[Product purchase process]
Next, the outline of the product purchase process by the purchase management system 100 will be described. The product purchase process is a process in which a customer purchases a product at a store 8 using a mobile terminal 3. FIG. 6 is a flowchart showing an outline of the product purchase process. The product purchase process is roughly classified into a store entry process S100, a product selection process S200, and an accounting 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.

(Store entry process)
First, the store entry process will be described. The store entry process is a process performed prior to the purchase of a product when a customer enters the store 8, and corresponds to preparation for the purchase of the product. FIG. 7 is a flowchart showing an example of the store entry process. This process is performed by the mobile terminal 3 and the management server 2.

First, when the customer enters the store 8, the customer reads the store barcode using the mobile terminal 3 (step S101). The store barcode is affixed to a predetermined place in the store 8, for example, a wall near the entrance of the store, a card used for shopping, or the like. When the customer reads the store barcode, the mobile 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 the customer identification information that identifies the customer who uses the mobile terminal 3 or the mobile terminal 3. In the product selection process and the accounting process described below, the mobile terminal 3 basically transmits the customer identification information for identifying itself when transmitting some information to the management server 2.

The management server 2 receives the store ID from the mobile terminal 3 and acquires the selling price list of the store from the product information DB 28 (step S104). This is because the selling price of the product is different for each store. Then, the management server 2 transmits the store information including the store name and the 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, sale information of the store, and the like are displayed on the display unit 31 of the mobile terminal 3, and the customer can start shopping. The store information transmitted by the management server 2 includes information indicating the transaction status of the customer at the store, and when a new shopping is started at the store, the transaction status becomes new. On the other hand, when the customer interrupts shopping at the store for some reason, the purchased product list screen corresponding to the transaction state up to that point is displayed on the mobile terminal 3.

(Product selection process)
Next, the product selection process will be described. The product selection process is a process in which the customer uses the mobile terminal 3 to read the product barcode 7 attached to the product and registers it in the purchased product list. FIG. 8 is a flowchart of the product selection process. This process is executed by the mobile terminal 3 and the management server 2.

First, when the customer finds a product he / she wants to purchase, he / she puts the mobile terminal 3 into the product reading mode and reads the product barcode 7 attached to the product by the mobile terminal 3 (step S201: Yes). The mobile terminal 3 transmits the read product identification information of the product to the management server 2 (step S203). At this time, the quantity of the product is automatically set to "1". When the management server 2 receives the product identification information from the mobile terminal 3 (step S203), the management server 2 updates the purchased product list and transmits it to the mobile terminal 3 (step S204). The mobile terminal 3 receives the updated 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 purchased product list and displayed on the mobile terminal 3 as the purchased product list screen.

Next, when the customer operates the mobile terminal 3 to change the quantity of the product as needed, the mobile terminal 3 acquires the changed quantity (step S206: Yes). When the product barcode is first read, the quantity of the product is automatically set to "1", but when the customer purchases the same product more than once, the mobile terminal 3 is operated to set the quantity. Can be changed. When the changed quantity is set, the mobile terminal 3 transmits the product identification information of the product to be changed and the changed quantity 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), the management server 2 updates the purchased product list and transmits it to the mobile terminal 3 (step S209). The mobile terminal 3 receives the updated purchased product list and displays it on the display unit 31 as a purchased product list screen (step S210). As a result, the quantity change is reflected in the purchased product list.

Next, the mobile terminal 3 determines whether or not the payment button 45 has been pressed by the customer (step S211). The payment button 45 is a button that the customer presses when completing the shopping. If the payment button 45 is not pressed (step S211: No), the process returns to step 201. In this way, the customer can add products, change the quantity, and continue shopping until the payment button 45 is pressed. Then, when the payment button 45 is pressed (step S211: Yes), the product selection process ends.

FIG. 9 shows a display example of the purchased product list screen displayed on the mobile terminal 3. In this example, the purchased product list screen has a product reading button 40, a list display field 41, a subtotal display field 42, a total amount display field 43, a home screen transition button 44, a payment button 45, and a transaction cancellation button. It has 46 and.

When the mobile terminal 3 detects that the product reading button 40 has been selected by a tap operation or the like, the mobile terminal 3 switches the display of the display unit 31 to the product reading screen. On the product reading screen, the mobile terminal 3 displays an image or the like acquired from the activated reading unit 36. As a result, the customer can move the product or the mobile terminal 3 so that the product barcode 7 is located within the reading range of the reading unit 36, and can read the product barcode 7.

In the list display column 41, the name, quantity, and price of the purchased product are displayed for each purchased product. Further, a quantity decrease button 47 and a quantity increase button 48 are displayed for each purchased product in the list display field 41. Then, when the mobile terminal 3 accepts the quantity change of the purchased product by the quantity decrease button 47 or the quantity increase button 48, the mobile terminal 3 transmits the product identification information of the purchased product whose quantity has been changed and the changed quantity to the management server 2. ..

The subtotal display column 42 displays the subtotal of the selling price excluding tax for all the products in the purchased product list, and the total amount display column 43 displays the total amount of the selling price including tax for all the products in the purchased product list. The management server 2 calculates these subtotals or total amounts based on the prices of the purchased products registered in the product information DB 28, specifically, the selling price list of the store acquired by the store entry process.

When the mobile terminal 3 detects that the home screen transition button 44 is selected, it 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, customer registration information on the mobile terminal 3, and the like.

When the mobile terminal 3 detects that the payment button 45 has been selected, it transmits an accounting request to the management server 2 and displays a payment method selection screen based on the display information received as a response. Further, when the mobile terminal 3 detects that the transaction cancellation button 46 is selected, the mobile terminal 3 transmits information for notifying the transaction cancellation to the management server 2. In this case, the management server 2 deletes the purchased product list corresponding to the mobile terminal 3.

(Accounting)
Next, the accounting process will be described. The accounting process is a process of paying for a product selected by a customer by a product selection process. FIG. 10 is a flowchart of accounting processing. This process is executed by the mobile terminal 3, the management server 2, and the accounting machine 5.

First, when the payment button 45 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), the management server 2 calculates the payment amount based on the purchased product list at that time (step S303). The management server 2 transmits a payment method selection screen including the purchased product list and the payment amount calculated in step S303 to the mobile terminal 3 (step S304).

The mobile terminal 3 displays the received payment method selection screen on the display unit 31 (step S305). FIG. 11 is a display example of the payment method selection screen. In this example, the payment method selection screen includes a list display field 61, a subtotal display field 62, a total amount display field 63, a credit button 64, an electronic money button 65, and a cash button 66. In the list display field 61, the name, quantity, and price of the purchased product are displayed. The subtotal display column 62 displays the subtotal of the selling price excluding tax for all the purchased products displayed in the list display column 61, and the total amount display column 63 displays the total amount of the selling price including tax for all the purchased products. The customer confirms the payment amount by looking at the payment method selection screen, and presses any of the credit button 64, the electronic money button 65, and the cash button 66. The payment method selection screen includes a list display field 61 and a subtotal display field 62, but the present invention is not limited to this, and it is sufficient if the payment amount can be confirmed and the payment method can be selected.

When the credit button 64 or the electronic money button 65 is pressed, that is, when the payment method is not cash (step S306; No), the control unit 35 of the mobile terminal 3 makes a payment according to the selected payment method. (Step S307).

Specifically, when the customer selects payment by credit by pressing the credit button 64, the mobile terminal 3 displays the name of the credit company that makes the credit payment, the credit card number, the payment amount, and the like. Then, when the customer receives a payment request by pressing the payment button or the like, the mobile terminal 3 prompts the input of a personal identification number or the like as necessary to perform credit payment. In addition, the customer can use his / her mobile terminal 3 by registering a credit card with the store operating company when registering as a member, or by registering with a payment agency contracted by the store. You can use it to make credit payments.

When the payment is completed, the mobile terminal 3 displays the accounting end screen (step S308). FIG. 12A shows a display example of the accounting end screen displayed on the display unit 31 when the credit settlement is completed. FIG. 12A is an example when the customer selects credit card payment, and the accounting end screen includes a payment information field 71, a receipt button 72, and an end button 73. The payment information column 71 displays information such as the payment amount and the payment method, for example, the card company name. The receipt button 72 is a button for printing out a receipt. The end button 73 is a button for confirming that the customer has completed the accounting process. When the customer presses the end button 73, the mobile terminal 3 reports to the management server 2 that the payment has been completed, and returns the display of the display unit 31 to the main menu.

When the customer selects payment with electronic money by pressing the electronic money button 65, the mobile terminal 3 displays various electronic money that can be used for payment, the payment amount, and the like. Then, upon receiving the payment request by pressing the payment button of the customer, the mobile terminal 3 prompts the user to select the electronic money to be used for payment from a plurality of electronic money as necessary, and performs the electronic money payment. When the payment is completed, the mobile terminal 3 displays the accounting end screen (step S308). FIG. 12B is an example when the customer selects electronic money payment, and the accounting end screen includes a payment information field 74, a receipt button 75, and an end button 76. The payment information column 74 displays information such as the payment amount, the payment method, for example, the name of the electronic money, and the balance of the electronic money. Since the receipt button 75 and the end button 76 are the same as the receipt button 72 and the end button 73 in FIG. 12 (A), the description thereof will be omitted.

On the other hand, when the cash button 66 is pressed, that is, when the payment method is cash (step S306; Yes), the control unit 35 of the mobile terminal 3 transmits the cash payment request to the management server 2. When the management server 2 receives the cash payment request (step S309), the management server 2 generates an accounting barcode based on the purchased product list at that time (step S310). The accounting barcode is information that uniquely identifies the purchase content indicated by the currently purchased product list. In one example, the accounting barcode can be a random code uniquely associated with the purchase content at that time. In this case, the accounting barcode has a meaning as an inquiry number for payment information. The management server 2 transmits a payment screen including the payment amount calculated in step S303 and the accounting barcode generated in step S310 to the mobile terminal 3 (step S311).

The mobile terminal 3 displays the received payment screen on the display unit 31 (step S312). FIG. 13 is a display example of the payment screen. In this example, the payment screen includes an accounting barcode 67, a total amount field 68, and a completion button 69. The customer moves to the accounting machine 5 with the mobile terminal 3 on which the payment screen is displayed, and reads the accounting barcode with the barcode reader 56 (step S313). The accounting machine 5 displays a cash payment screen based on the read accounting barcode (step S314). Specifically, the accounting machine 5 transmits the inquiry number indicated by the accounting barcode to the management server 2 and acquires payment information from the management server 2. The payment information includes details such as the total amount and the IDs and quantities of all the products in the purchased product list. The accounting machine 5 displays a cash payment screen based on the acquired payment information.

FIG. 14A shows a display example of the cash payment screen. On the cash payment screen, a total amount column 77 and a message prompting cash to be inserted into the cash slot are displayed. When the customer inserts cash into the cash slot, the accounting machine 5 pays change as needed. When the cash settlement is completed (step S315), the accounting machine 5 displays the accounting end screen (step S316). FIG. 14B shows a display example of the accounting end screen. FIG. 14B is an example when the customer selects cash settlement, and the accounting end screen includes a settlement information field 78, a receipt button 79, and an end button 80. The payment information column 78 displays information such as the amount of payment. Since the receipt button 79 and the end button 80 are the same as the receipt button 72 and the end button 73 in FIG. 12 (A), the description thereof will be omitted. When the customer presses the end button 80, the accounting machine 5 reports to the management server 2 that the settlement has been completed, and returns the display of the display unit 51 to the main menu. As shown in FIG. 13, the completion button 69 is also displayed on the payment screen displayed on the mobile terminal 3, and the customer presses the completion button 69 on the payment screen when the accounting process is completed. When the completion button 69 is pressed, the mobile terminal 3 reports to the management server 2 that the payment has been completed, and returns the display unit 31 to the main menu.

In the above example, the accounting barcode is simply an inquiry number for payment information, and the accounting machine 5 uses this inquiry number to acquire payment information from the management server 2. Instead, the accounting barcode may include payment information. That is, when the management server 2 receives the cash payment request, it generates an accounting barcode using the total amount and the information of the purchased product list based on the contents of the purchased product list at that time. In this case, the accounting machine 5 can acquire the payment information by reading and decoding the accounting barcode, so that it is not necessary to communicate with the management server 2 in order to acquire the payment information. That is, the accounting machine 5 may extract the total amount from the read accounting barcode and display the payment method selection screen.

[Check points]
Next, the point confirmation in the purchase management system of the present embodiment will be described. Among the products sold in stores, there are point-limited products such as "up to 3 items per person" that have a limited number of items that can be purchased. As a result, it is possible to prevent one customer from buying up a product at a bargain price and to provide a fair service to all customers. Therefore, when a product purchased by a customer includes a product with a limited number of points, it is necessary to confirm the score. The point confirmation is to confirm that the points of the point-restricted product purchased by the customer are within the points set for the point-restricted product (hereinafter, also referred to as "restricted points"). If the number of customers is not one but with family and friends, the limit points will increase according to the number of customers. For example, in the case of a parent and child, the parent is the main customer and the child is the sub-customer. When the limit score of a certain point-restricted product is "3" per person, the limit score of the point-restricted product is "6" if the main customer has one sub-customer, and the main customer has 2 sub-customers. If you bring people, it will increase in proportion to the number of customers, such as "9" points.

[Product selection process with score confirmation]
In the present embodiment, this score confirmation is carried out by the mobile terminal 3, and purchase control is performed so that only the score-limited products within the limit points can be purchased. Specifically, the point-restricted products can be registered in the purchased product list only within the limited points, and more than the limited points cannot be purchased. It should be noted that the point-restricted product and the limited points are stored in advance in association with the product identification information, and the limited points can be arbitrarily set. FIG. 15 shows a flowchart of a product selection process that involves confirmation of points. This process is executed by the mobile terminal 3 and the management server 2. In the product selection process accompanied by the score confirmation, detailed description of the same process as the product selection process shown in FIG. 8 will be omitted.

First, when the customer finds the product he / she wants to purchase, he / she sets the mobile terminal 3 in the product reading mode and reads the product barcode 7 attached to the product by the mobile terminal 3 (step S501; Yes). The mobile terminal 3 transmits the read product identification information of the product to the management server 2 (step S502). When the management server 2 receives the product identification information from the mobile terminal 3 (step S503), the management server 2 performs a score confirmation process (step S504).

FIG. 16 is a flowchart of the score confirmation process. This process is executed by the mobile terminal 3 and the accounting machine 5. The management server 2 determines whether or not the point-restricted product is included based on the product identification information received from the mobile terminal 3 (step S601). If the point-restricted product is not included (step S601; No), the process proceeds to step S618 and updates the purchased product list based on the product identification information received from the mobile terminal 3 (step S618).

On the other hand, when the point-restricted product is included (step S601; Yes), the management server 2 generates a warning screen and transmits it to the mobile terminal 3. The mobile terminal 3 receives the warning screen from the management server 2 and displays it on the display unit 31 (step S603). FIG. 17 shows a display example of a warning screen. As shown in the figure, the alert screen includes a message to inform the point-restricted products included in the purchased product list and the limited points, a message to the effect that only the limited points can be purchased, and an OK button 81. .. When the OK button is pressed, the mobile terminal 3 makes a request for confirmation of the limited number of points (step S604).

Upon receiving the limited point confirmation request, the management server 2 adds the point limited product to the purchased product list based on the product identification information received from the mobile terminal 3 in step S601 and the purchased product list at that time. If so, it is determined whether or not the score of the score-restricted product is within the limit score (step S605). If the number of points is within the limit (step S605; Yes), the process proceeds to step S618 and updates the purchased product list based on the product identification information received from the mobile terminal 3 (step S618). On the other hand, if the score is not within the limit (step S605; No), the management server 2 generates a score confirmation screen and transmits it to the mobile terminal 3 (step S606).

The mobile terminal 3 receives the score confirmation screen from the management server 2 and displays it on the display unit 31 (step S607). FIG. 18 shows a display example of the score confirmation screen. As shown in the figure, the score confirmation screen includes a message notifying the point-restricted products included in the purchased product list and the limited points, a message prompting the return of the point-restricted products so as to be within the limited points, and OK. A button 82 and a clerk check button 83 are included. The score confirmation screen is an example of the warning screen of the present invention. When the customer agrees to return a part of the point-restricted product and adjust it within the limit point by the message on the point confirmation screen, he presses the OK button 82 and requests the cancellation of the product identification information. On the other hand, if the customer does not agree to adjust the point-restricted product within the limited points, the customer presses the clerk check button 83 to request the clerk check. The mobile terminal 3 determines whether the cancellation request or the clerk check request has been made (step S608). When it is determined that the cancellation request has been made, the mobile terminal 3 transmits the cancellation request to the management server 2. When the management server 2 receives the cancellation request from the mobile terminal 3, the management server cancels the product identification information received from the mobile terminal 3 in step S601 (step S609), and returns to the product selection process (step S610). By returning to the product selection process in this way, the customer can return a part of the point-restricted products and adjust the points within the limited points.

On the other hand, when it is determined that the clerk check request has been made, the mobile terminal 3 transmits the score confirmation request to the management server 2 (step S611). When the management server 2 receives the score confirmation request from the mobile terminal 3 (step S612), the management server 2 generates a call screen and transmits it to the mobile terminal 3 (step S613). The mobile terminal 3 receives the call screen from the management server 2 and displays it on the display unit 31 (step S614). FIG. 19 shows a display example of the call screen. As shown in the figure, the call screen includes a message prompting the clerk to confirm the score, a back button 84, and an execute button 85. When the execution button 85 is pressed by the customer, the mobile terminal 3 displays the reading screen on the display unit 31 (step S615).

FIG. 20 shows a display example of the reading screen. As shown in the figure, the reading screen displays a message prompting the clerk to scan the clerk barcode and a hook bracket 86 indicating the area to be scanned. Specifically, when the customer presses the execution button 85 on the call screen on the mobile terminal 3 to display the reading screen, the customer calls out to the clerk to confirm the score. The clerk confirms the number of points-restricted products that the customer puts in the basket or the like. At this point, since the number of points-restricted products to be purchased is greater than the limited points, the clerk explains to the customer that the points-restricted products can only be purchased within the limited points.

When there is a follow-up customer such as a parent and child, the clerk causes the display unit 31 to pop up a clerk-only screen by inputting, for example, a clerk operation code on the reading screen displayed on the mobile terminal 3. Then, the clerk changes the limited number of points of the point-restricted product that the customer can purchase from the clerk-only screen according to the number of sub-customers, and sets a new one. At this time, the limit number to be changed may be input by the clerk, or may be automatically set by the clerk inputting the number of sub-customers. Then, the clerk determines that there is no problem if the number of points is within the newly set limit, and presents the clerk barcode printed on his / her clerk card to the customer. The customer scans the store clerk barcode on the reading screen displayed on the mobile terminal 3. The clerk barcode is an example of the score confirmation information of the present invention, and if it is information indicating that the clerk has completed the score confirmation, a password, a PIN (Personal Identification Number) code, a QR (Quick Response) code, etc. It may be.

If there is no sub-customer and the number of points-restricted products to be purchased exceeds the limit, the clerk urges the customer to return the points-restricted product within the limit, which is displayed on the mobile terminal 3. By inputting, for example, a clerk operation code on the reading screen, the clerk-only screen is displayed in a pop-up on the display unit 31. Then, the clerk requests the cancellation of the product identification information on the clerk-only screen without scanning the clerk barcode on the reading screen.

The mobile terminal 3 determines whether or not the clerk barcode has been scanned (step S616). If the clerk barcode is not correctly scanned (step S616; No), the mobile terminal 3 proceeds to the process of step S608. As a result, the customer can return to the product selection process, return a part of the point-restricted products, and adjust the points within the limited points. On the other hand, when the clerk barcode is correctly scanned (step S616; Yes), the mobile terminal 3 transmits the scanned clerk barcode to the management server 2 as score confirmation information (step S617). The management server 2 determines that the score confirmation has been completed by acquiring the score confirmation information from the mobile terminal 3, and updates the purchased product list based on the product identification information received from the mobile terminal 3 in step S601 (). Step S618). As a result, the score confirmation process is completed, and the process proceeds to step S505 of the product selection process shown in FIG.

In the above example, the mobile terminal 3 acquires the score confirmation information by scanning the clerk barcode, but instead of this, a new limit score is set on the clerk-only screen or the clerk-only screen. The score confirmation information may be acquired by pressing the completion button of. Further, in the above example, the clerk inputs the clerk operation code to display the clerk-only screen on the display unit 31 of the mobile terminal 3. Here, the clerk operation code is information for displaying and operating the clerk-dedicated screen on the display unit 31 of the mobile terminal 3, and a password, a bar code, or the like owned only by the clerk can be considered.

When the score confirmation process is completed, the mobile terminal 3 performs the processes of steps S505 to S513 of the product selection process shown in FIG. The processing of steps S505 to S509 and the processing of steps S511 to S513 in FIG. 15 are basically the same as the processing of steps S204 to S211 in FIG. 8, and the processing of step S510 is the same as the score confirmation processing of step S504. Therefore, the description thereof will be omitted.

According to this, it is possible to control the purchase so that only the point-limited products within the limit points can be purchased. Therefore, even if the store clerk does not register or settle the product, it is possible to prevent a problem that one customer buys up the product at a bargain price and provide the service fairly to all the customers. ..

In addition, when shopping with multiple people such as families, only one main customer pays the bill, but it is conceivable to purchase up to the limit of the number of subordinate customers who are with the limited number of products. .. Even in such a case, it is possible to appropriately respond to the needs of the customer by changing the limit score according to the number of follow-up customers when checking the score.

[Modification example]
(Modification example 1)
In the above embodiment, the management server 2 immediately updates the purchased product list when it receives the score confirmation information from the mobile terminal 3 in the process of step S618 even when the limit score is changed due to the existence of the sub-customer. I'm supposed to do it. However, the present invention is not limited to this, and when the limit points are changed due to the presence of a sub-customer, the management server 2 receives the new limit points as change information from the mobile terminal, and the customer will purchase. The purchased product list may be updated only when the specified point-restricted product is within the new limit. According to this, even if the clerk does not notice by visually checking the score, it is possible to prevent the customer from fraudulently purchasing a large number of score-restricted products.

(Modification 2)
In the above embodiment, when the limit number is changed due to the presence of a sub-customer and a new setting is made, the clerk-only screen is operated, but the present invention is not limited to this, and the mobile terminal 3 is not limited to this. A new limit point may be set by the number of times the clerk bar code is scanned on the reading screen, and the change information may be transmitted to the management server 2. For example, if the limited number of points of a certain point-restricted product is "2", if the clerk barcode is scanned twice in a row on the reading screen within a certain period of time, the limited number of points will be "4" and the limited number of points will be scanned three times in a row. For example, the limited number of points may be set to "6".
