400 may not necessarily be carried by the consumer 4. For example, an information terminal attached to a shopping cart may be used instead of the portable information terminal 400.

In addition, some embodiments of the present invention have been described. However, these embodiments are presented as examples, and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
