(Functional configuration of POS terminal device 20)
Here, when using a prepaid card, in addition to forgetting to take out the prepaid card, there are also cases where the next customer charges the card unintentionally. This will be explained by giving an example. For example, in the case of a prepaid card whose charge balance is managed by the charge management server Sv, when the POS terminal device 20 reads the card information of the prepaid card, it queries the charge management server Sv about the charge balance based on the card information. , display the remaining charge amount. The charge remaining amount display screen is, for example, a screen that accepts designation of the charge remaining amount and the charge amount (for example, the amount confirmation screen 530 in FIG. 5C, which will be described later).

In particular, some POS terminal devices 20 display the amount confirmation screen 530 when the card information of a prepaid card is read, and immediately eject the prepaid card. For example, some POS terminal devices 20 continue to display the amount confirmation screen 530 until it receives an operation to close it, regardless of whether charging is performed or not. In this type of POS terminal device 20, if the customer leaves while displaying the amount confirmation screen 530, the amount confirmation screen 530 becomes viewable by the next customer. Furthermore, if the next customer deposits money in accordance with the display on the amount confirmation screen 530, the previous customer's prepaid card will be charged unintentionally. For this reason, customers were sometimes unable to properly handle their prepaid cards.

Therefore, in this embodiment, appropriate handling of prepaid cards is supported. The functional configuration of the POS terminal device 20 according to this embodiment will be described below with reference to FIG. 4.

FIG. 4 is an explanatory diagram showing an example of the functional configuration of the POS terminal device 20. As shown in FIG. The POS terminal device 20 described below will be described as operating in an accounting-only mode. In FIG. 4, the POS terminal device 20 includes a reading section 401, an operation reception section 402, a notification section 403, a payment section 404, and a change reception section 405. Each functional unit is realized by the CPU 201 of the POS terminal device 20. That is, the CPU 201 of the POS terminal device 20 executes a predetermined program (such as a charging program) to realize the functions of each functional unit. Each functional unit shown in FIG. 4 will be described below with reference to the display screens shown in FIGS. 5 to 7.

In the accounting-only mode, the POS terminal device 20 can be in one of two states: on standby, where payment is not being made, and in payment mode, where payment is being made. It is possible to start charging the charge medium in either the standby state or the payment state. First, charging that starts during standby will be explained.

A reading unit 401 reads medium information of a charge medium. The charging medium is, for example, a contact type prepaid card. The prepaid card stores card identification information for identifying the prepaid card as medium information. The charging medium is, for example, an IC card or a magnetic card. The charge remaining amount is managed by the charge management server Sv. The reading section 401 is a contact type reader that reads card information of a prepaid card inserted into the card insertion section.

Note that the charging medium includes a non-contact type charging medium. The contactless charging medium is, for example, a contactless card (IC card) or a mobile terminal device such as a smartphone. In the case of a non-contact type charging medium, medium information such as the remaining charge amount is directly stored in a storage unit such as an IC chip built into the non-contact type charging medium. The reading unit 401 includes not only a contact type reader but also a non-contact type reader. A contactless reader allows a customer to read information on the remaining charge amount by holding the contactless charge medium over the reader.

FIGS. 5 and 6 are explanatory diagrams showing a series of charging screens when charging is started during standby. Note that each screen of FIGS. 5 and 6, which will be described below, includes an example of a plurality of charging screens that change depending on an operation related to charging the charging medium.

FIG. 5(A) shows a standby screen 510 in the accounting-only mode. The standby screen 510 indicates the accounting-only mode and indicates that the system is on standby. Standby screen 510 includes a charge button 511. The charge button 511 is a button for displaying the remaining charge amount and accepting the start of the charge procedure. Since the charge button 511 accepts the display of the remaining charge amount and the start of the charge procedure with a single button operation, the display area on the standby screen 510 can be simplified. However, the display of the charge remaining amount and the start of the charge procedure may be accepted using separate buttons. That is, the POS terminal device 20 displays the remaining charge amount in response to pressing a button that accepts the display of the remaining charge amount, and displays a screen for performing the charging procedure in response to pressing the button that accepts the start of the charging procedure. You can do it like this. Thereby, a screen desired by the customer can be displayed with a simple operation.

A customer using a prepaid card presses a charge button 511 on the standby screen 510 when checking the remaining charge amount. When the charge button 511 is pressed, the screen changes to a card insertion reminder screen 520 shown in FIG. 5(B).

When the cancel button 521 is pressed on the card insertion reminder screen 520, the screen returns to the standby screen 510 in FIG. 5(A). When the prepaid card is inserted into the card insertion section on the card insertion reminder screen 520, the screen changes to an amount confirmation screen 530 shown in FIG. 5(C).

FIG. 5C shows an amount confirmation screen 530. The amount confirmation screen 530 includes a remaining amount display 531, an amount specification button 532, and a cancel button 533. The remaining amount display 531 shows the remaining amount charged on the prepaid card. The remaining charge amount shown in the remaining amount display 531 is obtained based on the medium information (card identification information) read by the reading unit 401. Note that the name and membership number of the customer (member) may be displayed on the amount confirmation screen 530.

The amount specification button 532 is a button that accepts specification of the amount to be charged. When the amount specification button 532 (for example, a "1000 yen" button) is pressed, the screen transitions to a deposit acceptance screen 610 shown in FIG. 6(A). The cancel button 533 is a button that accepts the cancellation of charging or a button that accepts the end (cancellation) of balance inquiry. When the cancel button 533 is pressed, the prepaid card is ejected from the card payment unit 208 (card insertion unit), and the return notification 540 shown in FIG. 5(D) is displayed.

In FIG. 5(D), a return notification 540 is a pop-up display superimposed on the amount confirmation screen 530. The return notification 540 indicates a notification prompting the user to take out the prepaid card due to the return of the prepaid card. The return notification 540 is displayed until the prepaid card is removed from the card insertion section. When the prepaid card is removed from the card insertion section, the return notification 540 is erased and the screen returns to the standby screen 510 shown in FIG. 5(A).

FIG. 6A shows a deposit reception screen 610. The deposit reception screen 610 shows a notification prompting the user to insert the specified charge amount into the change machine 209. The deposit acceptance screen 610 includes a customer information display 611, a specified charge amount display 612, a deposited amount display 613, and a cancel button 614. The customer information display 611 includes the member name, member number, and remaining charge amount. Thereby, the customer can check whether the member name is correct on the deposit reception screen 610, and can also check the remaining amount.

The specified charge amount display 612 shows the charge amount (1000 yen) accepted by the amount specification button 532 on the amount confirmation screen 530 in FIG. 5(C). The input amount display 613 is an area that shows the amount of money that has been input, and in the illustration, it shows "0 yen". The cancel button 614 is a button that accepts canceling charging. When the cancel button 614 is pressed, the prepaid card is ejected and a return notification 540 (FIG. 5(D)) is superimposed on the deposit reception screen 610.

Note that when the cancel button 614 is pressed, the return notification 540 is not limited to being displayed, and the screen may be returned to the previous screen (the amount confirmation screen 530 in FIG. 5(C)). When cash for the designated charge amount is inserted on the deposit acceptance screen 610, the screen changes to an amount confirmation screen 620 shown in FIG. 6(B).

FIG. 6(B) shows an amount confirmation screen 620. In the amount confirmation screen 620, the input amount display 613 shows "1000 yen", that is, 1000 yen of cash has been inserted. The amount confirmation screen 620 includes a charge confirmation button 621. The charge confirmation button 621 is a button that accepts confirmation of charge according to the contents shown in the specified charge amount display 612 and input amount display 613.

Note that on the amount confirmation screen 620, the cancel button 614 shown in FIG. 6(A) is not displayed, that is, the refund after deposit is not allowed. For example, if the customer were to approve the return, even though the customer had deposited a 5,000 yen bill, the customer would have intentionally or misunderstood the situation and said, ``I deposited a 10,000 yen bill, but I only received 5,000 yen.'' This is because there is a risk that financial troubles may arise due to a request that the item not be returned. In this embodiment, such financial troubles are prevented by not displaying the cancel button 614 in FIG. 6(A) on the amount confirmation screen 620.

When the charge confirmation button 621 is pressed, a return notification 630 in FIG. 6(C) is displayed and the prepaid card is ejected.

In FIG. 6(C), a return notification 630 is a pop-up display superimposed on the amount confirmation screen 620. The return notification 630 indicates a notification prompting the user to take out the prepaid card due to the return of the prepaid card. The return notification 630 is displayed until the prepaid card is removed from the card insertion section. When the prepaid card is removed from the card insertion section, the return notification 630 is erased and the screen transitions to a charge completion screen 640 shown in FIG. 6(D).

FIG. 6(D) shows a charge completion screen 640. The charging completion screen 640 indicates that charging is completed and a receipt (charging slip) will be issued. In the charge completion screen 640, the charge remaining amount in the customer information display 611 indicates the amount (¥1287) to which the charged amount (¥1000) has been added. When the charge slip is taken out on the charge completion screen 640, the screen returns to the standby screen 510 shown in FIG. 5(A). Note that the condition for returning to the standby screen 510 is not limited to the fact that the charging slip is taken out, but may also be the pressing of the end button 641 or the elapse of a predetermined time.

In this way, in this embodiment, it is possible to start charging during standby in the transaction-only mode. Furthermore, by displaying the customer information display 611 on each screen shown in FIGS. 6(A) to 6(D), the customer can also check the member name and balance amount on a series of screens. ing.

(Regarding the functional configuration for performing screen transitions shown in Figures 5 and 6)
In FIG. 4, the operation accepting unit 402 accepts a predetermined operation related to performing charging on each of the plurality of charging screens that change after the card identification information is read. Examples of multiple charging screens are listed below.
- Amount confirmation screen 530 in FIG. 5(C).
- Deposit acceptance screen 610 in FIG. 6(A).
- Amount confirmation screen 620 in FIG. 6(B).

The predetermined operations include a stop operation to stop charging and a charge operation to start charging. Examples of predetermined operations are listed below.
- Pressing the cancel button 533 on the amount confirmation screen 530 in FIG. 5(C) (cancel operation).
- Pressing the cancel button 614 on the deposit reception screen 610 in FIG. 6(A) (cancel operation).
- Pressing the charge confirmation button 621 on the amount confirmation screen 620 in FIG. 6(B) (completion operation among charge operations).

Pressing the stop button 533 includes an operation to finish checking the remaining charge amount of the prepaid card and an operation to stop charging. The cancel button 533 is not limited to accepting the end of checking the charge remaining amount and canceling the charge with one button, but may be configured with separate buttons. That is, the POS terminal device 20 may separately display a button for accepting the end of checking the charge remaining amount and a button for accepting the cancellation of the charge.
Pressing the stop button 614 includes an operation to stop charging.
Pressing the charge confirmation button 621 is a completion operation to complete charging.

Note that the charge operation for charging is not limited to the completion operation by pressing the charge confirmation button 621, but also the determination operation to determine the charge amount shown in (1) or (2) below, or the deposit related to the deposit for charge. It can also be used as an operation.
(1) Determination operation: For example, pressing the amount specification button 532 on the amount confirmation screen 530 in FIG. 5(C).
(2) Deposit operation: For example, an operation to deposit a specified charge amount on the deposit reception screen 610 in FIG. 6(A).

The POS terminal device 20 ejects the prepaid card at a timing corresponding to receiving a predetermined operation. In addition, the notification unit 403 makes notifications indicating the return of the prepaid card (return notifications) at different timings in response to receiving a predetermined operation. Specifically, the notification unit 403 performs a return notification indicating the return of the prepaid card at a timing corresponding to receiving a predetermined operation, that is, at a timing when the prepaid card is ejected. Specifically, the return notification is a return notification 540 in FIG. 5(D) or a return notification 630 in FIG. 6(C). The return notifications 540 and 630 may include a warning sound or the audio of the notification content. The timing at which the return notifications 540 and 630 are performed is the timing at which a predetermined operation is received, but is not limited thereto, and may be at a timing several seconds after the timing at which the predetermined operation is received.

The notification unit 403 continues the return notifications 540 and 630 until the ejected prepaid card is taken out, and ends the return notifications 540 and 630 when the prepaid card is removed. Specifically, the notification unit 403 ends the return notifications 540 and 630 when the sensor included in the card insertion unit detects that the prepaid card has been removed. The POS terminal device 20 may not proceed to the next screen until the prepaid card is removed, that is, while the return notifications 540 and 630 are being made.

In this way, the POS terminal device 20 according to the present embodiment does not eject the prepaid card immediately after reading the card information of the prepaid card, but ejects the prepaid card at a timing corresponding to the customer's operation. Return notifications 540 and 630 are made.

Note that when the charging operation is a decision operation as in (1) above (when the amount specification button 532 is pressed), the notification unit 403 issues a return notification at the timing corresponding to the amount specification button 532 being pressed. Just do it. Furthermore, when the charge operation is a deposit operation as described in (2) above (when the charge operation is an input operation of the charge amount), the notification unit 403 displays a return notification 630 at a timing corresponding to the input of the charge amount. Just do it like this. The timing according to the input of the charge amount may be the timing when the first coin is inserted when multiple coins are inserted, or the timing when an amount equal to or greater than the amount indicated by the designated charge amount display 612 is inserted. good.

In this way, the POS terminal device 20 can eject the prepaid card at a timing corresponding to the customer's operation and notify the customer of the return.

FIG. 7 is an explanatory diagram showing a series of charging screens when charging is performed during payment. Note that each screen in FIG. 7, which will be described below, includes an example of a plurality of charging screens that change depending on an operation related to charging the charging medium.
FIG. 7A shows a payment type selection screen 710 that is displayed when payment information is received from the POS terminal device 20 in clerk registration mode. The payment type selection screen 710 is a screen displayed based on the payment information received on the standby screen 510 of FIG. 5(A).

The payment type selection screen 710 includes a payment amount display 711 and a payment type selection button 712. The payment amount display 711 shows the total payment amount (for example, 587 yen) to be paid by the customer. The payment type selection button 712 is a button that accepts a selection among "cash," "credit card," "IC card," and "code payment." Note that "IC card" indicates payment using a charging medium. The notation of "IC card" may be simply "IC" or "charge medium." “Code payment” refers to payment using, for example, a QR code (registered trademark) for payment displayed on a smartphone or the like.

When "IC card" is selected on the payment type selection screen 710, the screen transitions to a card insertion reminder screen 520 in FIG. 5(B). Then, a prepaid card is accepted from the customer. Here, it is assumed that the charge balance of the prepaid card accepted from the customer on the card insertion reminder screen 520 is 287 yen. That is, it is assumed that the remaining charge amount (287 yen) is insufficient for the amount shown in the payment amount display 711 (587 yen). For this reason, the POS terminal device 20 changes to the card insertion reminder screen 520, and then changes to the amount confirmation screen 530 shown in FIG. 5(C) in order to perform the charging procedure.

Note that the transition to the amount confirmation screen 530 may be made regardless of whether or not the remaining charge amount (287 yen) is insufficient for the amount shown in the payment amount display 711 (587 yen). Further, a button for accepting a charge may be displayed on the payment type selection screen 710, and when the button is pressed, insertion of a prepaid card may be accepted and the screen may be transited to the amount confirmation screen 530.

Here, assume that the cancel button 533 is pressed on the amount confirmation screen 530 shown in FIG. 5(C). In this case, the prepaid card is not ejected and the return notification is not performed, and the screen returns to the payment type selection screen 710. The ejection and return notification of the prepaid card shall be made upon completion of payment. When the amount specification button 532 (eg, "1000 yen" button) is pressed on the amount confirmation screen 530, the screen transitions to a deposit acceptance screen 610 shown in FIG. 6(A).

It is also assumed that the cancel button 614 is pressed on the deposit acceptance screen 610. In this case as well, the prepaid card is not ejected and the return notification is not performed, and the screen returns to the payment type selection screen 710. The ejection and return notification of the prepaid card shall be made upon completion of payment. When cash for the designated charge amount is inserted on the deposit acceptance screen 610, the screen changes to an amount confirmation screen 620 shown in FIG. 6(B).

Then, when the charge confirmation button 621 is pressed on the amount confirmation screen 620, the POS terminal device 20 completes the payment taking into account the charge amount, and displays the payment completion screen including the return notification 720 shown in FIG. 7(B). 730.

In FIG. 7(B), a return notification 720 is a pop-up display superimposed on a payment completion screen 730, which will be described later. The return notification 720 indicates a notification prompting the user to take out the prepaid card due to the return of the prepaid card upon completion of payment. The return notification 720 is displayed until the prepaid card is removed from the card insertion section.

In this embodiment, in order to simplify the operation, the charge confirmation button 621 is used to complete the payment and display the return notification 720. Here, when charging is in progress, the condition for displaying the return notification 720 is not confirmation of charging but completion of payment. For this reason, for example, when the charge confirmation button 621 is pressed on the amount confirmation screen 620 shown in FIG. The return notification 720 may be displayed after the payment is completed by pressing the payment start button.

In the return notification 720, when the prepaid card is removed from the card insertion section, the return notification 720 is erased and the screen transitions to a payment completion screen 730 shown in FIG. 7(C).
FIG. 7(C) shows a payment completion screen 730. The payment completion screen 730 shows a screen indicating that the payment has been completed because "1000 yen" has been charged. In the customer information display 611 of the payment completion screen 730, the remaining charge amount after payment is shown as "700 yen." The remaining charge amount is the sum of the charge amount "1000 yen" and the charge balance before settlement "287 yen" (1287 yen) minus the payment amount "587 yen". When the receipt is taken out on the payment completion screen 730 or when a predetermined time period has elapsed, the screen returns to the standby screen 510 shown in FIG. 5(A).

(Regarding the functional configuration for performing screen transitions shown in Figures 7(A) to (C))
In FIG. 4, a payment unit 404 performs payment based on payment information. The payment information is acquired by being transmitted from the POS terminal device 20 in clerk registration mode. However, the present invention is not limited thereto, and the payment information may be obtained by reading a code (two-dimensional code) printed on a predetermined medium (paper medium or electronic medium).

The operation reception unit 402 accepts a predetermined operation on any one of the plurality of charge screens displayed at the time of payment performed by the payment unit 404. As mentioned above, the multiple charge screens are as follows.
- Amount confirmation screen 530 in FIG. 5(C).
- Deposit acceptance screen 610 in FIG. 6(A).
- Amount confirmation screen 620 in FIG. 6(B).

Furthermore, as described above, the predetermined operations are as follows.
- Cancel button 533 in FIG. 5(C).
- Cancel button 614 in FIG. 6(A).
- Charge confirmation button 621 in FIG. 6(B).

When payment is started, the notification unit 403 issues a return notification 740 at a timing different from the timing at which the predetermined operation is received.

(Examples of other timings)
Other timings are, for example, timings that correspond to the completion of payment. The timing corresponding to the completion of the payment is, for example, the timing when the payment is completed. In other words, when the payment with the prepaid card is selected and the payment is started, the notification unit 403 does not issue a return notification even if there is an operation to cancel the payment with the prepaid card, and at the timing of completion of the payment. Notify of return.

In addition, from the viewpoint of preventing the customer from leaving with the amount confirmation screen 530 displayed, the other timing may be a timing before the payment is completed. The timing before the completion of payment is, for example, each of the following timings (3) to (5).
(3) Timing corresponding to pressing of the amount specification button 532 (for example, "1000 yen" button) on the amount confirmation screen 530 in FIG. 5(C).
(4) Timing when the designated charge amount on the amount confirmation screen 620 corresponds to the input. For example, the timing when the first coin is inserted, or the timing when an amount greater than the specified charge amount is inserted.
(5) Timing corresponding to the selection of a payment type other than prepaid card in selecting the payment type again by pressing the cancel button 533 (FIG. 5(C)) or the cancel button 614 (FIG. 6(A)).
Even if the return notification is made at any of the timings (3) to (5) above, since the customer has started the operation related to payment, it is possible that the customer leaves with the amount confirmation screen 530 displayed. It can be prevented.

(When changing payment type from prepaid card to credit card)
Only one type of card can be inserted into the card insertion section of the POS terminal device 20 according to this embodiment. Therefore, if a prepaid card is inserted into the card insertion section, a credit card cannot be inserted into the card insertion section. Therefore, as shown in FIG. 7(D), when the payment type selection button 712 for credit card is pressed in selecting the payment type again, the POS terminal device 20 issues a return notification 740. Specifically, when the cancel button 533 is pressed on the amount confirmation screen 530 (FIG. 5(C)) during payment, or when the cancel button 614 is pressed on the deposit acceptance screen 610 (FIG. 6(A)) during payment. When pressed, the screen returns to the payment type selection screen 710 shown in FIG. 7(A). If "credit card" is selected from among the payment type selection buttons 712 on the payment type selection screen 710, the POS terminal device 20 returns the prepaid card and issues a return notification 740.

The return notification 740 indicates a notification prompting the user to take out the prepaid card because the prepaid card has been returned in response to the selection of credit card as the payment type. The return notification 740 is displayed until the prepaid card is removed from the card insertion section. In the return notification 740, when the prepaid card is removed from the card insertion section, the POS terminal device 20 transitions to a screen (not shown) prompting the user to insert the credit card into the card payment section 208 (card insertion section), Make payment by credit card.

Note that in the selection of the payment type again, if a payment type other than credit card is selected, the notification unit 403 may or may not return the prepaid card and notify the return. If the return notification is not performed at the selected timing, the notification unit 403 may perform the return notification at a timing corresponding to the completion of payment.

(Regarding the functional configuration for performing screen transitions shown in Figure 7)
As described above, only one type of card can be inserted into the card insertion section of the POS terminal device 20 according to this embodiment. That is, the reading unit 401 shown in FIG. 4 can read either the card identification information of the prepaid card or the card information of the credit card.

The change reception unit 405 accepts changes in the payment type after the start of payment. Specifically, the change reception unit 405 changes when the cancel button 533 is pressed on the amount confirmation screen 530 (FIG. 5(C)) during payment, or when the payment reception screen 610 (FIG. 6(A)) during payment is pressed. If the cancel button 614 is pressed in , a payment type selection screen 710 shown in FIG. 7(A) is displayed and a change in the payment type is accepted.

Here, the change reception unit 405 may display different payment type selection screens 710 before the start of payment and after the start of payment, and accept changes in the payment type. Specifically, if a cancellation of payment using a prepaid card is accepted after payment has started, there is a low possibility that a prepaid card will be selected again, so "prepaid card" is made unselectable from among the payment type selection buttons 712. It's okay. Unselectable means hidden or grayed out.

The notification unit 403 provides return notification at a timing corresponding to accepting a change in the payment type from a prepaid card payment type to a credit card payment type. Specifically, when the "credit card" of the payment type selection buttons 712 is pressed in selecting the payment type again, the notification unit 403 issues a return notification 740 shown in FIG. 7(D).

(Charging process started by POS terminal device 20 during standby)

As shown in FIG. 9, the POS terminal device 20 determines whether settlement information has been received from the POS terminal device 20 in the accounting-only mode on the standby screen 510 (FIG. 5(A)) (step S901). The POS terminal device 20 waits until payment information is received (step S901: NO), and when the payment information is received (step S901: YES), it displays the payment type selection screen 710 of FIG. 7(A) and performs payment. The selection of the type is accepted (step S902).

Then, the POS terminal device 20 determines whether a prepaid card has been selected (step S903). If a prepaid card is not selected (step S903: NO), that is, if a payment type other than a prepaid card is selected, the POS terminal device 20 proceeds to the process of step S923 in FIG. 10. On the other hand, if a prepaid card is selected (step S903: YES), the POS terminal device 20 determines whether a prepaid card is inserted into the card insertion section (step S904).

The POS terminal device 20 waits until the prepaid card is inserted into the card insertion section (step S904: NO), and when the prepaid card is inserted into the card insertion section (step S904: YES), charges the charge management server Sv. The charge amount is queried and the remaining charge amount is obtained (step S905).

Then, the POS terminal device 20 displays the remaining charge amount (step S906). Next, the POS terminal device 20 determines whether the remaining charge amount is insufficient for the payment amount (step S907). If the remaining charge amount is not insufficient for the payment amount (step S907: NO), the POS terminal device 20 proceeds to step S917 in FIG. 10.

If the remaining charge amount is insufficient for the payment amount (step S907: YES), the POS terminal device 20 displays the amount confirmation screen 530 of FIG. It is determined whether or not (step S911). If the designation of the charging amount is not accepted (step S911: NO), the POS terminal device 20 determines whether or not the charging procedure is to be canceled by pressing the cancel button 533 (step S912).

If the charging procedure is not canceled (step S912: NO), the POS terminal device 20 returns to step S911. On the other hand, when canceling the charging procedure (step S912: YES), the POS terminal device 20 proceeds to step S921.

Then, the POS terminal device 20 accepts insertion of a credit card into the card insertion section (step S925). Next, the POS terminal device 20 executes payment processing using a credit card (step S926), and proceeds to step S920.

As explained above, the POS terminal device 20 according to the present embodiment is capable of accepting a predetermined operation related to the execution of charging on each of the multiple charging screens that transition after the card identification information of the prepaid card is read. A return notification indicating the return of the prepaid card is made at a timing corresponding to the prepaid card. Thereby, the prepaid card can be returned and the return notification can be performed at different timings each time according to the customer's operation. Therefore, it is possible to prevent the customer from leaving during the charging operation, and also to prevent the customer from forgetting to take out the card. Therefore, according to this embodiment, it is possible to support appropriate handling of prepaid cards.

Further, the POS terminal device 20 according to the present embodiment provides a return notification when either an operation to cancel charging or a charging operation to perform charging is performed. As a result, the prepaid card can be returned and the return notification can be performed at a timing corresponding to the customer's charging stop operation or charging operation. Therefore, it is possible to prevent the customer from leaving during the charging operation, and also to prevent the customer from forgetting to take out the card.

Further, in the POS terminal device 20 according to the present embodiment, any one of a determination operation for determining the amount of charge, a deposit operation for depositing money in charge, and a completion operation for completing charge is performed. By doing so, we will notify you of the return. Thereby, in the charging operation, the prepaid card can be returned and the return notification can be performed at different timings. Therefore, it is possible to more efficiently prevent customers from leaving in the middle of charging operations and from forgetting to take out their cards.

Further, the POS terminal device 20 according to the present embodiment accepts a predetermined operation on each of the plurality of charging screens at the time of payment, and when the payment is started, the timing corresponding to accepting the predetermined operation is Return notifications are made at different timings. Thereby, during payment, it is possible to return the prepaid card and notify the return at a timing different from that during standby. Therefore, during payment, it is possible to prevent the customer from leaving in the middle of the operation, and it is also possible to prevent the customer from forgetting to take out the card.

Further, in the POS terminal device 20 according to the present embodiment, the different timing is a timing corresponding to the completion of payment. In other words, the POS terminal device 20 does not issue a return notification even if a payment is started in which payment with a prepaid card is selected and there is an operation to cancel payment with a prepaid card, and the POS terminal device 20 is returned at the timing of completion of the payment. Make announcements. Thereby, when the payment is completed, the prepaid card can be returned and the return notification can be performed. If the prepaid card is returned and the return notification is performed before the payment is completed, there is a risk that the customer may mistakenly believe that the payment has been completed even though the payment has not yet been completed. On the other hand, such misrecognition can be suppressed by returning the prepaid card and notifying the user of the return upon completion of payment. As a result, it is possible to prevent the customer from leaving in the middle of an operation before the payment is completed, and it is also possible to prevent the customer from forgetting to take the card.

Further, the POS terminal device 20 according to the present embodiment issues a return notification at a timing corresponding to accepting a change in the payment type from a prepaid card to a credit card. Thereby, even if the POS terminal device 20 according to the present embodiment is capable of inserting only one type of card into the card insertion section, it is possible to appropriately return the prepaid card and notify the return.

Note that in the above description, the payment information is acquired from the POS terminal device 20 in the clerk registration mode, but the present invention is not limited to this. The payment information may be generated by the own device, that is, by self-registration in full self-mode. In other words, the POS terminal device 20 can start the charging procedure while waiting in full self-mode, and can also start the charging procedure while paying in full-self mode.

Further, the payment information is not limited to being generated by the POS terminal device 20 in clerk registration mode or the POS terminal device itself, but may be generated by a terminal device owned by the customer. To be more specific, the terminal device transmits registered product information to an external server device in response to operations by a customer shopping while walking around the store. When the terminal device accepts the start of payment, the terminal device receives payment information from an external server device and displays the payment information on the display using a two-dimensional code. The two-dimensional code displayed on the display is read by the customer-side scanner unit 206 of the POS terminal device 20 by the customer's operation. Thereby, the POS terminal device 20 can acquire payment information from the terminal device and perform payment using a prepaid card. Note that the POS terminal device 20 that performs the payment may be set to an accounting-only mode or may be set to a full-self mode.

Note that all or part of each function (input/output, storage, processing (including judgment, etc.)) of the POS terminal device 20 explained above may be performed in a device different from the device explained as the main body executing the function. It may be realized.

For example, instead of the POS terminal device 20, the store controller 10, charge management server Sv, or cloud server (not shown) may control reading of media information or perform predetermined operations on each of a plurality of charge screens. You may also perform control regarding acceptance and return notification. Specifically, for example, another device may execute the processing performed by the POS terminal device 20 (see FIGS. 8 to 10) instead of the POS terminal device 20.

Furthermore, in the above description, the configuration in which the POS terminal device 20 includes the reading section 401, the operation reception section 402, the notification section 403, the payment section 404, and the change reception section 405 has been described. All or part of the functional units may be included in another computer device. For example, all or part of these functional units may be included in the store controller 10, a cloud server, or a computer device other than these. Further, the number of computer devices equipped with these functional units is not limited to a plurality of devices, and may be one computer device. For example, one computer device may include all of these functional units.

In relation to the above, the POS terminal device 20 has special functions in the input/output interface part regarding control related to reading media information, control accepting predetermined operations on each of the plurality of charging screens, and control related to return notification. It may also function as a so-called thin client. In other words, the POS terminal device 20 accepts various inputs (operator operations, detections by devices such as scanners), sends the input information (operation information, scan information, etc.) to the cloud server, and uses the input information to The processing results of the server (updated screen information, device control information, etc.) may be received and various outputs (display on a display unit, device control) may be performed.

Further, the program for realizing the POS system 1 and the POS terminal device 20 described above may be recorded on a computer-readable recording medium, and the program may be read and executed by the computer system. Note that the "computer system" herein includes hardware such as an OS and peripheral devices. Furthermore, "computer-readable recording media" refers to portable media such as USB (Universal Serial Bus) flash memory, SSD (Solid State Drive), flexible disks, magneto-optical disks, ROM, CD-ROM, and computer systems. Refers to a built-in storage device such as a hard disk. Furthermore, "computer-readable recording medium" refers to volatile memory (RAM) inside a computer system that serves as a server or client when a program is transmitted via a network such as the Internet or a communication line such as a telephone line. This also includes programs that are retained for a certain period of time. Further, the program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the "transmission medium" that transmits the program refers to a medium that has a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Moreover, the above-mentioned program may be for realizing a part of the above-mentioned functions. Furthermore, it may be a so-called difference file (difference program) that can realize the above-described functions in combination with a program already recorded in the computer system.
