(3) Merchandise purchase processing
Next, an overview of product purchase processing by the management system 100 will be described. Product purchase processing is processing in which a customer purchases a product using the mobile terminal 3 at the store 8 . FIG. 7 is a flowchart showing an outline of product purchase processing. The product purchase process is roughly divided into a store entry process S100, a product selection process S200, and a checkout process S300. The product purchase process is mainly realized by the management server 2, the mobile terminal 3 and the accounting machine 5 executing programs prepared in advance.

(3-1) Store entry processing First, store entry processing will be described. The store entry process is a process that is performed prior to product purchase when a customer enters the store 8, and corresponds to preparation for product purchase. FIG. 8 is a flow chart showing an example of the store entry process. This processing is performed by the mobile terminal 3 and the management server 2 .

First, when the customer enters the store 8, the customer uses the portable terminal 3 to read the store bar code (step S101). The shop barcode is pasted on a predetermined place in the shop 8, for example, on a wall near the entrance of the shop or on a card used for shopping. When the customer reads the store barcode, the portable terminal 3 acquires the store ID from the read store barcode and transmits it to the management server (step S102). When transmitting the store ID, the mobile terminal 3 also transmits customer identification information for identifying the customer who uses the mobile terminal 3 or the mobile terminal 3 . It should be noted that, even in the product selection process and accounting process described below, basically when the portable terminal 3 transmits some information to the management server 2, it also transmits customer identification information for identifying itself.

The management server 2 receives the store ID from the mobile terminal 3 and acquires the sales price list of the store from the product information DB 28 (step S104). This is because the selling price of the product differs from store to store. Then, the management server 2 transmits store information including the store name and sale information of the store to the mobile terminal 3 (step S105), and the mobile terminal 3 receives the store information (step S106). As a result, the current store name and sale information of the store are displayed on the display unit 31 of the portable terminal 3, and the customer can start shopping. The store information transmitted by the management server 2 includes information indicating the customer's transaction status at the store, and when the customer starts shopping at the store, the transaction status is new. On the other hand, if the customer stops shopping at the store for some reason, the purchase product list screen corresponding to the transaction status up to that point is displayed on the portable terminal 3 .

(3-2) Product Selection Processing Next, product selection processing will be described. The product selection process is a process in which the customer uses the portable terminal 3 to read the product barcode attached to the product and registers the product in the purchase product list. FIG. 9 is a flowchart of product selection processing. This processing is executed by the mobile terminal 3 and the management server 2 .

First, when the customer finds a product that the customer wants to purchase, the customer sets the mobile terminal 3 to the product reading mode, and reads the product barcode attached to the product with the mobile terminal 3 (step S201: Yes). The portable terminal 3 transmits the product identification information of the read product to the management server 2 (step S202). At this time, the product quantity is automatically set to "1". When the management server 2 receives the product identification information from the mobile terminal 3 (step S203), it updates the purchase product list and transmits it to the mobile terminal 3 (step S204). The portable terminal 3 receives the updated purchase product list and displays it on the display unit 31 (step S205). As a result, the newly added product and its quantity are added to the purchase product list and displayed on the portable terminal 3. - 特許庁

Next, when the customer operates the mobile terminal 3 to change the product quantity as necessary, the mobile terminal 3 acquires the changed quantity (step S206: Yes). When the product bar code is read for the first time, the quantity of the product is automatically set to "1". can be changed. When the quantity after change is set, the portable terminal 3 transmits the product identification information of the product to be changed and the quantity after change to the management server 2 (step S207).

When the management server 2 receives the product identification information and the changed quantity from the mobile terminal 3 (step S208), it updates the purchase product list and transmits it to the mobile terminal 3 (step S209). The portable terminal 3 receives the updated purchase product list and displays it on the display unit 31 (step S210). As a result, the quantity change is reflected in the purchase product list.

Next, the mobile terminal 3 determines whether or not the customer has pressed the payment button (step S211). The payment button is a button that the customer presses when finishing shopping. If the payment button has not been pressed (step S211: No), the process returns to step S201. Thus, the customer can add items, change quantities, and continue shopping until the payment button is pressed. When the payment button is pressed (step S211: Yes), the product selection process ends.

FIG. 10 shows a display example of a purchase product list screen displayed on the mobile terminal 3. As shown in FIG. In this example, the purchased product list screen includes a read product button 90, a list display field 91, a subtotal display field 92, a total amount display field 93, a home screen transition button 94, a payment button 95, and a transaction stop button. 96.

When the mobile terminal 3 detects that the read product button 90 has been selected by a tap operation or the like, the mobile terminal 3 switches the display of the display unit 31 to the read product screen. On the product reading screen, the portable terminal 3 displays an image or the like obtained from the activated reading unit 36 . As a result, the customer can read the product barcode 7 by moving the product or the portable terminal 3 so that the product barcode 7 is positioned within the reading range of the reading unit 36 .

The list display field 91 displays the name, quantity, and price of each purchased product. Also, a quantity decrease button 97 and a quantity increase button 98 are displayed for each purchased item in the list display field 91 . When the mobile terminal 3 receives a change in the quantity of the purchased product by pressing the quantity decrease button 97 or the quantity increase button 98, for example, the product identification information of the purchased product whose quantity has been changed and the changed quantity are sent to the management server 2. Send to

The subtotal display field 92 displays a subtotal of sales prices excluding tax for all products in the purchased product list, and the total display field 93 displays the total sales price including tax for all products in the purchased product list. The management server 2 calculates these subtotals or total amounts based on the prices of purchased products registered in the product information DB 28, specifically, based on the sales price list of the store acquired by the store entry process.

When detecting that the home screen transition button 94 has been selected, the mobile terminal 3 transmits a home screen display request to the management server 2, and displays a predetermined home screen based on the display information received as a response. The home screen may display information on discounts and discounts at the store 8, registered information of the customer of the portable terminal 3, and the like.

When the mobile terminal 3 detects that the payment button 95 has been selected, the mobile terminal 3 transmits an accounting request to the management server 2, and displays a payment screen including an accounting bar code screen, which will be described later, based on display information received as a response. do. Further, when detecting that the transaction abort button 96 has been selected, the mobile terminal 3 transmits information for notifying the transaction abort to the management server 2 . In this case, the management server 2 deletes the purchase product list corresponding to the mobile terminal 3 .

(3-3) Accounting processing Next, accounting processing will be explained. The accounting process is the process of paying for the product selected by the customer through the product selection process. FIG. 11 is a flowchart of accounting processing. This processing is executed by the mobile terminal 3, the management server 2, and the accounting machine 5. FIG.

First, when the payment button 95 described above is pressed, the mobile terminal 3 transmits an accounting request to the management server 2 (step S301). When the management server 2 receives the accounting request (step S302), it calculates the payment amount based on the purchased product list at that time (step S303). Furthermore, the management server 2 generates an accounting barcode (step S304). The accounting barcode is information that uniquely identifies the purchase indicated by the current purchase product list. In one example, the checkout barcode may be a random code or the like that is uniquely associated with the current purchase. In this case, the accounting barcode has a meaning as a payment information inquiry number. The management server 2 transmits a payment screen including the payment amount calculated in step S303 and the accounting barcode generated in step S304 to the mobile terminal 3 (step S305).

The mobile terminal 3 displays the received payment screen on the display unit 31 . FIG. 12 is a display example of a payment screen. In this example, the payment screen includes an accounting barcode 37, a total amount field 38, and a Done button 39. The customer moves to the checkout machine 5 with the portable terminal 3 on which the payment screen is displayed, and reads the checkout bar code with the bar code reader 56 (step S307). The checkout machine 5 displays a payment method selection screen based on the read checkout bar code (step S308). Specifically, the accounting machine 5 transmits the inquiry number indicated by the accounting barcode to the management server 2 and acquires the payment information. The payment information includes details such as the total amount and the IDs and quantities of all the products included in the purchase product list. The accounting machine 5 displays a payment method selection screen based on the acquired payment information.

FIG. 13A shows a display example of the payment method selection screen. The payment method selection screen includes a total amount column 61 , a cash button 62 and a credit button 63 . The customer checks the payment amount by looking at the payment method selection screen, and presses either the cash button 62 or the credit button 63 to make the payment. As a result, the purchase price is settled (step S309). Specifically, when the customer chooses to pay in cash, the accounting machine 5 prompts the customer to insert cash into the cash slot, and when the cash is inserted, the customer pays change as required. If the customer chooses to pay by credit card, the accounting machine 5 prompts the customer to insert the card and, if necessary, prompts the input of the personal identification number, etc., and performs the credit settlement.

When the payment is completed, the checkout machine 5 displays a checkout end screen. FIG. 13B shows a display example of the accounting end screen. In this example, the accounting end screen includes a payment information column 64 , a receipt button 65 and an end button 66 . FIG. 13B shows an example in which the customer selects credit card payment, and the payment information column 64 displays information such as the payment amount and payment method. The receipt button 65 is a button for printing out a receipt. The end button 66 is a button for confirming that the customer has completed the accounting process. When the customer presses the end button 66, the accounting machine 5 reports to the management server 2 that the payment has been completed, and returns the display on the display section 51 to the main menu. A completion button 39 is also displayed on the payment screen shown in FIG. 12, and the customer presses the completion button 39 on the payment screen when the accounting processing is completed. When the completion button 39 is pressed, the portable terminal 3 reports to the management server 2 that the payment has been completed, and returns the display section 31 to the main menu.

In the above example, the accounting bar code is simply an inquiry number for payment information, and accounting machine 5 obtains payment information from management server 2 using this inquiry number. Alternatively, the accounting barcode may contain the payment information. That is, the management server 2 generates an accounting bar code based on the contents of the purchased product list at that time, using information on the total amount and details of the purchased products. In this case, the accounting machine 5 can acquire the payment information by reading and decoding the accounting bar code, so there is no need to communicate with the management server 2 to acquire the payment information. That is, the accounting machine 5 may extract the total amount from the read accounting bar code and display the payment method selection screen.

(4) Unsettled processing
Next, unsettled processing, which is processing performed by the management server 2 when an abnormality occurs when there is an unsettled purchased product list, will be described.

(4-1) Overview
When the management server 2 detects the end of the exclusive application of the mobile terminal 3 used by the customer in which the unsettled purchased merchandise list exists, the management server 2 holds the purchased merchandise list without erasing it from the purchased merchandise list DB 29.例文帳に追加Then, when the management server 2 detects that the dedicated application has been restarted on the target mobile terminal 3, the management server 2 transmits to the mobile terminal 3 the information of the held unsettled purchased product list, so that the management server 2 immediately before the termination of the dedicated application can be performed. The purchase product list is displayed on the portable terminal 3. By doing so, even if the dedicated application is terminated for some reason during shopping, the management server 2 can allow the customer to smoothly resume shopping by restarting the dedicated application.

In addition, when the dedicated application is terminated in a state in which an unsettled purchased product list exists, the management server 2 notifies the existence of the unsettled purchased product list at predetermined time intervals until the dedicated application is restarted. is output to the mobile terminal 3. As a result, the management server 2 can notify the customer of the existence of the unsettled purchase item list, and favorably prompt the customer to resume shopping and make the settlement.

In addition, the management server 2 detects that the unsettled purchased product list is not updated for a predetermined time or longer, or that the portable terminal 3 has left the store 8 while the unsettled purchased product list exists. , causes the mobile terminal 3 to output a notification regarding the list of purchased products for which payment has not been made. In this way, the management server 2 can output a notification to the portable terminal 3 when detecting an abnormal state in unsettled.

(4-2) Processing Flow FIG. 14 is an example of a flow chart showing the procedure of unsettled processing executed by the management server 2 . For example, the management server 2 executes the processing of the flowchart shown in FIG. 14 for each customer who has not completed payment after executing the store entry processing shown in FIG. For convenience of explanation, the unsettled processing shown in FIG. 14 includes the processing executed by the management server 2 in the product selection processing shown in FIG.

First, the mobile terminal 3 used by the customer activates the dedicated application of the mobile terminal 3 to establish communication with the management server 2, and then performs the processing of the flow chart of the entering processing shown in FIG. Then, when the customer finds the product he or she wants to purchase, the customer puts the portable terminal 3 into a product reading mode, and reads the product bar code attached to the product with the portable terminal 3 . The mobile terminal 3 transmits the product identification information of the read product to the management server 2 .

Then, the management server 2 determines whether or not the product identification information has been received from the mobile terminal 3 (step S401). Then, when the management server 2 receives the product identification information from the mobile terminal 3 (step S401; Yes), it updates the purchased product list and transmits the updated purchased product list to the mobile terminal 3 (step S402). Here, if the purchased product list for the target customer is not registered in the purchased product list DB 29, the management server 2 stores the purchased product list whose elements are the received product identification information as the customer identification information of the target customer. is registered in the purchase product list DB 29 in association with. If the management server 2 receives information about the quantity to be changed together with the product identification information from the mobile terminal 3 in step S401, it changes the product quantity indicated by the designated product identification information in step S402. The processing of step S401 corresponds to the processing of steps S203 and S208 of the product selection processing shown in FIG. 9, and the processing of step S402 corresponds to the processing of steps S204 and S209.

Next, the management server 2 determines whether or not the dedicated application of the mobile terminal 3 has ended (step S403). For example, when the communication connection established with the dedicated application of the mobile terminal 3 is disconnected, the management server 2 determines that the dedicated application has ended. In another example, the management server 2 determines that the dedicated application has ended when information transmitted from the mobile terminal 3 is no longer received while the dedicated application is running. It should be noted that the termination of the dedicated application is, for example, in addition to the termination due to the customer's operation on the mobile terminal 3, the interruption of another application on the mobile terminal 3 (for example, incoming call) or the freezing of the dedicated application This includes cases such as forced termination. An example of the termination of the dedicated application due to the customer's operation on the mobile terminal 3 is, for example, when the dedicated application is terminated due to an erroneous operation, the shopping basket is temporarily moved to the service counter of the store 8 due to urgent business. In some cases, the customer leaves the store 8 after leaving the dedicated application temporarily.

Then, when the management server 2 determines that the dedicated application of the mobile terminal 3 has ended (step S403; Yes), it continues to hold the purchase product list of the target customer for which payment has not yet been made (step S404). Specifically, the management server 2 continues to store the target customer's purchased product list in the purchased product list DB 29 without deleting it from the purchased product list DB 29 . In this case, for example, the management server 2 may add flag information or the like indicating that the dedicated application has ended to the purchase product list of the target customer.

Then, the management server 2 causes the mobile terminal 3 to output notifications at predetermined time intervals until the dedicated application of the mobile terminal 3 used by the target customer is restarted (step S405). The predetermined time interval described above is, for example, a predetermined time interval and is stored in the storage unit 23 or the like. In step S405, for example, the management server 2 transmits notification information to the mobile terminal 3 indicating that there is a list of purchased products for which payment has not been made, and displays the notification information on the screen of the mobile terminal 3 using the push notification function. display. As a result, the management server 2 can continuously make the customer using the portable terminal 3 aware of the existence of the purchase item list for which payment has not yet been made.

Then, the management server 2 determines whether or not the dedicated application of the mobile terminal 3 used by the target customer has been restarted (step S406). For example, when the management server 2 re-establishes communication with the dedicated application of the mobile terminal 3 used by the target customer, or receives predetermined information transmitted when the dedicated application is in operation, the target customer It is determined that the dedicated application of the mobile terminal 3 has been restarted. Then, if the dedicated application of the mobile terminal 3 has not been restarted (step S406; No), the management server 2 continues the processing of steps S404 and S405.

On the other hand, when the management server 2 detects that the dedicated application of the mobile terminal 3 used by the target customer has been restarted (step S406; Yes), the management server 2 sends the purchase product list corresponding to the target customer It is transmitted to the terminal 3 (step S407). In this case, the management server 2 extracts the purchased product list linked to the customer identification information of the target customer from the purchased product list DB 29 and transmits the information of the purchased product list to the target mobile terminal 3 . In this case, the portable terminal 3 displays the purchased product list screen on the dedicated application based on the purchased product list information received from the management server 2 . As a result, even if the dedicated application is terminated for some reason during shopping, the customer can continue shopping in the state immediately before the termination of the dedicated application by restarting the dedicated application. That is, in this case, the customer does not need to read the product bar code of the product placed in the shopping cart again before the dedicated application is terminated.

After detecting the restart of the dedicated application, the management server 2 may allow the customer of the mobile terminal 3 to select whether or not to continue shopping using the purchased product list immediately before the termination of the dedicated application. In this case, the management server 2 transmits the purchased product list in step S407 when the customer selects to continue shopping using the purchased product list immediately before the end of the dedicated application. A specific example of this will be described later with reference to FIG.

On the other hand, if it is determined that the dedicated application of the mobile terminal 3 has not ended (step S403; No), the management server 2 determines whether or not a predetermined period of time or more has elapsed since the last update of the purchase product list (step S408). ). That is, the management server 2 determines whether or not the processing of step S402 has been performed within a predetermined time. The above-mentioned predetermined time is determined in advance, for example, in consideration of the average time interval at which products are placed in the product basket in shopping.

Then, if a predetermined period of time or more has passed since the previous purchase product list was updated (step S408; Yes), the management server 2 causes the portable terminal 3 to output a notification to the effect that there is an unsettled purchase product list. (Step S409). As a result, the management server 2 appropriately notifies the customer of the existence of the purchase product list left unsettled and prompts the customer to complete the settlement.

On the other hand, if the predetermined time or more has not passed since the previous purchase product list was updated (step S408; No), the management server 2 determines whether or not the portable terminal 3 has left the store 8 (step S410). In this case, for example, the management server 2 acquires location information transmitted from the mobile terminal 3 and determines whether or not the location indicated by the location information is within the area of the store 8 . The position information described above may be position information based on GPS radio waves, position information based on radio waves of a beacon terminal, or position information based on radio waves of a wireless LAN. Note that the location information indicating the area of the store 8 is stored in the storage unit 23 in advance, for example.

When the management server 2 determines that the mobile terminal 3 has left the store 8 (step S410; Yes), the management server 2 outputs to the mobile terminal 3 a notification that there is a list of purchased products for which payment has not been made. (step S409). As a result, the management server 2 can favorably prompt the customer to complete the payment for the unsettled purchase product list.

In this case, the management server 2 may transmit information to the terminal used by the shop clerk at the store 8 to notify that the customer who has a list of purchased products for which payment has not yet been made has left the store 8. . In other words, the management server 2 may notify the terminal used by the shop clerk of the store 8 of the presence of the mobile terminal 3 that has left the store 8 . In this case, the management server 2 may include the member information recorded in the record of the member information DB 47 corresponding to the target customer in the information transmitted to the terminal used by the store clerk. As a result, the management server 2 can suitably notify the store clerk or the like of the presence of the customer who has left the store 8 without making a payment.

On the other hand, if the management server 2 determines that the mobile terminal 3 is not outside the store 8 (step S410; No), or after step S407 is executed, the management server 2 determines that the target customer has finished shopping. It is determined whether or not (step S411). In this case, the management server 2 determines that the shopping is finished when it detects that the payment for the purchase product list is completed or when it detects that the transaction is canceled in the dedicated application. Then, when the shopping is completed (step S411; Yes), the management server 2 ends the processing of the flowchart. On the other hand, if the shopping has not ended (step S411; No), the management server 2 returns the processing to step S401.

(4-3) Screen Example FIG. 15 is an example of a display screen displayed on the mobile terminal 3 of the target customer by the management server 2 in step S405 of FIG.

In this case, in step S403 of FIG. 14, the predetermined time interval has passed since the dedicated application was terminated, and the dedicated application has not been restarted. , the mobile terminal 3 is caused to output a notification. In this case, based on the information received from the management server 2, the mobile terminal 3 pops up a window 71 displaying "there is a list of unsettled purchased products".

In this way, when the dedicated application of the mobile terminal 3 used by the customer with the unsettled purchased product list is terminated, the management server 2 pops up the window 71 indicating that there is the unsettled purchased product list. indicate. As a result, the mobile terminal 3 can favorably prompt the user to restart the dedicated application and to resume shopping at the store 8 .

FIG. 16 is an example of a display screen displayed by the mobile terminal 3 after restarting the dedicated application from the state shown in FIG.

In this case, the mobile terminal 3 pops up a window 72 on the display screen of the dedicated application of the mobile terminal 3 after restarting the dedicated application. The mobile terminal 3 displays a first button 73 and a second button 74 on the window 72 along with text information indicating that there is a list of unsettled purchased products. The first button 73 is a button for specifying to continue shopping using the unsettled purchase product list, and the second button 74 is a button for specifying to cancel the transaction. Then, when the mobile terminal 3 detects that the first button 73 has been selected, the unsettled purchased product list (that is, the list of purchased products immediately before the end of the dedicated application) transmitted from the management server 2 in accordance with step S407 in FIG. Product list) information is received, and the purchased product list screen is displayed again. In this case, the purchase product list screen displays the purchase product list immediately before the dedicated application ends. On the other hand, when detecting that the second button 74 has been selected, the mobile terminal 3 transmits information notifying of the suspension of the transaction to the management server 2, as in the case where the suspension transaction button 46 is selected on the purchased product list screen. do. In this case, the management server 2 deletes the purchase product list corresponding to the mobile terminal 3 .

FIG. 17 is an example of a display screen displayed on the mobile terminal 3 of the target customer by the management server 2 in step S409 of FIG.

In this case, the management server 2 detects that the predetermined time has passed without the list of unsettled purchased products being updated, or that the mobile terminal 3 has left the store 8 while there is a list of unsettled purchased products. is detected, and a window 75 representing the notification is displayed on the purchase product list screen displayed by the dedicated application. Here, the management server 2 displays on the window 75 the text information prompting the payment of the purchased product list.

(4-4) Utilization of Purchase History The management server 2 may preferably use the information of the purchased product list for which payment has been completed in the purchase of products based on electronic commerce by the same customer. In this case, when the payment is completed, the management server 2 generates purchase history information in which a list of purchased products for which payment has been completed, customer identification information indicating the customer who purchased the product, and information related to payment are associated with each other. is stored in the purchase history DB 49. Then, the management server 2 generates a display and a list of products to be purchased based on the purchase history information stored in the purchase history DB 49 in shopping based on electronic commerce by the same customer.

FIG. 18 is an example of a display screen displayed by the mobile terminal 3 when performing electronic commerce using a dedicated application.

In FIG. 18 , first, the management server 2 detects that the user has input an order based on the past purchase history on the portable terminal 3 . In other words, the management server 2 receives a shopping request from the mobile terminal 3 based on the past purchase history in electronic commerce. Then, when the management server 2 receives the above-described shopping request, the management server 2 extracts from the purchase history DB 49 purchase history information indicating a plurality of purchase records associated with the customer identification information of the customer using the mobile terminal 3. do. Then, the management server 2 generates a purchase history list 76 based on the purchase history information extracted from the purchase history DB 49 and causes the portable terminal 3 to display the generated purchase history list 76 . Here, the purchase history list 76 has a plurality of elements corresponding to past purchase results, and each element includes information on date and time of purchase, store of purchase, settlement number, and total amount. Each element constituting the purchase history list 76 is provided with detail display buttons 77A to 77D (77) for displaying detailed purchase histories.

Then, the customer using the portable terminal 3 refers to the purchase history list 76 and selects the detailed display button 77 corresponding to the purchase history to be referred to in the current electronic commerce. In this case, the management server 2 receives information about the selected detail display button 77 from the mobile terminal 3 and causes the mobile terminal 3 to display a purchase history detail screen corresponding to the selected detail display button 77 . On the detailed screen described above, for example, a purchased product list, which is a list of purchased products, is displayed. Also, the management server 2 preferably generates a shopping list for the current electronic commerce (that is, a list of products to be purchased) based on the purchase product list displayed on the detailed screen. That is, when the management server 2 detects an operation to reflect the purchased product list to the current shopping list on the detailed screen, the management server 2 updates the current shopping list based on the purchased product list indicated by the selected purchase history. Generate. As a result, the customer can preferably purchase a product based on electronic commerce using the past purchase history at the physical store. The terminal used by the customer for electronic commerce is not limited to the mobile terminal 3, and may be any terminal such as a stationary computer used by the customer.
