Description

[Technical field]

[0001] The present invention relates to a display device, a display method, and a display program used in a store or the like to check for missed product registrations. [Background technology]

[0002] Self-checkout systems, which allow users to register the products they wish to purchase and make payments, are being introduced in convenience stores, supermarkets, and other stores. However, when users who are unfamiliar with self-checkout systems purchase products, they often forget to register the products. In other words, products may not be registered in the self-checkout system.

[0003] One example of a system that can prevent product registration omissions is the scan check system. Fig. 12 is an explanatory diagram showing an example of a general scan check system. The scan check system shown in Fig. 12 is composed of a POS (Point of Sale) system and a check device.

[0004] The POS system may store past purchase data. The POS system may also be a cloud-based POS system in which data is stored in a location separate from the POS main unit.

[0005] Fig. 13 is an explanatory diagram showing an example of products in a basket. The basket shown in Fig. 13 contains four pieces of meat and four pieces of fish as products.

[0006] The user registers the items in the basket into the POS system either manually or by using an attached scanner, and the POS system transmits the registered item information to the check device.

[0007] Next, the check device displays the transmitted product information on a display etc. The employee checks based on the displayed information whether the product in the basket has been registered or not.

[0008] For example, Patent Document 1 describes a check device and a check system that can efficiently check for product registration omissions by users. The check device described in Patent Document 1 includes a control device that determines the number of checks for registration omissions, and a display device that displays the determined number of checks.

[0009] [Patent Document 1] JP 2023-173953 A Summary of the Invention [Problem to be solved by the invention]

[0010] When using the checking device described in Patent Document 1, an employee basically checks whether or not each product has been registered (registration omission).

[0011] Fig. 14 is an explanatory diagram showing an example of a product check by an employee in the scan check system. In the example shown in Fig. 14, only two pieces of meat were registered, so the remaining two pieces of meat are marked as "NG products" because they were not registered.

[0012] In the example shown in Fig. 14, the control device described in Patent Document 1 determines the number of unregistered checks to be "2." In addition, the display device described in Patent Document 1 displays the determined number of checks, "2."

[0013] That is, as shown in Figure 14, the employee decides to "check two items for this customer" in order to check two items out of eight items. Next, the employee randomly selects two items out of the eight items to check.

[0014] However, when choosing two products from eight products, the probability that at least one of the selected products will be an unacceptable product is 1-6 / 8*5 / 7=13 / 28 ≒ 0.46. In other words, the probability that an unacceptable product will be discovered under the above conditions is approximately 46%, so even if employees are notified of the number of unregistered checks, it is not guaranteed that they will be able to check all of the unacceptable products.

[0015] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a display device, a display method, and a display program that enable an employee to more reliably check for any missed product registrations by a user. [Means for solving the problem]

[0021] [Configuration Description] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals, and the description thereof will be omitted or simplified as appropriate. In addition, the shape, size, arrangement, etc. of the configurations shown in each drawing may be changed as appropriate within the scope of the present invention.

[0022] 1 is an explanatory diagram showing an example of a check system according to an embodiment of the present invention. The check system 10 according to the present embodiment is used in a retail store such as a convenience store or a supermarket.

[0023] 1, the check system 10 of this embodiment is composed of a POS terminal 100, a management server 200, and a check device 300. The POS terminal 100, the management server 200, and the check device 300 are connected to each other so as to be able to communicate wirelessly via a LAN (Local Area Network) or the Internet.

[0024] The POS terminal 100 and the check device 300 may be connected to each other so as to be capable of wireless communication via Bluetooth (registered trademark) or NFC (Near Field Communication).

[0025] The POS terminal 100 is a terminal used by a user who visits a store to shop and registers and settles for products by himself / herself. The POS terminal 100 is, for example, a dedicated POS terminal, a PC (Personal Computer), a tablet, or a smartphone.

[0026] The POS terminal 100 has the function of a POS register that registers products purchased by a user, settles the bill, and settles the payment. The POS terminal 100 of this embodiment is, for example, a tablet mounted on a shopping cart shown in Fig. 1. A user uses the POS terminal 100 to register products in the check system 10 while shopping.

[0027] Although only one POS terminal 100 is shown in FIG. 1, the check system 10 may include multiple POS terminals 100.

[0028] The management server 200 is a POS server that manages user information of users who use the store and registration information of products registered by the users.

[0029] The check device 300 is an information terminal such as a tablet or a smartphone operated by a store employee, for example. The check device 300 is used by the employee to check whether a user has failed to register a product.

[0030] In this embodiment, the "check for missing product registration" corresponds to the following series of operations: First, the employee selects a product to be checked from multiple products in the basket, and uses the check device 300 to read the barcode of the selected product.

[0031] Next, the check device 300 judges whether the product whose barcode was read is a registered product or not, and displays the judgment result. Finally, the employee checks whether the user has omitted registering the product based on the displayed judgment result.

[0032] Next, the reason why an employee using the check system 10 of this embodiment can more reliably check for omissions in product registration by a user will be described with reference to Figures 2 and 3. Figure 2 is an explanatory diagram showing an example of product check by an employee in the check system 10 of this embodiment.

[0033] The products in the basket shown in Fig. 2 are the same as the products in the basket shown in Fig. 14. The unacceptable products shown in Fig. 2 are the same as the unacceptable products shown in Fig. 14.

[0034] An employee using the check system 10 of this embodiment can check whether a product has been registered for each category to which the product belongs (registration omission). For example, in the example shown in Fig. 2, the category to which the product in the basket belongs is either "meat" or "fish".

[0035] Therefore, the check device 300 of the check system 10 of this embodiment displays that two products belonging to the category "meat" are registered, and four products belonging to the category "fish" are registered.

[0036] The employee, looking at the displayed information, determines that "2 pieces of meat and 4 pieces of fish are registered," as shown in Figure 2. Next, the employee checks each of the 4 pieces of meat in the basket that do not match the registered numbers.

[0037] If two meats are checked consecutively from four meats, the probability that at least one of the two checked meats is a prohibited product is 1-2 / 4*1 / 3=5 / 6≒0.83. In other words, the probability of discovering a prohibited product under the above conditions increases to approximately 83%.

[0038] Therefore, an employee using the check system 10 of this embodiment can more reliably check for omissions in product registration by a user than when using the check device described in Patent Document 1.

[0039] 3 is an explanatory diagram showing another example of product check by an employee in the check system 10 of the present embodiment. The basket shown in Fig. 3 contains two pieces of meat and four pieces of fish as products. The unacceptable products are the two pieces of meat.

[0040] In the example shown in FIG. 3, the check device 300 of the check system 10 of this embodiment displays that 0 products belonging to the category "meat" are registered, and 4 products belonging to the category "fish" are registered.

[0041] The employee, referring to the displayed content, determines that "0 pieces of meat are registered," as shown in Figure 3. Next, the employee checks each of the two pieces of meat in the basket that have a registered quantity of 0.

[0042] It is difficult for an employee to find a category that has zero registered products from a registration list that shows a list of registered products. However, the checking device 300 of this embodiment can display categories with zero registered products according to a predetermined condition. The predetermined condition is, for example, that the loss rate of products belonging to the category is higher than a predetermined standard.

[0043] If an employee finds an item in the basket that belongs to a category with zero registered items, he or she can immediately select the item as an item to be checked, knowing for certain that it is an unacceptable item. In other words, in cases like the example shown in Figure 3, it is considered to be particularly advantageous to display the number of registered items for each category to which the item belongs.

[0044] As described above, the check system 10 of the present embodiment provides a UI (User Interface) that indicates the number of products in the basket registered for each category to which the products belong. The UI provided by the check system 10 assists employees in visually selecting products to be checked.

[0045] Therefore, an employee using the checking system 10 of this embodiment selects products to be checked using the number of registered products for each category, thereby increasing the rate of discovering non-compliant products compared to when products to be checked were randomly selected from the products in the basket.

[0046] As described above, the check system 10 of the present embodiment can provide employees with a new judgment criterion, namely, a category in which the number of registered products is zero, that is, a no-product-registered category.

[0047] 4 is a block diagram showing an example of the configuration of the check system 10 of this embodiment. As shown in FIG. 4, the POS terminal 100 includes a POS terminal control unit 110, a POS terminal display unit 120, a POS terminal operation unit 130, a POS terminal reading unit 140, and a POS terminal communication unit 150.

[0048] The POS terminal 100 includes a processor such as a CPU (Central Processing Unit) and a memory such as a RAM (Random Access Memory). Each part of the POS terminal 100 is a functional part that is realized by the processor executing a program stored in the memory.

[0049] At least one of the components of the POS terminal 100 may be implemented by a processing circuit such as an Application Specific Integrated Circuit (ASIC) or a Field Programmable Gate Array (FPGA).

[0052] The product registration unit 111 also has a function of determining whether or not a product whose barcode has been read by the POS terminal reading unit 140 is an age-restricted product. Age-restricted products include, for example, alcoholic beverages and tobacco.

[0053] When the product whose barcode has been read by the POS terminal reading unit 140 is an age-restricted product, the product registration unit 111 notifies the POS terminal display control unit 113 that the product is an age-restricted product.

[0054] The payment processing unit 112 has a function of performing payment processing for products that have been registered and paid for in the product registration unit 111. The POS terminal 100 of this embodiment is capable of performing payment by prepaid card, credit card, electronic money, or barcode.

[0055] When the user selects payment by prepaid card, credit card, electronic money, or barcode, the payment processing unit 112 performs payment processing based on the input information of the prepaid card, credit card, electronic money, or barcode.

[0056] The POS terminal display control unit 113 has a function of controlling the POS terminal display unit 120. Specifically, the POS terminal display control unit 113 causes the POS terminal display unit 120 to display information about the product read by the POS terminal reading unit 140, information about the settlement of the product, information about the payment, and the like.

[0057] Furthermore, if the product read by the user is an age-restricted product, the POS terminal display control unit 113 notifies the user that the product is an age-restricted product via the POS terminal display unit 120, based on the notification from the product registration unit 111. Next, the POS terminal display control unit 113 causes the POS terminal display unit 120 to display a screen for age verification.

[0058] The POS terminal display unit 120 has a function of displaying information on registered products, information on product settlement and payment, a screen for age verification, etc. The POS terminal display unit 120 is, for example, a liquid crystal display.

[0059] The POS terminal operation unit 130 is operated by a user. When operated by a user, for example, a payment instruction, a selected payment method, and information for payment (such as a personal identification number) are input. but The data is input from the POS terminal operation unit 130. The POS terminal operation unit 130 is, for example, a touch panel formed integrally with the POS terminal display unit 120.

[0060] The POS terminal reading unit 140 has a function of irradiating a laser scanning line onto a product and reading a barcode attached to the product. Product information read by the POS terminal reading unit 140 is input to the POS terminal control unit 110.

[0061] The POS terminal reading unit 140 may also include a card reader for reading information on a prepaid card or credit card, a scanner for reading information on electronic money or a barcode, or a camera.

[0062] The POS terminal communication unit 150 transmits information on the products registered by the user as registration information to the management server 200. The POS terminal communication unit 150 is a network interface that transmits and receives data to and from the management server 200 via, for example, wireless communication.

[0063] 4, the management server 200 includes a management server communication unit 210, a management server control unit 220, a user information storage unit 230, and a registration information storage unit 240. The management server 200 also includes a processor such as a CPU, and a memory such as a RAM.

[0064] The management server communication unit 210 receives registration information from the POS terminal 100. In addition, the management server communication unit 210 receives from the check device 300 the POS identification number, the user identification number, and the check result.

[0065] Moreover, the management server communication unit 210 transmits the registration list to the check device 300. The management server communication unit 210 is a network interface that transmits and receives data to and from the POS terminal 100 and the check device 300, for example.

[0066] The POS identification number is a number unique to the POS terminal 100. The user identification number is a membership number assigned to each user registered in the store.

[0067] When the management server control unit 220 receives the POS identification number from the check device 300, it extracts the registration list corresponding to the received POS identification number from the registration information storage unit 240. Next, the management server control unit 220 transmits the extracted registration list to the check device 300 via the management server communication unit 210.

[0068] The user information storage unit 230 has a function of storing user information of users who use the store. The user information includes a user identification number, name, address, age, and payment information.

[0069] The user information is information that is input in advance by a user and stored in the user information storage unit 230. The user information storage unit 230 also stores the check result for unregistered products received from the check device 300 as a check history.

[0070] The check history is the past check results of the user. For example, the check history includes the total number of checks and the number of times registration omissions were found in the past year.

[0071] The registration information storage unit 240 has a function of storing registration information received from the POS terminal 100. The registration information includes information such as the category (department) to which the product belongs, the product code, the product name, the number of products, and the price.

[0072] The categories are, for example, meat, fresh fish, frozen food, seasonings, and sweets, but in this embodiment, there are many other categories.

[0073] The registration information storage unit 240 stores the registration information of multiple products in one shopping session of the user as one registration list. The registration information storage unit 240 may also store information such as the purchase store and the purchase date and time in the registration information.

[0074] As shown in FIG. 4, the checking device 300 includes a checking device control unit 310 , a checking device communication unit 320 , a checking device reading unit 330 , a checking device operation unit 340 , and a checking device display unit 350 .

[0075] The check device 300 includes a processor such as a CPU and a memory such as a RAM. Each unit of the check device 300 is a functional unit that is realized by the processor executing a program stored in the memory. At least one of the units of the check device 300 may be realized by a processing circuit such as an ASIC or an FPGA.

[0076] As shown in FIG. 4, the check device control unit 310 includes an information acquisition unit 311 , a display number determination unit 312 , a omission determination unit 313 , a product addition unit 314 , and a check device display control unit 315 .

[0077] The information acquisition unit 311 has a function of acquiring the registration list from the management server 200. The information acquisition unit 311 inputs the acquired registration list to the display count determination unit 312.

[0078] The information acquisition unit 311 also has a function of acquiring the POS identification number of the POS terminal 100 .

[0079] For example, the information acquiring unit 311 may acquire the POS identification number from information of a barcode attached to the POS terminal 100 that is read by the check device reading unit 330. The information acquiring unit 311 may also acquire the POS identification number that is input via the check device operating unit 340.

[0080] The display number determination unit 312 has a function of determining, for each category, the display number, which is the number of registered products to be displayed by the check device display unit 350. The display number determination unit 312 of this embodiment determines the display number based on the registration list acquired by the information acquisition unit 311.

[0081] Specifically, the display number determination unit 312 determines the number of products included in a registration list, i.e., the display number, which is the number of registered products, for each category based on the categories and the number of products included in one registration list. Next, the display number determination unit 312 inputs each determined display number to the check device display control unit 315.

[0082] The omission determination unit 313 has a function of determining whether or not a product whose barcode has been read by the check device reading unit 330 is included in the registration list.

[0083] If the product whose barcode is read by the check device reading unit 330 is not included in the registration list, the omission determination unit 313 determines that the product is an unregistered product (NG product). The omission determination unit 313 also inputs the determination result to the product addition unit 314 and the check device display control unit 315.

[0084] The product addition unit 314 has a function of adding a product that has been determined to be an unregistered product to the registration list when the user decides to add the unregistered product to the registration list.

[0085] If it is determined that the product should be added to the registration list, the product addition unit 314 adds the unregistered product to the registration list. Next, the product addition unit 314 transmits the registration list to which the unregistered product has been added to the management server 200 via the check device communication unit 320.

[0086] The check device display control unit 315 has a function of controlling the display contents of the check device display unit 350. Specifically, the check device display control unit 315 generates a check screen (see FIGS. 6 to 9 described later) that is used when an employee checks for omissions in product registration. Next, the check device display control unit 315 causes the check device display unit 350 to display the generated check screen.

[0087] The check screen generated by the check device display control unit 315 includes the registration list, the display number determined by the display number determination unit 312, and the determination result by the leakage determination unit 313. In other words, the check device display control unit 315 displays the registration list, the display number, the determination result, and the like on the check screen.

[0088] The check device communication unit 320 transmits the POS identification number to the management server 200. Next, the check device communication unit 320 receives the registration list from the management server 200. The check device communication unit 320 is, for example, a network interface that transmits and receives data to and from the management server 200 via wireless communication.

[0089] The check device reading unit 330 has a function of irradiating a laser scanning line onto a commodity and reading a barcode attached to the commodity. The commodity information read by the check device reading unit 330 is input to the check device control unit 310.

[0090] The check device reading unit 330 may be equipped with a card reader for reading information on a prepaid card, a scanner for reading information on a barcode, or a camera.

[0091] The check device operation unit 340 is, for example, a touch panel formed integrally with the check device display unit 350. An employee operates the check device operation unit 340 to input a POS identification number or a user identification number, or to add or cancel a product that has not been registered.

[0092] The check device display unit 350 has a function of displaying a check screen used when an employee checks for omissions in product registration. The check device display unit 350 is, for example, a liquid crystal display.

[0093] A user who uses the above-described check system 10 reads the barcode of a product that the user wishes to purchase using the POS terminal 100. By reading the barcode, the user registers the product that the user wishes to purchase in the check system 10.

[0094] The POS terminal 100 transmits the information on the registered product as registration information to the management server 200. The transmitted registration information is stored in the registration information storage unit 240 of the management server 200.

[0095] By repeating the above process, multiple pieces of registration information are accumulated in the registration information storage unit 240. That is, a registration list is generated in the registration information storage unit 240. After finishing their shopping, the user moves to a payment area in the store to make payment.

[0096] In the payment area, before the payment is made, an employee uses the check device 300 to check whether any products have been registered. After the check is completed, the payment is made.

[0097] [Explanation of operation] The following describes the operation of the check device 300 of this embodiment. Fig. 5 is a flowchart showing the operation of the omission of registration confirmation process performed by the check device 300 of this embodiment.

[0098] First, the information acquisition unit 311 of the check device control unit 310 acquires the POS identification number of the POS terminal 100 (step S101).

[0099] Next, information acquiring unit 311 transmits the acquired POS identification number to management server 200. Next, information acquiring unit 311 receives from management server 200 a registration list corresponding to the transmitted POS identification number.

[0100] That is, the information acquisition unit 311 acquires the registration list from the management server 200 (step S102). Next, the information acquisition unit 311 inputs the acquired registration list to the display count determination unit 312.

[0101] Next, the display number determination unit 312 determines the display number, which is the number of registered products, for each category based on the categories and product numbers included in the registration list (step S103). Next, the display number determination unit 312 inputs each determined display number to the check device display control unit 315.

[0102] Next, the check device display control unit 315 generates a check screen including the determined display numbers. Next, the check device display control unit 315 causes the generated check screen to be displayed on the check device display unit 350 (step S104).

[0103] Fig. 6 is an explanatory diagram showing an example of a check screen displayed by the check device display unit 350 of this embodiment. As shown in Fig. 6, the check screen includes a registration list display section a in which a registration list is displayed, a display section b in which each determined display number is displayed, and a confirmation completion button c.

[0104] As shown in Fig. 6, the determined display numbers are displayed for each category in the display field b. In the example shown in Fig. 6, the determined display numbers for the categories of meat, fresh fish, frozen food, and seasonings are "2", "3", "0", and "1", respectively.

[0105] 6 is a button that is operated when the employee has completed checking for registration omissions. Note that the check screen of this embodiment does not have to include the confirmation completion button c. If the check screen does not include the confirmation completion button c, the employee may scan a barcode for confirmation completion when finishing the check.

[0106] The employee uses the checking device 300 to read the product to be checked (step S105). For example, from among multiple products in the shopping cart of the user, the employee selects products that belong to a category that has more products than the number of products per category displayed in the display field b.

[0107] Next, the employee reads the barcode of the selected product to be checked using the check device reading unit 330 of the check device 300. Next, the omission determination unit 313 determines whether the product whose barcode has been read is included in the registration list (step S106).

[0108] If the product whose barcode has been read is included in the registration list (Yes in step S106), the check device display control unit 315 changes the check screen so that the product to be checked can be identified and the check results by category are displayed in the display field b. Next, the check device display control unit 315 causes the check device display unit 350 to display the changed check screen (step S107).

[0109] FIG. 7 is an explanatory diagram showing another example of the check screen displayed by the check device display unit 350 of this embodiment.

[0110] For example, if the product to be checked is "product A," the color of the row displaying information about "product A" in the registration list display section a is changed to a color (e.g., black) different from the colors of the rows displaying information about other products, as shown in Fig. 7. In other words, by referring to the check screen shown in Fig. 7, an employee can easily understand that the product to be checked is a registered product.

[0111] 7, the display field b displays "Meat: 1" as the check record by category. That is, the check device display control unit 315 displays the number of products whose barcodes have been read for each category in the display field b. By referring to the check screen shown in FIG. 7, the employee can easily understand how many items have been checked for each category.

[0112] Next, the employee determines whether or not to end the check (step S112). If it is determined that the check is to be ended (Yes in step S112), the employee operates the check completion button c on the check screen. When the check completion button c is operated, the checking device 300 proceeds to the process of step S113.

[0113] If it is determined that the check should not be completed (No in step S112), the employee again scans the product to be checked (step S105).

[0114] If the read product is not included in the registration list (No in step S106), the check device display control unit 315 adds the unregistered product to the check screen, and changes the check screen so that the check results by category are displayed in the display field b. Next, the check device display control unit 315 causes the check device display unit 350 to display the changed check screen (step S108).

[0115] Fig. 8 is an explanatory diagram showing another example of the check screen displayed by the check device display unit 350 of this embodiment. For example, if the checked product is "product G" that is not included in the registration list, an unregistered product display section d is added to the check screen as shown in Fig. 8. Information on "product G" is displayed in the unregistered product display section d.

[0116] In order to make it clear at a glance that the product is an unregistered product, the unregistered product display section d is displayed with a pattern (for example, diagonal lines) that is different from the registration list display section a.

[0117] The unregistered product display section d may be displayed in a color (e.g., red) different from that of the registration list display section a. Also, only the product information displayed in the unregistered product display section d may be displayed in bold. By referring to the check screen shown in FIG. 8, the employee can easily know that there is a product that has not been registered.

[0118] Also, as shown in Fig. 8, the display field b displays "meat: 3" and "fresh fish: 1" as the check results by category. "Meat: 3" is more than the number of registrations by category "meat: 2".

[0119] Therefore, the employee can be sure that there are unregistered products among the products belonging to the category "meat." In other words, it is considered that the employee is more likely to notice unregistered products by checking the products while referring to the check records by category.

[0120] In addition, when the unregistered product display section d is added, the check device display section 350 may output a warning sound or a message to prompt the employee to check for unregistered products.

[0121] Also, as shown in FIG. 8, the unregistered product display section d includes an add button e that is operated when adding an unregistered product to the registration list, and a cancel button f that is operated when not adding the unregistered product to the registration list.

[0122] Next, the user determines whether or not to add the unregistered product to the registration list (step S109). If the user determines to add the unregistered product to the registration list (Yes in step S109), the employee operates the add button e.

[0123] When the add button e is operated, the product adding unit 314 adds the unregistered product to the registration list (step S110). Next, the product adding unit 314 transmits the registration list to which the unregistered product has been added to the management server 200 (step S111). Next, the check device 300 proceeds to the process of step S112.

[0124] If the user decides not to add the unregistered product to the registration list (No in step S109), the employee operates the cancel button f. When the cancel button f is operated, the registration list is not changed.

[0125] If the unregistered product is not added to the registration list, the unregistered product is removed from the shopping cart by the employee. Next, the checking device 300 proceeds to the process of step S112.

[0126] In step S113, the check device communication unit 320 transmits the current check result to the management server 200. When the check result is transmitted, the check device 300 ends the omission of registration confirmation process.

[0127] 6 to 8, the check device display control unit 315 of this embodiment also displays categories with a display count of 0 in the display field b of the check screen, that is, categories that are not included in the registration list, i.e., product-unregistered categories. The reason for this is that, as described above, information in which the number of registered products is 0 is considered to be the most useful information for employees.

[0128] The unregistered product category displayed by the check device display control unit 315 may be predetermined for each store. For example, a category with many unregistered products in past sales records may be predetermined as the unregistered product category. In the example shown in Figs. 6 to 8, the category "frozen" is predetermined as the unregistered product category.

[0129] In addition, the unregistered product category displayed by the check device display control unit 315 may be, for example, a category input from outside via the check device operation unit 340, or a category transmitted from another terminal that is communicatively connected to the check device 300.

[0130] 9 is an explanatory diagram showing another example of the check screen displayed by the check device display unit 350 of this embodiment. In the example shown in Fig. 9, "sweets", which is an externally input category, is set as a product unregistered category.

[0131] If the unregistered product category can be input from outside, employees can check the product according to the products sold in the store. For example, employees can respond when a product belonging to a new category is sold.

[0132] Regarding the definition of a category, the display count determination unit 312 may determine the display count by assuming that a specific product group belongs to one arbitrary category. Fig. 10 is an explanatory diagram showing an example of a product group that the display count determination unit 312 of the present embodiment has set to belong to one arbitrary category.

[0133] The two products shown in Figure 10 are products that have had a lot of loss in the past month. The categories to which the two products shown in Figure 10 belong are "meat" and "fresh fish," respectively. In other words, each of the products shown in Figure 10 would normally belong to a different retail category.

[0134] However, the display number determination unit 312 may determine the number to display by regarding, for example, the two products shown in Fig. 10 as belonging to the category "lost products". In other words, the display number determination unit 312 may determine the number to display by regarding a plurality of categories as one category. If the display number determination unit 312 can determine the number to display by regarding a specific group of products as belonging to one arbitrary category, employees can flexibly change the way of checking according to the situation of the store.

[0135] As described above, the check device display control unit 315 of this embodiment displays on the display screen (check screen) each display number, which is the number of products included in the product list determined for each category, based on a product list (registration list) consisting of multiple product information (registration information) including products and the categories to which the products belong.

[0136] 6 to 9, the check device display control unit 315 displays the name of a category together with the determined display count for that category on the display screen for each category. In addition, the check device display control unit 315 further displays the name of the no-product category together with the display count of 0 for at least one no-product category (category with no product registered) that is not included in the product list on the display screen.

[0137] The no-item category is a category that satisfies a predetermined condition, for example, that the loss rate of products belonging to the category is higher than a predetermined standard.

[0138] A category in which the percentage of lost products is higher than a predetermined standard is, for example, a category in which products are likely to be lost, or a category containing a group of products in which losses have been found based on past purchasing data.

[0139] The predetermined condition may be that the unit price of the products in the category is higher than a predetermined value, or that the positions of the barcodes on the products in the category, such as eggs and bean sprouts, are less clear than the positions of the barcodes on the other products.

[0140] The predetermined condition may also be that reading barcodes attached to products belonging to a category, such as eggs and bean sprouts, is more difficult than reading barcodes attached to other products.

[0141] The predetermined condition may also be that the products in the category, such as vegetables and fresh fish, do not have barcodes attached to them. When registering products without barcodes, special operations such as registering using a touch panel are required, which makes it easy for products to be overlooked. The no-product category may also be a category input from outside.

[0142] In addition, the check device reading unit 330 of this embodiment reads associated information (e.g., a barcode) associated with the product. As shown in Figs. 7 and 8, the check device display control unit 315 further displays on the display screen for each category the name of the category and the number of products belonging to the category for which the associated information has been read.

[0143] In addition, the display number determination unit 312 of the present embodiment determines the display number. The display number determination unit 312 may determine the display number by regarding a plurality of categories as one category.

[0144] [Effect description] The display number determination unit 312 of the check system 10 of this embodiment determines the display number, which is the number of registered products, for each category based on the categories and product numbers included in the registration list. The check device display control unit 315 also displays the determined display numbers for each category on the check screen. The check device display control unit 315 also displays the display number as 0 for categories with no registered products on the check screen.

[0145] With the above configuration, employees using the check system 10 of this embodiment can refer to the display count for each category and can also identify categories with zero registered products, thereby more reliably checking for products that have not been registered by users.

[0146] Although the present embodiment has been described above, the above-described embodiment can be modified. For example, all or part of the functions of the POS terminal 100, the management server 200, and the checking device 300 may be provided in other devices or servers.

[0147] As a specific example, if the POS terminal 100 is a self-checkout device installed in the payment area of ​​a store, information about products registered in the POS terminal 100 may be stored in the memory of the POS terminal 100 without being transmitted to the management server 200.

[0148] That is, the POS terminal 100 may include the registration information storage unit 240. When the POS terminal 100 includes the registration information storage unit 240, the check device 300 acquires the registration list from the POS terminal 100.

[0149] Furthermore, the checking device 300 may generate a check history by storing the check results in a memory of the checking device 300, without transmitting the check results to the management server 200.

[0150] Furthermore, the check device 300 does not necessarily have to include the check device reading unit 330. If the check device 300 does not include the check device reading unit 330, the employee uses the POS terminal 100 to read the barcode of the product to be checked for unregistered items.

[0151] Next, the POS terminal 100 transmits information about the product whose barcode has been read to the check device 300. The check device 300 determines whether or not the product information received from the POS terminal 100 is included in the registration list.

[0152] The display number determination unit 312 may determine the display number using a machine learning model such as a convolutional neural network (CNN). When using a machine learning model, the display number determination unit 312 inputs, for example, a registration list, a check result, or user information into a trained model of the machine learning model. Next, the display number determination unit 312 obtains the display number, which is an output of the trained model.

[0153] Furthermore, when the number of products included in the registration list is small (for example, five or less), the determination and display of the display number may be omitted.

[0154] Even if the determination of the number to be displayed and the display are omitted, the check device display unit 350 of the check device 300 displays a check screen including the registration list display section a and the confirmation completion button c.

[0155] Next, an overview of the present invention will be described. Fig. 11 is a block diagram showing an overview of a display device according to the present invention. A display device 20 according to the present invention includes a display unit 21 (e.g., a check device display control unit 315) that displays, on a display screen, each display number, which is the number of products included in a product list determined for each category, based on a product list composed of a plurality of product information including products and the categories to which the products belong, and the display unit 21 displays, on the display screen, for each category, the name of the category together with the display number determined for that category, and further displays, on the display screen, the name of the no-product category together with a display number of 0 for at least one no-product category that is a category not included in the product list.

[0156] When a display device having such a configuration is used, employees can more reliably check for any products that have not been registered by the user.

[0157] The no-product category may be a category that satisfies a predetermined condition. The predetermined condition may be that the loss rate of products belonging to the category is higher than a predetermined standard.

[0158] When a display device with such a configuration is used, employees can more reliably check for missed registrations of products with high loss rates.

[0159] The predetermined condition may also be that the unit price of products belonging to a category is higher than a predetermined value.

[0160] When a display device having such a configuration is used, employees can more reliably check for missed registrations of relatively high-priced items.

[0161] The non-product category may also be an externally input category.

[0162] When such a display method is used, employees can flexibly change the way they check depending on the products being sold in the store.

[0163] In addition, the display device 20 may be equipped with a reading unit (e.g., a check device reading unit 330) that reads associated information associated with the product, and the display unit 21 may further display on the display screen for each category the name of the category and the number of products belonging to that category for which the associated information has been read.

[0164] When a display device having such a configuration is used, employees can more reliably check for any products that have not been registered by the user.

[0165] Furthermore, the display device 20 may include a determination unit that determines the number of items to be displayed (for example, the number-of-items determination unit 312). Furthermore, the determination unit may determine the number of items to be displayed by regarding a plurality of categories as one category.

[0166] When a display device having such a configuration is used, employees can flexibly change the checking method depending on the situation of the store. [Explanation of symbols]
