In each block diagram, unless otherwise specified, each block does not represent a hardware unit configuration but a functional unit configuration.

[First embodiment]
[Functional configuration]
FIG. 1 is a block diagram conceptually showing the functional configuration of an information processing system 10 according to the first embodiment. The information processing system 10 includes a display processing unit 110 , a recall unit 120 , a status update unit 130 , a product registration device 20 and a settlement device 30 . In FIG. 1, the information processing system 10 is depicted as including one product registration device 20 and one checkout device 30, but the number of each device is not limited to this. The information processing system 10 includes at least one product registration device 20 and at least one checkout device 30 .

The product registration device 20 is used for processing for registering a product as an object of payment (hereinafter referred to as product registration processing). A user (clerk, etc.) of the product registration device 20 operates the product registration device 20 to perform product registration processing for each product purchased by a customer. Accounting information is generated by this registration process. The settlement information is information (information including the ID (Identifier) of the registered commodity, etc.) relating to the settlement processing of the commodity registered as the settlement target.

The settlement device 30 uses the settlement information registered in the commodity registration device 20 to execute the settlement processing for the product registered as the settlement object. Specifically, the settlement information is assigned to each settlement device 30 as follows. Methods for assigning settlement information to settlement devices 30 include a method for determining settlement devices 30 to which settlement information is to be allocated via a screen displayed on the product registration device 20 (hereinafter also referred to as a designation method), and a method for encoding settlement information. There is a method of allocating settlement information using portable media such as receipts with printed code symbols (one-dimensional or two-dimensional codes) and membership cards linked to settlement information (hereinafter also referred to as accounting ticket method). be. In the following description, it is assumed that any method can be used as a method for allocating settlement information. The settlement device 30 receives the allocated settlement information from the product registration device 20 or another device (server device), or acquires it by reading it from a portable medium, and performs settlement processing using the settlement information. . Settlement processing includes, for example, processing for accepting specified input of payment method (cash, credit, electronic money, etc.), processing for presenting the total amount to the customer, processing for accepting payment from the customer, processing for discharging change, It includes processing for issuing receipts.

The display processing unit 110 causes the product registration device 20 to display a screen in which a specific settlement device to which the allocated settlement information can be recalled can be selected from the settlement devices 30 to which the settlement information is allocated. display on the device. The display processing unit 110 determines a specific settlement device from among at least one settlement device 30, for example, based on whether information indicating the status of the settlement device indicates a recallable state. Further, the display processing unit 110 causes the display device for the store clerk to display a screen on which the specific settlement device can be selected, although a specific example will be described later.

Here, the "screen on which a specific settlement device can be selected" may be realized, for example, by controlling the active/inactive state of screen elements corresponding to each settlement device, or by recalling settlement information. It may be realized by including only screen elements corresponding to possible settlement devices on the screen, or if a settlement device that cannot recall settlement information is selected, control is performed so that recall of settlement information is not executed. It may be realized by Note that the display processing unit 110 attaches a predetermined mark to the settlement device 30 capable of recalling settlement information, or displays the settlement device 30 capable of recalling settlement information in a display mode (frame color, character color, etc.), The display mode of the settlement device 30 that cannot recall the settlement information may be changed. By doing so, it is possible to easily determine the settlement device 30 capable of recalling the settlement information based on the difference in the predetermined marks and displays. On such a screen, the clerk cannot select a settlement device to which settlement information that should not be called back is assigned. The recall unit 120 causes the product registration device using the screen to recall the settlement information assigned to the specific settlement device selected on the screen. The recall process is a process to make the settlement information assigned to the settlement device, that is, the settlement information whose contents have been fixed once, into a state that can be corrected by the commodity registration device. updates the status information of the selected specific clearing device to the state before the clearing information was assigned when the clearing information assigned to the selected specific clearing device is recalled.

[Action/effect]
As described above, in the present embodiment, a screen for selecting a settlement device (specific settlement device) capable of recalling the allocated settlement information is displayed on the display device for the store clerk. Also, recall processing of the settlement information assigned to the specific settlement device selected on the screen is executed by the product registration device using the screen. This recall process is a process of making the settlement information assigned to the settlement device, that is, the settlement information whose content has been fixed once, into a state that can be corrected by the commodity registration device. Thereby, the settlement information once transmitted to the settlement device can be corrected by the commodity registration device. Further, in the present embodiment, when the account settlement information assigned to the specific account settlement device is recalled, the status information of the specific account settlement device is updated to the state before the account settlement information was assigned. That is, it becomes possible to newly assign the settlement information to be processed to the specific settlement device whose settlement information has been recalled. As a result, the settlement device 30 can be prevented from being idle while the settlement information is being recalled, and the number of customers using the settlement device 30 per unit time can be increased.

The present embodiment will be described in further detail below.

[First example]
<Functional Configuration of Information Processing System 10>
Each functional configuration unit (in this embodiment, the display processing unit 110 and the recall unit 120) of the information processing system 10 is implemented by one or more information processing devices. For example, all of these functional components are implemented inside the product registration device 20 . FIG. 2 is a block diagram conceptually showing the functional configuration of the information processing system 10 in the first specific example of the first embodiment. As shown in FIG. 2, the product registration device 20 has the display processing unit 110 and recall unit 120 described above. In this example, the settlement device 30 also has an event detection unit 310 and a state update unit 130 .

The event detection unit 310 detects various events executed by the settlement device 30 . Here, the "event" means a process or operation of another device (for example, the product registration device 20) communicably connected to the settlement device 30, or an operation of the settlement device 30 by a customer of the store. means the processing and operation of the settlement device 30. In this example, the status update unit 130 updates the status information of the settlement device 30 stored in the predetermined storage unit according to the event detected by the event detection unit 310 . The predetermined storage unit is, for example, the storage unit of the product registration device 20, the storage unit of the settlement device 30, the storage unit of another device (not shown) communicably connected to the product registration device 20 and the settlement device 30, or the like. is. The display processing unit 110 can use the status information of the settlement device 30 stored in the storage unit to determine the settlement device 30 capable of recalling the settlement information. For example, the status information of the settlement device 30 is updated as follows.

First, when the settlement device 30 is in an initial state or in a state in which no settlement information to be processed is assigned to the settlement device 30, status information is set indicating a status in which the settlement information cannot be recalled. Then, when the event detection unit 310 detects an event for assigning settlement information (for example, an event for receiving settlement information from the product registration device 20, an event for reading settlement information from a medium, etc.), the state updating unit 130 detects the settlement device 30 is updated to indicate the recallable status of the settlement information. Further, when the event detection unit 310 detects a completion event of the settlement process executed by the settlement device 30, the status update unit 130 changes the status information of the settlement device 30 to a status where the settlement information cannot be recalled. Update to the status information shown. Specific examples of the settlement process completion event include, for example, a button press event for confirming the amount charged or input to the settlement apparatus 30, a receipt issuance event for printing the contents of the settlement process, and a final event in a series of processes. A display event of a screen to be used can be cited.

Here, the event detected by the event detection unit 310 is an event other than an event indicating the completion of the settlement process, and an event to which status information indicating a status in which the settlement information cannot be recalled should be set (hereinafter referred to as Also known as a specific event) is included. A particular event may be determined, for example, based on whether recalling the settlement information after the occurrence of the particular event may cause any inconvenience. For example, while the customer is operating the payment device 30, there is a possibility that the payment information is erroneously recalled. Also, for example, if the customer has already put money into the settlement device 30, it may take additional time to deal with the money that has already been put in. Before the customer of the store operates the settlement device 30, the settlement device 30 has not started the settlement processing, so even if the settlement information is recalled from the settlement device 30, the above-described inconvenience may occur. no. Therefore, as an example, an event in which it can be determined that a customer of a store has operated a settlement device to start settlement processing can be used as the specific event. Specifically, the specific event in this case is a selection input event of a payment method (cash, electronic money, credit card, etc.), or a payment reception event by the selected payment method. However, the specific event that determines the specific event is not limited to the examples given here. When the event detection unit 310 detects this specific event, the status update unit 130 updates the status information of the settlement device 30 to status information indicating a status in which the settlement information cannot be recalled. Information identifying these specific events (for example, a table defining event IDs of specific events, flag information, etc.) is set in advance in, for example, the event detection unit 310, and the event detection unit 310 identifies the detected event. Whether or not it is an event can be determined using this information.

Even after the specific event is detected, for example, if the event detection unit 310 detects an event that cancels the specific event, the status update unit 130 updates the status information of the settlement device 30 to the settlement information. It can return status information that indicates the status that recall is possible. For example, in the above example, when the event detection unit 310 detects an event of selecting a payment method and then further detects an event of canceling the input of the selection of the payment method, the status update unit 130 updates the status information of the settlement device 30 can be updated with status information indicating a recallable status of the billing information.

Connected.

The hardware configuration of the information processing system 10 shown in FIG. 3 is merely an example, and the hardware configuration of the information processing system 10 is not limited to the configuration shown in FIG.

<Operation example>
An operation example of the information processing system 10 in this specific example will be described below. FIG. 4 is a sequence diagram showing the flow of processing of the information processing system 10 in the first specific example of the first embodiment.

The display processing unit 110 receives a screen display operation by the store clerk (S102). For example, a screen as shown in FIG. 5 is displayed on the display device for the store clerk in order to accept the screen display operation. FIG. 5 is a diagram showing an example of a screen displayed on a display device for salesclerks. In the example of FIG. 5 , the operation of pressing the screen display button (settlement device button) 50 provided on the screen by the store clerk is the screen display operation accepted by the display processing unit 110 .

When receiving the screen display operation, the display processing unit 110 requests the settlement device 30 to transmit the status information (S104). The settlement device 30, upon receiving the request of S104, transmits the status information stored in the storage unit of the settlement device 30 to the product registration device 20 (S106). If there is another device (not shown) that collects and manages the status information of each settlement device 30, the display processing unit 110 may request the other device to transmit the status information. . Further, when the product registration device 20 is periodically notified of the status information of each settlement device 30 and the product registration device 20 stores the status information, the display processing unit 110 performs A process of reading the status information stored in the product registration device 20 may be executed.

Then, the display processing unit 110 determines the settlement device 30 (specific settlement device) holding the recallable settlement information based on the acquired status information of each settlement device 30 (S108). Then, the display processing unit 110 uses the determination result of S108 to display a screen for recalling the settlement information on the display device for the store clerk who operates the product registration device 20 (S110).

A specific flow of the display processing unit 110 causing the display device to display the screen for recalling the settlement information will be described with reference to FIGS. 6 and 7. FIG.

FIG. 6 is a diagram showing an example of status information of each settlement device 30 acquired by the display processing unit 110 in S104. In FIG. 6, the status information of the four settlement devices 30 (settlement device 1, settlement device 2, settlement device 3, and settlement device 4) are respectively "waiting", "can be called back", "in use", A case of "recallable" is exemplified. Here, the "waiting" status information indicates a state in which settlement information to be processed is not assigned to the settlement device. Further, the status information of "recallable" indicates a state in which settlement information to be processed is assigned to the settlement device and the settlement information can be recalled. The "in use" status information indicates that the settlement information to be processed is assigned to the settlement device, and the customer has started to operate the settlement device. Note that the status information is not limited to the examples given here. Status information such as "waiting," "callable," and "busy" may have different definitions than those exemplified here. Also, status information indicating other states may be further defined.

Based on the status information shown in FIG. 6, the display processing unit 110 determines "settlement device 2" and "settlement device 4" as settlement devices holding recallable settlement information. Then, the display processing unit 110 causes the display device to display a screen as shown in FIG. 7, for example, based on the determination result. FIG. 7 is a diagram showing an example of a screen for recalling settlement information that the display processing unit 110 displays on the display device. In the screen illustrated in FIG. 7, the recall button 70 is in a state in which only the buttons for "settlement device 2" and "settlement device 4" can be pressed (represented by solid lines in FIG. 7), and "settlement device 1” and “settlement device 3” buttons cannot be pressed (represented by dotted lines in FIG. 7). Note that the screen in FIG. 7 is merely an example, and the screen that the display processing unit 110 causes the display device to display is not limited to the example in FIG. For example, the display processing unit 110 puts all the recall buttons 70 in a state in which they can be pressed, and displays the settlement information when the recall button 70 of "settlement device 1" or "settlement device 3" is pressed. A screen may be displayed on the display device to restrict the recall of the settlement information by displaying a message to the effect that recall is not possible. Further, for example, the display processing unit 110 may cause the display device to display a screen including only screen elements related to "settlement device 2" and "settlement device 4".

Returning to FIG. 4, the recall unit 120 accepts the selection input operation of the settlement device by the clerk via the screen as shown in FIG. 7 (S112). Then, the recall unit 120 requests the settlement device 30 selected in S112 to transmit the settlement information (S114). Note that the status information of the settlement device 30 is updated by, for example, the customer operating the settlement device 30 during the period from when the screen is displayed in the processing of S110 to when the operation by the clerk is accepted in the processing of S112. It is also possible. Therefore, the settlement device 30 that has received this transmission request determines whether or not the current status information is "recallable" indicating a state in which recall is possible (S116).

Here, the product registration device 20 may include a request to output that the recall process is being attempted on the settlement device 30 in the transmission request of S114. For example, the product registration device 20 may further include a request to display a pop-up screen containing a predetermined message ("Recalling the transaction. Please wait for a while.") on the display unit of the settlement device 30. With such an output, the customer using the settlement device 30 can easily recognize that the recall process is currently being tried. This output ends, for example, when the recall process is performed normally, or when an error occurs, as will be described later.

If the status information is "recallable" (S116: YES), the settlement device 30 transmits settlement information to the product registration device 20 (S118). As a result, the settlement information once transmitted to the settlement device 30 is recalled to the commodity registration device 20 . When the product registration device 20 acquires the settlement information called back from the settlement device 30, the display processing unit 110 causes the display unit to display a predetermined screen (S120).

Here, the purpose of recalling the settlement information from the settlement device 30 includes, for example, the following examples. As an example, it is conceivable that the purpose is to change the content of a product that has already been registered as an object of payment by recalling the settlement information to the product registration device 20 that performs the product registration process. Another possible purpose is to pay at least part of the product price by a payment method not handled by the settlement device 30 (for example, payment by cash voucher). Therefore, the display processing unit 110 preferably displays either the first screen (eg, FIG. 8) for changing the details of the product to be settled, or the second screen (eg, FIG. 9) for registering the payment details. One of them is displayed on the display device as a predetermined screen. As a result, the effect of improving the efficiency and convenience of the work performed by the store clerk can be expected.

FIG. 8 is a diagram showing an example of the first screen that the display processing unit 110 causes the display device to display. As shown in FIG. 8, the display processing unit 110 causes the display device to display a screen displaying a list of products registered as products to be settled using the recalled payment information. On this screen, the store clerk can change the product, change the number of products, additionally register the product, delete the product, and modify information regarding discounts and discounts. FIG. 9 is a diagram showing an example of the second screen that the display processing unit 110 causes the display device to display. On the screen of FIG. 9, the amounts of various payment methods available to the customer are entered. The store clerk inputs the amount of cash, coupons, etc. received from the customer to this screen via various input devices.

Note that the display processing unit 110 acquires information (callback purpose information) indicating the purpose of recalling the settlement information from the settlement device, and selects one of the first screen and the second screen for the purpose indicated by the recall purpose information. The corresponding screen may be configured to be displayed on the display device. Specifically, the display processing unit 110 further displays, for example, a screen as shown in FIG. 10 on the display device. FIG. 10 is a diagram showing an example of a screen on which recall purpose information can be designated. The screen of FIG. 10 includes a screen element 80 for displaying the first screen (eg, FIG. 8) on the display device and a screen element 82 for displaying the second screen (eg, FIG. 9) on the display device. including. The store clerk, for example, asks the customer about the purpose of recalling the settlement information, and selects a screen element that meets the purpose. Then, the recall purpose information corresponding to the screen element selected here is displayed in the display processing unit 110, and the screen (the screen of FIG. 8 or the screen of FIG. 9) corresponding to the recall purpose information is displayed on the display device. be. However, the screen of FIG. 10 is only an example, and the method of acquiring recall purpose information is not limited to this example.

Further, the settlement device 30 may delete the settlement information of the settlement device 30 after the recall processing of the settlement information is executed (S122). In this case, the event detection unit 310 detects a deletion event of settlement information. Then, the event detection unit 310 notifies the state update unit 130 that the event of deleting the payment information has been detected. In response to this notification, the status update unit 130 updates the status information of the settlement device to "waiting", that is, the state in which settlement information is not held. In other words, the settlement device 30 whose settlement information is recalled returns to the state before the settlement information to be processed was assigned. The settlement device 30 in this state can execute new settlement processing using the new settlement information by allocating the new settlement information. As a result, the settlement device 30 can be prevented from being idle while the settlement information is being recalled, and the number of customers using the settlement device 30 per unit time can be increased.

On the other hand, if the status information is not “recallable” (S116: NO), the settlement device 30 transmits an error notification to the product registration device 20. FIG. When the product registration device 20 acquires the error notification, the display processing unit 110 causes the display unit to display a predetermined screen such as a message screen indicating that the recall has failed (S120). In this case, the settlement device 30 does not execute the settlement information deletion process (S122).

Note that the hardware configuration of the information processing system 10 shown in FIG. 12 is merely an example, and the hardware configuration of the information processing system 10 is not limited to the configuration shown in FIG. 12 .

<Operation example>
An operation example of the information processing system 10 in this specific example will be described below. FIG. 13 is a sequence diagram showing the flow of processing of the information processing system 10 in the second specific example of the first embodiment. In the following description, the same reference numerals are assigned to the same processes as in the first specific example, and new reference numerals are assigned to the different processes from the first specific example.

The display processing unit 110 receives a screen display operation by the store clerk (S102). For example, a screen as shown in FIG. 5 is displayed on the display device for the store clerk in order to accept the screen display operation. In the example of FIG. 5 , the operation of pressing the screen display button (settlement device button) 50 provided on the screen by the store clerk is the screen display operation accepted by the display processing unit 110 .

Upon receiving the screen display operation, the display processing unit 110 requests the server device 40 to transmit status information (S202). When the server device 40 receives the request of S202, it transmits the status information of the settlement device 30 collected from each settlement device 30, which is stored in the storage unit of the server device 40, to the product registration device 20 (S204). If there is another device (not shown) that collects and manages the status information of each settlement device 30, the display processing unit 110 may request the other device to transmit the status information. . Further, when the status information of each settlement device 30 is periodically notified from the server device 40 to the product registration device 20 and the product registration device 20 stores the status information, the display processing unit 110 performs steps S202 and S204. The status information stored in the product registration device 20 may be read out instead of the process of .

Then, the display processing unit 110 determines the settlement device 30 (specific settlement device) holding the recallable settlement information based on the acquired status information of each settlement device 30 (S108). Then, the display processing unit 110 uses the determination result of S108 to display, for example, a screen for recalling the settlement information as shown in FIG. ).

Then, the product registration device 20 receives a selection input operation of the checkout device by the store clerk via a screen as shown in FIG. 7 (S110). When a selection input operation is received on the screen, the product registration device 20 receives information identifying the selected settlement device (for example, a settlement device ID unique to each settlement device) and information identifying the product registration device 20. (for example, a product registration device ID unique to each product registration device, etc.), and a request to execute the recall processing of the settlement information is transmitted to the server device 40 (S206). Then, the recall unit 120 of the server device 40 requests the settlement device 30 corresponding to the settlement device ID acquired in S206 to transmit the settlement information (S208). Note that the status information of the settlement device 30 is updated by, for example, the customer operating the settlement device 30 during the period from when the screen is displayed in the processing of S110 to when the operation by the clerk is accepted in the processing of S112. It is also possible. Therefore, the settlement device 30 that has received this transmission request determines whether or not the current status information is "recallable" indicating a state in which recall is possible (S116).

Here, the product registration device 20 may include a request to output that recall processing is attempted on the settlement device 30 in the transmission request of S206. For example, the product registration device 20 may further include a request to display a pop-up screen containing a predetermined message ("Recalling the transaction. Please wait for a while.") on the display unit of the settlement device 30. With such an output, the customer using the settlement device 30 can easily recognize that the recall process is currently being tried. This output ends, for example, when the recall process is performed normally, or when an error occurs, as will be described later.

When the status information is "recallable" (S116: YES), the settlement device 30 transmits the settlement information to the server device 40 in a state in which its own settlement device ID is linked (S210). When the recall unit 120 of the server device 40 acquires the settlement information associated with the settlement device ID, it specifies the product registration device 20 to which the settlement information should be transmitted (S212). Specifically, the recall unit 120 of the server device 40 acquires in S210 based on the correspondence relationship between the settlement device ID and the product registration device ID in the execution request acquired in S206 and the settlement device ID acquired in S210. The product registration device 20 to which the calculated settlement information should be transmitted is specified. Then, the recall unit 120 of the server device 40 transmits the settlement information acquired in S210 to the specified product registration device 20 (S214). As a result, the settlement information once transmitted to the settlement device 30 is recalled to the commodity registration device 20 . The server device 40 may further transmit the product registration device ID in S208, and in this case, the settlement device 30 may directly transmit the settlement information to the product registration device 20 identified by the product registration device ID. . In this case, the processing of S212 and S214 becomes unnecessary.

When the product registration device 20 acquires the settlement information called back from the settlement device 30, the display processing unit 110 displays a predetermined screen (the screen in FIG. 8 or the screen in FIG. 9) as described in the first specific example. It is displayed on the display unit (S120).

Further, the settlement device 30 may delete the settlement information after the recall of the settlement information is executed (S122). In this case, the event detection unit 310, in response to detection of the settlement information deletion event, notifies the state updating unit 130 of the detection notification of the event or the notification of updating the status information of the settlement device to "waiting". Send to Then, the status update unit 130 updates the status information of the notified settlement device to "waiting". In other words, the settlement device 30 whose settlement information is recalled returns to the state before the settlement information to be processed was assigned. The settlement device 30 in this state can execute new settlement processing using the new settlement information by allocating the new settlement information. As a result, the settlement device 30 can be prevented from being idle while the settlement information is being recalled, and the number of customers who use the settlement device 30 per unit time can be increased.

On the other hand, if the status information is not "recallable" (S116: NO), the settlement device 30 transmits an error notification to the product registration device 20 with its own settlement device ID linked (S216). When the server device 40 acquires the error notification associated with the settlement device ID, the server device 40 specifies the product registration device 20 to which the settlement information should be transmitted (S218). Specifically, the server device 40 transmits the error notification acquired in S216 based on the correspondence relationship between the settlement device ID and the product registration device ID in the execution request acquired in S206 and the settlement device ID acquired in S210. The product registration device 20 to be registered is specified. Then, the server device 40 transmits the error notification acquired in S218 to the specified product registration device 20 (S220). When the product registration device 20 acquires the error notification, the display processing unit 110 causes the display unit to display a predetermined screen such as a message screen indicating that the recall has failed (S120). The server device 40 may further transmit the product registration device ID in S208, and in this case, the settlement device 30 may directly transmit an error notification to the product registration device 20 identified by the product registration device ID. . In this case, the processing of S218 and S220 becomes unnecessary. Further, in this case, the settlement device 30 does not execute the settlement information deletion process (S122).

As described above by exemplifying each operation example, only the settlement information that can be recalled from the settlement device 30 can be recalled to the product registration device 20 . Further, the settlement device 30 whose settlement information is recalled returns to the state before the settlement information was assigned, and can execute new settlement processing by assigning new settlement information. As a result, the number of customers who use the settlement device 30 per unit time can be increased.
