The customer information in the figure includes customer identification information, customer name, customer registration date, product cancellation information, customer rank, number of points, and the like.
Customer identification information is identification information that uniquely identifies a customer.
As the customer identification information (or instead of the customer identification information), for example, application identification information that is uniquely attached (eg, sequentially) to each installed shopping application may be used. Terminal identification information unique to the mobile terminal 60 in which the shopping application is installed may be used as the customer identification information (or instead of the customer identification information). The terminal identification information is, for example, a telephone number assigned to a customer who is the user of the mobile terminal 60, a MAC (Media Access Control) address, or the like, which is unique to the hardware of the mobile terminal 60. It may be identification information.
The customer name is the customer's name, nickname, or the like. The customer registration date is the date and time when the customer was registered. The product cancellation information is information related to cancellation after product registration. The customer rank is a rank according to the customer's purchase record. When generating customer information for a new customer, customer identification information, customer name, and customer registration date are generated, but since the actual transaction (product registration) has not yet started, other information (product cancellation information, etc.) ) is not generated.

The transaction management device 20 is used, for example, at the time of customer registration (for example, when the mobile terminal 60 uses the shopping service provided by the transaction management device 20 from the outside (for example, a predetermined server that provides general applications, the transaction management device 20). Generate and store customer identification information when downloading or installing the shopping application). Further, the transaction management device 20 acquires the information entered in the name column of the registration form (input form) using the mobile terminal 60 at the time of customer registration, for example, and stores the information as the customer name. Further, the transaction management device 20 acquires, for example, the current date and time at the time of customer registration, and stores it as the customer registration date.

Transaction management device 20 stores part or all of the customer information in another device (such as a file server that transaction management device 20 can access) in place of or in addition to storing the customer information in its own storage unit. You can memorize all of them.

FIG. 7B shows an example of shop information stored in the storage unit 202 of the transaction management device 20. As shown in FIG. The store information in the figure includes store identification information, store name (branch name), store identification information 1, and store identification information 2. FIG.
The store identification information is identification information that uniquely identifies the store. The store identification information shown in FIG. 7B is composed of a store (store name) or company code and a branch code.
The store name is the name of the store. The store name shown in FIG. 7B is composed of a store (store name) or company and a branch name.
The shop identification information 1 is information of a two-dimensional code (QR code (registered trademark), etc.) for identifying a shop to trade (a shop where merchandise is bought and sold).
The store identification information 2 is store location information (GPS information) for specifying the store to trade with.
In the example shown in FIG. 7B, the store identification information and the store identification information 1 are different, but the store identification information and the store identification information 1 may be the same.

The transaction management device 20 may acquire and store store information and the like from an external source (such as a server (not shown) at the headquarters that controls each store). In addition, transaction management device 20 stores a portion of the store information or stores it in another device (such as a file server accessible by transaction management device 20) in place of or in addition to storing the store information in its own storage unit. You can memorize all of them.

Cart information is information for managing individual transactions. Transaction management device 20 generates cart information at the start of a transaction. In addition, the transaction management device 20 updates the cart information (when the product is stored in the cart information, it means that the product has been registered) as the transaction progresses (each time the product is registered). may be resolved).

FIG. 7C is an example of cart information stored in the storage unit 202 of the transaction management device 20. As shown in FIG.
The cart information in the figure includes cart identification information, transaction start date and time, transaction end date and time, customer identification information, registered product information, pending product information, and the like.

The cart identification information is identification information that uniquely identifies the cart information. For example, cart identification information includes store identification information, dates, and serial numbers (eg, serial numbers by store and date).
The transaction start date and time is the date and time when the transaction started. The transaction start date and time may be, for example, the date and time when the cart information is generated. The transaction start date and time may be the registration date and time of one product (the date and time when the registered product information (registered product 1) in FIG. 7C is stored). Both the date and time of cart information generation and the date and time of registration of one product item may be stored separately.

The transaction end date and time is the end date and time of the transaction. For example, the transaction start date and time may be the settlement date and time. The customer identification information is customer identification information that identifies the customer of the transaction. When cart information is generated, cart identification information, transaction start date and time, and customer identification information are generated, but since the actual transaction (product registration) has not yet started, other information (transaction end date and time, etc.) is generated. not. The settlement date and time may be the settlement start date and time, or may be the settlement end date and time. Both the settlement start date and settlement end date and time may be separately stored as the transaction end date and time.

The registered product information (total) is information updated each time a product is registered. The registered product information (total) includes the number of products (number of products), approximate subtotal amount (for example, subtotal amount before discounts are reflected), subtotal amount, and the like. The registered product information (registered product 1) is registered information of one item of product. The registered product information (registered product 2) is registered information of two items of products. In the example shown in FIG. 7C, illustration of registered product information (registered product 3) to registered product information (registered product 5) is omitted. The registered product information (registered product N; N is an integer) includes product code, product name (product name), price, and the like.

The registered product information (N) may include the registration date and time of the N item product. In other words, the transaction management device 20 may store the registration date and time of the registered product as the registered product information. The registration date and time of each product may be used as a criterion for judging the necessity of application of services such as time service and the effect after application.

The pending product information (total) is information updated each time a pending product is registered. The reserved product information (total) includes the number of reserved products of all types (number of products) and the number of reserved products for each type (number of products). In this embodiment, reserved products are classified into a plurality of types, and each classification is managed by a classification number (reserved major classification number, reserved minor classification number) (details will be explained with reference to FIG. 8). In the example of FIG. 7(C), "Total number of items: 3" in the pending product information (total) indicates that the number of all types (total of pending products with large classification numbers "1" to "4") is 3. , and "NON-FILE: 2" indicates that the number of pending products classified as NON-FILE (the total of pending products with the major classification number "1") is 2, and "Reading NG: 1 ” indicates that the number of pending products classified as reading NG (total of pending products with large pending classification number “2”) is one.

NON-FILE means that the bar code or product code was successfully scanned at the store (although the product code could be read), but the product code was not stored (registered) in the product file. In other words, pending products classified as NON-FILE are pending products whose product code has been successfully scanned but whose product code is not stored in the product file.

Reading NG means that the product code was not successfully read (scanned) at the store. In other words, a pending product classified as reading NG is a pending product whose product code has not been successfully read.

Reserved product information (reserved product 1) is information on one item of reserved product. Reserved product information (reserved product 2) is information on two items of reserved products. The reserved product information (reserved product 3) is information of three reserved products.

Reservation product information (reservation product N; N is an integer) includes a reservation major classification number (described later). For example, if the product of item N is a pending product classified as NON-FILE with the pending major classification number "1", the pending product information (reserved product N) is the pending major classification number "1 (NON-FILE )”, including the product code. In addition, if the product of the N item is a reserved product classified as reading NG with the reserved major classification number "2", the reserved product information (reserved product N) is the reserved major classification number "2 (reading NG)". , and image data (captured image captured by the mobile terminal 60). The reserved product information of the reserved product classified as NON-FILE may include image data in addition to the reserved major classification number "1 (NON-FILE)" and the product code.

The information shown in FIG. 7 is an example of information stored by the transaction management device 20, and the transaction management device 20 may store other information (for example, a product file). Information on one product in the product file may include, for example, information such as a product code (product identifier), product name, and price.

FIG. 8 is an explanatory diagram illustrating classification of reserved products according to the present embodiment. As shown in FIG. 8, in the present embodiment, pending products are classified into major categories (categorized by pending major category numbers) and minor categories (categorized by pending minor category numbers). It should be noted that the devices in the merchandise sales data processing system 1 may be able to refer to information such as that shown in FIG.

As shown in FIG. 8, in this embodiment, the pending products are classified into four large categories of pending large category numbers "1" to "4".

A pending product classified into the pending major classification number "1" is a NON-FILE pending product. A NON-FILE pending product is, as described above, a pending product whose product code has been successfully scanned but whose product code is not stored in the product file. In other words, if the product code is successfully scanned, but the product code is not stored in the product file and the product becomes a pending product, the pending product is classified as the pending major classification number "1". As for reserved products classified into the reserved major classification number "1", the item of the product is not specified and the price etc. are unknown.

In FIG. 8, "NON-FILE" of "1 (NON-FILE)" is the classification name (reservation major classification name) of the reserved goods. The same applies to "reading NG" of "2 (reading NG)", "specific product" of "3 (specific product)", and "cancelled product" of "4 (cancelled product)", which will be described later.

In the present embodiment, there is a reserved small classification number "11" as a minor classification under (subordinate to) the large classification of the reserved large classification number "1". Since there is only one pending minor category under the major category of pending major category number "1", the pending product classified into the major pending category number "1" is on hold It is classified under the small classification number "11".

In FIG. 8, "NON-FILE" of "11 (NON-FILE)" is the classification name (reservation minor classification name) of the reserved product. The same applies to “pseudo scan (covering, etc.)” of “21 (pseudo scan (covering, etc.))” and “pseudo scan (short time)” of “22 (pseudo scan (short time))”, etc., which will be described later. .

In FIG. 8, the read operation "yes" indicates that the read operation was performed, the read operation "no" indicates that the read operation was not performed, and the read success or failure "success" indicates that the read operation was not performed. The read success/failure "failure" indicates that the reading by the reading operation failed, and the read success/failure "-" indicates that the read operation was not performed, so the problem is before the success or failure of the reading.

A pending product classified into the pending major classification number “2” is a pending product with reading NG. A read NG pending product is, as described above, a pending product whose product code has not been successfully read. In other words, if the product code becomes unsuccessful in reading the product code and becomes a reserved product, the reserved product is categorized as the reserved major classification number "2". Since the price of the pending product classified into the large pending classification number "2" is unknown and there is a risk of fraudulent operation, it is necessary to confirm the payment by a store clerk at the time of payment.

In the present embodiment, pending minor classification numbers "21", "22", "23", and "24" exist as minor categories under the major category of pending major category number "2". Reservation minor classification number "21" is a reservation product of "pseudo scan (coating, etc.)". The reserved small classification number "22" is the reserved product of "pseudo scan (short time)". Reservation minor classification number "23" is a reservation product of "defective bar code". The pending subcategory number "24" is a "non-scan input" pending product.

The pending product (pseudo scan (covering, etc.)) with the pending small classification number “21” is, for example, the product that has been read (the product is held over), that is, the imaging range of the imaging unit 606 (more than In detail, the product is placed in the readable range of the barcode), but the barcode of the product is not imaged (imaged in the above readable range) A held product that cannot be read because only a part of it is imaged) or a product that has an imaged bar code, but a part of the bar code is covered with, for example, a finger, so that it cannot be read. This is a product or a pending product for which the image of the barcode of the product has been imaged but has been read NG because the imaging angle of the barcode is inappropriate.

A pending product (pseudo scan (short time)) with the pending small classification number “22” is, for example, because the barcode of the product was imaged, but the barcode moved (including passing) at a speed that could not be read. This is a pending product that was read NG at the time.

A pending product (defective barcode) with the pending small classification number “23” is, for example, an image of the barcode of the product, but it cannot be read due to wrinkles, blurring, dirt, reflection, etc. on the printed part of the barcode. It is a pending product.

The pending product (non-scanned input) with the pending minor classification number “24” is, for example, a product that has been placed in the shopping cart 80 without being read (without being held over), and thus read NG. It is a product.

Reserved products with reserved small classification numbers "21" to "24" (that is, reserved products with reserved large classification number "2") may be referred to as reading failure products. In addition, a situation in which an item becomes a pending commodity with pending minor classification numbers "21" to "24" may be referred to as a reading failure state (or simply "reading failure").

In addition, pending products with pending small classification number "21" (pseudo scan (covering, etc.)), pending products with pending small classification number "22" (pseudo scanning (short time)), and pending small classification number "23" (Bad bar code) is common in that it is a pending product for which a reading operation was performed and the reading was not successful. However, the pending product with the pending small classification number “21” (pseudo scan (covering, etc.)) and the pending product with the pending small category number “22” (pseudo scan (short time)) It is thought that there are fewer than the pending product (defective bar code) of classification number “23”. In other words, the pending product (pseudo scan (covering, etc.)) with the pending minor classification number “21” and the pending product (pseudo scanning (short time)) with the pending minor classification number “22” are pseudo-reading operations (reading operation It can also be said that it is a fake scan), so it is called a pending product of pseudo scan (disguised scan).

A reserved product classified into the reserved major classification number "3" is a reserved product of a specific product (described later). A reserved product of a specific product is a reserved product that has been successfully registered, but is a specific product and therefore requires a clerk's response at checkout. In other words, if the product is a reserved product because it is a specific product, the reserved product is classified as the reserved major classification number "3". Reservation products classified under the reservation major classification number "3" are specific products, and thus require confirmation by a store clerk at the time of payment.

In the present embodiment, reserved small classification numbers "31", "32", and "33" exist as minor classifications under the large classification of reserved large classification number "3". Reservation minor classification number "31" is a reservation product of "age confirmation product". The pending subclass number "32" is a pending product of "pharmaceuticals". Reservation minor classification number "33" is a reservation product of "crime prevention tag".

The reserved product (age-confirmed product) of the reserved minor classification number "31" is a reserved product that requires the salesclerk to confirm the customer's age, such as alcoholic beverages and cigarettes.

The pending product (pharmaceutical) with the pending minor classification number “32” is, for example, a pending product that requires a qualified pharmacist or the like to explain to the customer.

The pending item (item with a security tag) of the pending minor classification number "33" is, for example, a pending item that has a security tag attached to it and therefore requires the salesclerk to remove the security tag from the item.

A pending product classified into the pending major classification number "4" is a canceled product pending product. A suspended product of a canceled product is a suspended product that has been successfully registered, but whose registration has been canceled after registration. In other words, if the product becomes a reserved product because the registration is canceled after the product is registered, the reserved product is classified into the reserved major classification number "4". Reservation products classified into reservation major classification number "4" are canceled products (that is, products that are not purchased) and are products that are not taken out of the store.

In this embodiment, there is a reserved small classification number "41" as a minor classification under the large classification of the reserved large classification number "4". Since there is only one pending small category under the large category of pending large category number "4", the reserved small category number "41" is the only one. It is classified under the small classification number "41".

In the above explanation, it is assumed that the reading operation has been performed for the pending product (age confirmation product) with the pending minor classification number “31”. It is classified as a pending product (non-scanned input) of classification number “24”. The same applies to pending products (medicine products) with pending minor classification number "32", pending products (security tag products) with pending minor classification number "33", and pending products (cancelled products) with pending minor classification number "41". be.

In addition, in the above explanation, it is assumed that the reading operation is performed and the reading is successful for the pending product (age confirmation product) with the pending minor classification number "31", but the reading operation is performed and the reading is unsuccessful. In this case, the pending product with the pending minor classification number "21" (pseudo scan (covering, etc.)), the pending product with the pending minor classification number "22" (pseudo scanning (short time)), the pending minor classification number "23" is classified as one of the pending products (defective bar code). The same applies to pending products (medicine products) with pending minor classification number "32", pending products (security tag products) with pending minor classification number "33", and pending products (cancelled products) with pending minor classification number "41". be.

As shown in FIG. 8, the pending large classification number and the pending small classification number are in a higher-order and lower-order relationship, but one or both of them are used depending on the situation. For example, in the cart information shown in FIG. 7(C), an example of storing the pending large category number in the pending product information has been described, but the pending small category number may be stored instead of or in addition to the pending large category number. good too.

Transaction management device 20 stores part of the cart information or stores it in another device (such as a file server that transaction management device 20 can access) instead of or in addition to storing the cart information in its own storage unit. You can memorize all of them.

[Example of basic processing procedure for self-operation]
The sequence diagram of FIG. 9 shows an example of a processing procedure executed by the mobile terminal 60, the settlement device 40, and the transaction management device 20 in response to accounting for one transaction in self-operation. Specifically, the process shown in FIG. 40 and an example of the processing of the transaction management device 20. FIG.

Step S1: The mobile terminal 60 acquires information specifying a store (store specifying information). For example, a two-dimensional code for specifying 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.) so that customers who visit the store can By scanning (reading) the two-dimensional code with the terminal 60, the mobile terminal 60 may acquire the store identification information. When a customer visiting the store activates the shopping application, a screen for instructing the customer to scan the two-dimensional code may be displayed as an activation screen. Upon scanning, the shopping application may be activated, and a screen for informing the customer that the transaction management apparatus 20 is being connected may be displayed as the activation screen.

Further, for example, since a store is specified by its location, a customer who visits the store may acquire location information (GPS information) using the mobile terminal 60 at the store (i.e., acquire the location information of the store as the store-specific information). may be used). When a customer visiting the store activates the shopping application, the location information may be acquired and a screen notifying the customer that the transaction management apparatus 20 is being connected may be displayed as the activation screen. If a plurality of stores are detected from the position information and one cannot be identified, a selection screen may be displayed for the customer to select. Alternatively, the mode may be switched to forcibly acquire the two-dimensional code.

FIG. 10A shows an example of a shopping application startup screen displayed on the display unit 504 of the mobile terminal 60. FIG. The store name is displayed on the startup screen in FIG. This store name is displayed based on the store identification information acquired in step S1.
When the customer starts product registration for shopping, the customer operates a transaction start instruction button BT10 arranged on the startup screen.
In response to the operation of the transaction start instruction button BT10, the mobile terminal 60 transmits to the transaction management device 20 a transaction start request including the acquired shop identification information and customer identification information. The transaction start request may be transmitted in response to the customer's operation on the mobile terminal 60 as described above, or may be transmitted in response to the acquisition of the store identification information without receiving any particular operation. can be
As for the customer identification information, the information entered in the name column of the registration form using the mobile terminal 60 at the time of customer registration (when downloading or installing a shopping application on the mobile terminal 60) is used as the customer information in the transaction management device 20. However, in addition to the transaction management device 20, it may be stored in the storage unit of the mobile terminal 60 as well. In addition, when the store is specified (when the product registration initial screen described later) is acquired, the store name of the store, the service in progress (flyer information distributed on that day), and available coupon information It may be displayed on a screen (a product registration initial screen or a screen different from the product registration initial screen). Information on services and coupons may be acquired from the transaction management device 20 as screen information, for example.

Also, destination information (the address of the transaction management device 20) is acquired at the time of customer registration (when the shopping application is downloaded or installed on the mobile terminal 60) and stored in the storage unit of the mobile terminal 60. You can In the case of scanning a two-dimensional code, in addition to the shop identification information, the destination information is also converted into a two-dimensional code, and by scanning the two-dimensional code with the mobile terminal 60, may also acquire destination information together with the shop identification information.

Step S2: The transaction management device 20, which receives the customer identification information and the store identification information as the transaction start request from the portable terminal 60, generates cart information for the transaction. In the initial state of cart information, cart identification information, transaction start date and time, and customer identification information are stored. Date and time, product information (registered product information, reserved product information, etc.) are not stored.

As described above, the transaction management device 20 stores store information as shown in FIG. ), if the received store identification information is a two-dimensional code, the store identification information is obtained by referring to the store identification information 1, and if the received store identification information is location information (GPS information). If so, the store identification information 2 is referred to and the store identification information is acquired. If the store identification information received from the mobile terminal 60 is the store identification information converted into a two-dimensional code, the transaction management device 20 may acquire the store identification information as it is.

In other words, the transaction management device 20 that has received the customer identification information and the store identification information as the transaction start request from the mobile terminal 60 acquires the store identification information from the store identification information received from the mobile terminal 60, and further acquires the current date. , a serial number is issued (numbered), and the store identification information, the current date, and the serial number are combined and stored as cart identification information in the cart information. In addition, the transaction management device 20 that receives the store identification information and the customer identification information from the portable terminal 60 as a transaction start request acquires the current date and time and stores it as the transaction start date and time (creation date and time) in the cart information. Further, the transaction management device 20 that receives the shop identification information and the customer identification information as the transaction start request from the mobile terminal 60 stores the customer identification information received from the mobile terminal 60 as the customer identification information in the cart information.

Step S<b>3 : The transaction management device 20 that has generated the cart information of the transaction generates product registration initial screen information (screen information of the product registration screen which is the initial screen) and transmits it to the portable terminal 60 . Specifically, the transaction management device 20 generates product registration initial screen information, for example, and transmits the generated product registration initial screen information to the mobile terminal 60 together with the cart identification information.

Step S4: The portable terminal 60 that has received the cart identification information and product registration initial screen information from the transaction management device 20 stores the cart identification information and displays the registration screen on the display unit. Specifically, the portable terminal 60 displays a product registration initial screen as shown in FIG. 10B, for example.

The product registration initial screen is a product registration screen that is displayed first when product registration is started.
On the product registration screen, a captured image area AR1 and a product registration result area AR2 are arranged. The captured image area AR1 is an area in which a captured image obtained by the imaging unit 506 is displayed. A product code (for example, a bar code) imaged within a predetermined range in the imaged image displayed in the imaged image area AR1 is to be read.
The product registration result area AR2 shows the number of registered products (registered points) and the total amount of money according to the products registered so far, and is an area in which list items corresponding to each registered product are arranged. is. In the case of the product registration initial screen shown in the figure, since there is no product registered yet, the product registration result area AR2 is in a blank state with no list items arranged.

Step S5: By the customer's operation, the portable terminal 60 scans the bar code attached to the product to read the product code. In the figure, it is assumed that the bar code has been successfully scanned. Steps S5 to S9 are repeatedly executed each time the bar code attached to the product is scanned.

The portable terminal 60 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 20 .

Step S6: The transaction management device 20 that has received the product registration information (cart identification information and product code) from the mobile terminal 60 identifies the cart information of the transaction from the cart identification information included in the received product registration information. .

Step S7: The transaction management device 20 updates product data in the specified cart information. Specifically, when the received product registration information includes a product code for the N item, the transaction management device 20 adds the product code to the registered product information (registered product N) in the specified cart information. ), 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). The transaction management device 20 also updates the registered product information (total) in the specified cart information.

Step S8: After updating the product data in the cart information, the transaction management device 20 generates product registration update screen information (screen information of the product registration screen, which is an update screen to which the registered product is added), and sends it to the mobile terminal 60. Send. Specifically, the transaction management device 20 displays, for example, a product registration update screen to which the list item Itm of the product registered this time is added in the product registration result area AR2 as shown in FIG. 10(C) on the mobile terminal 60. is displayed, and the generated product registration update screen information is transmitted to the mobile terminal 60 together with the cart identification information.

Note that the product registration screen (product registration update screen) shown in FIG. 10C is displayed on the portable terminal 60 after "○○ bread" is registered as the third product. In other words, transaction management device 20 generates product registration update screen information such that "○○ yogurt" is displayed as list item Itm on portable terminal 60 when "○○ yogurt" is stored in the cart information as one item. Then, when the generated product registration update screen information is transmitted to the portable terminal 60 together with the cart identification information, and "○○ chocolate" is stored in the cart as the second item, "○○ yogurt" is displayed as the list item Itm on the portable terminal 60. and "○○ chocolate" are displayed, the generated product registration update screen information is transmitted to the mobile terminal 60 together with the cart identification information, and "○○ bread" is displayed as the third item. When stored in the cart information, as shown in FIG. 10C, items such as "○○ yogurt", "○○ chocolate", and "○○ bread" are displayed as list items Itm on the portable terminal 60. The registration update screen information is generated, and the generated product registration update screen information is transmitted to the portable terminal 60 together with the cart identification information.

Step S9: The portable terminal 60 that has received the cart identification information and the product registration update screen information from the transaction management device 20 adds the product to the registration screen. Specifically, the portable terminal 60 displays, for example, a product registration update screen as shown in FIG. 10(C). Incidentally, as described above, the product registration screen (product registration update screen) shown in FIG. be.

Step S10: The mobile terminal 60 accepts an instruction operation to shift to settlement as a customer's operation. For example, it accepts a touch of the checkout transfer instruction button BT15 displaying "proceed to checkout" shown in FIG. 10(C).

Step S11: The mobile terminal 60 that has received the payment transfer instruction operation generates a two-dimensional code. In other words, the mobile terminal 60 two-dimensionally encodes information (for example, cart identification information) that is necessary for executing the checkout process for the products purchased by the mobile terminal 60 . The mobile terminal 60 that has generated the two-dimensional code displays the generated two-dimensional code on the display. For example, a code screen in which two-dimensional codes are arranged as shown in FIG. 10(D) is displayed on the display unit.
A message area AR3 is arranged on the code screen. In this case, in the message area AR3, there is a message such as "Please read the following code at the payment machine" to guide the customer to have the scanner unit 406 of the payment device 40 read the code on the code screen. is displayed.

Step S<b>12 : The settlement device 40 scans (reads) the two-dimensional code displayed on the display of the mobile terminal 60 . For example, the settlement device 40 scans a two-dimensional code displayed on the display unit of the mobile terminal 60 that is directed within the recognition range of the scanner unit 406 by the customer.

Step S13: After reading the two-dimensional code displayed on the display of the mobile terminal 60, the settlement device 40 requests the transaction management device 20 to calculate the subtotal amount. For example, the settlement device 40 transmits to the transaction management device 20 a calculation request requesting calculation of the subtotal amount (subcalculation request information) together with the cart identification information obtained from the two-dimensional code.

Step S14: The transaction management device 20, which has received the cart identification information and the small calculation request information from the mobile terminal 60, identifies the cart information of the transaction from the cart identification information.

Step S15: The transaction management device 20 that has specified the cart calculates the subtotal amount 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 20 that has calculated the subtotal amount updates the cart information (stores the subtotal amount (calculated subtotal amount)) and sends the subtotal information indicating the calculated subtotal amount to the settlement device 40 together with the cart identification information. Send.

Step S17: After receiving the cart identification information and the subtotal information from the transaction management device 20, the settlement device 40 displays the subtotal amount on the display section 405. FIG.

Step S18: The settlement device 40 that displays the subtotal amount on the display unit 405 executes payment (settlement). Specifically, the settlement device 40 accepts selection of a settlement 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 settlement completion information together with the cart information to the transaction management device 20, and the transaction management device 20 stores the transaction end date and time (settlement date and time) of the cart.

After scanning the product, the mobile terminal 60 transmits the product code to the transaction management device 20 (S5). (for example, products scanned by moving to another store), the product code may not be transmitted. For example, the mobile terminal 60 acquires and stores location information (GPS information) when visiting the store (or when displaying the product registration initial screen). In addition, the mobile terminal 60 acquires position information when scanning each product, and compares the position information acquired when scanning the product with the position information acquired when visiting the store (or when displaying the initial screen for product registration). do. Then, the mobile terminal 60 permits the transmission of the product code of the product to the transaction management device 20 if the two match (or approximately match), and if they do not match (or approximately match), the mobile terminal 60 permits the transmission of the product code of the product. to the transaction management device 20 may be prohibited.
This makes it possible to prevent inappropriate product registration (for example, product registration for a cart generated at another store or the like).

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

After reading the two-dimensional code displayed on the display unit of the mobile terminal 60, the settlement device 40 requests the transaction management device 20 to calculate the subtotal amount (S13). (for example, products scanned at other stores) may not be requested to calculate the subtotal amount. For example, the settlement device 40 refers to the store identification information of the store (the store identification information of the store may be stored and referred to in the settlement device 40 itself, or may be stored in another accessible device). may refer to the store identification information of the store), and when the two-dimensional code displayed on the display unit of the mobile terminal 60 is read, the cart identification information obtained from the two-dimensional code and the store identification information of the store. Compare with Then, if 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 not, the request to calculate the subtotal amount may be prohibited.
In this way, it is possible to prevent inappropriate settlements (for example, settlements of products registered as products at other stores, etc.).

If the request for the subtotal amount is prohibited as described above, the settlement device 40 displays an error message (for example, "The settlement cannot be made because the product is not from the XX store.") after reading the two-dimensional code. 405 may be displayed. Further, the settlement device 40 may display the message on the clerk side display section 410 instead of or in addition to the display section 405 .

In addition, in the example of the processing procedure of FIG. 9, the transaction management device 20 calculates the subtotal amount. However, for example, the settlement device 40 may acquire the cart information from the transaction management device 20 and calculate the subtotal amount based on the acquired cart information.
Alternatively, the transaction management device 20 transmits cart information to the store controller 10 to request calculation of the subtotal amount, the store controller 10 uses the received cart information to calculate the subtotal amount, and the calculated subtotal amount is , to the settlement device 40 via the transaction management device 20 .

In the settlement process, the transaction management device 20 confirms the customer's cancellation status of the products so far based on the customer information and cart information about the customer, and determines whether or not to issue a warning against fraud. you can When determining that a warning should be given, the transaction management device 20 may cause the settlement device 40 to issue a warning, for example.

In the settlement process, the transaction management device 20 determines whether or not the product information contained in the cart information includes a pending product. You may request product correction instructions. The settlement device 40 that has received the request for the correction instruction of the reserved product may display a notice that there is the reserved product. After confirming the notification, the clerk performs operations such as inputting the price corresponding to the reserved product and canceling the reserved product as cancellation (correction) of the reserved product.

[Change of display mode according to holding status: Overview]
Under self-operation, the customer can use the portable terminal 60 in a state of being held by the holder 71 of the shopping cart 70 (cart holding state) when performing product registration, or can use the portable terminal 60 in the holder 71 of the shopping cart 70. It can also be used in a state in which it is removed from 71 and held in the hand (hand held state).
In this case, the customer can adjust the distance between himself/herself and the portable terminal 60 so as to make it easier to see the contents of the screen and to make it easier to operate. On the other hand, in the cart holding state, the position of the mobile terminal 60 is fixed while the distance from the customer to the mobile terminal 60 is to some extent. It may become difficult to see the contents of the screen, or it may become difficult to operate the screen.

Therefore, the portable terminal 60 of the present embodiment determines whether the mobile terminal 60 is in a handheld holding state or a cart holding state. Screen change control is performed so as to change to a mode different from that in the handheld holding state. As a result, the visibility and operability of the screen in the cart holding state are improved, and the mobile terminal 60 becomes easier to use.
This point will be described below.

[Determination of holding status]
When the mobile terminal 60 performs the above-described screen change control, it determines whether the current self holding state is the cart holding state or the handheld holding state. The portable terminal 60 may be configured to determine whether it is in the cart holding state or the handheld holding state based on the detection information of the motion sensor in the sensor unit 608 . The portable terminal 60 determines whether it is in the cart holding state or the handheld holding state based on a predetermined change pattern or the like in detection signals input from an acceleration sensor or a gyro sensor as a motion sensor.
It should be noted that, without using the motion sensor, for example, it may be possible to determine whether the state is the cart holding state or the handheld holding state as follows.
For example, the mobile terminal 60 may be provided with a sensor that is in a state where pressure is applied or light reception is blocked while the mobile terminal 60 is being held by the holder 71 . The mobile terminal 60 may determine whether it is in the cart holding state or the handheld holding state according to the state detected by the sensor.
Further, for example, a sensor may be provided to the holder 71 to apply pressure or not to receive light when the portable terminal 60 is being held. The holder 71 is communicably connected to the mobile terminal 60 by short-range wireless communication such as Bluetooth. The holder 71 transmits information indicating whether or not the mobile terminal 60 is being held to the mobile terminal 60 according to the detection output of the sensor. Based on the received information, the mobile terminal 60 may determine whether it is in the cart holding state or the handheld holding state.
Also, the mobile terminal 60 may be provided with a sensor for detecting the external temperature. In this case, the temperature of the portable terminal 60 is detected according to the body temperature of the hand applied to the portable terminal 60 when the portable terminal 60 is in the hand-held state, and the temperature is detected by the sensor in the state where the body temperature is not applied when the portable terminal 60 is not in the hand-held state (cart holding state). It may be determined whether it is in a cart-holding state or a handheld-holding state based on the temperature.
Further, for example, the customer performs an operation of designating the cart holding state when setting the cart holding state, and performs an operation of designating the hand holding state when setting the handheld holding state to the mobile terminal 60 . may be made In this case, the mobile terminal 60 determines whether the mobile terminal 60 is currently in the cart holding state or the handheld holding state based on which of the cart holding state and the handheld holding state is specified. you can
In the following description, an example will be described in which the mobile terminal 60 uses the detection signal of the motion sensor to perform determination.

[Example of change in display mode according to holding state]
During product registration, the portable terminal 60 displays a product registration screen. When the mobile terminal 60 determines that the current holding state of itself is the handheld holding state, the mobile terminal 60 displays the product registration screen in the mode illustrated in FIG. 10(C). Here, the product registration screen in the form illustrated in FIG. 10C is treated as being in a standard state.

FIG. 11(A) extracts and shows the product registration result area AR2 on the product registration screen in the same standard state as shown in FIG. 10(C). The product registration result area AR2 on the product registration screen in the standard state shown in the figure is treated as a standard size.
As shown in FIG. 11A, the standard size product registration result area AR2 includes an approximate calculation area AR21 and a registration list area AR22. In the approximate calculation area AR21, the number of items registered (registered points) and the total amount corresponding to the items registered so far are displayed, and a settlement transfer instruction button BT15 is arranged. The registration list area AR22 is an area in which list items Itm corresponding to each registered product are arranged. In each of the list items Itm a quantity area 221 is arranged. The quantity area AR221 is an area indicating the registered quantity (registered quantity) of the corresponding product. The quantity area AR221 also functions as a button for instructing display of a product registration change screen, which will be described below.

In the product registration result area AR2 in the standard state shown in FIG. 11A, when the quantity area AR221 in one list item Itm is operated, a product registration change screen is displayed. The merchandise registration change screen is a screen on which an operation is performed to change the registered content of the merchandise corresponding to the list item Itm including the operated quantity area AR221, such as changing the registered quantity or canceling the registration.

FIG. 12 shows an example of the product registration change screen P30 displayed in response to the operation of the quantity area AR221 in the standard product registration result area AR2 as described above. The product registration change screen P30 in the figure shows an example in which a pop-up screen is superimposed and displayed on the product registration screen. In addition, the product registration change screen P30 in the figure has a small size that occupies a part of the product registration result area AR2.

The product registration change screen P30 in the same figure is displayed in response to the selection of the list item Itm of the product "○○ chocolate" among the three list items Itm in the product registration result area AR2 in the same figure. Become. In this case, in the product registration result area AR2, the two list items Itm for products other than "○○ chocolate" are grayed out to indicate that they are not selectable, and the list item Itm for "○○ chocolate" is grayed out. It indicates that it is a selection target by not being in .

The product registration change screen P30 has a cancel button BT31, a quantity price area AR30, a plus button BT32-1, and a minus button BT32-2.
The cancel button BT31 is a button operated to cancel the registration of the target product. When the cancel button BT31 is operated and the registered quantity of the target product is 2 or more, the cancellation is performed for all the registered quantity.
The quantity/price area AR30 indicates the registered quantity of the target product corresponding to the current time and the price according to the registered quantity.
The plus button BT32-1 is a button operated when making changes to increase the registered quantity of the target product. Each time the plus button BT32-1 is operated, the registered quantity is changed to increase by one.
The minus button BT32-2 is a button operated when making a change to decrease the registered quantity of the target product. Each time the minus button BT32-2 is operated, the registered quantity is changed to decrease by one.
When the plus button BT32-1 or the minus button BT32-2 is operated to change the registered quantity, the registered quantity and price in the quantity price area AR30 are changed.

It should be noted that decreasing the registered quantity in accordance with the operation of the minus button BT32-2 may also be treated as canceling the product. That is, when the registered quantity of the registered product is reduced, the product corresponding to the reduced quantity may be treated as canceled.

For example, when the list item Itm corresponding to the target product is operated while the product registration change screen P30 is displayed, the product registration change screen P30 is erased and the product registration screen is returned to the displayed state. .

When canceling the total quantity of the target product (cancelling the registration), the customer operates the cancel button BT31. When the cancel button BT31 is operated, for example, after the product registration change screen P30 is erased, a confirmation screen is displayed. The customer performs a cancellation instructing operation (for example, an operation on the execution button) on the confirmation screen if the cancellation can be performed as it is. In response to the cancellation instruction operation being performed, the confirmation screen is erased and the product registration screen is displayed again. In this case, on the product registration screen displayed after the confirmation screen is cleared, the list item Itm of the product "○○ chocolate", which is the object of cancellation this time, is deleted.

On the other hand, when the mobile terminal 60 determines that the current self holding state is the cart holding state, the product registration result area AR2 on the product registration screen changes from the standard state to the standard state as shown in FIG. Change to an enlarged form.
In the product registration result area AR2 of FIG. 11B, the area sizes of the approximate area AR21 and the list items Itm in the registration list area AR22 are displayed enlarged from the standard state. In the approximate calculation area AR21, the displayed characters and the adjustment shift instruction button BT15 are enlarged from the standard state in accordance with the expansion of the area size. Also, in the list item Itm, the characters indicating the product name, price, etc. and the quantity area AR221 are enlarged and displayed as the area size is enlarged.
In addition, in the product registration result area AR2 of FIG. 11B, the number of list items Itm that can be displayed in the registration list area AR22 is increased by expanding the approximate area AR21 and the list items Itm as described above. is less than the standard state. Specifically, in the product registration result area AR2 of FIG. 10C, three list items Itm are displayed so as to fit therein, but in FIG. List area AR22 is in an occupied state.

Here, in the registration list area AR22 of FIG. 11(B), among the three products registered, "○○ chocolate", which is second in registration order, and "○○ bread", which is third in registration order. Two corresponding list items Itm are displayed. That is, in the registration list area AR22 in the same figure, the list item Itm of the last product in the order of registration is arranged at the bottom, and the list items Itm are arranged above it so as to trace back the order of registration. By arranging the list items Itm in this way, the customer can immediately grasp what the most recently registered product is.
In the state shown in FIG. 11B, the first list item Itm of "○○ yogurt" that is not displayed in the registration list area AR22 is displayed by, for example, a scrolling operation or a page turning operation on the registration list area AR22. can be made
Note that the list items Itm may be arranged in the registration order from the first in the product registration result area AR2.

Even under the mode in which the enlarged display is performed as shown in FIG. 11B, it is possible to operate the quantity area AR221 in the list item Itm. When the quantity area AR221 in one list item Itm is operated under the state shown in FIG.

The product registration change screen P40 in FIG. 13 is displayed in a size larger than the product registration change screen P30 in FIG. 12 so as to be superimposed on the product registration screen.
In addition, the product registration change screen P40 of FIG. 13 is displayed in response to the selection of the list item Itm of the product "○○ chocolate" among the three list items Itm in the product registration result area AR2 of FIG. 11(B). Here is an example of what is displayed. A target product name area AR41 is arranged on the product registration change screen P40. In the target product name area AR41, the product name of the product whose registered content is to be changed is displayed. Specifically, the target product name area AR41 in FIG. 10 displays “XX chocolate”, indicating that the product whose registered content is to be changed is “XX chocolate”.

In the product registration change screen P40 in the figure, in addition to the target product name area AR41, the unit price area AR42, the quantity area AR43, the plus button BT41-1, the minus button BT41-2, the price area AR44, the cancel button BT42, and the confirmation button BT42. A button BT43 is arranged.
The unit price area AR42 indicates the unit price of the target product.
The quantity area AR43 indicates the quantity specified for the target product.
The plus button BT41-1 is a button that is operated when making changes to increase the registered quantity of the target product. The minus button BT41-2 is a button operated when making a change to decrease the registered quantity of the target product.
The price area AR44 indicates the price of the target product according to the quantity indicated in the quantity area AR43.
The cancel button BT42 is a button operated to cancel the registration of the target product.
The decision button BT43 is a button for performing an operation to confirm the quantity shown in the quantity area AR43 as the registered quantity.

When changing the registered quantity, the customer operates the plus button BT41-1 and the minus button BT41-2 to specify the quantity, and then operates the decision button BT43. In response to the operation of the enter button BT43, the quantity displayed in the quantity area AR43 is confirmed, the product registration change screen P40 is erased, and the display returns to the product registration screen. On the product registration screen displayed after deleting the product registration change screen P40, in the list item Itm of the target product, the quantity confirmed in the quantity area AR221 is indicated, and The price is displayed.

Further, when the customer cancels the registration of the target product, the customer operates the cancel button BT42. When the cancel button BT42 is operated, the product registration change screen P40 is erased, and the product registration screen returns to the displayed state. In this case, on the product registration screen displayed after the product registration change screen P40 is deleted, the list item Itm of the product "○○ chocolate" which is the object of cancellation this time is deleted.

The product registration change screen P40 is displayed in a size larger than the product registration change screen P30 of FIG. Therefore, the characters and the like on the product registration change screen P40 can be made larger than the characters on the product registration change screen P30. Also, the image operators such as the plus button BT41-1, the minus button BT41-2, the cancel button BT42, and the enter button BT43 can be made larger than the image operators on the product registration change screen P30.

As can be understood from the above description, in the present embodiment, when the mobile terminal 60 is in the cart holding state, the product registration result area AR2 on the product registration screen and the product registration change screen P40 are displayed in the handheld holding state. The mode of display is changed so that the image is enlarged more. As a result, the customer who is registering the product can change the product registration change screen P40 even if the distance between the customer and the mobile terminal 60 is long because the mobile terminal 60 is in the cart holding state. Visibility and operability can be prevented from being impaired.

In the description so far, the display mode corresponding to the hand-holding state is the standard, and the display mode corresponding to the cart holding state is an enlarged version of the standard. It may be relative which of the display modes is the standard. In other words, the display mode corresponding to the cart holding state may be treated as standard, and the display mode corresponding to the handheld holding state may be treated as being reduced from the standard.

[Modification of Embodiment]
A modification of this embodiment will be described. The product registration result area AR2 in the present embodiment is displayed so as to be enlarged in the cart holding state as compared to the handheld holding state. In addition, in the above-described embodiment, the product registration change screen P40 is displayed on the product registration screen according to the operation on the quantity area AR221 in the product registration result area AR2.
On the other hand, in the modified example of the present embodiment, the product registration result area AR2 is configured to allow an operation to change the registered content of the product. In this case, the customer can change the registered content of the registered product while the product registration screen is displayed without displaying the product registration change screen P40.

FIG. 14 shows a mode example of the product registration result area AR2 as a modification of this embodiment. The product registration result area AR2 in the figure corresponds to the cart holding state. In this modification, the product registration result area AR2 in the holding state may be similar to that shown in FIG.
In the list item Itm of the product registration result area AR2 in the figure, the product name and price are displayed, and a quantity change area AR222, a cancel button, and BT52 are arranged.
The quantity change area AR222 is an area where an operation is performed to change the registered quantity of the corresponding product. A quantity area AR52, a plus button BT51-1, and a minus button BT51-2 are arranged in the quantity change area AR222.
The customer can change the registered quantity of the corresponding product by operating the plus button BT51-1 and the minus button BT51-2. In this case, the plus button BT51-1 and minus button BT51-2 are operated to change the registered quantity, and the price shown in the same list item Itm is updated to the price corresponding to the changed registered quantity. The registration quantity may be fixed at
Also, the customer can cancel the registration of the corresponding product by operating the cancel button and BT52. In this case, in response to the operation of the cancel button and BT 52, a confirmation screen is displayed for the customer to confirm the cancellation. If the customer can cancel the product, the customer performs a cancellation instruction operation on the confirmation screen. In response to the cancellation instruction operation being performed, the confirmation screen is erased and the product registration screen is displayed again. In the product registration result area AR2 of the displayed product registration screen, the list item Itm corresponding to the product to be canceled this time has been deleted.

It should be noted that, in the imaged image area AR1 on the product registration screen as well, the mode may be changed between the hand-holding state and the cart-holding state. As an example, in the cart holding state, a message such as "please scan the barcode" displayed in the captured image area AR1 of FIG. The display of the frame and the like may be displayed in a larger size than in the hand-holding state so as to improve visibility. At this time, the magnification of the captured image may be set to be different from that in the hand-holding state so that the product code can be easily placed within the frame.

[Example of processing procedure]
An example of a processing procedure executed by the mobile terminal 60 in relation to display of the product registration screen will be described with reference to the flowchart of FIG. 15 . The process shown in the figure is executed during product registration (from the start of display of the product registration initial screen until the operation of instructing shift to payment). 13 corresponds to the case where the product registration change screen P40 of FIG. 13 is displayed in accordance with the operation on the quantity area AR221 in the cart holding state.

Step S<b>101 : During product registration, the mobile terminal 60 determines whether or not the current holding state is the cart holding state based on the detection signal of the motion sensor in the sensor section 608 .

Step S102: When it is determined that the cart is in the holding state, the portable terminal 60 displays the product registration screen in the enlarged product registration result area AR2 as shown in FIG. 11B. In the following description, the product registration screen in the expanded product registration result area AR2 is also referred to as an enlarged product registration screen.

Step S103: If it is determined in step S101 that the mobile terminal 60 is in the handheld holding state instead of the cart holding state, the portable terminal 60 is displayed in a standard size, as shown in FIGS. A product registration screen is displayed in the product registration result area AR2. In the following description, the product registration screen in the standard size product registration result area AR2 is also referred to as the standard product registration screen.

Step S104: After the process of step S102 or step S103, the mobile terminal 60 determines whether or not the quantity area AR221 in any of the list items Itm on the currently displayed product registration screen has been operated.

If it is determined in step S104 that the quantity area AR221 has not been operated, the process returns to step S101.
When the process is returned to step S101, if there is no change in the holding state between before the process is returned to step S101 and now, the process of step S102 or step S103 is skipped and the process proceeds to step S104. you can
On the other hand, when the customer shifts the portable terminal 60 from the cart holding state to the handheld holding state at the timing when the process is returned to step S101, it is determined in step S101 that the portable terminal 60 is in the handheld holding state. . In this case, the portable terminal 60 executes the process of step S103 to change the display from the enlarged product registration screen to the standard product registration screen.
Further, when the customer shifts the portable terminal 60 from the hand-holding state to the cart holding state at the timing when the processing is returned to step S101, it is determined in step S101 that the cart is in the cart holding state. In this case, the mobile terminal 60 executes the process of step S102 to change the display from the standard product registration screen to the enlarged product registration screen.

Step S105: If it is determined in step S104 that the quantity area AR221 has been operated, the portable terminal 60 determines whether the current holding state is the cart holding state.

Step S106: When it is determined in step S105 that the cart is in the holding state, the portable terminal 60 displays the product registration change screen P40 enlarged as illustrated in FIG.

Step S107: When it is determined in step S105 that the mobile terminal 60 is in the hand held state, the mobile terminal 60 displays the standard size product registration change screen P30 illustrated in FIG.

Step S108: The mobile terminal 60 waits for an operation (change confirming operation) to confirm the change of the registered content on the product registration change screen (P30 or P40) displayed by the process of step S106 or step S107. stand by. The change confirmation operation here is either an operation of confirming (determining) the changed quantity by operating the plus button or the minus button, or an operation of confirming cancellation of the registration of the target product.

Step S109: When the change confirming operation is performed, the portable terminal 60 executes the process of confirming the changed registered contents of the target product, erases the product registration change screen that has been displayed so far, and proceeds to step S101. Return processing to .

In the process shown in the figure, even if the holding state changes while the product registration change screen is being displayed, the first displayed product registration change screen P30 and product registration change screen P40 are displayed regardless of the change in the holding state. is maintained. This takes into consideration the fact that changing the mode of the product registration change screen in accordance with the change in the holding state may rather make it difficult to operate. In some cases, the product registration change screen may be changed according to changes in the holding state.

<Modification>
Modifications of this embodiment will be described below. Modifications described below may be appropriately combined with the above embodiment and other modifications.

[First modification]
As described above, after completing the product registration using the mobile terminal 60, the customer performs the payment shift instruction operation (operation on the payment shift instruction button BT15) to display the code screen on the mobile terminal 60. , the payment can be started by causing the payment device 40 to read the code displayed on the code screen.
In order for the settlement device 40 to read the code, the customer holds the portable terminal 60 in his/her hand and holds the code displayed on the display unit 405 of the portable terminal 60 over the scanner unit 406 of the settlement device 40. Become. Therefore, when the portable terminal 60 in the cart holding state is instructed to shift to settlement, the customer needs to remove the portable terminal 60 from the holder 71 of the shopping cart 70 and hold it after the shift to settlement instruction. There is At this time, the portable terminal 60 changes from the cart holding state to the handheld holding state after the settlement transfer instruction operation.

Therefore, when the mobile terminal 60 of the present modification determines that the cart is in the holding state when the payment transfer instruction operation is performed, in the message area AR3 of the code screen displayed in response to the payment transfer instruction operation, As shown in FIG. 16, a message different from that shown in FIG. 10(D) is displayed.
In the message area AR3 in FIG. 16, it is displayed that "I will make the payment machine read the following code, so please pick up your smartphone." In other words, in the message area AR3 of FIG. 16, a message is displayed to guide the customer to remove the portable terminal 60 from the holder 71 and hold it in his or her hand before allowing the settlement device 40 to read the code. ing.
When the customer removes the portable terminal 60 from the holder 71 and holds the portable terminal 60 in the display state of FIG. When determining that the mobile terminal 60 has changed to the hand held state in this way, the mobile terminal 60 may change the display of the message area AR3 on the code screen to, for example, the display of FIG. 10(D).
In addition, in this modification, when an instruction to shift to settlement is performed in the holding state, a message area AR3 having the same content as in FIG. 10D is displayed from the start of displaying the code screen. you can

[Second modification]
Next, a second modified example will be described. In this modified example, as a self-service operation in the store, a sales floor for selling by weight by a self-service system is provided, in which a customer sets a price using a weighing and pricing device and registers the product.
A weighing and pricing device measures the weight of a product to be registered placed on a scale, and uses information such as the unit weight of the measured product to determine the price of the product according to the measured weight. Then, product registration is performed.
As for a store where such a self-service weighing and pricing apparatus is used, the procedure for product registration and the associated processing in the shopping system are different from those in the previous embodiment. This point will be described below.

First, an example of a procedure for product registration by a customer at a counter where a weighing and pricing apparatus is used will be described.
When a customer wants to purchase a product sold by weight, the customer first uses his or her mobile terminal 60 to input the item of the product to be purchased in the following manner.
FIG. 17 shows an example of how commodities sold by weight are displayed in a store. In the example shown in the figure, lemons LM, apples AP, and oranges OG are displayed as products sold by weight. Merchandise information panels 3000-LM, 3000-AP, and 3000-OG are installed corresponding to the displayed lemons LM, apples AP, and oranges OG. The product information panels 3000-LM, 3000-AP, and 3000-OG are referred to as the product information panel 3000 unless otherwise distinguished.

The product information panel 3000 presents information on corresponding products. In the figure, the merchandise information panel 3000-LM is shown enlarged. In this way, on the product information panel 3000-LM, the item of the product is lemon, the unit price per unit weight, and the product information code 3001 are presented as product information. The product information code 3001 is a bar code (one-dimensional code) in the example shown in FIG. The product information code 3001 includes the product code of the product item as lemon.
Similarly, on the other product information panel 3000, the item of the product, the unit price per unit weight, and the product information code are presented as product information.

The product information panel 3000 may present product information by being displayed by a display device. Alternatively, the product information panel 3000 may present product information by attaching a printed matter such as a poster.

When entering the item of the product to be purchased, the customer displays the product registration screen on his/her mobile terminal 60 and inputs the product information code presented on the product information panel 3000 of the product to be purchased to the mobile terminal 60. make it read. This figure shows how the customer causes the product information code 3001 corresponding to the lemon LM to be read. An imaged image area AR1 on the product registration screen of the portable terminal 60 shows how the product information code 3001 is imaged.
When the code scanning of the product information code 3001 corresponding to the lemon LM is performed in this way, the portable terminal 60 acquires the product information of the lemon LM from the read product information code 3001 . The mobile terminal 60 uses the acquired product information to specify the lemon LM as the item of the product sold by weight.

A product registration result area AR2 is arranged on the product registration screen. The product registration result area AR2 shows the current registration status of the product to be purchased. In the figure, an approximate calculation area AR21 and list items Itm are arranged in the product registration result area AR2. In the figure, three list items Itm-1, Itm-2, and Itm-3 corresponding to yogurt, apple AP, and lemon LM are arranged as list items Itm.
In this case, yogurt is not a commodity sold by weight. Therefore, in the yogurt list item Itm-3, the display of "x1" in the quantity area AR221 indicates that one item has been registered and that the price is 160 yen. .
On the other hand, for each of the apple AP and lemon LM products sold by weight, the products to be purchased are in the state of "temporary registration" (temporary registration state). A provisionally registered product is a product whose item has been entered but whose pricing has not yet been completed (also in a state of waiting for weighing).
Therefore, in list items Itm-1 and Itm-2 of apple AP and lemon LM, the quantity area AR221, for example, "weighing required" indicates that pricing by weighing has not yet been performed. Along with this, in the list items of apple AP and lemon LM, the display of "??? yen" indicates that the price is undetermined. A predetermined background color indicating the temporary registration status is set for the list items Itm-1 and Itm-2.

In the example shown in the figure, the customer has provisionally registered lemon LM and apple AP as products sold by weight. In this case, the items that the customer specified for purchase by weight were the lemon LM and the apple AP. The customer in this case weighs each of the lemon LM and the apple AP. Therefore, the customer picks out the quantity (number) that he/she wants to purchase from the displayed lemons LM and apples AP. Then, the customer brings the taken out lemon LM and apple AP, and goes to the weighing and pricing device.

The weighing and pricing device that the customer visited was in a standby mode waiting for the start of weighing according to one transaction because it was not operating in response to the operation of another customer. . The weighing and pricing apparatus in the standby mode causes the display unit to display the pricing operation screen in the initial state.

FIG. 18 shows an example of the pricing operation screen in the initial state. A weighing result area AR61 is arranged on the pricing operation screen of FIG. The weighing result area AR61 is an area (column) in which the weighing result of the product to be priced by weight is displayed. The weighing result area AR61 includes a weight area AR61-1, a unit weight area AR61-2, and a total amount area AR61-3.
The weight area AR61-1 is an area in which the measured weight of the bulk product to be priced is indicated.
The weight unit price area AR61-2 is an area in which the weight unit price of the bulk product to be priced is indicated.

Among products sold by weight, there are products corresponding to the number of products, in which the quantity is calculated based on the measured weight and the unit weight, and the price is calculated based on the calculated quantity and the unit price per product. . In the case of such products sold by weight corresponding to the number, the weight area AR61-1 displays the number calculated based on the measured weight and the unit weight, and the unit weight area AR61-2 displays 1 unit. A unit price per piece may be indicated.
The total amount area AR61-3 is an area showing the total amount of the prices of the mass-market commodities for which pricing has been completed so far under the same transaction.

The product selection area AR62 is an area in which a product to be priced can be selected. Four tabs TB (TB-1 to TB-4) are arranged in the product selection area AR62 of FIG. In the product selection area AR62, each tab TB is associated with a sheet on which product buttons are arranged. The tab TB can be selected by the customer's operation. The selected tab TB is highlighted with respect to the other tabs TB, and the product button BT6 arranged on the sheet of the selected tab TB is displayed in the product selection area AR62.

In the example shown in the figure, the sheet corresponding to the tab TB-1 has a product button BT6 for provisionally registered products.
On the sheet corresponding to the tab TB-2, product buttons BT6 (preset keys) for each product registered in advance in the product master are arranged in a predetermined order according to the classification of the product sold by weight.
On the sheet corresponding to the tab TB-3, product buttons for products classified as fruit are further arranged under the classification of products sold by weight in the product master.
A sheet corresponding to tab TB-4 is a tab corresponding to a sheet on which product buttons for products further classified as vegetables under the category of products sold by weight in the product master are arranged.
In this case, fruit sheets and vegetable sheets are prepared in response to the high purchase record of fruit and vegetable products among the products sold by weight.

In the pricing operation screen in the initial state, tab TB-2 is selected as shown in FIG. As a result, in the product selection area AR62, product buttons BT6 for products included in general products registered in the product master under the category of products sold by weight are arranged on the sheet corresponding to the tab TB-2.
The sheet corresponding to the tab TB-2 is an area in which a customer who does not use the mobile terminal 60 to price a product by weight selects a product to be sold by weight.

When the product sold by weight to be purchased is fruit, the customer who does not use the portable terminal 60 for product registration operates the tab TB-3 to display a sheet on which the product button BT6 for the product sold by weight of the fruit category is arranged. be able to. A customer can operate a commodity button BT6 corresponding to a commodity sold by weight to be purchased among commodity buttons BT6 arranged on the displayed sheet, and designate it as an item of the commodity to be priced.
In addition, when the bulk product to be purchased is vegetables, a customer who does not use the mobile terminal 60 for product registration operates the tab TB-4 to select the sheet on which the product button BT6 for the bulk product of the vegetable category is arranged. can be displayed. A customer can operate a commodity button BT6 corresponding to a commodity sold by weight to be purchased among commodity buttons BT6 arranged on the displayed sheet, and designate it as an item of the commodity to be priced.

A message area ARm is arranged above the product selection area AR62. The message area ARm is an area in which a message having a predetermined content corresponding to the content of the current screen is displayed. "Select The Item" is displayed in the message area ARm in FIG. That is, the message area ARm in this case displays a message guiding the customer to operate the product button BT6 for designating the item of the product to be priced.

A connection information code area AR64 is arranged on the pricing operation screen. The connection information code area AR64 is an area where the connection information code CD is displayed. Although the connection information code in the figure is a two-dimensional code, it may be a code of another format such as a bar code. The connection information code CD is control information indicating a procedure for connecting the mobile terminal 60 running the shopping application to the weighing and pricing apparatus via Bluetooth, for example.
In the connection information code area AR64, a message is displayed to guide the customer to have the portable terminal 60 read the connection information code CD.

In addition, on the pricing operation screen, a search area AR63 is arranged in which a mass-sold product can be searched by a character input operation. In the example shown in the figure, by operating the software keyboard arranged in the search area AR63 and entering the product name, etc., it is possible to search for products sold by weight.
Note that the search area AR63 does not have to be arranged on the pricing operation screen. After that, for example, the search area AR63 may be displayed in response to performing a predetermined operation on the pricing operation screen.

A customer who uses the mobile terminal 60 for product registration performs an operation to cause the mobile terminal 60 to read the connection information code CD displayed in the connection information code area AR64 at the start of registration of the bulk product to be purchased.
Upon reading the connection information code CD as described above, the portable terminal 60 establishes communication with the weighing and pricing apparatus.

When the communication with the weighing and pricing device is established, the portable terminal 60 transmits the information of the temporarily registered wholesale product to the weighing and pricing device. Specifically, the portable terminal 60 in this case transmits information on the lemon LM and the apple AP as the information on the temporarily registered sold-by-measure product.

The weighing and pricing apparatus changes the pricing operation screen from FIG. 18 to FIG. 19 in response to receiving the information on the temporarily registered bulk product. In FIG. 19, the same parts as those in FIG. 18 are given the same reference numerals, and the description thereof will be omitted as appropriate.

In the product selection area AR62 of the pricing operation screen of FIG. 19, the tab TB-1 is selected instead of the tab TB-1 selected in FIG. Two product buttons BT6 corresponding to apple AP and lemon LM are arranged on the sheet corresponding to the selected tab TB-1. The apple AP and lemon LM products sold by weight corresponding to the two product buttons BT6 are the products provisionally registered as described with reference to FIG. 17 above.
In other words, based on the information on the temporarily registered sold-by-volume product received from the mobile terminal 60, the mobile terminal 60 puts the product button BT6 for the temporarily registered sold-by-volume product in the product selection area AR62 on the sheet corresponding to the tab TB-1. display.
In this case, the arrangement order of the product buttons BT6 may correspond to the provisional registration order (reading order of product information codes).

In other words, the weighing and pricing apparatus receives information on the temporarily registered wholesale product (temporarily registered product) by establishing a connection with the mobile terminal 60 in the standby mode. When the weighing and pricing device receives the information of the provisionally registered product, if the tab TB-2 sheet (Fig. 18) is displayed on the pricing operation screen in the initial state, the product button of the provisionally registered product is displayed. The display is switched to the sheet of tab TB-1 on which BT6 is arranged (FIG. 19).

In the pricing operation screen of FIG. 19, instead of deleting the connection information code CD in the connection information code area AR64, a message such as "connected" indicates that the weighing and pricing apparatus is currently connected to the mobile terminal 60. Connection correspondence information is displayed to indicate that the connection is being made.

In addition, in the message area ARm in the figure, a message is displayed to guide the customer to operate the product button BT6 in order to specify the item of the product to be priced.

In the following description, the case where the customer performs registration by operating the pricing operation screen displayed on the weighing and pricing device will be taken as an example.
Here, the customer first registers from the Apple AP and the Lemon LM, which are in the provisionally registered state. Therefore, the customer operates the product button BT1 corresponding to the apple AP. As a result, the apple AP is designated as a pricing target.

In response to the designation of the apple AP as a pricing target, the display on the display section of the weighing and pricing device transitions from the pricing operation screen to the weighing guidance screen.
On the weighing guidance screen, although not shown, a message is displayed to guide the customer to place the item to be priced on the scale.

In the state where the weighing guidance screen is displayed, the customer puts the apple AP to be priced on the scale of the weighing and pricing apparatus.
In response to the apple AP being placed on the weighing platform, the weighing and pricing device performs pricing processing. That is, the weighing and pricing device determines the weight of the apple AP in response to determining that the measured weight of the apple AP has stabilized, and calculates the price based on the determined weight and the weight unit price.

In response to execution of the pricing process in this way, the display on the display unit transitions to the weighing result screen.
On the weighing result screen, although not shown, the weight of the weighed apple AP is displayed, as well as the price of the apple AP calculated according to the weight and the total price according to the calculated price. be.
In addition, for example, a label print button is arranged on the weighing result screen, so that an operation to issue a label print can be performed. The customer operates the label issue button. In this case, the weighing and pricing device confirms the pricing by the pricing process in response to the operation of the label issuing button, and a label (single item label).

Further, in response to the operation of the label issue button, the weighing and pricing apparatus issues the label and transmits product pricing information about the apple AP to the connected mobile terminal 60 .

Although illustration is omitted, after the label is issued, the display may be changed from the weighing result screen to the labeling guidance screen.

At the timing when the pricing result is obtained for the temporarily registered bulk product and the label is issued as described above, the weighing and pricing device transmits the product registration information of Apple AP reflecting the pricing result to the portable terminal 60. Send to
Note that the weighing and pricing apparatus may transmit the product registration information to the transaction management apparatus 20 via a communication line.

When the apple AP label is issued, the pricing operation screen is displayed again. On the displayed pricing operation screen, the product button BT1 of the apple AP displayed on the pricing operation screen of FIG. 19 is grayed out or erased, making it inoperable.

With the pricing operation screen shown in the figure displayed, the customer operates the product button BT1 for the lemon LM in order to price the lemon LM, which is still in a provisionally registered state.

After operating the product button BT11-2 corresponding to lemon LM, the customer causes the weighing and pricing apparatus to perform pricing processing and label issuance for lemon LM in the same procedure as for apple AP described above. In accordance with the issuance of the label for the lemon LM, the pricing processing (registration) for all the products sold by weight in the provisionally registered state is completed.

Upon completion of the registration of all the temporarily registered bulk products, the display of the weighing and pricing device returns to the initial pricing operation screen (FIG. 18).

Further, in response to the completion of the registration of all products sold by weight that have been in the provisionally registered state, the product registration screen displayed on the mobile terminal 60 changes to the state shown in FIG. 20, for example.
The product registration result area AR2 of the product registration screen in FIG. 17 has changed as follows in comparison with FIG. In other words, the list items Itm-1 and Itm-2 corresponding to lemon LM and apple AP have changed from the temporary registration status to the registered status. Specifically, the background color of each of the list items Itm-1 and Itm-2 is changed from the color indicating the provisional registration status to the color indicating the registered status. In addition, the price determined by the pricing process is shown in each of the list items Itm-1 and Itm-2. Also, the quantity area AR221 in each of the list items Itm-1 and Itm-2 is changed from "measurement required" to "measurement". The quantity area AR221 with "weighing" indicates that the corresponding product is sold by weight and registered by the weighing and pricing process.

When the customer registers the product for sale by weight as described above, the customer temporarily registers the product to be purchased by having the mobile terminal 60 read the product information code 3001 of the product information panel 3000 at the sales floor for the product for sale by weight. and then travel some distance to get to the weighing and pricing equipment. When moving to the weighing and pricing apparatus in this manner, the customer may attach the mobile terminal 60 to the holder 71 of the shopping cart 70 or may hold it in hand.

In this way, when the customer completes the temporary registration of the product for sale by weight and moves to the weighing and pricing apparatus, communication between the weighing and pricing apparatus and the mobile terminal 60 can be performed when the customer goes to the weighing and pricing apparatus. In order to make the connection possible, it is preferable that the portable terminal 60 displays a message to guide the portable terminal 60 to read the connection information code CD.

In this modified example, while the customer completes the temporary registration of the product for sale by weight and goes to the weighing and pricing apparatus as described above, the above guidance is displayed on the mobile terminal 60 . In addition, in this modified example, when the guidance is displayed, the content (mode) of the guidance is made different depending on whether the customer attaches the portable terminal 60 to the holder 71 of the shopping cart 70 or holds it in his/her hand.

The mobile terminal 60 of the present modification determines whether or not the provisional registration of all bulk products that the customer wants to purchase has been completed. For example, if the portable terminal 60 does not read the next product information code 3001 even after a certain period of time has elapsed since the reading of the product information code 3001 was executed, the portable terminal 60 can read all the bulk sales that the customer wants to purchase. It may be determined that the provisional registration of the product has been completed.

At this time, since the customer has not completed product registration and has not performed an instruction to shift to settlement, the mobile terminal 60 displays the message "weighing required" in the quantity area AR221, as shown in FIG. 17, for example. is displayed on the product registration screen including the list item Itm of the product sold by weight.

In response to determining that the provisional registration of the bulk product has been completed, the portable terminal 60 determines whether the current self-holding state is the cart holding state or the handheld holding state.
When determining that the cart is in the holding state, the portable terminal 60 displays the following message on the product registration screen, for example.
Specifically, for example, the mobile terminal 60 is removed from the holder 71 of the shopping cart 70 and held by hand to connect the weighing and pricing apparatus to the mobile terminal 60 so as to be able to communicate with the weighing and pricing apparatus. , a message is displayed to guide the portable terminal 60 to read the connection information code CD displayed on the display portion of .
On the other hand, when it is determined that the portable terminal 60 is held in hand, the portable terminal 60 simply reads the connection information code CD displayed on the display section of the weighing and pricing apparatus with the portable terminal 60 currently held in the hand. display a message that guides you to
The display of such a message may be displayed as a pop-up screen or the like superimposed on the product registration screen. A pop-up screen may be erased, for example, by operating a confirmation button arranged on the pop-up screen. Alternatively, the pop-up screen may be deleted when the portable terminal 60 and the weighing and pricing device are communicably connected.

[Third Modification]
Regardless of the holding state of the mobile terminal 60, the screen change control may be stopped and the screen may be fixed in the standard state or the enlarged display state.
For example, as an operation for the mobile terminal 60, a display fixing operation for fixing the screen state to the current screen state may be enabled. If the display fixing operation is performed while the screen is currently displayed in the standard state, mobile terminal 60 fixes the display in the standard state thereafter regardless of the change in the holding state. For example, depending on the customer, regardless of whether the customer is in a hand-held state or a cart-held state, the customer may want to always display as much information as possible, such as a list of registered products, on one screen. There is In such a case, the screen should be fixed in the standard state. Therefore, in this case, the customer should perform the display fixation operation when the screen is displayed in the standard state by hand-holding.
In addition, if the display fixing operation is performed while the mobile terminal 60 is currently in the enlarged display state, the mobile terminal 60 fixes the enlarged display state thereafter regardless of the change in the holding state. Even in a situation where the product is registered with the mobile terminal 60 in a cart holding state, for example, in the case of a product weighing several kilograms, such as a bag of rice, the customer may temporarily In some cases, it is better to remove the terminal 60 from the holder 71 and hold the terminal 60 in the hand so that the product code attached to the product is read by the portable terminal 60 . In some cases, it may be annoying for the customer that the display on the screen changes to the standard state when the device is temporarily held in the hand. In such a case, the customer can perform the display fixing operation while the enlarged display is being performed while holding the cart so that the enlarged display can be maintained even when the customer is holding the cart.
After the display is fixed by the display fixing operation as described above, the display fixation may be released according to an operation for instructing release of the display fixation, for example.

Also, for example, from the start of the product registration operation corresponding to one item until the completion or cancellation of the product registration operation, regardless of the holding state, for example, when the product registration operation is started The display state (standard state or enlarged display state) may be fixed.

[Fourth Modification]
In the display of the product registration screen in either the standard state or the enlarged display state, the product registration result area AR2 may be hidden and only the captured image area AR1 may be displayed.
For example, if the customer does not often check the product registration result when the cart is held, the product registration result area AR2 may be hidden and only the captured image area AR1 may be displayed when the cart is held. In this case, the product registration result area AR2 in an enlarged display state may be displayed by the customer's operation, for example.
On the other hand, if the customer does not check the product registration result much in the holding state, the product registration result area AR2 may be hidden and only the captured image area AR1 may be displayed in the holding state. good. In this case, for example, the product registration result area AR2 in the standard state may be displayed by the customer's operation.

[Fifth Modification]
The shopping cart 70 is equipped with a rechargeable battery so that the portable terminal 60 attached to the holder 71 can be charged. Therefore, if the customer charges the mobile terminal 60 with the charging battery while the mobile terminal 60 is in the cart holding state, the stored power of the built-in battery of the mobile terminal 60 can be prevented from decreasing. On the other hand, when the portable terminal 60 is in the holding state, it may be difficult to connect the charging battery of the shopping cart 70, so the power stored in the built-in battery of the portable terminal 60 decreases.

When the captured image area AR1 is displayed on the product registration screen displayed on the mobile terminal 60, the power consumption is relatively large because the imaging unit 606 (camera) is activated. Therefore, when the product registration screen is displayed without being charged from the outside, the degree of decrease in the stored power of the built-in battery of the mobile terminal 60 also increases.

Therefore, the portable terminal 60 of this modified example changes the display mode of the captured image area AR1 as follows, depending on whether the current holding state is the cart holding state or the handheld holding state.

When the mobile terminal 60 is in the cart holding state, the captured image area AR1 in which captured images are constantly displayed is displayed on the product registration screen. That is, when the cart is held during product registration, the portable terminal 60 is in a state in which the imaging unit 606 is constantly activated. In this case, the power consumption of the mobile terminal 60 is high, but since the charging battery of the shopping cart 70 can be charged in the cart holding state, the decrease in the remaining amount of the built-in battery of the mobile terminal 60 is avoided. be able to.

On the other hand, when the mobile terminal 60 is held in hand, the captured image is displayed in the captured image area AR1 when the customer reads the product code for product registration. The captured image is not displayed in the image area AR1. For this purpose, when the customer causes the portable terminal 60 to read the product code, the customer should perform an operation for activating the imaging unit 606 on the product registration screen. In addition, the activation and deactivation of the imaging unit 606 after reading the product code may be performed by the customer's operation, for example. Alternatively, after the portable terminal 60 reads the code of the product, activation of the imaging unit 606 may be stopped in response to a certain period of time having passed without the code of the product being imaged.
In the hand-holding state, charging from the rechargeable battery may not be possible, but by doing as described above, the imaging unit 606 can be activated only when reading the code of the product. This makes it possible to reduce the power consumption of the built-in battery of portable terminal 60 in the hand held state.

[Sixth Modification]
Contrary to the fifth modification, in the cart holding state, the captured image area AR1 is normally hidden, and when the customer reads the product code for product registration, the camera can be activated. , the captured image may be displayed in the captured image area AR1, and the captured image area AR1 may be constantly displayed in the holding state.
For example, shopping using a shopping cart with the mobile terminal 60 in the cart holding state tends to take a long time. In this case, in stores where the shopping cart is not equipped with a charging battery, the battery of the mobile terminal 60 will be consumed a lot if the captured image area AR1 is constantly displayed. In such a case, if the customer activates the camera to display the captured image area AR1, it is possible to reduce power consumption of the battery during shopping.
On the other hand, when the portable terminal 60 is used in a hand-held state, it can be said that there is a tendency for shopping at a convenience store or the like for a short period of time, for example. In this case, since the mobile terminal 60 consumes less power when registering the product, it can be considered that it is preferable to constantly display the captured image area AR1.

[Seventh Modification]
It should be noted that part of the processing executed by the mobile terminal 60 in the above-described embodiment may be performed by, for example, the transaction management device 20, the registration and settlement device 30, the settlement device 40, the transaction status management device 50, the store controller 10, and other higher-level stores in the store. It may be executed by a device, a server device on a cloud, or the like. Similarly, part of the processing executed by each of the transaction management device 20, the registration settlement device 30, the settlement device 40, the transaction status management device 50, the store controller 10, etc. may be executed by another device.
As one of the aspects as described above, the shopping system of the present embodiment may be provided with a configuration of a thin client system. As an example, transaction management device 20 or another server may be configured as a thin client compatible server device (for example, a cloud server), and portable terminal 60 or the like may function as a thin client.
In this case, for example, the cloud server uses the detection signal of the sensor unit 608 transmitted from the mobile terminal 60 to determine whether the mobile terminal 60 is held in a cart or in a hand held state. may be configured to run
Further, the transaction management device 20, the transaction status management device 50, the store controller 10, etc. may be distributed over a plurality of computer devices or servers.
