Description

Embodiments of the present invention relate to a checkout system, a product registration device and its control program, and a payment device and its control program.

It was decided that the purchase registration and settlement processes in supermarkets, etc. would be performed by different product registration devices and payment devices, and that the employees would operate the product registration devices and the shoppers would operate the payment devices. A semi-self-type checkout system is known.
In such a system, the payment information for payment processing is transferred from the product registration device to the payment device in the vacant state. If the same payment device has a plurality of payment information, there is a risk of confusion among shoppers who try to make a payment. Therefore, the payment device that has received one payment information is prevented from receiving new payment information until the payment based on the payment information is completed.

By the way, a shopper may wish to settle a plurality of products brought to the checkout corner of a store for purchase by dividing them into a plurality of accounts. Such an accounting form will be referred to as "split accounting" in the present specification.
When performing split accounting, the product registration device generates settlement information for each of a plurality of accounts. These plurality of payment information will be transferred to different payment devices, and the shopper must operate each of the plurality of payment devices to make a payment.

If you wait for the settlement of one accounting to be completed and transfer the settlement information of another accounting to the settlement device used for the settlement, the shopper can use one accounting device for multiple accounting. It becomes possible to make a payment. However, in this case, there is a possibility that the processing efficiency of the product registration device may be lowered due to the waiting time for transferring the payment information in the product registration device.
Under these circumstances, it is hoped that payments based on multiple payment information related to split accounting can be performed on the same payment device without increasing the waiting time for transferring payment information on the product registration device. It was rare.

Japanese Unexamined Patent Publication No. 2006-344123

The problem to be solved by the present invention is a checkout in which payment based on a plurality of payment information related to split accounting can be performed in the same payment device without increasing the waiting time for transferring the payment information in the product registration device. It is to provide a system, a product registration device and its control program, and a payment device and its control program.

The checkout system of the embodiment includes a product registration device and a payment device, and the product registration device includes a creation unit, a generation unit, a notification unit, a determination unit, a first control unit, a storage unit, and a second control unit. The payment device includes a payment unit and a issuing unit. The creation department acquires the product code of the purchased product and creates a list of the purchased products. The generation unit generates payment information for payment of the purchased product based on the list created by the creation unit. The notification unit notifies one of the payment devices of the payment information generated by the generation unit. The deciding unit decides the implementation of the split accounting that divides the accounting for the purchased products of the same shopper into a plurality of times according to the instruction by the operator. If the decision unit has not decided to implement the split accounting, the first control unit prohibits the start of new creation of the list until the notification unit notifies the settlement information, and the split accounting is executed. If it is determined, the creation unit is controlled so as to allow the start of new creation of the list even if the notification unit has not notified the payment information. The storage unit stores payment information that has not been notified by the notification unit. The second control unit controls the notification unit so as to notify one of the payment devices of all the payment information stored in the storage unit in response to the instruction of the payment information notification by the operator. .. The settlement unit performs payment processing based on the payment information notified by the notification unit. When a plurality of payment information is notified by the notification unit, the issuing unit individually issues a receipt based on each of the plurality of payment information.

As the hardware of the payment device 12, for example, an existing self-POS terminal can be used.

Next, the operation of the checkout system 10 configured as described above will be described.
The content of the process described below is an example, and various processes capable of obtaining similar results can be appropriately used.
When the product registration device 11 is started in the mode for registering the purchased product, the CPU 11a starts the control process according to the control program stored in the ROM 11b or the auxiliary storage unit 11d.

3 and 4 are flowcharts of the control process of the CPU 11a.
In Act1, the CPU 11a resets the division flag. The split flag indicates that the split accounting is set when the set state is set. The division flag is realized as, for example, 1-bit data in the RAM 11c.

In Act2, the CPU 11a clears the registered product table set in the RAM 11c. The registered product table is a data table for describing information about products for which purchase registration has been completed.
In Act3, the CPU 11a uses a part of the screen of the touch panel 11g as a standby screen.

FIG. 5 is a diagram showing a standby screen SC1 as an example.
The standby screen SC1 includes texts T1 and T2 and button B21.
The text T1 indicates that the employee 21 should start the operation for registering the purchased product. The text T2 indicates that the employee 21 should touch the button B21 prior to starting the operation for registering the purchased product when performing the split accounting.

In Act 4, the CPU 11a confirms whether or not the execution of the split accounting is instructed. Then, if the CPU 11a determines No because the operation for the corresponding instruction has not been performed, the CPU 11a proceeds to Act5.
In Act5, the CPU 11a confirms whether or not the product code of the product to be registered for purchase has been acquired. Then, if the CPU 11a determines No because the product code has not been acquired, the CPU 11a returns to Act4.
Thus, in Act4 and Act5, the CPU 11a waits for the execution of the split accounting or the acquisition of the product code. The CPU 11a may confirm the occurrence of another event such as another operation being performed in the standby here, and may shift to the processing according to the occurrence event.

When the shopper requests the split accounting, the employee 21 instructs the execution of the split accounting by an operation such as touching the button B21. Then, if such an operation is detected by, for example, the touch panel 11g, the CPU 11a determines Yes in Act4 and proceeds to Act6.

In Act6, the CPU 11a sets the division flag.
Thus, when the CPU 11a executes the above control process based on the control program, the computer and the touch panel having the CPU 11a as the central portion function as a determination unit.
In Act7, the CPU 11a sets "1" as the value of the variable m. The variable m represents the number of settlements. Then, the CPU 11a proceeds to Act9 after this.

By the way, the CPU 11a acquires the product code based on the operation by the employee 21 by a well-known process different from the control process shown in FIGS. 3 and 4. Then, when the CPU 11a acquires the product code, the CPU 11a determines Yes in Act5 and proceeds to Act8.
In Act8, the CPU 11a updates the registered product table so as to include the acquired product code. Then, the CPU 11a proceeds to Act9 after this. Thus, the CPU 11a keeps the split flag in the reset state if the operation for purchase registration is performed without being instructed to carry out the split accounting.

In Act9, the CPU 1a uses a part of the screen of the touch panel 11g as a registration screen. The registration screen shows the contents of the registered product table and the like, and causes the employee 21 to confirm the implementation status of the registration process.

FIG. 6 is a diagram showing a registration screen SC2 as an example.
The registration screen SC2 includes areas R1 and R2.
The area R1 is an area for displaying the product name, quantity, and unit price of the most recently registered product, and the total quantity and total price of the purchased products after the product is registered. The area R2 is an area for displaying a list of product names, quantities, unit prices, and amounts related to products for which purchase registration has been made prior to the products shown on the registration screen SC2.

The registration screen SC2 shows a state in which various information regarding the product for which purchase registration has been made is displayed. However, if the CPU 11a progresses from Act7 to Act9, the registered merchandise table does not include information about purchased merchandise. For this reason, the registration screen does not represent various information about the product, but only the predetermined basic form. Further, when the CPU 11a advances from Act 8 to Act 9, the registered product table contains only information about one product. Therefore, the registration screen represents information about the product in the area R2, but does not display information about the product in the area R1.

Further, the CPU 11a displays various function buttons such as a product button for the employee 21 to specify a product and a subtotal button in addition to the area designated as the registration screen in the screen of the touch panel 11g. Is omitted.

In Act10 in FIG. 3, the CPU 11a confirms whether or not the subtotal button displayed on the screen of the touch panel 11g is touched. Then, if the CPU 11a determines No because the touch panel 11g has not detected that the subtotal button has been touched, the CPU 11a proceeds to Act 11.
In Act 11, the CPU 11a confirms whether or not the product code of the product to be registered for purchase has been acquired. Then, if the CPU 11a determines No because the product code has not been acquired, the CPU 11a returns to Act10.
Thus, in Act10 and Act11, the CPU 11a waits for the subtotal button to be touched or the product code to be acquired. The CPU 11a may confirm the occurrence of another event such as another operation being performed in the standby here, and may shift to the processing according to the occurrence event.

When the CPU 11a acquires the product code, the CPU 11a determines Yes in Act 11 and proceeds to Act 12.
In Act 12, the CPU 11a updates the registered product table so as to include the acquired product code. In response to this, the CPU 11a updates the registration screen so as to conform to the contents of the updated registered product table. Then, the CPU 11a returns to the standby state of Act10 and Act11 after this. Thus, when the CPU 11a executes the control process based on the control program, the computer having the CPU 11a as the central part functions as a creating unit.

If the touch panel 11g detects that the subtotal button has been touched, the CPU 11a determines Yes in Act10 and proceeds to Act13 in FIG.
In Act13, the CPU 11a confirms whether or not the division flag is set. Then, if the CPU 11a determines Yes, the process proceeds to Act 14.
In Act 14, the CPU 11a generates information for settlement regarding the registered product described in the registered product table as the m-th payment information based on the contents of the registered product table at this time. The payment information includes information such as a list of registered products and the total number and amount of purchased products. Thus, when the CPU 11a executes the control process based on the control program, the computer having the CPU 11a as the central portion functions as a generation unit.

In Act15, the CPU 11a uses a part of the screen of the touch panel 11g as the first selection screen.

FIG. 7 is a diagram showing a first selection screen SC3 as an example.
The first selection screen SC3 includes display areas AR1, AR2, AR3, AR4, AR5 and buttons B1, B2, B3, B4, B5, B6, B7, B8.

The CPU 11a represents the total number and the total amount of money included in the payment information in the display area AR1. The CPU 11a indicates whether or not the payment information can be transferred to each of the four payment devices 12 in the display areas AR2 to AR5. Note that the payment device 12 does not accept the transfer of payment information during the execution of the payment process, and the CPU 11a indicates "transfer not possible" in the display area associated with the payment device 12 in such a state. That is, when a part of the screen of the touch panel 11g is the first selection screen SC3, only the payment device 12 named “device A” is executing the payment process. The buttons B4 to B7 have different display forms depending on whether or not the associated payment device 12 accepts the transfer of payment information, or the associated payment device 12 accepts the transfer of payment information. If not, it may be hidden.

Buttons B1 and B2 are for the employee 21 to specify that a discount is applied to the total amount included in the payment information. Button B3 is for the employee 21 to specify that the purchase registration for the next accounting portion in the split accounting is started. Buttons B4 to B7 are for the employee 21 to specify the transfer of payment information to each of the four payment devices 12. The button B8 is for the employee 21 to specify to return to the state where a part of the screen area of the touch panel 11g is the registration screen.

If the CPU 11a determines No in Act 13 because the division flag is not set, the CPU 11a proceeds to Act 16.
In Act 16, the CPU 11a generates payment information for payment regarding the registered product described in the registered product table based on the contents of the registered product table at this time.
In Act 17, the CPU 11a uses a part of the screen of the touch panel 11g as the second selection screen.

FIG. 8 is a diagram showing a second selection screen SC4 as an example. In FIG. 8, the same elements as those in FIG. 7 are designated by the same reference numerals, and detailed description thereof will be omitted.
The second selection screen SC4 includes display areas AR1, AR2, AR3, AR4, AR5 and buttons B1, B2, B4, B5, B6, B7, B8.
That is, the second selection screen SC4 is a screen in which the button B3 is omitted from the first selection screen SC3. As a result, the second selection screen SC4 is a screen on which it is not possible to input the designation by the employee 21 to start the purchase registration for the split accounting.

The CPU 11a sets a part of the screen area of the touch panel 11g as the first or second selection screen in Act 15 or Act 17, and then proceeds to Act 18. The payment information generated by Act 14 or Act 16 is stored in the RAM 11c or the auxiliary storage unit 11d until one of the payment devices 12 is notified as described later. Therefore, the RAM 11c or the auxiliary storage unit 11d is an example of the storage unit.

In Act 18, the CPU 11a confirms whether or not the product code of the product to be registered for purchase has been acquired. Then, if the CPU 11a determines No because the product code has not been acquired, the CPU 11a proceeds to Act 19.
In Act 19, the CPU 11a confirms whether or not the payment device 12 as the transfer destination of the payment information is specified. Then, if the CPU 11a determines No because the payment device 12 is not specified, the CPU 11a proceeds to Act20.
In Act 20, the CPU 11a confirms whether or not the button B3 is touched. Then, if the CPU 11a determines No because the button B3 is not touched, the CPU 11a returns to Act18.
Thus, in Act18 to Act20, the CPU 11a waits for the product code to be acquired, one of the payment devices 12 to be specified, or the button B3 to be touched. However, when a part of the screen of the touch panel 11g is used as the second selection screen, the button B3 does not exist and the button B3 is not touched, so that the CPU 11a always determines No in Act20. It will be. That is, in the standby state of Act18 to Act20, if the division flag is not set, the CPU 11a waits for the product code to be acquired or for any of the payment devices 12 to be specified.
Although not shown, the CPU 11a also waits for the buttons B1 and B2 to be touched in this standby state. Then, if, for example, any of the buttons B1 and B2 is touched by the employee 21 and the touch panel 11g detects that, the CPU 11a responds to the subsequent instruction by the employee 21 with the total amount included in the payment information. To change.

When the CPU 11a acquires the product code, the CPU 11a determines Yes in Act 18 and proceeds to Act 21.
In Act 21, the CPU 11a uses a part of the screen of the touch panel 11g as a registration screen, then proceeds to Act 12 in FIG. 3, and repeats the subsequent processing in the same manner as described above.

If the touch panel 11g detects that the button B3 is touched while the CPU 11a is in the standby state of Act18 to Act12, the CPU 11a determines Yes in Act20 and proceeds to Act22.
In Act22, the CPU 11a increments the value of the variable m by one.
In Act23, the CPU 11a clears the registered product table.
After that, the CPU 11a returns to Act9 and repeats the processing after Act9. As a result, a plurality of payment information is generated.

Thus, only when the division flag is set, new creation of a list of purchased products in the registered product table is started even if the payment information described later is not transferred. That is, the CPU 11a prohibits the start of creating a new list until the settlement information is notified when the implementation of the split accounting is not decided, and the settlement information when the implementation of the split accounting is decided. Allows you to start creating a new list without being notified.
Therefore, when the CPU 11a executes the above control process based on the control program, the computer having the CPU 11a as the central portion functions as the first control unit.

When the CPU 11a is in the standby state of Act18 to Act20, the payment device 12 is designated by, for example, one of the buttons B4 to B7 of the first or second selection screens SC3 and SC4 being touched by the employee 21. If it is done, it is determined as Yes in Act19, and the process proceeds to Act24. Note that the CPU 11a does not determine Yes in Act 19 even if the button B4 to B7 associated with the payment device 12 that does not accept the transfer of payment information is touched. Thus, the CPU 11a does not accept the designation of the payment device 12 that does not accept the transfer of the payment information. If all of the payment devices 12 are in the stopped operation state or the operation state in which the transfer of payment information is not accepted, the CPU 11a specifies the payment device 12 in the standby state of Act18 to Act20. It will not stand by.

In Act 24, the CPU 11a transfers the payment information to the designated payment device 12. The payment information to be transferred here is the payment information generated by Act 16 when the division flag is not set, and one generated by Act 14 when the division flag is set. Or all of multiple payment information. Specifically, the CPU 11a controls the communication unit 11j so as to transmit the payment information to be transferred to the LAN 13 with the designated payment device 12 as the destination. As a result, the payment information is notified to the payment device 12. Thus, the CPU 11a executes the control process based on the control program, and the function as the notification unit is realized by the cooperation between the computer having the CPU 11a as the central portion and the communication unit 11j. Further, the CPU 11a receives the designation of the payment device 12 as an instruction for the notification of the payment information by the operator, and notifies the above payment information. Therefore, the computer having the CPU 11a as the central part controls the second. Functions as a department.

In Act25, the CPU 11a uses a part of the screen of the touch panel 11g as a notification screen. After that, the CPU 11a returns to Act1 in FIG. 3 and performs the subsequent processing in the same manner as described above.
The notification screen is a screen for causing the employee 21 to recognize that the payment information has been transferred to the payment device 12 for the semi-self payment. The semi-self settlement is a settlement form in which the settlement device 12 executes the settlement process in response to the operation by the shopper 22.
The notification screen may have the same content regardless of the state of the division flag, or may have different content depending on the state of the division flag.

FIG. 9 is a diagram showing a notification screen SC5 as an example.
The notification screen SC5 includes display areas AR11, AR12 and button B11.
The display area AR 11 represents an image for causing the employee 21 to recognize that the semi-self payment has been selected. The display area AR 12 represents an image for causing the employee 21 to recognize to which of the four payment devices 12 the payment information for two cases for split accounting has been transferred. That is, the notification screen SC5 has different contents depending on the state of the division flag, and is when the division flag is set.
The button B11 is for the employee 21 to instruct to close the notification screen SC5.

Then, the CPU 11a returns to Act1 in FIG. 3 in response to the touch of the button B11, and repeats the subsequent processing in the same manner as described above.
On the other hand, when the payment device 12 is activated, the CPU 12a starts the control process according to the control program stored in the ROM 12b or the auxiliary storage unit 12d.

10 and 11 are flowcharts of the control process of the CPU 12a.
In Act31, the CPU 12a uses the screen of the touch panel 12g as a standby screen. The standby screen indicates that the user is not in a situation where payment processing is performed, and what kind of information may be displayed may be arbitrary. For example, it is assumed that the standby screen represents a message indicating that payment processing cannot be performed, or displays an arbitrary image representing an advertisement or the like as a screen saver.

In Act 32, the CPU 12a confirms whether or not the payment information has been received. Then, the CPU 12a determines No if the payment information has not been received, and repeats Act32. Thus, the CPU 12a waits for the payment information to be received in Act32.

As described above, the communication unit 12j provided in the payment device 12 which is the destination of the payment information sent from the communication unit 11j of the product registration device 11 to the LAN 13 receives the payment information and receives the payment information in the RAM 12c or It is stored in the auxiliary storage unit 12d. When a plurality of payment information is sent, the communication unit 12j receives all of the plurality of payment information and stores them in the RAM 12c or the auxiliary storage unit 12d. In response to this, the CPU 12a determines Yes in Act32 and proceeds to Act33.

In Act33, the CPU 12a confirms whether or not the received payment information is plural. Then, when only one payment information is received, the CPU 12a determines No and proceeds to Act34.
In Act34, the CPU 12a changes the screen of the touch panel 12g to a payment screen.
The payment screen accepts an operation by the shopper 22 for making a payment based on the one received payment information. The payment screen represents, for example, at least the total amount shown in the payment information. The payment screen may also include a total number of items and a list of purchased items. Further, if payment by a plurality of payment methods is allowed, the payment screen includes a button for the shopper 22 to select the payment method.

In Act35, the CPU 12a confirms whether or not the operation by the shopper 22 for settlement has been performed. Then, if the CPU 12a determines No because the corresponding operation has not been performed, the CPU 12a repeats Act 35. Thus, the CPU 12a waits for the operation for settlement to be performed in Act35.

By the way, when the employee 21 who operates the product registration device 11 touches any of the buttons B4 to B7 of the first or second selection screens SC3 and SC4 to transfer the payment information to any of the payment devices 12. , Notifies the shopper 22 that payment should be made by the payment device 12 at the transfer destination. Upon receiving this notification, the shopper 22 moves to the designated payment device 12 and performs an operation for payment on the above-mentioned payment screen. Then, the CPU 12a determines that the operation for settlement is performed in this way, and if this is detected by the touch panel 12g, it is determined as Yes by the Act 35, and the process proceeds to the Act 36.

In Act36, the CPU 12a executes a payment process. The settlement process here is a process for settling the total amount shown in the settlement information stored in the RAM 12c or the auxiliary storage unit 12d in response to the operation by the shopper 22. For the settlement process here, for example, the process performed by an existing self-POS terminal or the like can be applied as it is. Thus, when the CPU 12a executes the control process based on the control program, the computer having the CPU 12a as the central portion functions as a settlement unit.

In Act37, the CPU 12a controls the printer 12h and issues a receipt showing the information shown in the payment information stored in the RAM 12c or the auxiliary storage unit 12d and the result of the above payment processing. Then, the CPU 12a returns to Act31 after this, and performs the subsequent processing in the same manner as described above.

If the CPU 12a receives a plurality of payment information, the CPU 12a determines Yes in the Act 33, and proceeds to the Act 38 in FIG.
In Act38, the CPU 12a sets "1" as the value of the variable n.
In Act39, the CPU 12a uses a part of the screen of the touch panel 11g as a selection screen. The selection screen is a screen for allowing the shopper 22 to select individual payment or batch payment. The individual settlement represents a settlement form in which settlement is individually performed according to each of a plurality of settlement information. In addition, the batch settlement represents a payment form in which payments according to a plurality of payment information are collectively performed.

In Act40, the CPU 12a confirms whether or not the batch settlement is selected. Then, if the CPU 12a determines No because the batch settlement is not selected, the CPU 12a proceeds to Act 41.
In Act 41, the CPU 12a confirms whether or not the split settlement is selected. Then, if the CPU 12a determines No because the split settlement is not selected, the CPU 12a returns to Act40.
Thus, the CPU 12a waits for the batch settlement or the split settlement to be selected in the Act 40 and the Act 41. The CPU 11a may confirm the occurrence of another event such as another operation being performed in the standby here, and may shift to the processing according to the occurrence event.

If the operation of selecting individual payment is detected by, for example, the touch panel 11g, the CPU 12a determines Yes in Act 41 and proceeds to Act 42.
In Act 42, the CPU 12a executes a payment process based on the nth payment information.
In Act43, the CPU 12a controls the printer 12h and issues a receipt showing the information shown in the nth payment information and the result of the above payment processing.
In Act44, the CPU 12a increments the value of the variable n by one.

In Act 45, the CPU 12a confirms whether or not the nth payment information exists in the payment information stored in the RAM 12c or the auxiliary storage unit 12d. Then, the CPU 12a returns to Act42 if the nth payment information exists, and performs Act42 and Act43 on the payment information. After the CPU 12a finishes executing Act42 and Act43 for all the payment information stored in the RAM 12c or the auxiliary storage unit 12d, the CPU 12a determines Yes in Act45. Then, in this case, the CPU 12a returns to Act 31 in FIG. That is, the CPU 12a returns to the state of waiting for new payment information to be received.
In this way, when the individual payment is selected by the shopper 22, the CPU 12a sequentially performs the payment processing based on each of the plurality of payment information, and issues a receipt each time.

When the CPU 12a is in the standby state of Act 40 and Act 41, if the operation of selecting batch payment is detected by, for example, the touch panel 11g, the CPU 12a determines Yes in Act 40 and proceeds to Act 46. Thus, when the CPU 12a executes the above control process based on the control program, the computer having the CPU 12a as the central portion functions as a setting unit.

In Act46, the CPU 12a calculates the total amount of the total amount shown in each of the payment information stored in the RAM 12c or the auxiliary storage unit 12d.
In Act47, the CPU 12a executes a settlement process for settling the above total amount.
In Act 48, the CPU 12a controls the printer 12h and issues a receipt showing the information shown in the nth payment information and the result of the above payment processing.

Thus, when a plurality of payment information is received, a plurality of receipts corresponding to each of the plurality of payment information will be issued in both the processing loops of Act42 to Act45 and the processing loop of Act48. .. Therefore, when the CPU 12a executes the above control process based on the control program, the computer having the CPU 12a as the central portion functions as a issuing unit.

In Act49, the CPU 12a increments the value of the variable n by one.
In Act 50, the CPU 12a confirms whether or not the nth payment information exists in the payment information stored in the RAM 12c or the auxiliary storage unit 12d. Then, the CPU 12a returns to Act48 if the nth payment information exists, and performs Act48 on the payment information. After the CPU 12a finishes executing Act 48 for all the payment information stored in the RAM 12c or the auxiliary storage unit 12d, the CPU 12a determines Yes in Act 50. Then, in this case, the CPU 12a returns to Act 31 in FIG. That is, the CPU 12a returns to the state of waiting for new payment information to be received.

In this way, when the batch payment is selected by the shopper 22, the CPU 12a settles the total amount of the total amount shown in each of the plurality of payment information in one payment process. However, receipts will be issued in sequence based on each of the multiple payment information.

As described above, the product registration device 11 normally transfers only one payment information based on the purchase registration for one accounting to one of the payment devices 12. When one payment information is transferred in this way, the payment device 12 does not accept the transfer of another payment information until the payment processing based on the payment information is completed.

However, when the shopper 22 desires split accounting, the product registration device 11 continuously performs purchase registration for a plurality of accounts and generates a plurality of payment information according to the purchase registration. Then, the product registration device 11 collectively transfers the plurality of payment information to one of the payment devices 12. When the plurality of payment information is transferred in this way, the payment device 12 performs a payment process based on the plurality of payment information.
Thus, according to the checkout system 10, the shopper 22 can use the split accounting and does not need to operate the plurality of payment devices 12 for each settlement of the plurality of accounts.

Further, according to the checkout system 10, the shopper 22 can arbitrarily use the split settlement and the lump sum settlement even when the split accounting is performed. Then, regardless of whether the payment is divided or settled in a lump sum, a plurality of receipts corresponding to each of the plurality of payment information are issued. Therefore, the shopper 22 can obtain a receipt recording the result of the split settlement regardless of whether the split settlement or the batch settlement is used.
