[0132] Fig. 8 is a sequence diagram illustrating an information processing procedure of the transaction support system S according to the embodiment. Fig. 8 illustrates an information processing procedure for determining the age of the user of the user terminal 2 based on the code symbol.

[0133] The processing circuit 21 of the user terminal 2 starts an application for an electronic receipt service based on a user operation (ACT101). The processing circuit 21 may request member information from the server 1 based on the start of the application for the electronic receipt service.

In ACT103, for example, the processing circuit 21 refers to the member information stored in the member information storage area 231, and generates a code symbol indicating the member code based on the member code including the option code.

[0136] The processing circuit 21 of the user terminal 2 displays the code symbol on the display device 27 (ACT104). ACT104 may be processing by the display processing unit 212.

[0137] The POS terminal 3 reads the code symbol via a scanner 35 or the like. The processing circuit 30 of the POS terminal 3 acquires the membership code recorded in the code symbol (ACT111). ACT111 may be a process performed by the acquiring unit 301.

[0138] The processing circuit 30 of the POS terminal 3 determines the age of the user of the user terminal 2 based on the membership code (ACT112). ACT112 may be processed by the determination unit 302. In ACT112, for example, the processing circuit 30 determines whether the user's age has been set based on the age identification code. In this example, the processing circuit 30 determines that the user's age has been set if "1" or "2" is set in the age identification code. The processing circuit 30 may determine that the user's age has not been set if the age identification code is set to an initial value.

[0139] The processing circuit 30 of the POS terminal 3 sets the operation mode based on the determination result (ACT113). ACT113 may be processing by the processing unit 303. In ACT113, for example, if the member's age is set, the processing circuit 30 sets the operation mode to the transaction non-support mode. If the member's age is not set, the processing circuit 30 sets the operation mode to the transaction support mode.

[0140] The processing circuit 30 of the POS terminal 3 displays a notification based on the determination result (ACT114). ACT114 may be processing by the processing unit 303. In ACT114, for example, when the member's age is set, the processing circuit 30 displays a notification indicating that the age has been verified on the first display device 37-1. When the member's age is set, the processing circuit 30 may display a notification indicating that the age has been verified on the second display device 37-2. The processing circuit 30 may display the notification temporarily, or may display it until one transaction is completed.

[0141] The processing circuit 30 of the POS terminal 3 processes product registration for one or more transaction products (ACT115). ACT115 may be processing by the registration processing unit 304. In ACT115, for example, the processing circuit 30 acquires a product code of the transaction product based on the reading of the code symbol of the transaction product by the scanner 35. The processing circuit 30 may acquire the product code of the transaction product based on the selection of the transaction product using the input device 36. The processing circuit 30 outputs a registration request including the product code of the transaction product to the server 1. The registration request is a request for causing the server 1 to execute product registration for the transaction product. The server 1 adds data regarding the transaction product to the data regarding the transaction based on the product code of the transaction product included in the registration request. The server 1 may refer to the data of the product master. The data of the product master is data including various information regarding the product, such as a product code, a price, and a product name, for each product. Outputting a registration request including the product code of the transaction product to the server 1 is an example of processing product registration for the transaction product.

[0142] According to this example, the processing circuit 30 can verify the age of the user of the user terminal 2 based on the membership code. Therefore, even if the product to be traded is an age verification product, the processing circuit 30 does not display a message indicating that age verification is required. The user of the POS terminal 3 does not need to verify the age of the member. This allows the transaction support system S to reduce the workload of store clerks in registering products.

[0143] The processing circuit 30 of the POS terminal 3 performs a payment process for the transaction (ACT116). ACT116 may be a process by the payment processing unit 305. In ACT116, for example, the processing circuit 30 performs the payment process by a known technique. Note that before performing the payment process, the processing circuit 30 may display a notification indicating that age verification has been completed on the first display device 37-1. The processing circuit 30 may display a notification indicating that age verification has been completed on the second display device 37-2. The processing circuit 30 may temporarily display the notification.

[0144] In the above example, the POS terminal 3 reads the code symbol indicating the membership code before registering the product, but the present invention is not limited to this. For example, the POS terminal 3 may read the code symbol indicating the membership code during product registration. For example, a case where the product to be traded is an age verification product will be described. When processing product registration for the product to be traded, the processing circuit 30 displays a notice indicating that age verification is required on the first display device 37-1. When the processing circuit 30 reads the product code for the product to be traded, the processing circuit 30 displays a notice indicating that age verification is required on the first display device 37-1. Based on the notice indicating that age verification is required, the user of the POS terminal 3 prompts the user of the user terminal 2 to present the membership code. The user of the user terminal 2 inputs a code display instruction. The processing circuit 21 of the user terminal 2 performs processes from ACT102 to ACT104. The processing circuit 30 of the POS terminal 3 performs processes from ACT111 to ACT112. Processing circuitry 30 may display a notification indicating that age verification has been completed on first display device 37-1. Processing circuitry 30 may display a notification indicating that age verification has been completed on second display device 37-2.

[0145] According to this example, even if it is necessary to verify the age of the user (customer) of the user terminal 2 during product registration, the processing circuit 30 of the POS terminal 3 can verify the age of the user (customer) of the user terminal 2 based on the membership code. Therefore, the user (store clerk) of the POS terminal 3 does not need to verify the age of the user (customer) of the user terminal 2 using an identification card or the like. This allows the transaction support system S to reduce the workload of store clerks in product registration.

[0146] In addition, the processing circuit 21 of the user terminal 2 may display a moving image together with the code symbol in ACT104. The moving image is, for example, an image that changes in a time series. The moving image includes, for example, an image of a character and a background image. The character image includes, for example, an image in which the display mode of a part of the character changes. The background image includes, for example, an image in which the display mode of a part of the background changes. The change in the display mode includes a change in color, size, brightness or luminance, background pattern, frame color, or blinking display. The background image includes an image showing a specific service. The specific service includes, for example, a service that allows recipe search, a service that displays a shopping list, and the like. The background image includes a background image unique to each user (customer). The background image unique to each user includes an image that displays information selected by the user. The background image unique to each user includes, for example, a service that displays a frequently used store selected by the user, information on a store visited, and a service that displays a coupon selected as a favorite by the user. In this case, in ACT111, in one example, the user of the POS terminal 3 visually checks the movement of the image, and if there is no movement, the code symbol is not read. According to this example, the processing circuit 21 of the user terminal 2 can display a moving image together with the code symbol. Therefore, if there is no movement in the image, the user of the POS terminal 3 can not read the code symbol. This allows the transaction support system S to prevent fraud, such as using a code symbol saved by a screenshot or the like.

[0147] In another example, a user of the POS terminal 3 takes an image via the camera 33. The processing circuit 30 of the POS terminal 3 determines whether the image has changed over time based on the image data. If the image has changed, the processing circuit 30 performs processing based on the acquisition of the membership code. If the image has not changed, the processing circuit 30 does not perform processing based on the acquisition of the membership code. According to this example, the processing circuit 30 of the POS terminal 3 determines the movement of the image, and if there is no movement in the image, does not perform processing based on the acquisition of the membership code. Therefore, the transaction support system S can prevent fraud such as having a user verify their age using a code symbol saved by a screenshot or the like.

[0148] In addition, the processing circuit 30 may determine whether the user's age is 20 years or more based on the age identification code in ACT112. In this example, the processing circuit 30 determines that the user's age is 20 years or more when the age identification code is set to "1". The processing circuit 30 determines that the user's age is less than 20 years old when the age identification code is set to "2". A case where the user's age is 20 years or more will be described. In ACT115, the processing circuit 30 determines that the user's age is 20 years or more when the age identification code is set to "1", and processes the product registration without performing age verification even if the product to be traded is an age verification product. A case where the user's age is less than 20 years old will be described. In ACT115, the processing circuit 30 may display a warning message indicating that the purchase of the product to be traded is restricted on the first display device 37-1 when the product to be traded is an age verification product. In this case, the processing circuit 30 may display the warning message on the second display device 37-2.

[0149] According to this example, the processing circuit 30 can display a warning message when a customer who is restricted from purchasing the transaction product attempts to purchase the transaction product. The processing circuit 30 can process the transaction according to the age identification code. This allows the transaction support system S to prevent the purchase of the product that is restricted from being purchased.

[0150] Fig. 9 is a sequence diagram illustrating an information processing procedure of the transaction support system S according to the embodiment. Fig. 9 illustrates an information processing procedure for determining the age of the user of the user terminal 2 based on a code symbol. In this example, it is assumed that the user of the user terminal 2 and the user of the self-service POS terminal 4 are the same customer.

[0151] The processing circuit 21 of the user terminal 2 starts an application for an electronic receipt service based on a user's operation, similar to ACT101 (ACT201). The processing circuit 21 may request member information from the server 1 based on the fact that the application for the electronic receipt service has been started. In this case, the processing circuit 21 may output a request including a member ID stored in the member information storage area 231 to the server 1, for example. The processing circuit 21 may update the member information stored in the member information storage area 231 based on the member information acquired from the server 1. The processing circuit 21 may request member information from the server 1 at a fixed period.

[0152] The processing circuit 21 of the user terminal 2 receives the code display instruction (ACT202), similarly to ACT102. ACT202 may be processing by the code processing unit 211.

[0153] The processing circuit 21 of the user terminal 2 generates a code symbol based on the code display instruction (ACT203), similarly to ACT103. ACT203 may be processing by the code processing unit 211.

[0154] The processing circuit 21 of the user terminal 2 displays the code symbol on the display device 27 (ACT204), similarly to ACT104. ACT204 may be processing by the display processing unit 212.

[0155] The self-service POS terminal 4 reads the code symbol via a scanner 45 or the like. The processing circuit 40 of the self-service POS terminal 4 acquires the membership code recorded in the code symbol (ACT211) in the same manner as in ACT111. ACT211 may be processing by the acquiring unit 401.

[0156] The processing circuit 40 of the self-service POS terminal 4 determines the age of the user of the user terminal 2 based on the membership code, similar to ACT112 (ACT212). ACT212 may be processed by the determination unit 402. In ACT212, for example, the processing circuit 40 determines whether or not the user's age has been set based on the age identification code. In this example, if "1" or "2" is set in the age identification code, the processing circuit 40 determines that the user's age has been set. If the age identification code is set to an initial value, the processing circuit 40 may determine that the user's age has not been set.

[0157] The processing circuit 40 of the self-service POS terminal 4 sets the operation mode based on the determination result, similarly to ACT113 (ACT213). ACT213 may be processed by the processing unit 403. In ACT213, for example, if the member's age is set, the processing circuit 40 sets the operation mode to the non-transaction support mode. If the member's age is not set, the processing circuit 40 sets the operation mode to the transaction support mode.

[0158] Based on the determination result, the processing circuit 40 of the self-service POS terminal 4 outputs information related to the notification to the store terminal 5. The process of outputting the information related to the notification may be a process by the output unit 406. For example, when the age of the member is set, the processing circuit 40 outputs information for causing the store terminal 5 to display a notification indicating that the age has been verified.

[0159] The processing circuit 51 of the store terminal 5 acquires information for displaying a notification indicating that age verification has been completed from the self-service POS terminal 4. The process of acquiring information for displaying the notification may be a process performed by the communication processing unit 510. The processing circuit 51 of the store terminal 5 displays a notification on the display device 57 based on information for displaying a notification indicating that age verification has been completed (ACT221). ACT221 may be processing by the display processing unit 511. The notification may be, for example, a text message such as "Age Verification Completed." The processing circuit 51 may display the notification temporarily, or may display it until one transaction is completed.

[0160] According to this example, the processing circuit 51 can display a notification on the display device 57 indicating that age verification has been completed. Therefore, the user of the store terminal 5 can recognize that age verification has been completed for the customer using the self-service POS terminal 4. The user of the store terminal 5 does not need to perform age verification for the customer using the self-service POS terminal 4, even when the customer purchases a product requiring age verification. This allows the transaction support system S to reduce the workload of the store clerk in registering products.

[0161] The processing circuit 40 of the self-service POS terminal 4 displays a notification based on the determination result, similar to ACT114 (ACT214). ACT214 may be processed by the processing unit 403. In ACT214, for example, when the member's age is set, the processing circuit 40 displays a notification indicating that the age has been verified on the display device 47. The processing circuit 40 may display the notification temporarily, or may display it until one transaction is completed.

[0162] The processing circuit 40 of the self-service POS terminal 4 processes merchandise registration for one or more transaction merchandise items (ACT215), similarly to ACT115. ACT215 may be processing by the registration processing unit 404.

[0163] According to this example, the processing circuit 40 can verify the age of the user of the user terminal 2 based on the membership code. Therefore, when the acquired age identification code is set to "1", the processing circuit 40 determines that the user's age is 20 years or older, and does not display a message indicating that age verification is required even if the product to be transacted is an age verification product. The store clerk does not need to verify the age of the user of the user terminal 2. This allows the transaction support system S to reduce the workload of the store clerk in registering products.

[0164] The processing circuit 40 of the self-service POS terminal 4 performs payment processing for the transaction (ACT216), similar to ACT116. ACT216 may be processing by the payment processing unit 405. In ACT216, for example, the processing circuit 40 performs payment processing using a known technique. Note that before performing payment processing, the processing circuit 40 may display a notification on the display device 47 indicating that age verification has been completed. The processing circuit 40 may temporarily display the notification.

[0165] In the above example, the self-service POS terminal 4 reads the code symbol indicating the membership code before registering the product, but the present invention is not limited to this. For example, the self-service POS terminal 4 may read the code symbol indicating the membership code during product registration. For example, a case where the product to be traded is an age verification product will be described. When processing product registration for the product to be traded, the processing circuit 40 displays a notification indicating that age verification is required on the display device 47. The user of the user terminal 2 inputs a code display instruction based on the notification indicating that age verification is required. The processing circuit 21 of the user terminal 2 performs processes from ACT202 to ACT204. The processing circuit 40 of the self-service POS terminal 4 performs processes from ACT211 to ACT212. The processing circuit 40 may display a notification indicating that age verification has been completed on the display device 47.

[0166] According to this example, even if age verification of the user of the user terminal 2 is required during product registration, the processing circuit 40 of the self-service POS terminal 4 can verify the age of the user (customer) of the user terminal 2 based on the membership code. Therefore, the store clerk does not need to verify the age of the user of the user terminal 2 using an identification card or the like. This allows the transaction support system S to reduce the workload of the store clerk in product registration.

[0167] In addition, the processing circuit 21 of the user terminal 2 may display a moving image together with the code symbol in ACT204. The moving image is, for example, an image that changes in a time series. The moving image includes, for example, an image of a character and a background image. The character image includes, for example, an image in which the display mode of a part of the character changes. The background image includes, for example, an image in which the display mode of a part of the background changes. The change in the display mode includes a change in color, size, brightness or luminance, background pattern, frame color, or blinking display. In this case, in ACT211, the user of the self-POS terminal 4 takes an image via the camera 43. The processing circuit 40 of the self-POS terminal 4 determines whether the image has changed in a time series based on the image data. If the image has changed, the processing circuit 40 performs processing based on the acquisition of the membership code. If the image has not changed, the processing circuit 40 does not perform processing based on the acquisition of the membership code. According to this example, the processing circuit 40 determines the movement of the image, and if there is no movement in the image, does not perform processing based on the acquisition of the membership code. Therefore, the transaction support system S can prevent fraudulent practices such as age verification using code symbols saved as screenshots or the like.

[0168] In addition, the processing circuit 40 may determine whether the user's age is 20 years or more based on the age identification code in ACT212. In this example, when the age identification code is set to "1", the processing circuit 40 determines that the user's age is 20 years or more. When the age identification code is set to "2", the processing circuit 40 determines that the user's age is less than 20 years old. A case where the user's age is 20 years or more will be described. In ACT215, the processing circuit 40 processes the product registration without performing age verification even if the product to be traded is an age verification product. A case where the user's age is less than 20 years old will be described. In ACT215, when the product to be traded is an age verification product, the processing circuit 40 may display a warning message on the display device 47 indicating that the purchase of the product to be traded is restricted.

[0169] According to this example, the processing circuit 40 can display a warning message when a customer who is restricted from purchasing the transaction product attempts to purchase the transaction product. The processing circuit 40 can process the transaction according to the age identification code. This allows the transaction support system S to prevent the purchase of the transaction-restricted product.

[0170] (Example) FIG. 10 is a diagram showing a display example of the user terminal 2 according to the embodiment. 10 is a diagram showing an image R including a code symbol displayed on the display device 27. The image R includes a code symbol display area Ra and a character display area Rb.

The product registration image Ima shows a product registration image when a membership code is read by the self-service POS terminal 4 before product registration is performed. The product registration image Ima includes a notification display area Ara, a transaction details display area Aa, and a total amount display area Ab.

[0174] The notification display area Ara is an area that shows a notification based on the membership code. In the example of FIG. 11, it is assumed that the self-service POS terminal 4 has determined that the member's age has been set based on the membership code. The notification display area Ara includes a message indicating "age verified." The display device 47 may display the message indicating "age verified" temporarily, or may display it until product registration is completed. Note that the display device 47 does not have to display the message indicating "age verified."

[0175] The transaction details display area Aa is an area for displaying information regarding transaction details. The total price display area Ab is an area for displaying the total price of registered products.

[0176] According to this example, the processing circuit 40 can notify the customer of the result of age verification based on the membership code. Therefore, the customer can recognize that age verification has been performed based on the membership code. In this way, the transaction support system S can improve the convenience of customers in registering products by eliminating the need for a store clerk to verify the customer's age.

[0177] FIG. 12 is a diagram showing a display example of the self-service POS terminal 4 according to the embodiment. 12 is a diagram showing a product registration image Imb displayed on the display device 47. The product registration image Imb shows a product registration image when a membership code is read by the self-service POS terminal 4 before product registration is performed. The product registration image Imb includes a notification display area Arb and a checkout button Ba.

[0178] The notification display area Arb is an area that shows a notification based on the membership code. In the example of FIG. 12, it is assumed that the self-service POS terminal 4 has determined that the member's age has been set based on the membership code. The notification display area Arb includes a message indicating "age verified." The display device 47 temporarily displays a message indicating "age verified" in the notification display area Arb by displaying a pop-up or the like based on the fact that a product requiring age verification has been registered.

[0179] The checkout button Ba is an operation key for inputting an instruction to proceed to checkout. The checkout button Ba is an operation key for declaring to the processing circuit 40 that checkout will be executed. When the checkout button Ba is operated by the user of the self-service POS terminal 4, the display device 47 displays the payment processing image Imf shown in FIG.

[0180] According to this example, when an age verification product is registered, the processing circuit 40 can notify the customer of the result of age verification of the customer based on the membership code. Therefore, the customer can recognize that age verification by a store clerk is not required even if the product to be traded is an age verification product. In this way, the transaction support system S can increase the convenience of customers in registering products by eliminating the need for a store clerk to verify the age.

[0181] FIG. 13 is a diagram showing a display example of the self-service POS terminal 4 according to the embodiment. 13 is a diagram showing a product registration image Imc displayed on the display device 47. The product registration image Imc shows a product registration image when a product is registered before a membership code is read in the self-service POS terminal 4. The product registration image Imc includes a notification display area Arc and a checkout button Ba.

[0182] The notification display area Arc is an area that shows a notification based on the membership code. The notification display area Arc includes a message indicating that age verification is required. The notification display area Arc may include a message indicating that the membership code needs to be read. The display device 47 displays a message indicating that age verification is required in the notification display area Arc by displaying a pop-up or the like based on the registration of an age verification product. The display device 47 may display the message until an operation is performed by a store clerk. The display device 47 may display the message at the self-service POS terminal 4 until the membership code is read.

[0183] A user of the self-service POS terminal 4 operates the user terminal 2 to display a code symbol indicating a membership code on the display device 27. The user causes the self-service POS terminal 4 to read the code symbol via the scanner 45. The self-service POS terminal 4 reads the code symbol and performs a determination regarding the age based on the acquired code. In the example of FIG. 13, it is assumed that the self-service POS terminal 4 has determined that the age of the member has been set based on the membership code. Based on the determination, the display device 47 displays the product registration image Imd shown in FIG. 14. In this case, the self-service POS terminal 4 may output a notification based on the determination result to the store terminal 5.

[0184] According to this example, the processing circuit 40 can prompt the customer to confirm his / her age based on the membership code. Therefore, the customer can recognize that even if the product to be transacted is an age-verification product, by having the membership code read, age verification by a store clerk is not necessary. In this way, the transaction support system S can increase the convenience of customers in registering products by eliminating the need for a store clerk to verify their age. In addition, because the transaction support system S can eliminate the need for a store clerk to verify their age, it can reduce the workload of the store clerk in registering products.

[0185] FIG. 14 is a diagram showing a display example of the self-service POS terminal 4 according to the embodiment. Fig. 14 is a diagram showing a product registration image Imd displayed on the display device 47. The product registration image Imd shows an image transitioned from the product registration image Imc shown in Fig. 13 based on an operation of having the self-service POS terminal 4 read the code symbol. The product registration image Imd includes a notification display area Ard and a checkout button Ba.

[0186] The notification display area Ard is an area showing a notification based on a membership code. In the example of FIG. 14, it is assumed that the self-service POS terminal 4 has determined that the member's age has been set based on the membership code. The notification display area Ard includes a message showing "age confirmed." Based on the determination that the member's age has been set, the display device 47 temporarily displays the message showing "age confirmed" in the notification display area Ard by displaying a pop-up or the like.

[0187] According to this example, the processing circuit 40 can notify the customer of the result of age verification based on the membership code. Therefore, the customer can recognize that age verification has been performed based on the membership code. In addition, the customer can recognize that age verification by a store clerk is not required even if the product to be traded is an age verification product. In this way, the transaction support system S can increase the convenience of customers in registering products by eliminating the need for a store clerk to verify the age.

[0188] FIG. 15 is a diagram showing a display example of the self-service POS terminal 4 according to the embodiment.

In the example of FIG. 15, it is assumed that the self-service POS terminal 4 has determined that the member's age has been set based on the membership code. The notification display area Are includes a message indicating "age verified." The display device 47 may display the message indicating "age verified" temporarily, or may display it until product registration is completed. Note that the display device 47 does not have to display the message indicating "age verified."

[0190] According to this example, the processing circuit 40 can notify the customer of the result of age verification based on the membership code on the product registration screen. Therefore, the customer can recognize that age verification by a store clerk is not required even if the product to be traded is an age verification product. In this way, the transaction support system S can increase the convenience of customers in product registration by eliminating the need for a store clerk to verify the age.

[0191] FIG. 16 is a diagram showing a display example of the self-service POS terminal 4 according to the embodiment. 16 is a diagram showing a payment processing image Imf displayed on the display device 47. The payment processing image Imf shows an image transitioned from the product registration image based on the operation of the checkout button Ba in the product registration image.

[0192] The notification display area Arf is an area showing a notification based on a membership code. In the example of FIG. 16, it is assumed that the self-service POS terminal 4 has determined that the member's age has been set based on the membership code. The notification display area Arf includes a message showing "age confirmed." The display device 47 may temporarily display the message showing "age confirmed" by displaying a pop-up or the like.

[0193] According to this example, the processing circuit 40 can notify the customer of the result of age verification based on the membership code before the payment process. Therefore, the customer can recognize that age verification by a store clerk is not required even if the product to be traded is an age verification product. In this way, the transaction support system S can increase the convenience of customers in registering products by eliminating the need for a store clerk to verify the age.

[0194] FIG. 17 is a diagram showing a display example of the store terminal 5 according to the embodiment. 17 is a diagram showing a monitoring image Img displayed on the display device 57. The monitoring image Img shows a monitoring image when it is determined that the age of the member is set based on the membership code in the self-service POS terminal 4. The monitoring image Img includes a notification display area Arg and a purchase restriction display area Arh.

[0195] The notification display area Arg is an area that shows a notification based on a membership code. In the example of FIG. 17, it is assumed that the store terminal 5 has acquired information regarding a notification that shows that the member's age has been set. The notification display area Arg includes a message indicating "age confirmed." The display device 57 may temporarily display the message indicating "age confirmed" by displaying a pop-up or the like.

[0196] The purchase restriction display area Arh is an area indicating that a product that is restricted from purchase, such as an age verification product, has been registered. In the example of Fig. 17, the purchase restriction display area Arh indicates a message indicating that an age verification product has been registered.

[0197] According to this example, the processing circuit 40 can notify the store terminal 5 of the result of age verification of the customer based on the membership code. Therefore, the user of the store terminal 5 can recognize that age verification is not required even if the product to be traded is an age verification product. This allows the transaction support system S to reduce the workload of store clerks in registering products.

[0198] (Modification) A variation of the above description will now be described.

[0199] In the above description, an example in which an age identification code is set as the option code has been described, but the present invention is not limited to this. The option code may include a code related to a place of residence instead of or in addition to the age identification code. The code related to a place of residence is also called a place of residence identification code. The place of residence identification code is data indicating information related to a place of residence of a member. The information related to a place of residence of a member is, for example, a condition related to a place of residence of a member. The condition related to a place of residence of a member includes information for identifying a place of residence of a member. The condition related to a place of residence of a member includes, for example, a condition under which a privilege applicable according to a place of residence can be applied. A privilege is a beneficial event given to a customer. For example, a privilege includes discount information for a transaction. The privilege applicable according to a place of residence includes, for example, a privilege provided by a local government, such as a childcare support coupon, a tourism coupon, etc. The place of residence identification code is, for example, a code indicating residence in a specific area or a place of residence. The specific area includes a specific prefecture, a specific city, town, or village, etc. The place of residence identification code may indicate one or more conditions related to a place of residence.

[0200] If the option code includes a code related to a place of residence instead of an age identification code, the above-described embodiment can be applied by replacing "age" with "place of residence." The above-described embodiment can be applied by replacing "age verification product" with "benefit application product." A benefit application product refers to a product to which a benefit that is applicable depending on a place of residence is applied. If the option code includes a code related to a place of residence in addition to the age identification code, the above-mentioned embodiment can be applied by adding a process in which "age" is read as "place of residence" in addition to the process of the age identification code. Regarding the process in which "age" is read as "place of residence", the above-mentioned embodiment can be applied by reading "age verification product" as "benefit applicable product".

[0201] According to this example, the POS terminal 3 or the self-service POS terminal 4 can confirm the address of the user of the user terminal 2 based on the membership code. Therefore, the POS terminal 3 or the self-service POS terminal 4 does not display a message indicating that address confirmation is necessary even if the product to be transacted is a special offer product. The store clerk does not need to confirm the member's address. The POS terminal 3 or the self-service POS terminal 4 can apply a special offer based on the address information, based on the membership code. This allows the transaction support system S to reduce the workload of the store clerk in registering products.

[0202] In the above description, the membership code including an ID code for identifying a member of the electronic receipt service has been used as an example, but is not limited to this. The membership code may include ID codes for identifying members of various services. The various services include, for example, services for each store, services for each business operator, services for each business group, etc.

[0203] In the above embodiment, when the user terminal 2 holds the user's attribute data, the option code may be automatically updated. For example, a case will be described where the option code is an age identification code and the user terminal 2 holds the user's date of birth. When the user's age changes from less than a certain age to more than the certain age, the user terminal 2 may update the age identification code from a code indicating "less than a certain age" to a code indicating "more than a certain age". According to this example, the user of the user terminal 2 does not need to re-register the attribute data even if there is a change in the attribute data. Therefore, the transaction support system S can increase the convenience of the customer.

[0204] In the above embodiment, when the server 1 holds the attribute data of the user, the option code may be automatically updated. For example, a case will be described where the option code is an age identification code and the server 1 holds the user's date of birth. When the user's age changes from under a certain age to over a certain age, the server 1 may update the age identification code from a code indicating "under a certain age" to a code indicating "over a certain age". According to this example, the user of the user terminal 2 does not need to re-register the attribute data even if there is a change in the attribute data. Therefore, the transaction support system S can increase the convenience of the customer.
