The reserved product of "pseudo-scan input" is a product in which the customer tries to have the customer terminal device 50 read the code of the product, but the customer terminal device 50 cannot normally read the code.

As a specific example, the "pseudo-scan input" corresponds to a situation in which the product is included in the imaging range of the imaging unit 506, but the product code is not included in the imaging range of the imaging unit 506.
Further, the "pseudo-scan input" corresponds to a situation in which the product is placed in the imaging range of the imaging unit 506, but the portion without the code is imaged.
Further, the "pseudo-scan input" corresponds to a situation in which the product is placed in the imaging range of the imaging unit 506 with the cord portion hidden by a finger or the like.
Further, in the "pseudo-scan input", the product code is imaged by the image pickup unit 506, but the product is passed through the image pickup range of the image pickup unit 506 at a speed at which the customer terminal device 50 cannot read the code. Situations apply.

The classification of the reserved goods of the classification number 4 is "non-scan input". The "non-scanning" pending product is a product that has been placed in the shopping cart without performing an operation of positioning the product in the imaging range of the imaging unit 506.
This non-scanning can occur, for example, when the customer terminal device 50 is fixedly attached to the shopping cart so that the inside of the shopping cart placed on the shopping cart can be imaged. For example, when the customer terminal device 50 determines that the product has been put in the shopping cart even though the code scan of the product has not been performed based on the captured image, the non-scan input is performed. It can be determined that it has been done.

The classification of the reserved product of the classification number 5 is "age confirmation product". An "age confirmation product" is a product that requires a clerk to confirm the age of a customer for sale, such as alcohol and cigarettes.

The classification of the reserved goods of classification number 6 is "pharmaceutical products". A "pharmaceutical product" is a product for which a qualified pharmacist or the like needs to ask the purchaser for confirmation.

The classification of the reserved product of the classification number 7 is "security tag product". A "security tag product" is a product that requires a clerk to remove the security tag from the product at the time of sale because the security tag is attached.

The classification of the reserved goods of the classification number 8 is "cancelled goods". The "cancelled product" is a product that has been registered once but has been canceled by the customer's cancel operation on the customer terminal device 50. The "cancelled product" is, for example, made to be picked up by a clerk from a customer at the time of payment.

The product master is stored, for example, by the management device 10. The product master stores product information for each product sold at the store. The product information corresponding to one product includes a plurality of predetermined information items such as a product code and a product name.
The transaction management device 60 stores the product master acquired from the management device 10. The transaction management device 60 uses the stored product master for processing related to product registration and the like.

The product code of the reserved product corresponding to the category number 1 "NON-FILE" was acquired by the code scan according to the product registration operation, but the product information associated with the acquired product code is registered in the product master. It has not been. Therefore, it is not specified which of the products registered in the product master is the reserved product corresponding to the "NON-FILE" of the classification number 1.
The reserved products that fall under any of the three categories of "reading NG", "pseudo scan input", and "non-scan input" of the classification numbers 2 to 4 are the product codes as a result of the code scan according to the product registration operation. Failed to get. Therefore, the reserved product that falls under any of the three categories of "reading NG", "pseudo scan input", and "non-scan input" of the classification numbers 2 to 4 is any of the products registered in the product master. It is not specified whether it is.

Among the classification numbers 1 to 7, there are no pending products that fall under any of the four categories of classification numbers 1 to 4, "NON-FILE", "reading NG", "pseudo scan input", and "non-scan input". It is a specific product. The unspecified product is, for example, a product whose registration result is incomplete because it is not specified which of the products is registered in the product master.
Unspecified products include code-acquired products whose product code has been acquired by product registration operation, such as "NON-FILE" of classification number 1, "reading NG" of classification numbers 2 to 4, and "pseudo-scan input". , "Non-scan input", etc., are divided into products for which the product code has not been acquired by the product registration operation and products for which the product code has not been acquired.

In addition, the transaction management device 60 replaces or additionally stores the cart information in the storage unit in the own device, or a part of the cart information or a part of the cart information in another device (a file server or the like accessible to the transaction management device 60). You may memorize everything.

[Example of basic processing procedure for self-operation]
The sequence diagram of FIG. 10 shows an example of a processing procedure executed by the customer terminal device 50, the settlement device 40, and the transaction management device 60 corresponding to the accounting of one transaction in self-operation. Specifically, in the process of the figure, the customer registers the product to be purchased from the products displayed in the store, and the customer terminal device 50 and the payment are completed until the payment for the registered product is completed. An example of the processing of the apparatus 40 and the transaction management apparatus 60 is shown.
Further, in the explanation of the figure, a case where the customer terminal device 50 is a personal terminal 50A will be taken as an example.

Step S1: The customer terminal device 50 acquires information for specifying a store (store-specific information). For example, a two-dimensional code indicating a store identification code for identifying the store is displayed near the entrance of the store (output the two-dimensional code on the display screen, affix a medium on which the two-dimensional code is printed, etc.) and visit the store. The customer terminal device 50 may acquire the store identification information by scanning (reading) the two-dimensional code with the customer terminal device 50. When a customer who visits the store activates the shopping application, a screen instructing the customer to scan the two-dimensional code may be displayed as the activation screen, or the customer who visits the store may use the customer terminal device 50 to display the two-dimensional code. When scanning, a shopping application may be activated, and a screen notifying the customer that the customer is connected to the transaction management device 60 may be displayed as an activation screen.

Further, for example, since the store is specified by the location, the customer who visits the store may acquire the location information (GPS information) by the customer terminal device 50 at the store (that is, the location information of the store is acquired as the store identification information). May be). When a customer who visits the store activates the shopping application, the location information may be acquired and a screen for notifying the customer that the customer is connected to the transaction management device 60 may be displayed as the activation screen. If a plurality of stores are detected from the location information and cannot be specified as one, a selection screen may be displayed and the customer may be made to select. Alternatively, the mode may be switched to forcibly acquiring the two-dimensional code.
Further, for example, the customer terminal device 50 may acquire store identification information by communicating with a beacon provided at a predetermined place in the store.

FIG. 11A shows an example of a shopping application startup screen displayed on the display unit 504 of the customer terminal device 50. The store name is displayed on the startup screen in the figure. This store name is displayed based on the store identification information acquired in step S1.
When starting product registration for shopping, the customer operates the transaction start instruction button BT10 arranged on the start screen.
In response to the operation of the transaction start instruction button BT10, the customer terminal device 50 transmits a transaction start request including the acquired store identification information and customer identification information to the transaction management device 60. The transaction start request may be transmitted in response to the customer's operation on the customer terminal device 50 as described above, or the transmission is executed in response to the acquisition of the store specific information without accepting any particular operation. You may do so.
Regarding the customer identification information, the information entered in the name field of the registration form using the customer terminal device 50 at the time of customer registration (when downloading or installing the shopping application on the customer terminal device 50) is the transaction management device 60. Although it may be stored in the customer information, it may be stored in the storage unit of the customer terminal device 50 in addition to the transaction management device 60. If a store is specified (when the product registration initial screen described later is acquired), the store name of the store, the service being implemented (flyer information distributed on that day), and available coupon information will be displayed. It may be displayed on a screen (a screen different from the product registration initial screen or the product registration initial screen). Information on services and coupons may be acquired from the transaction management device 60 as screen information, for example.
The transaction start request may include application identification information uniquely indicating the shopping application instead of the customer identification information.

Further, the destination information (address of the transaction management device 60) is also acquired at the time of customer registration (when the shopping application is downloaded or installed on the customer terminal device 50) and stored in the storage unit of the customer terminal device 50. You may leave it. In the case of scanning the two-dimensional code, in addition to the store identification information, the destination information is also converted into a two-dimensional code, and the customer terminal device 50 scans the two-dimensional code to scan the customer terminal. The device 50 may acquire the destination information as well as the store identification information.

Step S2: The transaction management device 60, which has received the customer identification information and the store identification information as a transaction start request from the customer terminal device 50, generates the cart information of the transaction. In the initial state of the cart information, the cart identification information, the transaction start date and time, and the customer identification information are stored, but since it is before the actual transaction (product registration) starts, other information (transaction end). The date and time, product information (registered product information, pending product information), etc.) are not stored.

As described above, since the transaction management device 60 stores the store information as shown in FIG. 7 (B), the transaction management device 60 receives the store identification information as a transaction start request from the customer terminal device 50 (also receives the customer identification information). However, if the received store identification information is a two-dimensional code, the store identification information is acquired by referring to the store identification information 1, and the received store identification information is the location information (GPS information). If there is, the store identification information is acquired by referring to the store identification information 2. If the store identification information received from the customer terminal device 50 is a two-dimensional code of the store identification information, the transaction management device 60 may acquire the store identification information as it is.

That is, the transaction management device 60, which has received the customer identification information and the store identification information as a transaction start request from the customer terminal device 50, acquires the store identification information from the store identification information received from the customer terminal device 50, and further sets the current date. Acquire, issue (number) the serial number, combine the store identification information with the current date and the serial number, and store it as the cart identification information in the cart information. Further, the transaction management device 60, which has received the store identification information and the customer identification information as a transaction start request from the customer terminal device 50, acquires the current date and time and stores it as the transaction start date and time (generation date and time) in the cart information. Further, the transaction management device 60, which has received the store identification information and the customer identification information as a transaction start request from the customer terminal device 50, stores the customer identification information received from the customer terminal device 50 as the customer identification information in the cart information.

Step S3: The transaction management device 60 that generated the cart information of the transaction generates the product registration initial screen information (screen information of the product registration screen that is the initial screen) and transmits it to the customer terminal device 50. Specifically, the transaction management device 60 generates, for example, product registration initial screen information, and transmits the generated product registration initial screen information to the customer terminal device 50 together with the cart identification information.

Step S4: The customer terminal device 50 that has received the cart identification information and the product registration initial screen information from the transaction management device 60 stores the cart identification information and displays the registration screen on the display unit. Specifically, the customer terminal device 50 displays a product registration initial screen as shown in FIG. 11B, for example.

Step S5: By the operation of the customer, the customer terminal device 50 scans the bar code attached to the product and reads the product code. In the figure, it is assumed that the barcode scan was successful. Steps S5 to S9 are repeatedly executed every time the barcode attached to the product is scanned.

The customer terminal device 50 that has acquired the barcode transmits the cart identification information and the product registration information including the product code obtained by scanning to the transaction management device 60.

Step S6: The transaction management device 60 that has received the product registration information (cart identification information and product code) from the customer terminal device 50 identifies the cart information of the transaction from the cart identification information included in the received product registration information. do.

Step S7: The transaction management device 60 updates the product data in the specified cart information. Specifically, when the received product registration information includes a product code as an N item, the transaction management device 60 registers the product code in the specified cart information (registered product N). ), The product name and price corresponding to the product code are acquired from the product information, and stored as the product and price of the registered product information (registered product N). Further, the transaction management device 60 updates the registered product information (total) in the specified cart information.

Step S8: The transaction management device 60 that has updated the product data in the cart information generates product registration update screen information (screen information of the product registration screen that is the update screen to which the registered product is added), and the customer terminal device 50. Send to. Specifically, the transaction management device 60 displays a product registration update screen to which a list item of the product registered this time is added in the registered product list, as shown in FIG. 11C in the customer terminal device 50, for example. The product registration update screen information is generated, and the generated product registration update screen information is transmitted to the customer terminal device 50 together with the cart identification information.

The product registration screen (product registration update screen) shown in FIG. 11C is displayed on the customer terminal device 50 after "○○ bread" is registered as a product of three items. That is, when the transaction management device 60 stores "OO yogurt" as one item in the cart information, the transaction management device 60 generates and generates product registration update screen information such that "OO yogurt" is displayed on the customer terminal device 50. When the product registration update screen information is sent to the customer terminal device 50 together with the cart identification information and "○○ chocolate" is stored in the cart as two items, "○○ yogurt" and "○○ chocolate" are stored in the customer terminal device 50. Is generated, and the generated product registration update screen information is transmitted to the customer terminal device 50 together with the cart identification information, and "○○ bread" is stored in the cart information as three items. At that time, as shown in FIG. 11 (C), the product registration update screen information such that "○○ yogurt", "○○ chocolate", and "○○ bread" are displayed on the customer terminal device 50 is generated. , The generated product registration update screen information is transmitted to the customer terminal device 50 together with the cart identification information.

In addition, depending on the registration of one product, the registered product presentation screen WD1 for presenting the product registered this time may be displayed, for example, as shown in FIG. 12 (A). In addition, on the registered product presentation screen WD1 in the figure, the "Yes" button BT1 and the "No" button confirm with the customer whether or not to eat or drink by eating in, depending on whether the target product supports eat-in. An example in which BT2 and BT2 are arranged is shown. In this case, the price of the product is calculated so that the consumption tax rate for the target product differs depending on whether the "Yes" button BT1 is operated or the "No" button BT2 is operated. become.

Step S9: The customer terminal device 50 that has received the cart identification information and the product registration update screen information from the transaction management device 60 adds the product to the registration screen. Specifically, the customer terminal device 50 displays a product registration update screen as shown in FIG. 11C, for example. As described above, the product registration screen (product registration update screen) shown in FIG. 11C is displayed on the customer terminal device 50 after "○○ bread" is registered as a product of three items. Is.

Step S10: The customer terminal device 50 accepts a settlement transition instruction operation as a customer operation. For example, the touch of the "Proceed to checkout" button shown in FIG. 11C is accepted.

Step S11: The customer terminal device 50 that has received the settlement transition instruction operation generates a two-dimensional code. That is, the customer terminal device 50 two-dimensionally encodes the information (for example, cart identification information) required for executing the settlement process for the purchased product by the customer terminal device 50. The customer terminal device 50 that generated the two-dimensional code displays the generated two-dimensional code on the display unit. For example, a code display screen in which a two-dimensional code as shown in FIG. 11D is arranged is displayed on the display unit.

Step S12: The checkout device 40 scans (reads) the two-dimensional code displayed on the display unit of the customer terminal device 50. For example, the settlement device 40 scans the two-dimensional code displayed on the display unit of the customer terminal device 50 directed by the customer within the recognition range by the customer side scanner unit 406.

Step S13: The settlement device 40 that has read the two-dimensional code displayed on the display unit of the customer terminal device 50 requests the transaction management device 60 to calculate the subtotal amount. For example, the settlement device 40 transmits a calculation request (small calculation output request information) requesting the calculation of the subtotal amount to the transaction management device 60 together with the cart identification information acquired from the two-dimensional code.

Step S14: The transaction management device 60, which has received the cart identification information and the subcalculation request information from the customer terminal device 50, identifies the cart information of the transaction from the cart identification information.

Step S15: The transaction management device 60 that specifies the cart calculates the subtotal amount by using the information such as the price in the registered product information included in the cart information corresponding to the specified cart information.

Step S16: The transaction management device 60 that has calculated the subtotal amount updates the cart information (stores the subtotal amount (calculated subtotal amount)), and at the same time, the subtotal information indicating the calculated subtotal amount is sent to the settlement device 40 together with the cart identification information. Send.

Step S17: The settlement device 40, which has received the cart identification information and the subtotal information from the transaction management device 60, displays the subtotal amount as shown in FIG. 12B on the customer side display unit 405.

Step S18: The settlement device 40 displaying the subtotal amount on the customer side display unit 405 executes payment (settlement). Specifically, the settlement device 40 accepts the selection of the payment type. In the case of cash, the deposit is accepted, the amount of change is calculated, and if there is change, the change is released and a receipt is issued. Further, when the settlement is completed, the settlement device 40 transmits the settlement completion information together with the cart information to the transaction management device 60, and the transaction management device 60 stores the transaction end date and time (settlement date and time) of the cart.

The customer terminal device 50 transmits the product code to the transaction management device 60 after scanning the product (S5), but the product scanned in the store (the store when the product registration initial screen is displayed after visiting the store). You may not send the product code for products other than (for example, products that have been moved to another store and scanned). For example, the customer terminal device 50 acquires and stores location information (GPS information) when visiting a store (or when displaying a product registration initial screen). Further, the customer terminal device 50 acquires location information when scanning individual products, and obtains the location information acquired when scanning the products and the location information acquired when visiting the store (or when displaying the product registration initial screen). Compare. Then, the customer terminal device 50 permits transmission of the product code of the product to the transaction management device 60 when the two match (or substantially match), and when the two do not match (or substantially match), the said product code. The transmission of the product code of the product to the transaction management device 60 may be prohibited.
This makes it possible to prevent inappropriate product registration (for example, product registration for a cart generated in another store or the like).

When the payment device 40 prohibits the transmission of the product code as described above, the payment device 40 displays an error message (for example, "Registration is not possible because it is not in the XX store") on the customer side display unit 405 after scanning the product. It may be displayed. Further, the settlement device 40 may display the above message on the clerk side display unit 410 in place of or in addition to the customer side display unit 405.

Further, the settlement device 40 requests the transaction management device 60 to calculate the subtotal amount after reading the two-dimensional code displayed on the display unit of the customer terminal device 50 (S13), but the product scanned in the store. It is also possible not to request the calculation of the subtotal amount for products other than (for example, products scanned at other stores). For example, the settlement device 40 may refer to the store identification information of the store (the store identification information of the store may be stored and referred to in the self-payment device 40, or may be stored in another accessible device. (You may refer to the store identification information), the cart identification information obtained from the two-dimensional code when the two-dimensional code displayed on the display unit of the customer terminal device 50 is read, and the store identification of the store. Compare with information. Then, when the store identification information included in the cart identification information includes the store identification information of the store, the settlement device 40 permits the request for calculation of the subtotal amount and includes the store identification information of the store. If it is not configured, the request to calculate the subtotal amount may be prohibited.
This makes it possible to prevent inappropriate settlement (for example, settlement of a product registered as a product at another store or the like).

When the payment device 40 prohibits the request for the subtotal amount as described above, the payment device 40 issues an error message (for example, "cannot be settled because it includes products other than XX stores") after reading the two-dimensional code. It may be displayed on the display unit 405. Further, the settlement device 40 may display the above message on the clerk side display unit 410 in place of or in addition to the customer side display unit 405.

In the example of the processing procedure of FIG. 10, the transaction management device 60 is configured to calculate the subtotal amount. However, for example, the settlement device 40 may acquire cart information from the transaction management device 60 and calculate the subtotal amount based on the acquired cart information. Alternatively, the transaction management device 60 sends cart information to the management device 10 to request the calculation of the subtotal amount, the management device 10 calculates the subtotal amount using the received cart information, and the calculated subtotal amount is used. , It may be transmitted to the settlement device 40 via the transaction management device 60.

The transaction management device 60 confirms the cancellation status of the customer's products so far based on the customer information and the cart information of the corresponding customer at the time of settlement processing, and determines whether or not to give a warning against fraud. You can do it. When it is determined that the warning should be given, the transaction management device 60 may cause, for example, the settlement device 40 to execute the notification for the warning.

Further, the transaction management device 60 determines whether or not the reserved product is included in the product information included in the cart information at the time of the settlement process, and if the reserved product is included, the transaction management device 60 holds the product in the settlement device 40. You may request correction instructions for the product. Upon receiving the request for the correction instruction of the reserved product, the settlement device 40 displays to notify that there is a reserved product, as shown in FIG. 12 (C). The clerk who confirms the notification performs operations such as inputting the price corresponding to the reserved product and canceling the reserved product as the cancellation (correction) of the reserved product.

In the processing procedure example shown in FIG. 10, each time the product code information is scanned by the customer terminal device 50 and the product code is read, the product code read by the customer terminal device 50 is transmitted to the transaction management device 60. It is made to do. That is, in the processing procedure example of FIG. 10, each time the product registration process corresponding to the reading of the product code is executed by the customer terminal device 50, the product registration information including the product code obtained by the product registration process is traded. It is transmitted to the management device 60. In this case, the transaction management device 60 is included in the product registration information in the cart information specified by the cart identification information included in the product registration information each time the product registration information is received from the customer terminal device 50. Store the registered product information corresponding to the product code.

In the present embodiment, the product registration information may be processed by the following procedure different from that in FIG.
That is, the customer terminal device 50 stores the product code acquired by the product registration process in one transaction without transmitting it until the operation of the settlement transition instruction is performed. Then, the customer terminal device 50 is configured to transmit the product registration information including one or more product codes stored so far to the transaction management device 60 in response to the operation of the settlement transition instruction. To. The transaction management device 60 stores the registered product information corresponding to one or more product codes included in the product registration information in the cart information specified by the cart identification information included in the received product registration information. do. That is, the customer terminal device 50 in the present embodiment is configured to collectively transmit the product registration information in response to the settlement transition instruction.
In this way, when the customer terminal device 50 collectively transmits the product registration information in response to the settlement transition instruction, the number of communications between the customer terminal device 50 and the transaction management device 60 is reduced. Therefore, it is possible to reduce the processing load and the power consumption in the customer terminal device 50. Further, it is possible to reduce the amount of traffic between the customer terminal device 50 and the transaction management device 60.

[About the use of rental terminals]
In the shopping system of the present embodiment, the personal terminal 50A and the rental terminal 50B can be used as the customer terminal device 50. By making the rental terminal 50B available to customers, even customers who do not own a mobile terminal such as a smartphone that can be used as a personal terminal can shop using the customer terminal device 50. can. Also, for example, even a customer who owns a mobile terminal such as a smartphone can actually try using the rental terminal 50B when considering installing a shopping application on his / her mobile terminal and using it for shopping. You can try it.

The flow of the procedure when the customer makes a purchase using the rental terminal 50B will be described.
When the customer enters the store, he / she goes to the rental corner of the rental terminal 50B. In the lending corner, the lending terminal 50B in the standby state is placed in a state of being charged by the charging device 90.

FIG. 13 shows an example of the appearance of the charging device 90. The charging device 90 in the figure shows an example in which five terminal holders 92 are provided for the main body 91. As shown in the figure, the rental terminal 50B is loaded so as to lean against the terminal holder 92. With the loaded state in this way, non-contact charging (wireless power supply) is performed from the terminal holder 92 to the rental terminal 50B. The non-contact charging supported by the charging device 90 is not particularly limited, including an electromagnetic induction method, a magnetic resonance method, and the like.

Since the charging device 90 in the figure includes five terminal holders 92, five rental terminals 50B can be charged at the same time. The number of terminal holders 92 included in the charging device 90 is not particularly limited. That is, the number of rental terminals 50B that can be charged by one charging device 90 at the same time is not particularly limited. Further, the number of charging devices 90 installed in one rental corner is related to the number of rental terminals 50B to be prepared in the rental corner and the number of rental terminals 50B that can be charged by one charging device 90. It may be determined accordingly.
In the case of the charging device 90 in which non-contact charging is performed as shown in the figure, the terminal holder 92 and the rental terminal 50B do not need to be associated with each other on a one-to-one basis. For example, when a clerk or a customer wants to charge one rental terminal 50B, the rental terminal 50B may be loaded into any terminal holder 92 from among the vacant terminal holders 92.

The customer picks up any rental terminal 50B from the rental terminals 50B set in the charging device 90. A shopping application startup screen (FIG. 11A) is displayed on the display unit 504 of the rental terminal 50B in the standby state. The customer operates the transaction start instruction button BT10 on the activation screen of the lending terminal 50B that he / she picked up. After that, the customer can use the rental terminal 50B as the customer terminal device 50 to register the product while reading the product code as described above. When the product registration is completed, the customer performs a settlement transition instruction operation to display a code display screen (FIG. 11 (D)) in which the two-dimensional code is arranged on the lending terminal 50B. The customer is displayed on the code display screen. The two-dimensional code is read by the settlement device 40, and the settlement is performed.
When the payment is completed by the payment device 40, the shopping is completed. The customer who has finished shopping returns to the rental corner where the rental terminal 50B that he / she has been using has been prepared, and places the rental terminal 50B in one of the empty terminal holders 92 in the charging device 90. To be done. As a result, the rental terminal 50B has been returned.

[Management of personal terminals and rental terminals in stores]
In the store where the shopping application of the present embodiment is introduced, the personal terminal 50A and the rental terminal 50B are used together as the customer terminal device 50. Therefore, it is preferable that transactions performed using the customer terminal device 50 are managed so that it can be identified whether the personal terminal 50A or the rental terminal 50B is used. As a result, for example, in monitoring the current transaction status in the store by the transaction information management device 80, managing the transaction results by the transaction management device 60, etc., either the personal terminal 50A or the lending terminal 50B is used for each transaction. Can be managed separately.

[Example of processing procedure for identifying the type of customer terminal device]
The flowchart of FIG. 14 shows an example of a processing procedure executed by the transaction management device 60 in connection with the type identification of the customer terminal device 50. The type identification of the customer terminal device 50 here is to identify whether the customer terminal device 50 used for product registration in a store is a personal terminal 50A or a rental terminal 50B.

Step S101: When the customer starts using the customer terminal device 50, the transaction start instruction button BT10 (FIG. 11A) on the activation screen is operated. The customer terminal device 50 transmits a transaction start request to the transaction management device 60 in response to the operation of the transaction start instruction button BT10.
When the customer terminal device 50 is the personal terminal 50A, the transaction start request includes customer identification information or application identification information. In the following description, a case where the transaction start request transmitted by the personal terminal 50A includes customer identification information will be taken as an example.
On the other hand, in the case of the rental terminal 50B, the user who uses the shopping application like the personal terminal 50A is not specified. Therefore, the transaction start request transmitted by the lending terminal 50B includes the application identification information.
In step S101, the transaction management device 60 waits for the transaction start request transmitted from the personal terminal 50A or the lending terminal 50B as the customer terminal device 50 to be received.

Step S102: When the transaction management device 60 receives the transaction start request, the transaction management device 60 determines whether or not the customer terminal device 50 to which the transaction start request is transmitted is the lending terminal 50B.
The transaction management device 60 determines that the lending terminal 50B is the lending terminal 50B when the received transaction start request includes the application identification information. On the other hand, the transaction management device 60 determines that the personal terminal 50A is the personal terminal 50A when the received transaction start request includes the customer identification information.

Step S103: When it is determined that the customer terminal device 50 to which the transaction start request is transmitted is the lending terminal 50B, the transaction management device 60 generates cart information corresponding to the lending terminal 50B. This process corresponds to the process of generating the cart information in step S2 in correspondence with FIG. 10.
The transaction management device 60 stores the application identification information included in the transaction start request in the area of the customer / application identification information in the cart information generated by the step S103, and stores the application identification information included in the transaction start request in the area of the terminal type flag in the lending terminal 50B. Stores "1" indicating that there is.

Step S104: When it is determined that the customer terminal device 50 to which the transaction start request is transmitted is the personal terminal 50A, the transaction management device 60 generates the cart information corresponding to the personal terminal 50A. Similar to step S103, this process also corresponds to the process of step S2 in correspondence with FIG. 10.
The transaction management device 60 stores the customer identification information included in the transaction start request in the area of the customer / application identification information in the cart information generated by the step S104, and stores the customer identification information included in the transaction start request in the area of the terminal type flag in the personal terminal 50A. Stores "0" indicating that there is.

In this way, in the present embodiment, in the cart information, information that can identify whether the customer terminal device 50 used for the corresponding transaction is the personal terminal 50A or the rental terminal 50B is stored. .. That is, in the transaction management device 60, if the customer identification information is stored in the cart information or the terminal type flag is "0", the customer terminal device 50 used for the corresponding transaction is the personal terminal 50A. Identify as being. Further, in the transaction management device 60, if the application identification information is stored in the cart information or the terminal type flag is "1", the customer terminal device 50 used for the corresponding transaction is the lending terminal 50B. Identify as being.

According to the processes of steps S103 and S104 above, the application identification information is stored in the customer / application identification information area in the cart information when the destination of the transaction start request is the lending terminal 50B, and the individual. In the case of the terminal 50A, the customer identification information is stored. In this case, if the formats (formats) such as the number of digits of the application identification information and the customer identification information and the character type used for each digit are different, the format of the identification information stored in the customer / application identification information area is different. It is possible to identify whether the customer terminal device 50 used for the corresponding transaction is the rental terminal 50B or the personal terminal 50A. In this case, the terminal type flag may be omitted.
On the other hand, when the transaction start request transmitted by the personal terminal 50A includes the application identification information instead of the customer identification information, the corresponding customer terminal device 50 is in the customer / application identification information area of the cart information. The application identification information is stored regardless of whether it is the personal terminal 50A or the rental terminal 50B. In this case, the transaction management device 60 may identify whether the customer terminal device 50 is the personal terminal 50A or the lending terminal 50B by referring to the terminal type flag in the cart information.

[About the identification display of personal terminals and rental terminals]
According to the processing procedure of FIG. 14, the identification result of whether the customer terminal device 50 is the personal terminal 50A or the rental terminal 50B is reflected in the cart information stored in the transaction management device 60.
The transaction information management device 80 shows a terminal status screen showing the status of the rental terminal 50B in the store and the transaction status corresponding to each personal terminal 50A used in the store, based on the cart information stored in the transaction management device 60. Can be displayed on the display unit 806.

FIG. 15 shows an example of a terminal status screen displayed on the display unit 806 of the transaction information management device 80. In the terminal status screen of the figure, the rental terminal status area AR10 and the personal terminal status area AR20 are arranged.

The rental terminal status area AR10 is an area in which a list of statuses for each rental terminal 50B deployed in the store is displayed. The list items IM-A arranged in the lending terminal status area AR10 indicate the current status of the corresponding lending terminal 50B, respectively.
In the lending terminal status area AR10, the list items IM-A are arranged in the order of arrangement according to the terminal number assigned to the lending terminal 50B. The figure shows an example in which 14 list items IM-A are arranged in order corresponding to each terminal number of "001" to "014".
If the list item IM-A exceeds the number that can be displayed with respect to the size of the rental terminal status area AR10, the remaining list item IM-A is scrolled or page-changed in the rental terminal status area AR10. A may be displayed.

In the list item IM-A, a display indicating the status of the corresponding lending terminal 50B is performed. The list item IM-A displays, for example, one of the statuses of "renting", "waiting", "spare", "power off", "unusable", and "leaving". Of these statuses, except for the "power off" status, the "rental", "standby", "spare", "unusable", and "leaving" statuses are the rental terminal 50B with the power turned on. Is in the activated state.

When the status of "Lending" is displayed in the list item IM-A, it indicates that the corresponding lending terminal 50B is rented to the customer. For example, depending on the state in which the corresponding rental terminal 50B is removed from the charging device 90, the status becomes "rental".

Further, when the status of "Lending" is displayed, in the list item IM-A, the contents corresponding to any of the sub-status of registration, settlement in progress, and settlement completion are displayed.
In the case of the sub-status being registered, for example, "HH: MM: SS start", "registered points 12 points", "approximate total 2320" shown in the list item IM-A of the terminal number "001". The usage start time, the number of registered points at the present time, and the total amount of registered products at the present time (approximate total) are displayed. The usage start time displayed in the list item IM-A may be the time when the corresponding lending terminal 50B is removed from the charging device 90, or the transaction is started in response to the operation of the transaction start instruction button BT10. It may be the time.
The notation "HH: MM: SS" indicates a number as an actual hour, minute, and second.
Further, in the case of the sub-status of "payment in progress", for example, as in the list item IM-A of the terminal number "005", a display indicating the sub-status of "payment in progress" and a two-dimensional code generation time are shown. "QR creation HH: MM: SS" is displayed. The two-dimensional code generation time is the time when the corresponding lending terminal 50B generates and displays the two-dimensional code of the cart identification information in response to the settlement transition instruction operation.

Further, in the case of the settlement completion sub-status, for example, as in the list item IM-A of the terminal number "007", the display indicating the sub-status of "settlement completed" and the "settlement completion HH" indicating the settlement completion time are shown. : MM: SS ”is displayed and“ Elapsed time HH: MM: SS ”indicating the elapsed time from the settlement completion time is displayed.
For example, after the settlement is completed, the customer may return the rental terminal 50B to a place other than the charging device 90 in the specified rental corner, or may intentionally or negligently keep the rental terminal 50B in possession. In such a case, the elapsed time in the list item IM-A is considerably longer than the time normally required for the customer to return the rental terminal 50B to the charging device 90 after completing the settlement. Become. By observing such an elapsed time, the clerk can determine that the rental terminal 50B has not been returned to the charging device 90 in the specified rental corner.

In addition, when the reserved product is registered under the registered sub-status in "Lending", the reserved product is included in the registered product in the corresponding list item IM-A. A display indicating that is displayed. For example, in the list item IM-A of the terminal number "003", "point 12" and "ho 1" are displayed, so that one of the 12 registered points (points) can be registered as a reserved product. Indicates that it is included.
In the list item IM-A of the terminal number "003", the mode indicating the reserved product is other than the pseudo scan input (classification number 3) and the non-scan input (classification number 4) in the classification of the reserved product shown in FIG. Applies when the product registration result of the classification is included.

Further, in the example of the figure, in the list item IM-1 corresponding to the transaction in which it is detected that a fraudulent act called "basket omission" has been performed under the registered sub-status in "lending". Is displayed to indicate that the "basket omission" has been performed. Specifically, in the list item IM-1 of the terminal number "002", "basket" is displayed, indicating that the transaction is "missing the basket".
"Out of basket" is when the product registration result of one of the pseudo scan input (classification number 3) and the non-scan input (classification number 4) is included in the classification of the reserved products shown in FIG. Applies. That is, in the example of the figure, the customer's actions when the product registration results of the pseudo-scan input (classification number 3) and the non-scan input (classification number 4) are obtained are treated as corresponding to "basket omission". Has been made.

When the status of "waiting" is displayed in the list item IM-A, it indicates that the corresponding lending terminal 50B is in the waiting status. The standby state is a state in which the corresponding lending terminal 50B is being charged because it is loaded in the charging device 90 of the lending corner associated with the lending terminal 50B.

The list item IM-1 of the terminal number "009" indicates the status of "waiting". In the list item IM-1 of the terminal number "009", "Waiting: Station 2-2" is displayed, indicating that the user is in a waiting state at the rental corner of Station 2-2. There is.
Further, in the list item IM-1 of the terminal number "009", the charge amount of the corresponding rental terminal 50B is shown, and the estimated usable time according to the charge amount is displayed.

The list item IM-1 of the terminal number "004" also shows the status of "waiting". However, in the list item IM-1 of the terminal number "004", the spare customer terminal device 50, for example, "Let's replace it with a spare device", depending on the amount of charge of the corresponding rental terminal 50B is small. An example is shown in which a message prompting the exchange with is displayed.

When the status of "spare" is displayed in the list item IM-A, it indicates that the corresponding lending terminal 50B is stored as a spare.
In the figure, the list items IM-1 of the terminal numbers “010”, “011”, and “012” indicate the status of “spare”, respectively. In the list item IM-1 of the status of "spare", the current charging state of the corresponding rental terminal 50B is shown.

When the status of "power off" is displayed in the list item IM-A, the corresponding rental terminal 50B indicates that the power is off.
In the figure, the list items IM-1 of the terminal numbers "013" and "014" are displayed as "power off (no communication)", respectively, so that the corresponding rental terminal 50B is in a power off situation. It shows that there is. Further, in the list item IM-1 of the status of "power off", the reason why the power is turned off is displayed, for example, "reason: preliminary storage", "reason: repairing failure". There is.

Further, if the corresponding list item IM-1 is not arranged on the terminal status screen in the figure, but the status of "unusable" is displayed in the list item IM-A, the corresponding lending terminal 50B is displayed. , Indicates that the device cannot be used for some reason, such as a malfunction.
Further, although the corresponding list item IM-1 is not arranged on the terminal status screen in the figure, when the status of "leave" is displayed in the list item IM-A, the corresponding lending terminal 50B is displayed. Indicates that the vehicle is left unattended in a place other than the corresponding rental corner.

The list item IM-A may have different frame portions, background colors, etc., depending on the status and sub-status, registration of reserved products, occurrence of "basket omission", and the like. As a result, the clerk can intuitively grasp the situation of each rental terminal 50B.

On the terminal status screen, the personal terminal status area AR20 is an area in which a list of statuses for each personal terminal 50A being used by the customer at the store is displayed. The list items IM-B arranged in the personal terminal status area AR20 indicate the current status of the corresponding personal terminal 50A, respectively. The situation regarding the personal terminal 50A shown in the list item IM-B is mainly the situation regarding transactions using the corresponding personal terminal 50A.

The list items IM-B in the personal terminal status area AR20 are arranged, for example, from top to bottom in the order in which the use start time is close to the current time. The usage start time is the time when the transaction is started in response to the operation of the transaction start instruction button BT10 by the customer. As for the list item IM-B in the personal terminal status area AR20, the corresponding list item IM-B is newly added at the top of the personal terminal status area AR20 in response to the start of a new transaction by using the personal terminal 50A. The list item IM-B, which has been displayed so far, is displayed so as to be lowered by one step.
If the list item IM-B exceeds the number that can be displayed with respect to the size of the personal terminal status area AR20, the remaining list item IM- is made so that scrolling or page change is performed in the personal terminal status area AR20. B may be displayed.

In the list item IM-B of the personal terminal status area AR20, for example, the user identification information is indicated by displaying "UID: xxxxxxx ...". Further, in the list item IM-B, when the member information is registered in the shopping application installed on the corresponding personal terminal 50A, the member identification information is displayed by displaying, for example, "member identification: xxxxxxx ...". Is displayed. Further, when the member information registered in the shopping application corresponds to a general member, the display is performed, for example, "member identification: general". Specifically, the user identification information and the member identification information may be, for example, an alphanumerical character string having a predetermined number of digits.

Further, in the list item IM-B, information indicating the progress of the corresponding transaction is displayed. For example, in the list item IM-1 on the first line, the shopping application is started at the time HH: MM: SS by displaying "Entering the store (application start) HH: MM: SS", and the start screen is displayed. It is shown to be in the state of being.
In addition, in the list item IM-B on the second line, the corresponding transaction was started at the transaction start time HH: MM: SS due to the display of "shopping start HH: MM: SS". It is shown that there are no registered products yet.
Further, in the list item IM-B on the third row, the current number of registered points and the approximate total are shown according to the corresponding transaction being registered as a product. When the product is being registered, "HH: MM: SS" may indicate the transaction start time.
In addition, in the list item IM-B on the 4th line, the display of "Ho 1" indicates that the registered product contains one reserved product for the corresponding transaction. There is. In the list item IM-B, the reserved merchandise indicated by the above aspect includes unspecified merchandise and merchandise other than unspecified merchandise. That is, the "NON-FILE", "reading NG", "pseudo-scan input", "non-scan input", "age confirmation product", "pharmaceutical product", and "security tag product" of the classification numbers 1 to 7 in FIG. 8 are used. include.
Further, in the list items IM-B on the 5th and 6th rows, it is shown that the product registration is completed, the settlement is started, and the settlement is in progress for the corresponding transaction. When the settlement is in progress, a two-dimensional code is generated according to the settlement transition instruction operation by displaying "QR generation: HH: MM: SS", and the time displayed on the personal terminal 50A is indicated.

The list item IM (IM-A, IM-B) also functions as a button. When the list item IM corresponding to the status during product registration is operated, the transaction information management device 80 displays a transaction details screen showing the details of the corresponding transaction.

FIG. 16 shows an example of the transaction details screen P1. The transaction details screen P1 in the figure shows an example of a window format displayed superimposed on the terminal status screen. Further, the terminal status screen in the figure shows an example in which one of the list items IM-A corresponding to the rental terminal 50B is operated.

The terminal status area AR2 and the registered product list area AR3 are arranged on the transaction details screen P1 in the figure.

The terminal status area AR2 is an area in which an outline of the transaction content and information on the status of the customer terminal device 50 itself are displayed as the status of the corresponding customer terminal device 50.
In the terminal status area AR2, the lending start time, the number of registered points, the approximate total, the breakdown of the registered reserved products, the remaining charge, the last read product code, the sales floor where the customer terminal device 50 is currently located, and the customer terminal device. The coordinates of the current position of 50 are displayed.

The registered product list area AR3 is an area for presenting a list of products registered by the customer terminal device 50.

When the reserved products include the reserved products, the list items of the reserved products are prioritized and arranged from the upper side of the left column in the registered product list area AR3. That is, in the registered product list area AR3, the list items of the reserved products are arranged in order from the beginning.
In the example of the figure, in the registered product list area AR3, the reserved product list area AR31 including the list items of the five reserved products from the upper left corresponds to the fact that the registered products include five reserved products. An example of the formation of is shown. The list items in the reserved product list area AR31 are set to differ from the list items of other products in terms of, for example, the background color.

Then, in the reserved product list area AR31, first, the list items for which the products are specified among the reserved products are arranged in order, and then the list items corresponding to the unspecified products for which the products are not specified are arranged in order. Has been done. That is, in the reserved product list area AR31, an array divided by a list item corresponding to the product identification in which the product is specified among the reserved products and a list item corresponding to the unspecified product in which the product is not specified. It has become.

In the registered product list area AR3, a list item corresponding to normal registration is arranged following the reserved product list area AR31. In the figure, in the registered product list area AR3, an example is shown in which the list items corresponding to normal registration are arranged in descending order of product price.
Among the list items of the registered product list area AR3, in the list items corresponding to the product identification, the product name, the registered quantity, the price according to the registered quantity, etc. of the specified product are shown.

In the list item for each reserved product in the reserved product list area AR31, the hold release declaration button BT31 is arranged. The hold release declaration button BT31 is a button on which an operation for declaring the hold release of the corresponding product is performed.

The hold release declaration button BT31 also has a function as an icon indicating that the corresponding list item corresponds to the hold item. In the hold release declaration button BT31, the name of the classification of the corresponding product as the corresponding hold product is indicated.
Specifically, for example, age confirmation products (classification number 5), pharmaceutical products (classification number 6), crime prevention tag products (classification number 7), and cancellation products (classification number 8) are supported by the hold release declaration button BT31, respectively. The name indicating the classification is displayed. In addition, for unspecified products (classification numbers 1 to 4), the name "pending product" is collectively displayed.
In the figure, as the display on the hold release declaration button BT31, the list item on the first line is displayed as "age confirmation" corresponding to the age confirmation product (classification number 5), and the list on the second line. The item is displayed as "security tag" corresponding to the security tag product (classification number 7), and the list item on the third line corresponds to the drug (classification number 6). An example labeled "Pharmaceutical" is shown. Further, the list items on the 4th row and the 5th row each show an example of being displayed as "pending product".
Thumbnail image TNs are arranged in the list items on the 4th and 5th lines. The thumbnail image TN is an image taken by the customer terminal device 50 while the product registration operation is being performed for the corresponding unspecified product. The thumbnail image TN may be a still image or a moving image.
The clerk visually distinguishes the list item corresponding to the unspecified product from the list item corresponding to the reserved product for which the product is specified, depending on whether or not the thumbnail image TN is arranged. can. In addition, the clerk can grasp what the product registered as the unspecified product was actually by the content displayed in the thumbnail image TN.
In the hold release declaration button BT31, the display indicating the corresponding classification may be a pattern such as an icon indicating the classification.

Among the list items of reserved products, the list items corresponding to the specified products such as age confirmation products (classification number 5), medicines (classification number 6), security tag products (classification number 7), etc. are specified. The product name, registered quantity, price according to the registered quantity, etc. of the product are shown.
On the other hand, in the list item corresponding to the unspecified product, the content corresponding to the classification of the corresponding pending product is displayed. Specifically, in the case of an unspecified product as NON-FILE (classification number 1), the product is indicated as NON-FILE and read as shown in the list item on the fifth line of the figure. The code may be shown. Further, in the case of unspecified products (classification number 4) of reading NG (classification number 2), pseudo scan input (classification number 3), and non-scan input (classification number 4), the fourth line of the figure is shown. A message indicating that the product code could not be read may be displayed like a list item.

Further, on the transaction details screen P1, an age confirmation button BT21, a terminal call message transmission button BT22, and a list screen transition button BT23 are arranged.
When the list screen transition button BT23 is operated, the transaction details screen P1 is deleted and the display returns to the terminal status screen.

If the registered product includes a reserved product, the clerk needs to cancel the hold of the reserved product (including canceling the registration of the reserved product). Such a hold release of the reserved product can be performed by the clerk by operating the settlement screen displayed on the settlement device 40.

Further, in the present embodiment, the store clerk can operate the transaction information management device 80 to process the reserved product as follows. In this case, the transaction information management device 80 is installed in the service counter. In the present embodiment, when the reserved product is registered during the product registration, the customer can have the clerk release the reserved product at the service counter at the stage before the product registration is completed. .. When the customer wants to release the hold of the reserved product at the service counter, the customer goes to the service counter and asks the clerk in charge to release the hold of the reserved product.

The clerk who receives the request to release the hold of the reserved product identifies which list item IM displayed on the terminal status screen corresponds to the customer terminal device 50 possessed by the customer. At this time, when the customer terminal device 50 possessed by the customer is the rental terminal 50B, the terminal number of the rental terminal 50B may be confirmed and the list item IM-A on which the same terminal number is displayed may be specified. When the customer terminal device 50 possessed by the customer is the personal terminal 50A, the stamp for writing the member identification information of the customer and the list item IM-A on which the same member identification information is displayed may be specified.
Alternatively, the list item IM is specified by causing the transaction information management device 80 to read the code (two-dimensional code or bar code) indicating the terminal number of the lending terminal 50B or the code of the member identification information shown on the membership card. You may try to do so. In this case, the identified list item IM may be highlighted in a predetermined manner.
In this case, the code indicating the terminal number of the rental terminal 50B may be affixed to the rental terminal 50B or may be displayed on the rental terminal 50B. The code of the member identification information may be read from the membership card possessed by the customer. In this case, the membership card may be displayed on the shopping application of the customer terminal device 50.

The clerk performs an operation on the list item IM specified as described above to display the transaction details screen P1 and releases the hold of the reserved product as follows.
When the clerk cancels the hold of the hold product (age confirmation product (classification number 5), drug (classification number 6), security tag product (classification number 7)) of the classification in which the product can be identified among the hold products. Performs a predetermined response work according to each classification, and then performs an operation (for example, a tap operation) on the hold release declaration button BT31 arranged in the corresponding list item in the hold product list area AR31. , The entire list of reserved items may be tap-operable.
When the product to be released from hold is an age confirmation product, the clerk confirms that the customer is an adult as a response work, and operates the hold release declaration button BT31 arranged in the corresponding list item.
In addition, if the product to be released from hold is a drug, the clerk will explain to other clerk who has pharmacist qualification as a response work if he / she has pharmacist qualification. Then, operate the hold release declaration button BT31 placed in the corresponding list item.
If the product to be released from hold is a security tag product, the clerk removes the security tag attached to the target product and presses the hold release declaration button BT31 placed in the corresponding list item as a response work. Manipulate.
When the hold release is performed for the hold item of the category for which the product can be specified as described above, the display on the operated hold release declaration button BT31 is, for example, "confirmed" (confirmed) from the state indicating the corresponding classification. Alternatively, it may change to a state indicating that the hold has been released, such as "can be released from hold").

In addition, the clerk is a pending product classified as an unspecified product (NON-FILE (classification number 1), reading NG (classification number 2), pseudo scan input (classification number 3), non-scan input (classification number 4)). When releasing the hold, first, the hold release declaration button BT31 arranged in the list item corresponding to the hold product to be released is operated in the hold product list area AR31.
In response to the operation of the hold release declaration button BT31 corresponding to the unspecified product in this way, the status confirmation screen is displayed instead of the transaction details screen P1.

FIG. 17 shows an example of the status confirmation screen P10. The status confirmation screen P10 is a screen showing the status when the unspecified product corresponding to the operated hold release declaration button BT31 is registered by the operation of the customer terminal device 50 of the customer.
The status confirmation screen P10 in the figure gives an example of a case where an unspecified product to be processed for release of hold is classified into a pseudo scan input (classification number 3).
Further, in the status confirmation screen P10 in the figure, the customer terminal device 50 is held by the holder portion provided in the cart, and in the state where the customer terminal device 50 is held by the holder portion, the customer terminal device 50 is in the shopping cart. Corresponds to the case where it is possible to take an image. The customer causes the customer terminal device 50 held in the holder to scan the product code.

On the status confirmation screen P10 in the figure, the captured images G11, G12, and G13 are arranged in this order from left to right. The captured images G11, G12, and G13 are captured images obtained when the customer terminal device 50 is trying to scan the product code of the corresponding unspecified product.

The arrangement order of the captured images G11, G12, and G13 from left to right corresponds to the passage of time during which the imaging was performed.
First, the second (center) captured image G12 is an captured image captured when the product to be processed is within the imaging range of the customer terminal device 50 during the product registration operation.
The first captured image G11 is an image captured before the second captured image G12, and is an captured image captured at a timing before the product to be processed falls within the imaging range.
The third captured image G13 is an image captured after the second captured image G12, and is an captured image captured at a timing when the product to be processed is out of the imaging range.

In this case, the clerk can grasp the situation at the time of the product registration operation in which the unspecified result occurs by looking at the captured images G11, G12, and G13.
Specifically, in the example of the figure, the store clerk first puts the product to be processed into the shopping cart at the stage before the product registration operation is performed by the transition from the captured image G11 to the captured image G12. I can understand that it wasn't there.
Further, the store clerk can grasp that the unspecified result as the pseudo scan input (classification number 3) has occurred because the part of the product code in the product is hidden by the hand from the captured image G12.
In addition, the clerk can grasp what the product to be processed is by the captured image G12. Specifically, in the example of the figure, the clerk grasps that the product to be processed is "canned yakitori".
Further, the clerk can grasp that the product to be processed has been put in the shopping cart after the product registration operation is performed by the transition from the captured image G12 to the captured image G13.

When the situation at the time of the product registration operation is grasped as described above, the clerk operates the screen transition button BT35 to display the product information input screen. Depending on the operation of the screen transition button BT35, the product information input screen is displayed instead of the status confirmation screen P10.
Further, after providing the scanner unit in the transaction information management device 80, the clerk can change the product code of the product to be processed, which has been put in the shopping cart, while the status confirmation screen P10 is displayed. You may perform an operation to read by the scanner unit. Depending on whether the transaction information management device 80 succeeds in reading the product code, the product information input screen is displayed.

FIG. 18 shows an example of the product information input screen P40. The product information input screen P40 is a screen on which a clerk inputs the product information of the product to be processed as an unspecified product. The product information input screen P40 may also be displayed so as to be superimposed on the reserved product processing screen, as in the case of the status confirmation screen P10, for example.

On the product information input screen P40, the product information area AR41, the input operation area AR42, the registration button BT41, the cancel button BT42, and the captured image area AR43 (target captured image area AR43-1, next captured image area AR43-2) are arranged. To.

The product information area AR41 is an area in which product information regarding the corresponding unspecified product is shown. In the product information area AR41 in the figure, a product name, a product code, a price, a registered quantity, and the like are shown. The registered quantity can be input (registered) by operating the plus button and the minus button arranged in the product information area AR41.

The input operation area AR 42 is an area in which a software keyboard and buttons for inputting product information in the product information area AR 41 are arranged.
In the input operation area AR42, it is possible to switch between a keyboard with a key layout corresponding to numerical input and a keyboard with a key layout corresponding to character input according to the operation.

A preset call button BT421 is arranged in the input operation area AR42. By operating the preset call button BT421, a preset key screen in which the corresponding preset keys are arranged for each product is displayed.
For example, when the unspecified product to be processed is either read NG (classification number 2), pseudo scan input (classification number 3), or non-scan input (classification number 4), the clerk tells the product to be processed. If you know the product name, you may display the preset key screen. The clerk can input the product information of the product to be processed into the product information area AR41 by operating the preset key of the corresponding product from the preset keys arranged on the displayed preset key screen. ..

Further, a product code input declaration button BT422 is arranged in the input operation area AR42. The product code input declaration button BT422 is a button operated when declaring that the product code input operation is performed.
After operating the product code input declaration button BT422, the clerk inputs the numerical value of the product code indicated by printing or the like in the product to be processed to the keyboard arranged in the input operation area AR42, for example. I do. As a result, the product code is input to the product information area AR41.

When the product information input screen P40 is displayed in response to the clerk having the transaction information management device 80 read the product code, the read product code is in the state of being input in the product information area AR41. In the case of an unspecified product other than NON-FILE (classification number 1), for example, since the product is specified from the product master based on the read product code, the product name, price, etc. are also input. It is in a state.

When the product to be processed is classified into NON-FILE (classification number 1), the product code is input to the product information area AR41 when the product information input screen P40 is displayed. It is in a state. In this case, the clerk is made to input the product name, price, etc. in the product information area AR41 by operating the keyboard arranged in the input operation area AR42.

The registration button BT41 is a button operated to confirm the information input to the product information area AR41 as described above, release the hold of the corresponding unspecified product, and make the product normally registered. ..
The cancellation button BT42 is a button on which an operation for instructing cancellation of registration is performed for the corresponding unspecified product.

The clerk confirms the content entered in the product information area AR41 and then operates the registration button BT41. As a result, 40 releases the pending state of the unspecified product so far and processes it so that it is included in the registered product.
After the registration button BT41 is operated, the product information input screen P40 is erased, and the process returns to the reserved product processing screen (FIG. 14). At the stage of returning to the hold product processing screen, the hold release declaration button BT31 of the list item of the product to be processed in the hold product list area AR31 has been released from the hold state by displaying, for example, "confirmed". Is shown.

Alternatively, when the clerk determines that the product to be processed should not be registered, the clerk operates the cancel button BT42 to cancel the registration and collects the product from the shopping cart.
Even after the cancel button BT42 is operated, the product information input screen P40 is erased and the transaction details screen P1 (FIG. 16) is returned. At the stage of returning to the transaction details screen P1, the list item of the product to be processed in the reserved product list area AR31 has changed to a predetermined mode indicating that the registration has been cancelled.

The status confirmation screen P10 and the product information input screen P40 may indicate the classification number, classification name, or the like of the corresponding unspecified product.

Further, in the captured image area AR43, the target captured image area AR43-1 is an area in which the target captured image is displayed. The target captured image is an captured image obtained by imaging when the unspecified product to be processed this time is a product whose code has not been acquired and is within the imaging range during the product registration operation. The captured image displayed in the target captured image area AR43-1 may be the same as the captured image G12 displayed on the status confirmation screen P10, for example.
In the captured image area AR43, the next captured image area AR43-2 is an area in which the next captured image is displayed. The next captured image is an captured image obtained by imaging at the time of the product registration operation performed after the product registration operation corresponding to the code-unacquired product to be processed this time. That is, the next captured image is captured when the product registration operation corresponding to the code-unacquired product to be processed this time is followed by the product registration operation in which the product code is first successfully read and the product can be identified. It is an image.
As the next captured image, among the captured images obtained in response to the next product registration operation, if there is a captured image in which an article as a product is detected, the captured image including the detected product is selected. To.

As a result of the customer performing a product registration operation for a certain product, if the customer terminal device 50 cannot read the product code normally and is registered as a product for which the code has not been acquired, the customer again for the same product. I often try to register products. In such a case, the customer will perform the product registration operation twice in succession for the same product. In such a case, if the product code is normally read by the second product registration operation, the same product is registered as a reserved product, which is a product for which the code has not been acquired, and based on the read product code. Double registration with the normal registration in which the product is specified will be performed.
When double registration is performed in this way, the procedure for canceling the hold by the clerk is to delete the registration of the hold product as a product for which the code has not been acquired and process it so that the normal registration for the same product remains. You just have to. In order to facilitate such processing, it is required that the store clerk can easily grasp whether or not the product for which the code has not been acquired, which is the target of the hold release, is double-registered.

Therefore, in the present embodiment, the captured image area AR43 (target captured image area AR43-1 and next captured image area AR43-2) is arranged on the product information input screen P40 to display the target captured image and the next captured image. I am doing it.
When the target captured image and the next captured image indicate that the same product has been captured, the clerk can confirm that the double registration has been performed. Therefore, in this case, the clerk operates, for example, the cancel button BT42 arranged on the product information input screen P40. As a result, the products for which the code has not been acquired to be processed are deleted from the list of registered products.

Further, in the next captured image area AR43-2 in the figure, the quantity display unit NM is arranged. The quantity display unit NM is an image unit that shows, for example, the quantity (registered quantity) registered by the customer's operation for the product normally registered by the product registration operation when the next captured image is captured.
By arranging the quantity display unit NM, the clerk grasps the registered quantity of the product that is normally registered in duplicate with the unspecified product that is the target of the hold release at the stage of performing the hold release operation. It is possible to accurately perform work and operations related to releasing the hold.

When the product to be processed is an unspecified product as NON-FILE (classification number 1), the customer terminal device 50 has successfully read the product code but has not specified the product. Is notified. In this case, since it is possible to know that the customer has succeeded in reading the product code, it is unlikely that double registration will occur by performing the product registration operation for the same product again. Therefore, when the registration result of the product to be processed corresponds to NON-FILE, the captured image area AR43 (processed image, next captured image) may not be displayed.
However, depending on the customer, for example, even if the notification is performed according to the unregistered result as NON-FILE, there is a possibility that the product code reading has failed and the product registration operation is performed again. .. Therefore, even when the registration result of the product to be processed corresponds to NON-FILE, the captured image area AR43 (processed image, next captured image) may be displayed. If the captured image area AR43 is displayed, the clerk can easily grasp that the unregistered result of NON-FILE for the same product is double-registered.

The next captured image may be displayed together with the captured images G11, G12, and G13 on the status confirmation screen P10, for example. In this case, the clerk can determine whether or not double registration has occurred at the stage when the status confirmation screen P10 is displayed before the product information input screen P40 is displayed.

When the transaction management device 60 is capable of acquiring the position information transmitted from each of the customer terminal devices 50 (which may be at least the rental terminal 50B), the transaction information management device 80 is the acquired position. Based on the information, the display indicating the position of the lending terminal 50B may be displayed corresponding to each transaction.

[About the function to prevent rental terminals from being taken out of the store]
The rental terminal 50B should be returned to the rental corner in the store when the use by the customer is completed. However, there is a possibility that a customer who has finished shopping using the rental terminal 50B may inadvertently move out of the store while carrying the rental terminal 50B. Alternatively, it may be taken out of the store by a malicious customer.
Therefore, in the present embodiment, when the rental terminal 50B is taken out of the store, the transaction information management device 80 notifies to that effect. The clerk who is monitoring by the transaction information management device 80 can grasp that the rental terminal 50B has been taken out of the store by the notification by the transaction information management device 80, and can take immediate action. ..
The device for notifying that the rental terminal 50B has been taken out of the store is other than the transaction information management device 80, such as the management device 10, the settlement device 40, and the business terminal owned by the clerk. There may be. In the following description, a case where the notification is performed by the transaction information management device 80 will be given as an example.

[Example of processing procedure for notification of taking out of store]
With reference to the flowchart of FIG. 19, an example of a processing procedure executed by the transaction management device 60 and the transaction information management device 80 in relation to the notification corresponding to the lending terminal 50B being taken out of the store will be described. The process shown in the figure is a process executed by the transaction management device 60 corresponding to the lending terminal 50B of 1.

First, an example of the processing procedure of the transaction management device 60 will be described.
Step S201: In the rental terminal 50B in the present embodiment, when the power is turned on and the rental terminal 50B is operating, the positioning unit 508 periodically positions the self-position, and transaction management manages the position information indicating the positioned self-position. It is transmitting to the device 60.
The transaction management device 60 is waiting for the position information transmitted from the lending terminal 50B to be received.

Step S202: Upon receiving the location information, the transaction management device 60 determines whether or not the position of the rental terminal 50B indicated by the received location information is outside the position range corresponding to the store. If it is determined that the position of the rental terminal 50B is within the position range corresponding to the store, the process of the figure is terminated and the process is started from step S201.

Step S203: When it is determined in step S202 that the position of the rental terminal 50B is outside the position range corresponding to the store, the rental terminal 50B is taken out of the store. Therefore, the transaction management device 60 in this case transmits the out-of-store movement notification to the transaction information management device 80.
The out-of-store movement notification is information for notifying that the rental terminal 50B has moved out of the store. The out-of-store movement notification includes the terminal identification information of the rental terminal 50B that has moved out of the store. Further, the transaction management device 60 manages the received location information every time the location information transmitted from the lending terminal 50B is received after moving outside the store after the transmission of the out-of-store movement notification. It may be transmitted to the device 80.

Next, an example of the processing procedure of the transaction information management device 80 will be described.
Step S301: The transaction information management device 80 is waiting for the out-of-store movement notification transmitted by step S203 to be received.

Step S302: The transaction information management device 80 executes the out-of-store movement notification in response to the receipt of the out-of-store movement notification. The out-of-store movement notification is a notification to the store clerk that the rental terminal 50B has moved out of the store.
The out-of-store movement notification may be performed, for example, by displaying on the display unit 806 of the transaction information management device 80. Further, the out-of-store movement notification may be accompanied by, for example, an electronic sound or voice output by the transaction information management device 80.
Further, when the lending terminal 50B is configured to transmit the location information, the transaction information management device 80 is the position transmitted from the lending terminal 50B moved out of the store from the transaction management device 60 in the out-of-store movement notification. Based on the information, the current position of the rental terminal 50B moved out of the store, the movement locus, and the like may be displayed on the display unit 806.
Further, after assigning a number to each of the rental terminals 50B, the number of the rental terminal 50B moved out of the store may be displayed in the out-of-store movement notification.
Further, the transaction information management device 80 acquires and acquires an image of a surveillance camera that images a customer who has a rental terminal 50B that has moved out of the store, for example, in response to receiving a notification of movement outside the store. The image may be displayed.

It should be noted that the out-of-store movement notification of the rental terminal 50B by the process shown in the figure requires that the rental terminal 50B periodically transmits the position information. That is, it is necessary that the rental terminal 50B is turned on and then the position information transmission function is turned on. Therefore, for example, when a malicious customer turns off the position information transmission function of the rental terminal 50B or turns off the power supply, the out-of-store movement notification cannot be performed.
Therefore, the lending terminal 50B may not be operated with respect to the general lending terminal 50B, and may not be able to perform operations such as turning off the power supply and turning off the position information transmission function unless the operation is performed by a special procedure, for example. Alternatively, the rental terminal 50B may be locked so that operations such as turning off the power and turning off the location information transmission function cannot be performed. Alternatively, for example, by controlling the transaction management device 60, the transaction information management device 80, or the like, the power is returned to the on state even if the power is turned off, or the position information transmission function is switched to the on state even if the power is turned off. You may be made to do so.

[About return management of rental terminals]
The rental terminal 50B is operated so as to be placed in a state of being charged by the charging device 90 installed in the rental corner in the standby state not being used by the customer. Further, here, an example is taken in which a plurality of lending corners are provided in a store, and a lending terminal 50B to be placed corresponding to each lending corner is predetermined. In response to this, when the customer makes a purchase using the lending terminal 50B installed in a certain lending corner, the store uses the lending terminal 50B in the original lending corner according to the end of the shopping. We have established a return rule that the product should be loaded into the terminal holder 92 of the charging device 90 and returned so that it can be charged.
However, not all customers who use the rental terminal 50B will return the rental terminal 50B according to the above return rule. That is, in the store, there is a possibility that the rental terminal 50B may fail to be returned due to the following cases.
One is a case (case 1) in which, for example, a customer places a lending terminal 50B in a lending corner different from the original lending corner where the lending terminal 50B should originally be placed. In addition, there is a possibility that the customer leaves the original rental corner without setting it so that it can be charged by the charging device 90 (case 2).
As a case where the rental terminal 50B is not returned according to the return rule, there is a case where the customer takes the rental terminal 50B out of the store, and such a case can be dealt with by the above-mentioned out-of-store notification.

Therefore, in the present embodiment, as described below, the store clerk is mainly notified that the return failure has occurred according to Cases 1 and 2 (return failure notification). As a result, the clerk can put the rental terminal 50B in the state of incomplete return into a state of being charged at the original rental corner.

[Example of processing procedure for notifying the return failure of the rental terminal]
The flowchart of FIG. 20 shows an example of a processing procedure executed by the lending terminal 50B and the transaction information management device 80 in connection with the return failure notification.
First, an example of a processing procedure executed by the lending terminal 50B will be described. In the explanation of the figure, it is premised that the lending terminal 50B periodically positions its own position by the positioning unit 508 and transmits the position information indicating the measured self-position to the transaction management device 60. Further, the rental terminal 50B is in a state where the shopping application is operating.

Step S401: The rental terminal 50B on which the shopping application is operating determines whether or not it has been removed from the charging device 90 in the charging state. When the rental terminal 50B detects that, for example, the state in which the power for charging has been supplied has changed to the state in which the power supply has been stopped, it is determined that the rental terminal 50B has been removed from the charging device 90. ..

Step S402: When it is determined in step S401 that the charging device 90 has been removed, the lending terminal 50B transmits a terminal take-out notification to the transaction information management device 80.
The terminal take-out notification is information for notifying that the rental terminal 50B, which was being charged, has been removed from the charging device 90, and the customer has taken out the rental terminal 50B from the rental corner for use in shopping.
The terminal take-out notification includes the terminal identification information of the lending terminal 50B of the transmission source. As the terminal identification information of the rental terminal 50B, the application identification information of the shopping application installed on the rental terminal 50B may be used. In the following description, the case where the terminal identification information is the application identification information will be taken as an example.

Step S403: When it is determined in step S401 that the charging device 90 has not been removed, or after the processing of step S402, the rental terminal 50B determines whether or not charging by the charging device 90 has started. If it is determined that charging is not started, the process is returned to step S401.

Step S404: When it is determined in step S403 that charging has started, the lending terminal 50B transmits a terminal return notification to the transaction information management device 80.
The terminal return notification is information for notifying that the rental terminal 50B has been returned to the rental corner in response to the start of charging by the charging device 90. The terminal return notification includes the terminal identification information of the lending terminal 50B of the sender.

Next, an example of the processing procedure executed by the transaction information management device 80 will be described.
Step S5011: The transaction information management device 80 is waiting for receiving the terminal take-out notification transmitted from the lending terminal 50B in step S402.

Step S502: When the terminal take-out notification is received, the transaction information management device 80 acquires the take-out position. The take-out position is a position corresponding to the lending corner brought out by the customer by the lending terminal 50B, which is the transmission source of the terminal take-out notification.
The transaction information management device 80 stores information on the position range of each lending corner. In acquiring the take-out position, the transaction information management device 80 determines which lending corner position range includes the position indicated by the position information transmitted from the same lending terminal 50B as the sender of the terminal take-out notification. May acquire the take-out position. The transaction information management device 80 stores the acquired take-out position in association with the terminal identification information of the lending terminal 50B that is the transmission source of the terminal take-out notification.
In the following description, the rental terminal 50B that is the transmission source of the terminal take-out notification may be described as the rental terminal 50B to be monitored.

Step S503: The transaction information management device 80 determines whether or not the customer has started product registration within a certain period of time after the customer possesses the rental terminal 50B to be monitored. The fixed time here may be set based on, for example, a general time required from the customer taking out the lending terminal 50B to operating the transaction start instruction button BT10 in order to start the product registration.
In the present embodiment, the transaction management device 60 generates cart information in response to a transaction start request from the customer terminal device 50 (personal terminal 50A, lending terminal 50B). Product registration using the customer terminal device 50 can be treated as being started in response to the generation of cart information. The transaction management device 60 of the present embodiment transmits a product registration start notification to the transaction information management device 80 in response to the generation of cart information. The product registration start notification includes the terminal identification information of the corresponding customer terminal device 50.
It can be considered that the timing at which the take-out position is acquired by step S502 corresponds to the timing at which the rental terminal 50B to be monitored is removed from the charging device 90 by the customer.
Therefore, as the process of step S503, the transaction information management device 80 receives the product registration start notification including the terminal identification information of the rental terminal 50B to be monitored within a certain time from the time when the take-out position is acquired by step S502. Determine if it is. As a result, the transaction information management device 80 can determine whether or not the product registration has been started within a certain time from the time when the take-out position is acquired in step S502.

Step S504: When it is determined in step S503 that the product registration is started within a certain time, the transaction information management device 80 further determines whether or not the settlement is started within a certain time after the product registration is started. judge. The fixed time here is, for example, required from the customer starting the product registration using the rental terminal 50B to ending the product registration and having the settlement device 40 read the code displayed on the rental terminal 50B. It may be set based on a general time.
The settlement device 40 transmits a subtotal amount request to the transaction management device 60 in response to reading the code displayed by the customer terminal device 50, and the settlement screen is based on the subtotal information transmitted from the transaction management device 60. Is displayed and the settlement process is executed. In the present embodiment, when the transaction management device 60 transmits the subtotal information in response to the reception of the subtotal amount request, the application identification information stored in the customer / application identification information area of the cart information used for generating the subtotal information. Is transmitted to the transaction information management device 80 as a settlement start notification including the terminal identification information.
As the process of step S504, the transaction information management device 80 receives the settlement start notification including the terminal identification information of the loan terminal 50B to be monitored within a certain time from the time when it is determined that the product registration is started by step S503. Determine if it is. Thereby, the transaction information management device 80 can determine whether or not the settlement is started within a certain time from the start of the product registration.

Step S505: When it is determined in step S504 that the settlement is started within a certain time, the transaction information management device 80 further sets the lending terminal by step S404 within a certain time from the time when it is determined that the settlement is started. It is determined whether or not the terminal return notification transmitted from 50B has been received. The fixed time here is a general time required for a customer who has registered a product using the rental terminal 50B to return the rental terminal 50B to the rental corner after starting payment with the payment device 40. It may be set based on.

Step S506: When it is determined that the terminal return notification has been received within a certain time from the time when it is determined in step S505 that the settlement has started, the transaction information management device 80 returns the lending terminal 50B to be monitored. Get the position.
In acquiring the return position, the transaction information management device 80 determines the return position by determining which lending corner position range the position indicated by the position information transmitted from the monitored lending terminal 50B is included in. You may get it.

Step S507: The transaction information management device 80 determines whether or not the take-out position acquired in step S502 and the return position acquired in step S506 correspond to the same lending corner.
When it is determined that the rental terminal 50B to be monitored corresponds to the same rental corner, the rental terminal 50B to be monitored has been properly returned so as to be charged by the charging device 90 in the original rental corner after the customer finishes using the terminal. become. Therefore, in this case, step S508 may be skipped and the process of the figure may be terminated.

Step S508: When it is determined in step S507 that the take-out position acquired in step S502 and the return position acquired in step S506 correspond to different lending corners, the following states are applicable. .. That is, in this case, the monitored lending terminal 50B is returned to a certain lending corner, but is returned to a lending corner different from the correct lending corner to which the monitored lending terminal 50B is assigned. Charging is performed by the charging device 90.
Therefore, the transaction information management device 80 in this case outputs a terminal movement request. The terminal movement request is a request to the clerk to move the monitored rental terminal 50B from the current rental corner to the correct rental corner.
Specifically, the transaction information management device 80 displays on the display unit 806 the position (lending corner) where the monitored lending terminal 50B is currently located and the correct lending corner as a terminal movement request. Then, the transaction information management device 80 displays the content instructing the clerk to move the monitored lending terminal 50B to the correct lending corner as a terminal movement request. Further, in this case as well, the number assigned to the rental terminal 50B to be monitored may be displayed.
The clerk who sees such a terminal movement request display goes to the rental corner where the monitored rental terminal 50B is placed, has the monitored rental terminal 50B, moves to the correct rental corner, and charges the charging device 90. It can be charged at. That is, the clerk can return the lending terminal 50B placed in the wrong lending corner to the correctly returned state.

Step S509: When it is determined in step S503 that a certain time has passed without starting product registration, or when it is determined in step S504 that a certain time has passed without starting settlement, or When it is determined in step S505 that a certain period of time has passed without receiving the terminal return notification, the rental terminal 50B to be monitored is in the following situation. That is, the monitored lending terminal 50B is in a situation where the customer has not completed the shopping process that would normally have already been completed since the customer took it out of the lending corner, and the customer has it in the store. ..
Therefore, the transaction information management device 80 in this case outputs a terminal status confirmation request. The terminal status confirmation request is a request for confirmation of the current status of the rental terminal 50B to be monitored.
As a terminal status confirmation request, for example, while indicating the position of the rental terminal 50B to be monitored in the store, the store clerk is instructed to confirm the status of the rental terminal 50B to be monitored. The content may be displayed. Also in this case, the number assigned to the rental terminal 50B to be monitored may be displayed.
The clerk who sees such a display of the terminal status confirmation request goes to the position of the rental terminal 50B to be monitored indicated in the display of the terminal status confirmation request, and what kind of situation is the rental terminal 50B to be monitored? It is possible to confirm whether or not, and take appropriate measures according to the confirmed situation.

<Modification example>
Hereinafter, a modified example of the present embodiment will be described. The following modifications may be combined as appropriate.

[First modification]
The transaction management device 60 may send a transaction completion notification to the lending terminal 50B in response to the completion of the corresponding settlement by the settlement device 40. Upon receiving the transaction completion notification, the lending terminal 50B can recognize that the corresponding transaction has been completed. Depending on the receipt of the transaction completion notification, the lending terminal 50B may, for example, return the display to the startup screen or display a message inviting the customer to return the lending terminal 50B to the correct lending corner. good.

[Second modification]
It should be noted that, for example, at the same timing as the out-of-store movement notification in step S302 of FIG. 19 is performed by the transaction information management device 80, for example, by remote control of the transaction information management device 80 or the transaction management device 60, the rental terminal to be monitored is monitored. The warning notification for the customer may be performed at 50B. The warning notification may be performed by display, sound (electronic sound, voice), vibration, or the like. In this case, for example, the volume of the warning sound, the type of the warning sound, and the like may be changed so that the degree of the warning increases according to the passage of time from the start of the warning notification.

[Third modification example]
The lending terminal 50B may be configured to notify the transaction information management device 80 of the remaining battery level at a predetermined timing or periodically.
The transaction information management device 80 relates to the remaining battery level, for example, according to the fact that the remaining battery level notified when the rental terminal 50B to be monitored is not charged by the charging device 90 becomes a certain level or less. Information may be output by display or the like. Further, at the same timing, the rental terminal 50B may also be notified of information regarding, for example, the remaining battery level.
Further, the transaction information management device 80 may be configured to output information regarding the remaining battery level of each standby lending terminal 50B charged by the charging device 90. As a result, the store clerk who monitors using the transaction information management device 80 can grasp the remaining battery level for each of the standby lending terminals 50B. For example, among the rental terminals 50B charged by the charging device 90, the clerk accurately replaces the fully charged spare rental terminal 50B with the one whose battery level is less than a certain level. You can. At this time, for example, the transaction information management device 80 obtains the usage frequency (turnover rate) of the current rental terminal 50B, and the remaining battery level needs to be replaced with a spare rental terminal 50B according to the obtained usage frequency. The threshold may be calculated.

Further, among the standby rental terminals 50B charged by the charging device 90, the rental terminal 50B whose remaining battery level may become zero before the use corresponding to one transaction is completed is , The transaction information management device 80 or the transaction management device 60 may be controlled so as not to be usable for product registration.

[Fourth variant]

In the above embodiment, the rental terminal 50B has a corresponding rental corner, and the rental terminal 50B taken out from the rental corner by the customer for use is returned to the same rental corner.
On the other hand, in this modification, after the customer takes out the rental terminal 50B from the specified rental corner and uses it, the rental terminal 50B is stored in a collection box installed at a predetermined place in the store. Will be done. In this case, as the rental terminal 50B is used, the number of rental terminals 50B that have been used increases in the collection box. Therefore, the clerk collects the rental terminal 50B from the collection box at a certain timing, and installs the collected rental terminal 50B in the charging device of the specified rental corner. As a result, the rental terminal 50B is in a state of waiting while being charged at the rental corner.
Hereinafter, the work in which the clerk collects the rental terminal 50B from the collection box and installs the collected rental terminal 50B in the charging device of the specified rental corner is also referred to as "terminal collection work".

Also in this modification, the process shown in FIG. 10 is executed by the customer terminal device 50 (including the lending terminal 50B), the settlement device, and the transaction management device 60. Further, the lending terminal 50B may execute the process shown in FIG. Further, the transaction information management device 80 may execute the process shown in FIG. Further, the lending terminal 50B transmits, for example, a notification that the two-dimensional code is generated (two-dimensional code generation notification) to the transaction information management device 80 when the two-dimensional code is generated in response to the settlement transition instruction operation. good.
As a result, the transaction information management device 80 determines whether the status of the lending terminal 50B is "waiting", "product registration", "two-dimensional code generation", "payment", or "payment completed". Can be managed. That is, the transaction information management device 80 acquires the status information indicating the status of the lending terminal 50B.

"Standby" is a state in which the rental terminal 50B is loaded so that it can be charged by the charging device at the specified rental corner. In "standby", the rental terminal 50B may be in a charging state, or may be in a state in which charging is stopped in response to a fully charged state.

"Product registration in progress" is a state in which the lending terminal 50B is taken out by the customer and the process corresponding to the product registration is being executed in response to the operation of the transaction start instruction button BT10.

The "two-dimensional code generation" is a state in which the lending terminal 50B displays the two-dimensional code in response to the settlement transition instruction operation.

"During settlement" means that the settlement device 40 is executing the settlement process in response to the customer reading the two-dimensional code, so that the rental terminal 50B has already completed the product registration process. , It is still treated as being owned by the customer.

"Settlement completed" means that the settlement process has been completed by the settlement device 40, but the rental terminal 50B has not yet been loaded into the charging device at the specified rental corner.
In these statuses, the statuses such as "Product registration in progress", "Settlement in progress", and "Settlement completed" may be used as information indicating the status of the corresponding transaction (transaction status).

Further, also in this modification, the transaction information management device 80 may display the terminal status screen (FIG. 15) based on information such as cart information transmitted from the transaction management device 60. At this time, the transaction information management device 80 may display the above-mentioned status in the list item IM-A for the transaction corresponding to the above-mentioned lending terminal 50B. That is, the transaction information management device 80 of this modification acquires the status information indicating the status of the lending terminal 50B from the transaction management device 60.

Then, in the present modification, as illustrated below, a predetermined notification may be performed according to the number of lending terminals 50B in a predetermined status becoming a predetermined number or more. In the following description, the case where the transaction information management device 80 is configured to execute the determination that the number of lending terminals 50B in the predetermined status has exceeded the predetermined number and the notification according to the determination result will be given as an example. ..

[Notification example 1]
The transaction information management device 80 monitors (counts) the number of lending terminals 50B in the "product registration" state, and then determines whether or not the number of lending terminals 50B in the "product registering" state exceeds a certain level. Is determined, and when the value exceeds a certain level, notification may be performed.

The fact that the number of rental terminals 50B in the "product registration" state exceeds a certain level means that the rental terminals 50B in the "standby" state are in short supply. If the situation where the lending terminal 50B in the "waiting" state continues to be insufficient, all the lending terminals 50B in the "waiting" state will be used soon. This leads to a customer who wants to use the rental terminal 50B gives up using the rental terminal 50B. Further, in the situation where the number of rental terminals 50B in the "product registration in progress" state is a certain amount or more, the number of rental terminals 50B housed in the collection box is also small.
Therefore, when the number of the rental terminals 50B in the “registering product” state being monitored exceeds a certain level, it is preferable to replenish the spare rental terminals 50B by deploying them in the rental corner.

Therefore, in response to the fact that the number of lending terminals 50B in the "product registration" state of the transaction information management device 80 exceeds a certain level, the transaction information management device 80 has, for example, many terminals being rented. , The clerk may be instructed to add the spare rental terminal 50B to the rental corner and deploy it.

Such notification may be displayed, for example, in a predetermined area on the terminal status screen, or may be performed by a pop-up screen displayed so as to be superimposed on the terminal status screen. This point may be the same in the case of the following notification.

[Notification example 2]
Further, the transaction information management device 80 monitors the number of lending terminals 50B in the "product registration completed" state, and then determines whether or not the number of lending terminals 50B in the "product registration completed" state exceeds a certain level. It may be determined and notified when the value exceeds a certain level.
The state of "commodity registration completed" corresponds to any of the states of "two-dimensional code generation", "payment in progress", and "payment completed". That is, the state of the rental terminal 50B as "finished product registration" is a state in which the product registration process is completed but the product is not charged at the specified rental corner.

Even when the number of rental terminals 50B in the "product registration completed" state exceeds a certain number, the rental terminals 50B in the "standby" state are insufficient as in the case of the "product registration in progress" state. It can be said that we are in a situation where we are doing. Further, when the number of rental terminals 50B in the "commodity registration completed" state exceeds a certain number, there is a possibility that a large number of rental terminals 50B are accommodated in the collection box.
Therefore, the transaction information management device 80 instructs, for example, the terminal collection work and waits even if the terminal collection work is performed, in response to the fact that the number of lending terminals 50B in the "product registration completed" state becomes a certain number or more. If the number of rental terminals 50B in the state is small, a notification may be given to instruct the spare rental terminal 50B to be deployed in the standby state.

[Notification example 3]
Further, the transaction information management device 80 monitors the number of lending terminals 50B in the "standby" state, and then determines whether or not the number of lending terminals 50B in the "waiting" state has exceeded a certain level. , It may be set to notify when it exceeds a certain level. The "standby" state corresponds to the state of being "charging" because the rental terminal 50B is loaded in the charging device at the rental corner. The "charging" state here may be a state in which the rental terminal 50B is loaded in the charging device, and includes a state in which charging is stopped according to the fully charged state. It's okay.

When the number of rental terminals 50B in the "standby" state is a certain number or more, it means that the use of the rental terminals 50B by customers is small at present.
The rental terminal 50B provides the customer terminal device 50 to customers who have not yet used the personal terminal 50A, for example, with the goal of increasing the number of customers who shop using the personal terminal 50A. It may be rented out for the purpose of having you try the shopping you used. With such a background, when the use of the rental terminal 50B is low, for example, it is advisable for the clerk to call on the customers who are visiting the store to use the rental terminal 50B.
Therefore, the transaction information management device 80 causes the clerk to, for example, call on the customer to use the lending terminal 50B in response to the fact that the number of lending terminals 50B in the "standby" state reaches a certain number or more. You may give an instruction to notify.

Regarding the number of lending terminals 50B to be monitored in each of the above examples, the number of lending terminals 50B in the corresponding state may be directly recognized, or the number of lending terminals 50B in two or more specific states may be recognized. It may be obtained by performing an operation using a number.
As an example, the number of lending terminals 50B in the "waiting" state is the number of lending terminals 50B in each state of "product registration", "two-dimensional code generation", "payment in progress", and "payment completed". It can be obtained by subtracting from the total number of rental terminals 50B currently operating in the store.

The transaction information management device 80 may be configured to perform a predetermined notification according to the number of lending terminals 50B in a predetermined state being a certain number or less. For example, when the number of rental terminals 50B in the "standby" state exceeds a certain level, the store clerk is notified to instruct the terminal collection work and the deployment of the spare rental terminal 50B to the rental corner. good.

The transaction information management device 80 also acquires states such as "product registration", "two-dimensional code generation", "payment in progress", and "payment completed" for the personal terminal 50A, and corresponds to each state. Predetermined notification may be performed according to the number of personal terminals 50A.

In addition to the transaction information management device 80, the notification of this modification may be performed by a POS register in which the clerk is operating the product registration, a clerk terminal owned by the clerk, or the like.

[12th variant]
In addition, in the above-described embodiment and modification, a part of the processing executed by the customer terminal device 50, the transaction information management device 80, etc. is connected to the customer terminal device 50 via communication, which is a higher-level device such as the transaction management device 60. May be made to run. Further, in the above-described embodiment and modification, a part of the processing executed by the settlement device 40 may be executed by a higher-level device such as the transaction management device 60 connected to the settlement device 40 via communication.
As one of the above-described aspects, the shopping system of the present embodiment may be provided with a configuration of a thin client system.
As an example, the transaction management device 60 may be configured as a server for thin clients (for example, a cloud server), and the customer terminal device 50, the transaction information management device 80, and the like may function as thin clients. In this case, the thin client terminal such as the customer terminal device 50 or the transaction information management device 80 transmits the captured image and information such as a command corresponding to the operation performed to the self to the transaction information management device 80.
