Description

[Technical Field]

[0001] The present invention relates to a sales information management system that is installed in a store or the like and manages sales information such as sales, a control method for the sales information management system, and a control program for the sales information management system. [Background technology]

[0002] Conventionally, so-called semi-self-service POS (Point of Sale) devices have been introduced in stores to compensate for the shortage of store employees and to prevent customers from having to wait long times when paying. This semi-self-service POS device is a registration POS device managed by a store clerk, where the customer has the store clerk register the products they intend to purchase, and then the payment for the registered products is made at a settlement POS device operated by the customer themselves (for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] No. 5783149 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if a store clerk or a registered POS device designates a specific settlement POS device, there is a risk of incorrect settlement if the customer pays at a settlement POS device other than the one designated by the store clerk. For this reason, it is possible to prevent erroneous payments by having the registered POS device emit payment receipt information and having the customer enter this payment receipt information into the payment POS device, but this would require the customer to enter the payment receipt into the payment POS device each time they make a payment, which creates the problem of not being able to quickly settle the payment at the payment 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 prevent incorrect payments and other errors with high accuracy while minimizing the hassle for customers.

[0006] According to the present invention, the object is to provide a sales information management system comprising: a registration sales information processing device having a registration-side imaging device which is an imaging device that captures biometric information of a customer and for inputting purchase object information that the customer plans to purchase; a plurality of settlement sales information processing devices having a settlement-side imaging device which is the imaging device that captures the biometric information of the customer and configured to allow customers to perform settlement processing for the purchase object information themselves; and a sales information management device arranged to be able to communicate with the registration sales information processing devices and the settlement sales information processing devices, wherein the registration sales information processing device comprises a registration-side customer information input unit for inputting customer membership information and a printing device for printing purchase object identification information that identifies each of the customer's purchase object information, and the settlement sales information processing device comprises a settlement-side customer information input unit for inputting the customer's membership information and a purchase object identification information input unit for inputting the purchase object identification information, and the sales information management device comprises registration-time 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. and a purchase object identification identity determination unit that determines the identity of the purchase object identification information input to the purchase object identification information input unit and the purchase object 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 purchase object identification information input to the purchase object identification information input unit or the purchase object identification information input unit of the sales information processing device for settlement requests the input of the member information or the purchase object identification information, and the member identity determination unit determines the identity of the member information, or the purchase object identification identity determination unit determines the identity of the purchase object identification information, and the sales information management device is configured to delete the stored biometric information when the settlement process of the sales information processing device for settlement is completed.

[0007] According to the above configuration, the sales information management device is configured so that only when the biometric information identity determination unit is unable to determine the identity of biometric information, for example, facial information, the member identity determination unit determines the identity of member information (e.g., member ID information, etc.), or the purchase object identification identity determination unit (e.g., settlement receipt identity determination unit, etc.) determines the identity of purchase object identification information (e.g., settlement receipt information, etc.). Therefore, once the identity of the facial information, etc. is determined, the customer can immediately carry out the "settlement process," and is not required to perform additional operations such as providing member ID information, etc., minimizing the effort required for the settlement process and allowing 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 the biometric information (e.g., facial information), there is a possibility that the customer will make an erroneous settlement process, etc. Therefore, only in such cases will the settlement sales information processing device (e.g., settlement POS device, etc.) request the input of member ID information, etc. or purchase item identification information (settlement receipt information, etc.), and after this input, the member identity determination unit or settlement receipt identity determination unit, etc. will perform additional processing, thereby preventing the customer from making an erroneous transaction. Furthermore, according to the above configuration, the sales information management device is configured to delete the stored biometric information (for example, face information) when the settlement process of the settlement POS device or the like is completed. Therefore, the personal information of the customer such as biometric information (for example, face information) is not left in the device, and the personal information can be protected.

[0009] Preferably, of the multiple sales information processing devices for settlement of the sales information management system, at least one of the sales information processing devices for settlement is positioned within the visible range of the operator of the sales information processing device for registration, and the sales information processing device for registration is a monitorable sales information processing device for settlement that can monitor the execution status of the settlement process of the sales information processing device for settlement, and the sales information management device stores high-risk information regarding the purchase object information that has a high probability of fraud occurring, and has a high-risk judgment unit that judges whether the purchase object information of a customer corresponds to the high-risk information, and when the high-risk judgment unit judges that the purchase object information of the customer includes the high-risk information and determines that the member ID information that is the member information input to the registration customer information unit is not already registered member ID information, the items that should be settled by the monitorable sales information processing device for settlement are displayed on the display unit of the sales information processing device for registration, and the purchase object information that includes the high-risk information is processed as being capable of settlement only by the monitorable sales information processing device for settlement.

[0010] According to the above configuration, when the high risk judgment unit determines that the customer's purchase information (e.g., the product to be purchased, etc.) contains high risk information (e.g., high risk product information, etc.) and determines that the member ID information entered into the registration customer information unit is not already registered member information, the display unit of the registration sales information processing device (e.g., the registration POS device, etc.) displays a message indicating that the product to be purchased, etc. should only be settled at a monitorable settlement sales information processing device (e.g., a monitorable settlement POS device, etc.). This monitorable settlement POS device, etc. is placed within the visible range of the operator of the registered POS device, etc., and is configured so that the registered POS device can monitor the execution status of the settlement process of the settlement sales information processing device (e.g., the settlement POS device, etc.). Therefore, if the items a customer plans to purchase include high-risk product information such as high-priced items or items that can be resold, an operator such as a store clerk can force the customer to complete the payment process using a visible, monitorable payment POS device, thereby preventing fraudulent acts such as taking away the items they plan to purchase without paying.

[0011] In addition, since the operator of the registered POS device (such as a store clerk) can monitor the monitorable settlement POS device, he or she can confirm whether the customer is actually performing the settlement process, thereby reliably preventing the occurrence of fraudulent activities, etc. Furthermore, since the sales information management device has a high-risk judgment unit (e.g., a high-risk product judgment unit, etc.), the operator of a registered POS device, etc. can automatically identify products, etc. that are likely to be purchased and lead to fraudulent activities, etc., and can more accurately recognize the occurrence of fraudulent activities, etc.

[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 begins on a monitorable settlement sales information processing device (e.g., a monitorable settlement POS device, etc.), a notification that settlement has begun is displayed on a registered sales information processing device (e.g., a registered POS device, etc.). Therefore, the operator of the registered POS device, etc., can understand that a purchase item (e.g., a product to be purchased, etc.) containing high-risk information (e.g., high-risk product information, etc.) has not been settled because the notification has not been received.

[0014] Preferably, the sales information management system is characterized in that, when all of the monitorable settlement sales information processing devices of the sales information management system are in use, a change unit is provided that 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 of the monitorable settlement sales information processing devices (e.g., monitorable settlement POS devices, etc.) are in use, a change unit (e.g., a settlement POS device change unit, etc.) is provided for the monitorable settlement POS device to change the adjacent settlement sales information processing device (e.g., a settlement POS device, etc.) to a monitorable settlement POS device, thereby preventing a shortage of monitorable settlement sales information processing devices, etc.

[0016] Preferably, the sales information management system described in claim 2 or claim 3 is characterized in that 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 so that the printing device prints the identification information of the monitorable settlement sales information processing device that processes the settlement of the purchase target information.

[0017] According to the above configuration, identifiable identification information (e.g., an identification number, etc.) is displayed on the monitorable settlement sales information processing device (e.g., a monitorable settlement POS device, etc.), and the registration sales information processing device (e.g., a registration POS device, etc.) is configured to print out the identification information of the monitorable settlement POS device, etc. that will process the settlement of the purchase information (e.g., a product to be purchased, etc.), using a printing device (e.g., a printer, etc.), so that customers, etc. can easily identify the monitorable settlement POS device, etc. with which they should make their settlement.

[0018] Preferably, the biometric information identity determination unit is configured to determine the identity of the biometric information only when, after the input process of the purchase object information in the registration sales information processing device of the sales information management system is completed, 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.

[0019] According to the above configuration, after the input process of purchase target information (e.g., product to be purchased, etc.) in the registration sales information processing device (e.g., registration POS device, etc.) is completed, the biometric information identity determination unit (e.g., facial information identity determination unit, etc.) determines the identity of the customer's biometric information (facial information, etc.) only when the settlement process is started at the settlement POS device, etc. within the customer's normal travel time (e.g., 1 to 5 minutes, etc.) from the registration POS device, etc. to the settlement sales information processing device (e.g., settlement POS device, etc.), so the facial information identity determination unit, etc. of the sales information management device can make determinations efficiently.

[0020] Preferably, when the high risk judgment unit of the sales information management system judges that the purchase target information of a customer contains high risk information, a warning message requesting the input of the customer's membership information is displayed on the display unit of the sales information processing device for registration, and the input membership information is stored in association with the customer's biometric information and is stored until the settlement process in the sales information processing device for settlement is completed, after which the customer's facial information is deleted.

[0021] According to the above configuration, when a customer purchases purchase target information (e.g., a product to be purchased, etc.) that includes high-risk information (e.g., high-risk product information, etc.), the customer is requested to input member information (e.g., member ID information, etc.) into a registration sales information processing device (e.g., a registration POS device, etc.), and the input member ID information, etc. is associated with the customer's biometric information (e.g., facial information, etc.) and stored, so that if the customer commits fraud, etc., the individual can be identified immediately. On the other hand, if the customer does not commit any fraud and completes the payment process using a payment sales information processing device (for example, a payment POS device), the customer's facial information and other data will be deleted. This also protects the customer's personal information.

[0022] Preferably, the registration sales information processing device of the sales information management system has a function change unit that causes the registration sales information processing device to function as the settlement sales information processing device, and when the high risk judgment unit determines that the customer's purchase target information contains high risk information, a warning message requesting the customer to enter their membership information is displayed on the display unit of the registration sales information processing device, and when the membership information is not entered, the function change unit operates to cause the registration sales information processing device to function as the settlement sales information processing device.

[0023] According to the above configuration, when member information (e.g., member ID information, etc.) is not entered, the function change unit (e.g., registration POS device change unit, etc.) operates and causes the registration sales information processing device (e.g., registration POS device, etc.) to function as a settlement sales information processing device (e.g., settlement POS device, etc.), thereby reliably preventing customer fraudulent behavior, etc.

[0024] According to the present invention, the object is to provide a method for controlling a sales information management system including a registration sales information processing device having a registration-side imaging device which is an imaging device that images a customer and is for inputting purchase object information that the customer plans to purchase, a plurality of settlement sales information processing devices having a settlement-side imaging device which is an imaging device that images the customer's biometric information and is configured so that the customer can perform settlement processing for the purchase object information themselves, a sales information management device arranged to be able to communicate with the registration sales information processing devices and the settlement sales information processing device, and the registration sales information processing device includes a registration-side customer information input unit which inputs customer membership information and a printing device which prints purchase object identification information that identifies each of the customer's purchase object information, wherein the customer's membership information is input to the settlement-side customer information input unit and the purchase object identification information input unit of the settlement sales information processing device, and a biometric information identity determination unit of the sales information management device determines whether the registration biometric information is the biometric information captured by the registration-side imaging device and the biometric information captured by the settlement-side imaging device, a member identity determination unit of the sales information processing device for settlement determines the identity of the member information input from the registration-side customer information input unit and the member information input from the settlement-side customer information input unit; a purchase object identification identity determination unit of the sales information management device determines the identity of the purchase object identification information input to the purchase object identification information input unit and the purchase object identification information printed by the printing device; and 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 object identification information input unit of the sales information processing device for settlement requests the input of the member information or the purchase object identification information, and the member identity determination unit determines the identity of the member information or the purchase object identification information, and the sales information management device deletes the stored biometric information when the settlement process of the sales information processing device is completed.

[0025] According to the present invention, the object is achieved by providing a sales information management system including a registration sales information processing device having a registration-side imaging device which is an imaging device for imaging a customer and for inputting purchase object information that the customer plans to purchase, a plurality of settlement sales information processing devices having a checkout-side imaging device which is the imaging device for imaging the customer's biometric information and configured to enable the customer to perform checkout processing for the purchase object information themselves, and a sales information management device arranged to be able to communicate with the registration sales information processing devices and the checkout sales information processing device, the registration sales information processing device having a registration-side customer information input unit for inputting customer membership information and a printing device for printing purchase object identification information that identifies each of the customer's purchase object information, the sales information management system including a function in which the customer's membership information is input into the checkout-side customer information input unit of the checkout sales information processing device and the purchase object identification information input unit, a biometric information identity determination unit of the sales information management device that determines whether the registration biometric information is the biometric information captured by the registration-side imaging device and the checkout biometric information is the biometric information captured by the checkout-side imaging device, a function of a member identity determination unit of the sales information processing device for settlement determining the identity of the member information input from the registration-side customer information input unit and the member information input from the settlement-side customer information input unit; a function of a purchase object identification identity determination unit of the sales information management device determining the identity of the purchase object identification information input to the purchase object identification information input unit and the purchase object identification information printed by the printing device; a function of the settlement-side customer information input unit or the purchase object identification information input unit of the sales information processing device for settlement requesting input of the member information or the purchase object identification information only when the biometric information identity determination unit cannot determine the identity of the biometric information; a function of the member identity determination unit determining the identity of the member information or the purchase object identification information; and a function of the sales information management device deleting the stored biometric information when the settlement process of the sales information processing device is completed. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0028] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are applied. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is specifically limited.

[0029] (Main components of POS management system 1) FIG. 1 is a schematic diagram showing the main configuration of a "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 a store or other store on an item-by-item basis at the time of sale.

[0030] As shown in FIG. 1, the system 1 includes a registration sales information processing device, for example, a "registration POS device 100a," which is installed in a store Z or the like. In this embodiment, a plurality of registered POS devices 100a are installed in store Z, but FIG. 1 shows only one of them, the registered POS device 100a, and the other registered POS devices have the same configuration. The registered POS device 100a is a device for inputting purchase information, such as a product to be purchased, that a customer C or the like plans to purchase at a store Z, and is input by, for example, a salesperson S at the store Z.

[0031] The system 1 also includes sales information processing devices for settlement that are installed in the store Z, such as settlement POS devices 200a, 200b. In this embodiment, two or more settlement POS devices 200a, 200b, etc. are installed in store Z, but Figure 1 shows only two of them, 200a, 200b, and the other settlement POS devices have the same configuration. The settlement POS device 200a or the like is configured to enable the customer C to carry out settlement processing for the products he / she intends to purchase at the store Z by himself / herself.

[0032] In other words, in this embodiment of the system 1, the items to be purchased are first input and registered at the registration POS device 100a operated by the store clerk S, and then the customer C moves to the settlement POS device 200a and performs the settlement process himself, which is a so-called ``semi-self-service system.''

[0033] In FIG. 1, the store Z includes a monitorable checkout sales information processing device, for example, a monitorable checkout POS device 300a. This monitorable settlement POS device 300a has a configuration similar to the settlement POS device 200a, etc., but is placed within the visible range of the store clerk S, who is the operator of the registered POS device 100a, etc., and is a device in a state where the execution status of the settlement process can be monitored by the registered POS device 100a. The functions of this monitorable settlement POS device 300a will be described later.

[0034] As shown in FIG. 1, the system 1 also includes a sales information management device, such as a management server 10. As shown in Figure 1, this management server 10 is arranged to be able to communicate with the registered POS device 100a, the 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, registered POS device 100a, settlement POS device 200a, etc. and monitorable settlement POS device 300a, etc. in Figure 1 have computers, each having a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a hard disk, etc., and are connected via a bus.

[0036] FIG. 2 is a schematic block diagram showing the main configuration of the registration POS device 100a of FIG. 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 of 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] As shown in FIG. 2, the control unit 101 also controls a display unit that displays various information, such as a "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 a "registered POS side information input unit 105," a printing device that prints purchase target identification information that identifies the products that customer C intends to purchase, such as "settlement receipt information," such as a "printer 106," and a "registered POS side various information storage unit 107" that stores various information.

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

[0039] In addition, as shown in Figure 3, the control unit 201 controls a "checkout POS side display 204" that displays various information, a checkout side customer information input unit such as a "checkout POS side information input unit 205" that inputs customer C's member ID information, and a purchase item identification information input unit such as a "checkout receipt input unit 206" that inputs checkout receipt information. Furthermore, the control unit 201 also controls a "payment POS side various information storage unit 207" that stores various information.

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

[0041] In addition, as shown in Figure 4, the control unit 11 also controls the ``customer face related information storage unit 15,'' ``high risk product judgment unit (program) 16,'' ``high risk product information storage unit 17,'' ``member ID information storage unit 18,'' ``monitored settlement POS device presence / absence judgment unit (program) 19,'' ``settlement POS device change unit (program) 20,'' ``travel time processing unit (program) 21,'' ``face identity judgment unit (program) 22,'' ``member identity judgment unit (program) 23,'' and ``settlement receipt sheet identity judgment unit (program) 24,'' and the contents of these will be described later.

[0042] 5 to 9 are schematic flowcharts showing examples of main operations of the system 1. FIG. In this embodiment, an example in which a customer C purchases a product at a store Z will be described below. (Preliminary process) First, if customer C has his / her own member ID information, he / she stores his / her member ID information, for example, "123456", in the "member ID information storage unit 18" of management server 10 in advance. This completes the preliminary process.

[0043] (Example of operation of this system 1) First, in step (hereinafter referred to as "ST") 1 of FIG. 5, customer C brings products he or she plans to purchase, such as vegetables, meat, or high-quality whiskey. A salesperson S of the store Z inputs and registers the products that the customer C intends to purchase using the registration POS device 100a that the salesperson 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 the 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 facial information (facial image) (an example of registration biometric information)." The management server 10 stores the "enrollment face image" of the customer C in the "customer face related information storage unit 15" shown in FIG.

[0045] In the present invention, "biometric information" is not limited to facial images, but may also include physical characteristics such as hand length and leg length, clothing characteristics such as hat color and clothing color, and the like.

[0046] Next, in ST3, when the store clerk S inputs information about the product to be purchased (vegetables, meat, high-quality whiskey, etc.) into the registered POS device 100a, the registered POS device 100a transmits the information about the product to be purchased to the management server 10. The management server 10 stores the "purchase intention product information" in association with the "customer face image" of the customer C in the "customer face related information storage unit 15" of FIG.

[0047] 10 and 11 are schematic explanatory diagrams showing the transition of the "customer face related information" stored in the customer face related information storage unit 15. FIG. FIG. 10(1) shows customer face-related information (part 1) in ST3, in which face information of customer C at the time of registration and products to be purchased are stored in association with each other.

[0048] Next, the process proceeds to ST4. In ST4, the "high risk product determination unit (an example of a high risk determination unit) 16" in FIG. 4 of the management server 10 operates and refers to the information in the "high risk product information storage unit 17" in FIG. 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 are particularly likely to be subject to fraud, such as high-priced products and products that can be resold, and these products are stored as "high-risk products."

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

[0050] In addition, in this embodiment, the high-risk product determination unit not only determines whether each individual product that customer C plans to purchase is a ``high-risk product,'' but may also determine whether the total amount of the products that customer C plans to purchase is equal to or greater than a predetermined amount.In this case, if the total amount is equal to or greater than 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 a message saying "Payment should be made at the monitorable settlement POS device 300a," along with a "warning message" requesting the input of customer C's "member ID information."

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

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

[0054] The customer face related information (part 2) in the "customer face related information storage unit 15" in ST7 is as shown in FIG. 10(2). As shown in FIG. 10(2), in the customer face related information (part 3), the face information at the time of registration of customer C, the product information to be purchased, and the information of "monitored POS only" are stored in association with each other.

[0055] Next, the registration POS device 100a requests the input of member ID information of customer C. Once the member ID information is input in ST8, the process proceeds to ST9. In ST9, when the member ID information (123456) is input to 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.

[0056] Next, the process proceeds to ST10. In ST10, the management server 10 determines whether the member ID information stored in the "member ID information storage unit 18" is already registered, and if it is already registered, stores the member ID information in the customer face related information storage unit 15 in association with information on the product to be purchased, etc. FIG. 10(3) is a schematic explanatory diagram showing "customer face related information (part 3)" in the customer face related information storage unit 15 in ST10. As shown in FIG. 10(3), the "member ID information (for example, 123456)" is stored in association with the face information and product information of customer C at the time of registration. In this embodiment, if customer C has already registered his / her member ID information, he / she will not be forced to process the payment using the monitorable payment POS device 300a, as described below, but will instead process the payment using a normal payment POS device 200a, etc. This is because customer C has already been identified by the management server 10, and the possibility of fraudulent activity or the like being committed is extremely low.

[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 to customer C "payment receipt information" that identifies information about the products that customer C has purchased. The registered POS device 100a also transmits the "payment receipt information" to the management server 10.

[0058] Next, the process proceeds to ST12. In ST12, the management server 10 stores the "payment receipt information" in the customer face related information storage unit 15 in association with information on the intended product to be purchased, etc.

[0059] FIG. 10(4) is a schematic explanatory diagram showing the "customer face related information (part 4)" in the customer face related information storage unit 15 in ST12. As shown in FIG. 10(4), customer C's facial information at the time of registration, information on the product to be purchased, information only from the monitored POS, and member ID information are stored in association with "payment receipt information."

[0060] After ST12, proceed to ST13. In ST13, the "monitored settlement POS device presence / absence determination unit 19" of the management server 10 shown in FIG. 4 operates to determine whether there is a "monitored settlement POS device 300a" ​​for which the currently unused customer C should settle his / her account.

[0061] In ST14, if there is a "monitoring-enabled settlement POS device 300a" ​​for which customer C, who is not currently using the device, should make a settlement, the process proceeds 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 a message indicating that there is an unused monitorable settlement POS device 300a, specifically, the identification number 110 (for example, an example of identification information) of the monitorable settlement POS device 300a.

[0062] Then, the store clerk S operating the registered POS device 100a or the like informs the customer C of the identification number 110 or the like of one or more unused monitorable settlement POS devices 300a or the like. In this way, customer C is notified by store clerk S and can reliably and easily select the monitorable settlement POS device 300a, etc. with which he or she should settle the transaction, if there is one, from among the monitorable settlement POS device 300a, etc., or if there are multiple, from among multiple monitorable settlement POS devices 300a, etc.

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

[0064] On the other hand, if there is no unused monitorable checkout POS device 300a or the like in ST14, the process proceeds to ST16. In ST16, the "settlement POS device change unit (an example of a change unit) 20" in Figure 4 of the management server 10 operates, temporarily changing the settlement POS device 200a, etc. that is located closest to the registered POS device 100a to a monitorable settlement POS device 300a, and transmitting its identification number (e.g., 103) to the registered POS device 100a.

[0065] Next, the process proceeds to ST 17. In ST 17, the registered POS device 100a displays the identification number on the registered POS display 104 and / or displays it on the payment receipt on which payment receipt information is printed. Therefore, customer C can always process the payment at the monitorable payment POS device 300a, and it is possible to prevent situations such as waiting for payment due to a lack of equipment from occurring.

[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 contains high-risk product information, the registered POS side display 104 of the registered POS device 100a displays a message indicating that payment should be made at the ``monitored settlement POS device 300a.'' This monitorable settlement POS device 300a is placed within the visible range of the store clerk S who is the operator of the registered POS device 100a, and is configured so that the registered POS device 100a can monitor the execution status of the settlement process.

[0067] Therefore, if the items that customer C intends to purchase include high-risk product information such as high-priced items or items that can be resold, an operator such as store clerk S at store Z can force customer C to process the payment at a monitorable payment POS device where the payment process of customer C can be visually observed, thereby preventing fraudulent acts such as taking away the items to be purchased without paying. In other words, the store clerk S, who is the operator of the registered POS device 100a, can monitor the monitorable settlement POS device 300a, and can therefore confirm whether or not the customer C is actually performing the settlement process, thereby reliably preventing the occurrence of fraudulent activities, etc. Furthermore, since the management server 10 has a high-risk product judgment 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, etc., and can more accurately recognize the occurrence of fraudulent activities, etc.

[0068] On the other hand, if it is determined in ST5 that the purchase does not contain any high-risk products, the registered POS device 100a requests the customer C to input his / her member ID information. If member ID information is entered in ST18, the process proceeds to ST19. In ST19, when the member ID information (for example, 123456) is input to 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 stored in the "member ID information storage unit 18" is already registered, and if it is already registered, stores the member ID information in the "customer face related information storage unit 15" in association with information on the product to be purchased, etc.

[0070] FIG. 11(1) is a schematic explanatory diagram showing "customer face related information (part 5)" in the customer face related information storage unit 15 in ST20. As shown in FIG. 11(1), the "member ID information" is stored in association with the face information and product information of customer C at the time of registration.

[0071] On the other hand, if no member ID information is entered in ST18, the process proceeds to ST21. In ST21, the printer 106 of the registered POS device 100a prints out and outputs to the customer C "payment receipt information" that identifies the product information that the customer C intends to purchase. The registered POS device 100a also 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 in association with the intended purchase product information and the like.

[0073] FIG. 11(2) is a schematic explanatory diagram showing "customer face related information (part 6)" in the customer face related information storage unit 15 in ST22. As shown in FIG. 11(2), the facial information at the time of registration of customer C and the product information to be purchased are stored in association with the "payment receipt information."

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

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

[0076] FIG. 11(3) is a schematic explanatory diagram showing "customer face related information (part 7)" in the customer face related information storage unit 15 in ST24. As shown in FIG. 11(3), the "face information at checkout" is stored in association with customer C's face information at the time of registration, product information to be purchased, member ID information, or checkout receipt information.

[0077] Next, the process proceeds to ST25. In ST25, the "travel time processing unit 21" of the management server 10 shown in FIG. 4 operates to determine whether the time when the "payment facial image" of customer C was acquired is within, for example, one minute from the time when customer C completed the registration process at the registered POS device 100a.

[0078] That is, it is determined whether customer C moved from the registered POS device 100a to the settlement POS device 200a, etc., and whether a "face image at the time of payment" was captured within the normal travel time (e.g., 1 minute) for the customer from the registered POS device 100a to the settlement POS device 200a, etc. If it is determined in ST26 that the travel time is not within the normal travel time, the person is not subject to the "face identity determination" described below (ST28), and the process proceeds to ST31 described below, where the person is asked to enter member ID information.

[0079] In this embodiment, by adopting such a configuration, it is possible to eliminate unnecessary processing in the system 1, and to perform processing efficiently. That is, by limiting the objects for which identity is to be determined, the accuracy of the determination can be improved and processing can be performed quickly.

[0080] On the other hand, if it is determined in ST26 that the image has been captured within the normal movement time, the process proceeds to ST27. In ST27, the "face identity determination unit (an example of a biometric information identity determination unit) 22" in Figure 4 of the management server 10 operates to determine whether the "face information at checkout" is identical to the "face information at registration" or whether it is difficult to determine the identity.

[0081] In this embodiment, identity is determined mainly based on facial information, but the present invention is not limited to this, and identity may be determined comprehensively by adding information such as face, clothing, and limb proportions. In this case, identity can be determined more reliably than when only facial information is used. In this case, since there is no need to make a detailed judgment on face information, the accuracy of the identity judgment can be improved.

[0082] On the other hand, if it is not determined in ST26 that the image was 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 it is determined in ST29 that the facial information at checkout is identical to the facial information at registration, proceed to ST30. In ST30, the management server 10 transmits the "information on the product to be purchased" associated with the "face image at the time of registration" etc. in the customer face-related information storage unit 15 that has been determined to be "identical" to the settlement POS device 200a etc. or the monitorable settlement POS device 300a, and the settlement POS device 200a etc. or the monitorable settlement POS device 300a performs the settlement process.

[0084] Therefore, customer C can simply stand in front of the checkout POS device 200a or the monitorable checkout POS device 300a to complete the checkout process for his / her purchased items, allowing customer C to quickly checkout with minimal effort.

[0085] In this embodiment, when the monitorable settlement POS device 300a starts settlement processing, a notification to that effect is sent to the registered POS device 100a. Therefore, the store clerk S or the like who is the operator of the registered POS device 100a can accurately know whether the payment for the products including the high-risk products has started or remains unpaid.

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

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

[0088] Next, the process proceeds to ST33. In ST33, the "member identity determination unit 23" of the management server 10 operates to refer to the customer face related information storage unit 15 to determine whether the member ID information is identical, and if it is identical, transmits the product information intended to be purchased by customer C 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, proceed to ST34. In ST34, the settlement receipt information is entered into the settlement POS device 200a or the monitorable settlement POS device 300a, etc. The information is then sent to the management server 10.

[0090] Next, the process proceeds to ST35. In ST35, the "payment receipt identity determination unit (an example of a purchase item identification identity determination unit) 24" in FIG. 4 of the management server 10 operates to refer to the customer face related information storage unit 15 of customer C, determine whether the "payment receipt information" is identical, and if it is identical, send the information about the product that customer C intends to purchase to the payment POS device 200a or the monitorable payment POS device 300a.

[0091] After ST33 and ST35, the process proceeds to ST36. In ST36, the checkout POS device 200a or the monitorable checkout POS device 300a performs checkout processing based on the product information of customer C that he / she plans to purchase. Thus, according to this embodiment, even when the "facial identity determination unit 22" does not determine identity, customer C can reliably perform the settlement process using the member ID information or settlement receipt information.

[0092] After ST28, ST30, and ST36, the process proceeds to ST37. In ST37, when the payment process is completed, the management server 10 deletes the face image at registration and the face image at payment if they are stored in the customer face-related information storage unit 15. Therefore, in this embodiment, the personal information of customer C can be effectively protected.

[0093] On the other hand, if customer C commits fraud or the like before the payment process is completed, the facial image at registration and the facial image at payment are not immediately deleted. Therefore, in this embodiment, it is possible to identify an individual from these facial images and member IDs, etc., and it becomes possible to quickly provide compensation for damages at store Z, etc.

[0094] (First Modification of the Present Embodiment) A first modification of this embodiment will be described below. Since most of the configuration of the first modification is similar to that of the above-described embodiment, the following description will mainly focus on the differences. In the first modified example, unlike this embodiment, the registration POS device 100a has a "registration POS function change unit (an example of a function change unit)" that causes the registration POS device 100a to function as the settlement POS device 200a or the like.

[0095] In this case, when the product that customer C intends to purchase contains high-risk product information and member ID information is not entered, the "registered POS function change unit" of the registered POS device 100a will be activated, causing the registered POS device 100a to function as a settlement POS device 200a, etc., and the settlement process will also be carried out on the registered POS device 100a where customer C has registered the product that he intends to purchase.

[0096] With this configuration, the customer C performs the payment process in front of the store clerk S at the registered POS device 100a where the product to be purchased has been registered, so that fraudulent acts by the customer can be reliably prevented. In this case, the registered POS device 100a may print and eject the settlement receipt information, and the customer C may then input the settlement receipt information into the registered POS device 100a to carry out the settlement process. In this case, the payment process is carried out by the customer C, so the burden on the store clerk S is not increased, and the process can be carried out efficiently.

[0097] (Second Modification of the Present Embodiment) A second modification of this embodiment will be described below. Since much of the configuration of the second modification is similar to that of the embodiment described above, the following description will mainly focus on the differences. In the first modified example, unlike the present embodiment, products with higher prices than the high-risk product information of the present embodiment (for example, a single product with a price of 100,000 yen or more) are stored as "valuable products."

[0098] If this "valuable item" is included in the items the customer plans to purchase, as in the first variant example, the "registered POS function change unit" of the registered POS device 100a will operate, causing the registered POS device 100a to function as a settlement POS device 200a, etc., and the settlement process will also be performed on the registered POS device 100a where customer C registered the items he plans to purchase. Therefore, this modification can effectively protect extremely valuable commodities from fraud.

[0099] (Third Modification of the Present Embodiment) A third modification of this embodiment will be described below. Since much of the configuration of the third modification is similar to that of the above-described embodiment, the following description will mainly focus on the differences. In the third variant, unlike the present embodiment, if all the settlement POS devices 200a, etc. are in use and there is no settlement POS device 200a, etc. that customer C can immediately use, the "registered POS function change unit" of the registered POS device 100a will operate as in the first variant, causing the registered POS device 100a to function as the settlement POS device 200a, etc., and the settlement process will also be performed at the registered POS device 100a where customer C has registered the products he wishes to purchase. With this configuration, this modification allows customer C to quickly complete the payment process.

[0100] In the above-described embodiment, an example has been given in which the invention is realized as a device, but the invention is not limited to this, and the invention may be distributed as a program that can be executed by a computer, stored on a storage medium such as a magnetic disk (e.g., a floppy (registered trademark) disk, a hard disk), an optical disk (e.g., a CD-ROM, a DVD), a magneto-optical disk (MO), or a semiconductor memory.

[0101] The storage medium may be any medium that can store the program and is readable by a computer, and the storage format of the storage medium is not particularly limited.

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

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

[0104] Furthermore, the computer in the present 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 a system in which multiple devices are connected to a network.

[0105] Furthermore, the term "computer" in this invention is not limited to a personal computer, but also includes an arithmetic processing unit, a microcomputer, etc. included in information processing equipment, and is a general term for equipment or devices that can realize the functions of this invention by a program.

[0106] The above describes the embodiments of the present invention. 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 arbitrarily combined in a different manner from the above. [Explanation of symbols]
