Summary of the Invention

Problems to be Solved by the Invention

[0004] However, even if a store clerk or a registration POS device designates a specific checkout POS device, there is a problem that if a customer checks out using a checkout POS device different from the checkout POS device designated by the store clerk or the like, there is a risk of incorrect checkout. For this reason, it is conceivable that the registration POS device discharges receipt information for checkout and the customer inputs this receipt information for checkout into the checkout POS device to prevent incorrect checkout. However, in this case, the customer needs to input the receipt for checkout into the checkout POS device each time they check out, and there is a problem that they cannot quickly check out using the checkout POS device.

[0005] Therefore, the present invention aims to provide a sales information management system, a control method for the sales information management system, and a control program for the sales information management system that can minimize the effort required from customers while preventing incorrect settlements with high accuracy.

[0006] The object of the present invention is a sales information management system comprising: a registration-side imaging device which is an imaging device for capturing the customer's biometric information and a registration sales information processing device for inputting purchase target information which the customer intends to purchase; a plurality of settlement-side imaging devices which are imaging devices for capturing the customer's biometric information and are configured to allow the customer to perform settlement processing on the purchase target information themselves; and a sales information management device arranged to communicate with these registration sales information processing devices and settlement sales information processing devices, wherein the registration sales information processing device comprises a registration-side customer information input unit for inputting the customer's member information and a printing device for printing purchase target identification information which identifies each of the customer's purchase target information; the settlement sales information processing device comprises a settlement-side customer information input unit for inputting the customer's member information and a purchase target identification information input unit for inputting the purchase target identification information; and the sales information management device comprises registration biometric information which is the biometric information captured by the registration-side imaging device and the biometric information captured by the settlement-side imaging device. This is achieved by a sales information management system comprising: a biometric information identity determination unit that determines the identity of biometric information at the time of settlement; a member identity determination unit that determines the identity of member information entered from the registration-side customer information input unit and member information entered from the settlement-side customer information input unit; and a purchase target identification identity determination unit that determines the identity of purchase target identification information entered from the purchase target identification information input unit and purchase target identification information printed by the printing device, wherein only when the biometric information identity determination unit cannot determine the identity of the biometric information, the settlement-side customer information input unit or the purchase target identification information input unit of the settlement sales information processing device requests input of member information or purchase target identification information, the member identity determination unit determines the identity of member information, or the purchase target identification identity determination unit determines the identity of purchase target identification information, and the sales information management device is configured to delete the stored biometric information when the settlement process of the settlement sales information processing device is completed.

[0007] According to the above configuration, the sales information management device is configured such that, only when the biometric information identity determination unit cannot determine the identity of biometric information, such as facial information, the member identity determination unit determines the identity of member information (e.g., member ID information, etc.), or the purchase target identification identity determination unit (e.g., settlement receipt identity determination unit, etc.) determines the identity of purchase target identification information (e.g., settlement receipt information, etc.). Therefore, once the identity of the customer is determined through facial information, etc., the "settlement process" can be executed immediately, minimizing the effort involved in the settlement process by eliminating the need for additional operations such as providing member ID information, and enabling the settlement process to be carried out quickly.

[0008] On the other hand, if the biometric information identity determination unit cannot determine the identity of biometric information (e.g., facial information), there is a possibility that the customer may perform an incorrect settlement process. In such cases only, the settlement sales information processing device (e.g., settlement POS device) will request input of member ID information or purchase item identification information (settlement receipt information, etc.). After this input, the member identity determination unit or settlement receipt identity determination unit will perform additional processing to prevent the customer from performing an incorrect transaction. Furthermore, according to the above configuration, the sales information management device is configured to delete stored biometric information (e.g., facial information) when the settlement process of a POS device or the like is completed. Therefore, the device does not retain any personal information such as customers' biometric data (e.g., facial information), thus protecting personal information.

[0009] Preferably, of the plurality of settlement sales information processing devices of the sales information management system, at least one settlement sales information processing device is positioned within the visible range of the operator of the registration sales information processing device, and the registration sales information processing device is a monitorable settlement sales information processing device capable of monitoring the execution status of the settlement processing of the settlement sales information processing device, and the sales information management device stores high-risk information regarding the purchase target information which has a high probability of fraud occurring, and has a high-risk determination unit that determines whether the customer's purchase target information falls under the high-risk information, and when the high-risk determination unit determines that the customer's purchase target information includes the high-risk information and determines that the member ID information which is the member information entered into the registration-side customer information unit is not already registered member ID information, the display unit of the registration sales information processing device displays the items to be settled by the monitorable settlement sales information processing device, and the purchase target information including the high-risk information is processed as being settleable only by the monitorable settlement sales information processing device.

[0010] According to the above configuration, when the high-risk determination unit determines that the customer's purchase target information (e.g., planned purchase items, etc.) includes high-risk information (e.g., high-risk product information, etc.), and determines that the member ID information entered in the registration-side customer information unit is not already registered member information, the display unit of the registration sales information processing device (e.g., registration POS device, etc.) will display that the planned purchase items, etc. should only be settled using the monitorable settlement sales information processing device (e.g., monitorable settlement POS device, etc.). This monitorable POS system is positioned within the visible range of the operator of the registered POS system, and the registered POS system is configured to monitor the execution status of the settlement process of the settlement sales information processing device (e.g., the settlement POS system). Therefore, if a customer's planned purchases include high-risk items such as high-priced goods or items that can be resold, requiring the customer to complete the payment process using a visible, monitorable POS system can prevent fraudulent activity such as customers taking items without paying.

[0011] Furthermore, since operators of registered POS devices (such as store employees) can monitor the monitorable POS devices, they can verify whether or not a customer is actually performing the payment process, thereby reliably preventing fraudulent activities. Furthermore, since the sales information management device has a high-risk judgment unit (for example, a high-risk product judgment unit), operators of registered POS devices can automatically identify products that are likely to lead to fraudulent activity, and can recognize the occurrence of fraudulent activity with greater accuracy.

[0012] Preferably, when settlement is initiated in the monitorable settlement sales information processing device of the sales information management system, a notification that settlement has been initiated is displayed on the registration sales information processing device.

[0013] According to the above configuration, when settlement is initiated at a monitorable settlement sales information processing device (e.g., a monitorable settlement POS device), a notification that settlement has been initiated is displayed on a registration sales information processing device (e.g., a registration POS device). Therefore, the operator of the registration POS device can understand that the purchase target (e.g., planned purchase items) containing high-risk information (e.g., high-risk product information) has not been settled if they do not receive a notification.

[0014] Preferably, the system is characterized by having a modification unit that, when all of the monitorable settlement sales information processing devices of the sales information management system are in use, changes the settlement sales information processing device adjacent to the monitorable settlement sales information processing device to the monitorable settlement sales information processing device.

[0015] According to the above configuration, when all monitorable settlement sales information processing devices (e.g., monitorable settlement POS devices, etc.) are in use, a change unit (e.g., settlement POS device change unit, etc.) is provided to change an adjacent settlement sales information processing device (e.g., settlement POS device, etc.) to a monitorable settlement POS device, thereby preventing situations such as insufficient installation of monitorable settlement sales information processing devices.

[0016] Preferably, the sales information management system according to claim 2 or 3, wherein identifiable identification information is displayed on the monitorable settlement sales information processing device of the sales information management system, and the registration sales information processing device is configured such that the printing device prints the identification information of the monitorable settlement sales information processing device that processes the purchase target information.

[0017] According to the above configuration, an identifiable identification information (e.g., an identification number) is displayed on the monitorable settlement sales information processing device (e.g., a monitorable settlement POS device), and the registration sales information processing device (e.g., a registration POS device) prints the identification information of the monitorable settlement POS device that processes the settlement of the purchase target information (e.g., planned purchase items) using a printing device (e.g., a printer). As a result, customers can easily identify the monitorable settlement POS device to which they should settle their accounts.

[0018] Preferably, the biometric information identity determination unit is configured to determine the identity of the biometric information only when the settlement process is started in the settlement sales information processing device within the normal travel time of the customer from the registration sales information processing device to the settlement sales information processing device, after the completion of the input process of the purchase target information in the sales information management system.

[0019] According to the above configuration, the biometric information identity determination unit (e.g., facial information identity determination unit) determines the identity of the customer's biometric information (facial information, etc.) only when the settlement process is started at the settlement POS device within the customer's normal travel time from the registration POS device to the settlement POS device (e.g., settlement POS device) after the completion of the input process for purchase target information (e.g., planned purchase items, etc.) at the registration sales information processing device (e.g., registration POS device, etc.) (e.g., 1 to 5 minutes, etc.). In this way, the facial information identity determination unit of the sales information management device can make the determination efficiently.

[0020] Preferably, when the high-risk determination unit of the sales information management system determines that the high-risk information is included in the purchase target information of a customer, caution information requesting input of the member information of the customer is displayed on the display unit of the registration sales information processing device, and the input member information is stored in association with the biometric information of the customer and is stored until the settlement process in the settlement sales information processing device ends, and after the end, the face information of the customer is deleted.

[0021] According to the above configuration, for a customer who purchases purchase target information (e.g., planned purchase items, etc.) including high-risk information (e.g., high-risk product information, etc.), the registration sales information processing device (e.g., registration POS device, etc.) requests input of member information (e.g., member ID information, etc.), and the input member ID information, etc. and the biometric information (e.g., face information, etc.) of the customer are stored in association with each other. Therefore, when the customer commits an illegal act or the like, the individual can be identified immediately. On the other hand, when the customer does not commit any illegal act and the settlement process is completed by the settlement sales information processing device (e.g., settlement POS device, etc.), the face information, etc. of the customer is deleted. Thereby, the personal information of the customer is also protected. ​​​​​​According to the above configuration, when member information (e.g., member ID information) is not entered, the function change unit (e.g., registration POS device change unit) operates, causing the registration sales information processing device (e.g., registration POS device) to function as a settlement sales information processing device (e.g., settlement POS device), thereby reliably preventing fraudulent activity by customers.

[0024] According to the present invention, the above object is achieved by a control method of a sales information management system having a registration-side imaging device that images a customer, a registration sales information processing device for inputting purchase target information that is the customer's purchase plan, an accounting-side imaging device that images the customer's biometric information, and a plurality of accounting sales information processing devices configured such that the customer can perform an accounting process on the purchase target information by himself / herself, and a sales information management device arranged to be communicable with the registration sales information processing device and the accounting sales information processing device. The registration sales information processing device includes a registration-side customer information input unit for inputting the customer's membership information and a printing device for printing purchase target identification information for identifying each of the customer's purchase target information. When the customer's membership information is input to the accounting-side customer information input unit of the accounting sales information processing device and the purchase target identification information is input to the purchase target identification information input unit, a biometric information identity determination unit of the sales information management device determines the identity between registration-time biometric information, which is the biometric information imaged by the registration-side imaging device, and accounting-time biometric information, which is the biometric information imaged by the accounting-side imaging device. A membership identity determination unit of the accounting sales information processing device determines the identity between the membership information input from the registration-side customer information input unit and the membership information input from the accounting-side customer information input unit. A purchase target identification identity determination unit of the sales information management device determines the identity between the purchase target identification information input to the purchase target identification information input unit and the purchase target identification information printed by the printing device. Only when the biometric information identity determination unit cannot determine the identity of the biometric information, the accounting-side customer information input unit or the purchase target identification information input unit of the accounting sales information processing device requests the input of the membership information or the purchase target identification information, the membership identity determination unit determines the identity of the membership information, or the purchase target identification identity determination unit determines the identity of the purchase target identification information. The sales information management device is configured to delete the stored biometric information when the accounting process of the accounting sales information processing device ends.

[0025] The objective is that, according to the present invention, a sales information processing device for registration has a registration-side imaging device which is an imaging device for imaging a customer and for inputting purchase target information which is the customer's intended purchase; a plurality of settlement-side imaging devices which are imaging devices for imaging the customer's biometric information and are configured to allow the customer to perform settlement processing on the purchase target information themselves; a sales information management device arranged to communicate with these registration-side sales information processing devices and settlement-side sales information processing devices; and the registration-side sales information processing device has a registration-side customer information input unit for inputting the customer's membership information and a printing device for printing purchase target identification information which identifies each of the customer's purchase target information, wherein the settlement-side customer information input unit of the settlement-side sales information processing device has a function in which the customer's membership information is input and the purchase target identification information is input to the purchase target identification information input unit, and the biometric information identity determination unit of the sales information management device determines the biometric information at registration which is the biometric information imaged by the registration-side imaging device and the biometric information at settlement which is the biometric information imaged by the settlement-side imaging device. This is achieved by a control program for a sales information management system that enables the following functions: a function to determine the identity of biometric information; a function in which the member identity determination unit of the settlement sales information processing device determines the identity of the member information entered from the registration-side customer information input unit and the member information entered from the settlement-side customer information input unit; a function in which the purchase target identification identity determination unit of the sales information management device determines the identity of the purchase target identification information entered from the purchase target identification information input unit and the purchase target identification information printed by the printing device; a function in which, only if the biometric information identity determination unit cannot determine the identity of the biometric information, the settlement-side customer information input unit or the purchase target identification information input unit of the settlement sales information processing device requests input of the member information or the purchase target identification information; a function in which the member identity determination unit determines the identity of the member information, or the purchase target identification identity determination unit determines the identity of the purchase target identification information; and a function in which the sales information management device deletes the stored biometric information when the settlement process of the settlement sales information processing device is completed. [Effects of the Invention]

[0026] As described above, the present invention has the advantage of providing a sales information management system, a control method for the sales information management system, and a control program for the sales information management system that can prevent incorrect settlements and the like with accuracy while minimizing the effort required from customers.

[Modes for carrying out the invention]

[0028] Hereinafter, preferred embodiments of this invention will be described in detail with reference to the accompanying drawings and other materials. The embodiments described below are preferred examples of the present invention and are subject to various technically preferred limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise stated in the following description.

[0029] (Main components of POS management system 1) Figure 1 is a schematic diagram showing the main configuration of "POS Management System 1" according to an embodiment of the sales information management system of the present invention. Here, POS stands for "Point of Sale," and refers to a system that records and aggregates sales data for individual items at the time of sale in stores, etc.

[0030] As shown in Figure 1, the system 1 includes, for example, a "registration POS device 100a," which is a sales information processing device for registration that is placed in a store Z or the like. In this embodiment, multiple registration POS devices 100a are installed in store Z, but Figure 1 shows only one of them, and the other registration POS devices have a similar configuration. This registration POS device 100a is a device for inputting purchase information, such as planned purchase items, that a customer C etc. intends to purchase at store Z, and is input by, for example, a store employee S at store Z.

[0031] Furthermore, System 1 includes, for example, POS devices 200a, 200b, etc., which are sales information processing devices for settlement that are placed in store Z. In this embodiment, store Z has two or more POS payment devices 200a, 200b, etc., but Figure 1 shows only two of them, POS payment devices 200a and 200b, and the other POS payment devices have a similar configuration. This POS system 200a, etc., is configured so that customers C can perform the payment process themselves for the items they intend to purchase at store Z.

[0032] In other words, in this embodiment, the system 1 is a so-called "semi-self-service system" in which the customer C first inputs and registers the items to be purchased using the registration POS device 100a operated by the store clerk S, and then moves to the payment POS device 200a and performs the payment process themselves.

[0033] Furthermore, in Figure 1, store Z includes a monitorable payment POS device 300a, which is a sales information processing device for monitoring payments. This monitorable POS system 300a has a configuration similar to that of the POS system 200a, etc., but is positioned within the visible range of the store clerk S who operates the registered POS system 100a, etc., and the execution status of its settlement process can be monitored by the registered POS system 100a. The functions of this monitorable POS system 300a will be described later.

[0034] Furthermore, as shown in Figure 1, System 1 includes, for example, a management server 10, which is a sales information management device. As shown in Figure 1, this management server 10 is configured to communicate with the registered POS device 100a, settlement POS device 200a, etc., and the monitorable settlement POS device 300a located in store Z via the internet network 2, etc., and manages sales information, etc., of store Z.

[0035] The management server 10, registration POS device 100a, settlement POS device 200a, etc., and the monitorable settlement POS device 300a, etc., shown in Figure 1, are all computers equipped with a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), hard disk, etc., and are connected via a bus.

[0036] Figure 2 is a schematic block diagram showing the main components of the registered POS device 100a shown in Figure 1. As shown in Figure 2, the registration POS device 100a has a "registration POS side control unit 101," which controls a "registration POS side communication device 102" for communicating with the management server 10 etc. in Figure 1, and a registration side imaging device, such as a "registration POS side camera 103," which captures biometric information of customer C, such as facial information.

[0037] Furthermore, as shown in Figure 2, the control unit 101 controls a display unit that displays various information, such as the "Registered POS Side Display 104," a registered customer information input unit that inputs customer C's membership information, such as member ID information, such as the "Registered POS Side Information Input Unit 105," a printing device that prints purchase target identification information that identifies the products that customer C plans to purchase, such as "Settlement Receipt Information," such as the "Printer 106," and a "Registered POS Side Various Information Storage Unit 107" that stores various information.

[0038] Figure 3 is a schematic block diagram showing the main components of the POS payment devices 200a and 200b, the monitorable POS payment device 300a, etc., as shown in Figure 1. Since the settlement POS device 200a and the monitorable settlement POS device 300a have similar configurations, the settlement POS device 200a will be used as an example for the following explanation. As shown in Figure 3, the POS payment device 200a has a "POS payment side control unit 201," which controls a "POS payment side communication device 202" for communicating with the management server 10 etc. in Figure 1, and a "POS payment side camera 203," which is a POS payment side imaging device that captures biometric information of customer C, such as facial information.

[0039] Furthermore, as shown in Figure 3, the control unit 201 controls the "POS-side display 204" which displays various information, the "POS-side information input unit 205" which is a customer information input unit for customer C that inputs member ID information, etc., and the "receipt input unit 206" which is a purchase target identification information input unit that inputs receipt information for settlement. Furthermore, the control unit 201 also controls the "settlement POS side various information storage unit 207" which stores various types of information.

[0040] Figure 4 is a schematic block diagram showing the main configuration of the management server 10 in Figure 1. As shown in Figure 4, the system has a server-side control unit 11, which controls a "server-side communication device 12" for communicating with the registration POS device 100a and settlement POS device 200a shown in Figure 1.

[0041] Furthermore, as shown in Figure 4, the control unit 11 also controls the "customer face-related information storage unit 15," "high-risk product determination unit (program) 16," "high-risk product information storage unit 17," "member ID information storage unit 18," "monitoringable POS device presence / absence determination unit (program) 19," "POS device change unit (program) 20," "travel time processing unit (program) 21," "face identity determination unit (program) 22," "member identity determination unit (program) 23," and "checkout receipt identity determination unit (program) 24," etc., but the details of these will be described later.

[0042] Figures 5 to 9 are schematic flowcharts illustrating the main operation examples of System 1. In this embodiment, the following explanation will be given using an example where customer C purchases a product at store Z. (Preliminary process) First, if customer C has their own member ID information, they store their member ID information, for example, "123456", etc., in the "member ID information storage unit 18" of the management server 10 beforehand. This completes the preliminary steps.

[0043] (Example of operation of this system 1) First, in step 1 of Figure 5 (hereinafter referred to as "ST"), customer C brings the items they intend to purchase, such as vegetables, meat, or high-quality whiskey. Store employee S at store Z inputs and registers customer C's planned purchase items using the registration POS device 100a that S manages.

[0044] Next, the process proceeds to ST2. In ST2, the registration POS-side camera 103 of the registration POS device 100a captures the facial information of customer C standing in front of the registration POS device 100a, and transmits the captured facial information (facial image) to the management server 10 as "Registration-time facial information (facial image) (an example of registration-time biometric information)." The management server 10 stores customer C's "registered face image" in the "customer face-related information storage unit 15" shown in Figure 4.

[0045] In this invention, "biological information" may not only refer to facial images, but also to physical characteristics such as hand length, foot length, or clothing characteristics such as hat color, clothing color, etc.

[0046] Next, in ST3, when employee S enters information about the items to be purchased (vegetables, meat, premium whiskey, etc.) into the registered POS device 100a, the registered POS device 100a sends the information about the items to be purchased to the management server 10. The management server 10 stores the "information on products to be purchased" associated with customer C's "customer face image" in the "customer face-related information storage unit 15" shown in Figure 4.

[0047] Figures 10 and 11 are schematic diagrams illustrating the progression of "customer face-related information" stored in the customer face-related information storage unit 15. Figure 10(1) shows customer face-related information (part 1) in ST3, which stores customer C's registered face information and the products they intend to purchase in association with each other.

[0048] Next, the process proceeds to ST4. In ST4, the "High-Risk Product Judgment Unit (an example of a high-risk judgment unit) 16" of the management server 10 (Figure 4) operates and refers to the information in the "High-Risk Product Information Storage Unit 17" (Figure 4). Here, the "high-risk product information (an example of high-risk information)" stored in the "high-risk product information storage unit 17" refers to products sold at store Z that have a particularly high probability of fraud occurring, such as high-priced products or products that can be resold, and these products are stored as "high-risk products."

[0049] The "high-risk product determination unit 16" then determines whether or not the products that customer C intends to purchase (vegetables, meat, premium whiskey, etc.) include "high-risk products."

[0050] Furthermore, in this embodiment, the high-risk product determination unit may not only determine whether each of customer C's planned purchase items is a "high-risk product," but also whether the total amount of customer C's planned purchase items is above a predetermined amount. In this case, if the total amount is above the predetermined amount, the product will be determined to be a "high-risk product."

[0051] If high-risk products are included in ST5, the process proceeds to ST6. In ST6, the registered POS-side display 104 of the registered POS device 100a displays "Payment should be made at the monitorable settlement POS device 300a," along with "warning information" requesting customer C to enter their "member ID information."

[0052] Here, the "monitored settlement POS device 300a" ​​is a settlement POS device 200a etc. that is positioned within the visible range of the store clerk S (operator) of the registered POS device 100a, and that the registered POS device 100a can monitor the execution status of settlement processing of the settlement POS device 200a etc.

[0053] Next, proceed to ST7. In ST7, the management server 10 stores in the customer's "customer face-related information storage unit 15" that the payment processing for customer C's products is "only for the monitorable payment POS device 300a".

[0054] The customer face-related information (part 2) in the "customer face-related information storage unit 15" of ST7 is as shown in Figure 10 (2). As shown in Figure 10(2), customer face-related information (part 3) stores customer C's registered face information and planned purchase information, along with information from the "monitoring POS only".

[0055] Next, the registration POS device 100a requests customer C's member ID information. Once the member ID information is entered in ST8, the process proceeds to ST9. In ST9, when member ID information (123456) is entered into the registration POS side information input unit 105 of the registration POS device 100a, the registration POS device 100a sends the member ID information to the management server.

[0056] Next, the process proceeds to ST10. In ST10, the management server 10 determines whether the member ID information is already registered and stored in the "member ID information storage unit 18". If it is already registered, the member ID information is stored in the customer face-related information storage unit 15, associated with the information of products to be purchased, etc. Figure 10(3) is a schematic diagram illustrating the "customer face-related information (part 3)" in the customer face-related information storage unit 15 of ST10. As shown in Figure 10(3), when customer C registers, their facial information and information on products they plan to purchase are stored together with their "member ID information (for example, 123456)". Thus, in this embodiment, if customer C has already registered their member ID information, they are not required to process the payment using the monitorable POS device 300a as described later, but rather the payment is processed using a regular POS device 200a or the like. This is because customer C has already been identified on management server 10, making it extremely unlikely that any fraudulent activity will occur.

[0057] On the other hand, if the member ID information is not entered in ST8, the process proceeds to ST11. In ST11, the printer 106 of the registered POS device 100a prints and outputs "settlement receipt information" to customer C, which identifies the information of the items that customer C intended to purchase. Furthermore, the registered POS device 100a transmits the "settlement receipt information" to the management server 10.

[0058] Next, the process proceeds to ST12. In ST12, the management server 10 stores the "settlement receipt information" in the customer face-related information storage unit 15, associating it with information such as the products to be purchased.

[0059] Figure 10(4) is a schematic diagram illustrating the "customer face-related information (part 4)" in the customer face-related information storage unit 15 of ST12. As shown in Figure 10(4), customer C's facial information at the time of registration, information on products to be purchased, information only from the monitoring POS, and member ID information are stored together with "receipt information for settlement".

[0060] After ST12, proceed to ST13. In ST13, the "Monitored Payment POS Device Availability Determination Unit 19" in Figure 4 of the management server 10 operates to determine whether there is a "Monitored Payment POS Device 300a" ​​that is currently unused and should be used for payment by customer C.

[0061] If, in ST14, there is currently an unused "monitored payment POS device 300a" ​​that customer C should settle, proceed to ST15. In ST15, if there is an unused monitorable settlement POS device 300a, the management server 10 displays on the registered POS-side display 104 that an unused monitorable settlement POS device 300a exists, specifically the identification number 110 of the monitorable settlement POS device 300a (for example, an example of identification information).

[0062] Then, the store clerk S, who operates the registered POS device 100a, etc., informs customer C of the identification number 110, etc., of one or more unused monitorable settlement POS devices 300a, etc. In this way, by being notified by the store clerk S, customer C can reliably and easily select the monitorable POS device 300a to which they should make a payment, either from the said monitorable POS device 300a in the case of a single customer, or from multiple monitorable POS devices 300a in the case of multiple customers.

[0063] Furthermore, the present invention is not limited to this, and when there are multiple usable monitorable settlement POS devices 300a, etc., the monitorable settlement POS devices 300a, etc. may be ranked in order of ease of monitoring, and the registered POS device 100a may designate the monitorable settlement POS devices 300a, etc. in order of ease of monitoring.

[0064] On the other hand, if no unused monitorable POS devices 300a, etc. exist in ST14, proceed to ST16. In ST16, the "Settlement POS Device Change Unit (Example of Change Unit) 20" in Figure 4 of the management server 10 operates, temporarily changing the settlement POS device 200a, etc., located closest to the registered POS device 100a to a monitorable settlement POS device 300a, and sending its identification number (for example, 103) to the registered POS device 100a.

[0065] Next, proceed to ST17. In ST17, the registered POS device 100a displays the identification number on the registered POS-side display 104 and / or on the settlement receipt that prints the settlement receipt information. Therefore, customer C can always complete the payment process using the monitorable POS device 300a, preventing situations where customers have to wait to pay due to insufficient installation.

[0066] As described above, in this embodiment, when the high-risk product determination unit 16 determines that the product that customer C intends to purchase includes high-risk product information, a message indicating that payment should be made at the "monitored settlement POS device 300a" ​​is displayed on the registration POS-side display 104 of the registration POS device 100a. This monitorable POS system 300a is positioned within the visible range of the store clerk S, who is the operator of the registered POS system 100a, and the registered POS system 100a is configured to monitor the execution status of its settlement process.

[0067] Therefore, if customer C's planned purchases include high-risk items such as high-priced goods or items that can be resold, store Z employees such as S can prevent fraudulent activity such as customer C taking the purchased items without paying by forcing customer C to process the payment using a monitorable POS system where the payment process can be visually observed. In other words, since the store clerk S, who is the operator of the registered POS device 100a, can monitor the monitorable settlement POS device 300a, he can confirm whether or not customer C is actually performing the settlement process, and thus reliably prevent fraudulent activities from occurring. Furthermore, since the management server 10 has a high-risk product determination unit 16, the operator (store clerk S) of the registered POS device 100a can automatically identify products that are likely to lead to fraudulent activities, and can recognize the occurrence of fraudulent activities with greater accuracy.

[0068] On the other hand, if ST5 determines that no high-risk products are included, the registered POS device 100a requests customer C to enter their member ID information. Then, if the member ID information is entered in ST18, proceed to ST19. In ST19, when member ID information (for example, 123456) is entered into the registration POS side information input unit 105 of the registration POS device 100a, the registration POS device 100a transmits the member ID information to the management server 10.

[0069] Next, the process proceeds to ST20. In ST20, the management server 10 determines whether the member ID information is already registered and stored in the "member ID information storage unit 18". If it is already registered, the member ID information is stored in the "customer face-related information storage unit 15" in association with the information of the products to be purchased, etc.

[0070] Figure 11(1) is a schematic diagram illustrating the "customer face-related information (part 5)" in the customer face-related information storage unit 15 of ST20. As shown in Figure 11(1), the "Member ID information" is stored in association with the customer C's facial information and planned purchase information at the time of registration.

[0071] On the other hand, if the member ID information is not entered in ST18, proceed to ST21. In ST21, the printer 106 of the registered POS device 100a prints (distributes) "settlement receipt information" that identifies the items that customer C intends to purchase to customer C. Furthermore, the registered POS device 100a transmits the settlement receipt information to the management server 10.

[0072] Next, the process proceeds to ST22. In ST22, the management server 10 stores the settlement receipt information in the customer face-related information storage unit 15, associating it with information such as the products to be purchased.

[0073] Figure 11(2) is a schematic diagram illustrating the "customer face-related information (part 6)" in the customer face-related information storage unit 15 of ST22. As shown in Figure 11(2), customer C's facial information and planned purchase information are stored together with "payment receipt information" at the time of registration.

[0074] After ST10, ST15, ST17, ST20, and ST22, the process proceeds to ST23 in Figure 7. In ST23, the employee S of the registered POS device 100a instructs customer C to make a payment at the monitorable payment POS device 300a or payment POS device 200a, etc., and customer C goes to the monitorable payment POS device 300a or payment POS device 200a, etc.

[0075] Next, the process proceeds to ST24. In ST24, the POS-side camera 203 of the monitorable POS device 300a or POS device 200a captures a facial image of customer C and transmits it to the management server 10 as a "facial image at checkout (an example of biometric information at checkout)" along with the time information of the image capture. The management server 10 stores the "face image at the time of settlement" in the customer face-related information storage unit 15.

[0076] Figure 11(3) is a schematic diagram illustrating the "customer face-related information (part 7)" in the customer face-related information storage unit 15 of ST24. As shown in Figure 11(3), "face information at checkout" is stored in association with customer C's registration information, planned purchase information, member ID information, or payment receipt information.

[0077] Next, the process proceeds to ST25. In ST25, the "travel time processing unit 21" shown in Figure 4 of the management server 10 operates and determines whether the time when customer C's "settlement face image" was acquired is, for example, within 1 minute from the time when customer C completed the registration process at the registration POS device 100a.

[0078] In other words, it is determined whether customer C moved from the registration POS device 100a to the payment POS device 200a, etc., within the normal travel time (e.g., 1 minute), and whether a "face image at the time of payment" was captured. Then, in ST26, if it is determined that the travel time is not within the normal time frame, the user will be excluded from the "face identity determination" described later (ST28), and the user will proceed to ST31, described below, where they will be asked to enter their member ID information.

[0079] In this embodiment, by adopting this configuration, unnecessary processing in System 1 can be eliminated, making efficient processing possible. In other words, by limiting the scope of the identity determination, the accuracy of the determination can be improved, and processing can be expedited.

[0080] On the other hand, if it is determined in ST26 that the image was captured within the normal travel time, the process proceeds to ST27. In ST27, the "Face Identity Determination Unit (an example of a biometric information identity determination unit) 22" shown in Figure 4 of the management server 10 operates to determine whether the "Face Information at Settlement" is identical to the "Face Information at Registration," or whether it is difficult to determine the identity.

[0081] In this embodiment, identity is primarily determined by facial information, but the present invention is not limited to this, and may be configured to comprehensively determine identity by also including information such as the proportions of the face, clothing, and limbs. In this case, identity can be determined more reliably than with facial information alone. Furthermore, in this case, since there is no need to make detailed judgments about facial information, the accuracy of identity determination can be improved.

[0082] On the other hand, if it is determined in ST26 that the image was not captured within the normal travel time, the process proceeds to ST28, and no determination is made as to whether the facial information at the time of payment is identical to the facial information at the time of registration.

[0083] If ST29 determines that the facial information at the time of payment is identical to the facial information at the time of registration, the process proceeds to ST30. In ST30, the management server 10 transmits the "planned purchase information" associated with the "registered face image" etc. in the customer face-related information storage unit 15, which has been determined to be "identical," to the settlement POS device 200a or the monitorable settlement POS device 300a, and the settlement POS device 200a or the monitorable settlement POS device 300a performs settlement processing.

[0084] Therefore, customer C can complete the payment process for their purchases simply by standing in front of the POS terminal 200a or the monitorable POS terminal 300a, allowing customer C to complete the payment quickly with minimal effort.

[0085] Furthermore, in this embodiment, when the payment process is started in the monitorable POS device 300a, a notification to that effect is sent to the registered POS device 100a. Therefore, store clerk S, who is the operator of the registered POS device 100a, can accurately determine whether the settlement of goods including high-risk items has started or remains unsettled.

[0086] On the other hand, if ST29 determines that the facial information at the time of payment is not identical to the facial information at the time of registration, or that it is difficult to determine their identity, customer C will be asked to enter their member ID information at the payment POS device 200a or the monitorable payment POS device 300a.

[0087] In ST31, if member ID information is entered, that is, if customer C who has member ID information enters the member ID information into the settlement POS device 200a or the settlement POS side information input unit 205 of the monitorable settlement POS device 300a. Then, the settlement POS device 200a or the monitorable settlement POS device 300a transmits the entered member ID information to the management server 10.

[0088] Next, the process proceeds to ST33. In ST33, the management server 10's "member identity determination unit 23" operates, refers to the customer face-related information storage unit 15, determines the identity of the member ID information, and if they are identical, transmits the customer C's planned purchase information to the checkout POS device 200a or the monitorable checkout POS device 300a.

[0089] On the other hand, if no member ID information is entered in ST31, the process proceeds to ST34. In ST34, the settlement receipt information is entered into the settlement POS device 200a or the monitorable settlement POS device 300a. This information is then transmitted to the management server 10.

[0090] Next, the process proceeds to ST35. In ST35, the "Settlement Receipt Identity Determination Unit (an example of a Purchase Item Identification Identity Determination Unit) 24" of the management server 10 (shown in Figure 4) operates, refers to the customer face-related information storage unit 15 of customer C, determines the identity of the "Settlement Receipt Information," and if it is identical, transmits the customer C's planned purchase information to the settlement POS device 200a or the monitorable settlement POS device 300a.

[0091] After ST33 and ST35, the process proceeds to ST36. In ST36, the settlement POS device 200a or the monitorable settlement POS device 300a performs settlement processing based on the customer C's planned purchase information. Thus, according to this embodiment, even when the "face identity determination unit 22" does not determine that there is identity, customer C can reliably complete the payment process using member ID information or payment receipt information.

[0092] After ST28, ST30, and STT36, the process proceeds to ST37. In ST37, once the settlement process is complete, the management server 10 deletes the customer face-related information storage unit 15 if it contains the face image at the time of registration and the face image at the time of settlement. Therefore, in this embodiment, the personal information of customer C can be effectively protected.

[0093] On the other hand, if customer C engages in fraudulent activity before the settlement process is completed, the facial image used during registration and the facial image used during settlement will not be deleted immediately. Therefore, in this embodiment, it becomes possible to identify individuals from these facial images and member IDs, etc., enabling prompt compensation for damages at store Z, etc.

[0094] (First modified example of this embodiment) The following describes a first modification of this embodiment. Since many of the components of the first modification are the same as those of the embodiment described above, the following description will mainly focus on the differences. In the first modified example, unlike this embodiment, the registered POS device 100a has a "registered POS function change unit (an example of a function change unit)" that allows it to function as a settlement POS device 200a, etc.

[0095] In this case, when customer C's planned purchase items include high-risk product information and member ID information is not entered, the "Registered POS Function Change Unit" is activated, causing the Registered POS device 100a to function as a settlement POS device 200a, etc., and the settlement process is also executed on the Registered POS device 100a where customer C registered their planned purchase items.

[0096] With this configuration, customer C performs the payment process in front of store clerk S at the registered POS device 100a where the items to be purchased are registered, thus reliably preventing fraudulent activity by the customer. In this case, the registered POS device 100a may print and dispense payment receipt information, and customer C, upon receiving it, may input the payment receipt information into the registered POS device 100a to complete the payment process. In this case, since customer C is solely responsible for the payment process, the burden on employee S is not increased, and the transaction can be processed efficiently.

[0097] (Second modified example of this embodiment) The following describes a second modification of this embodiment. Since many of the components of the second modification are the same as those of the embodiment described above, the following description will mainly focus on the differences. In the first modified example, unlike this embodiment, items that are even more expensive than the high-risk item information in this embodiment (for example, items costing 100,000 yen or more) are stored as "valuable items."

[0098] Furthermore, if this "valuable item" is included in the customer's planned purchases, as in the first modified example, the "registered POS function change unit" of the registered POS device 100a operates, causing the registered POS device 100a to function as a settlement POS device 200a, etc., and the settlement process is also executed on the registered POS device 100a where customer C registered the items they planned to purchase. Therefore, this modified version can effectively protect extremely valuable and rare goods from fraud.

[0099] (Third modified example of this embodiment) The following describes a third modified example of this embodiment. Since many of the components of the third modified example are the same as those of the embodiment described above, the following description will mainly focus on the differences. In the third modified example, unlike this embodiment, if all the settlement POS devices 200a, etc. are in use and there are no settlement POS devices 200a, etc. available for immediate use by customer C, then, as in the first modified example, the "registered POS function change unit" of the registered POS device 100a operates, causing the registered POS device 100a to function as a settlement POS device 200a, etc., and the settlement process is also executed on the registered POS device 100a where customer C has registered the items they intend to purchase. This configuration allows customer C to process payments quickly in this modified example.

[0100] In the embodiments described above, the example given was that the invention is implemented as a device. However, the present invention is not limited thereto, and the invention may be stored and distributed as a program that can be executed by a computer on a storage medium such as a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a magneto-optical disk (MO), or a semiconductor memory.

[0101] Furthermore, the storage medium only needs to be capable of storing programs and be readable by a computer. The storage format of the storage medium is not particularly limited.

[0102] Furthermore, an operating system (OS) running on a computer, or middleware (MW) such as database management software or network software, may execute some of the processes necessary to realize this embodiment based on instructions from a program installed on the computer from a storage medium.

[0103] Furthermore, the storage medium in this invention is not limited to a medium independent of the computer, but also includes a storage medium that stores or temporarily stores programs that have been downloaded via a LAN, the Internet, or the like.

[0104] Furthermore, the computer in this invention only needs to execute each process in this embodiment based on a program stored in a storage medium, and may be a device consisting of a single personal computer or the like, or a system in which multiple devices are connected via a network.

[0105] Furthermore, the term "computer" in this invention is not limited to personal computers, but also includes arithmetic processing units, microcontrollers, and the like included in information processing equipment, and refers collectively to any equipment or device capable of realizing the functions of this invention through a program.

[0106] Embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or combined in any way different from those described above. [Explanation of symbols]
