[Product purchase processing]
Next, an overview of product purchase processing by the purchase management system 100 will be explained. The product purchase process is a process in which a customer purchases a product using the mobile terminal 3 at the store 8. FIG. 6 is a flowchart showing an overview of the product purchase process. The product purchase process can be broadly divided into store entry process S100, product selection process S200, and checkout process S300. Note that the product purchase process is mainly realized by the management server 2, the mobile terminal 3, and the accounting machine 5 each executing a program prepared in advance.

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

First, upon entering the store 8, the customer reads the store barcode using the mobile terminal 3 (step S101). The store barcode is affixed to a predetermined location within the store 8, such as a wall near the entrance of the store or a card used for shopping. 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 2 (step S102). When transmitting the store ID, the mobile terminal 3 also transmits customer identification information for identifying the mobile terminal 3 or the customer using the mobile terminal 3. In addition, also in the product selection process and accounting process described below, when the mobile terminal 3 basically 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 selling price list of the store from the product information DB 28 (step S104). This is because the selling prices of products differ 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, sale information, etc. of the store are displayed on the display section 31 of the mobile terminal 3, and the customer is ready to start shopping. Note that 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 anew at the store, the transaction status becomes new. On the other hand, if the customer interrupts shopping at the store for some reason, a purchased product list screen corresponding to the transaction status up to that point is displayed on the mobile terminal 3.

(Product selection process)
Next, the product selection process will be explained. 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 purchase 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 a customer finds a product that he or she wants to purchase, he or she puts the mobile terminal 3 into the product reading mode and reads the product barcode 7 attached to the product using 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). Note that 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), it 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 a purchased product list screen.

Next, when the customer operates the mobile terminal 3 to change the quantity of the product as necessary, the mobile terminal 3 acquires the changed quantity (step S206: Yes). When a product barcode is read for the first time, the quantity of the product is automatically set to "1", but if the customer purchases multiple of the same product, the quantity can be set by operating the mobile terminal 3. 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), it 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 the customer has pressed the payment button 45 (step S211). The payment button 45 is a button that the customer presses when finishing 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 items or change quantities and continue shopping until he or she presses the payment button 45. Then, when the payment button 45 is pressed (step S211: Yes), the product selection process ends.

FIG. 9 shows an example of a purchase product list screen displayed on the mobile terminal 3. In this example, the purchased product list screen includes a product read 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 cancel button. 46. Note that the purchased product list screen is an example of a purchased product screen.

When the mobile terminal 3 detects that the product reading button 40 has been selected by a tap operation or the like, it switches the display on the display unit 31 to the product reading screen. On the product reading screen, the mobile terminal 3 displays images etc. acquired from the activated reading section 36. Thereby, the customer can read the product barcode 7 by moving the product or the mobile terminal 3 so that the product barcode 7 is located within the reading range of the reading unit 36.

The list display field 41 displays the name, quantity, and price of each purchased product. Further, for each purchased product in the list display field 41, a quantity decrease button 47 and a quantity increase button 48 are displayed. When the mobile terminal 3 receives a change in the quantity of the purchased product using 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 quantity after the change to the management server 2. .

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

When the mobile terminal 3 detects that the home screen transition button 44 has been 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 in 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 in response. Moreover, when the mobile terminal 3 detects that the transaction stop button 46 has been selected, it transmits information notifying the transaction stop to the management server 2. In this case, the management server 2 deletes the purchased product list corresponding to the mobile terminal 3.

(Accounting treatment)
Next, accounting processing will be explained. The accounting process is a process of paying for the product selected by the customer through the 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 aforementioned payment button 45 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). 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. The list display field 61 displays the name, quantity, and price of the purchased product. The subtotal display field 62 displays the subtotal of the sales prices of all purchased products displayed in the list display field 61, excluding tax, and the total amount display field 63 displays the total amount of sales prices of all purchased products, including tax. The customer looks at the payment method selection screen, confirms the payment amount, and presses either the credit button 64, the electronic money button 65, or the cash button 66. Note that although the payment method selection screen includes a list display field 61 and a subtotal display field 62, the present invention is not limited to this, and it is sufficient as long as 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 performs 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 making the credit payment, the credit card number, the payment amount, etc. When the mobile terminal 3 receives a payment request from the customer such as by pressing a payment button, the mobile terminal 3 prompts the customer to input a personal identification number, etc., as necessary, and performs credit card payment. In addition, customers can use their mobile device 3 by registering their credit card with the store operating company when registering as a member, or by registering with the payment processing company that the store has a contract with. It shall be possible to make credit card payments using it.

When the payment is completed, the mobile terminal 3 displays a checkout completion screen (step S308). FIG. 12(A) shows a display example of the checkout completion screen displayed on the display unit 31 when the credit card payment is completed. FIG. 12A shows an example when the customer selects credit card payment, and the checkout completion 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 payment method, such as the name of the card company. 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 on 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 types of electronic money that can be used for payment, the payment amount, and the like. When receiving a payment request from a customer such as by pressing a payment button, the mobile terminal 3 prompts the customer to select electronic money to be used for payment from among a plurality of electronic money, as necessary, and performs electronic money payment. When the payment is completed, the mobile terminal 3 displays a checkout completion screen (step S308). FIG. 12(B) is an example when the customer selects electronic money payment, and the checkout 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 amount of payment, the method of payment, for example, the name of the electronic money, and the balance of the electronic money. 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), respectively, so a description thereof will be omitted.

On the other hand, if the cash button 66 is pressed, that is, if the payment method is cash (step S306; Yes), the control unit 35 of the mobile terminal 3 transmits a cash payment request to the management server 2. When the management server 2 receives the cash payment request (step S309), it generates an accounting barcode based on the purchase item list at that time (step S310). The accounting barcode is information that uniquely identifies the purchase details indicated by the current purchased product list. In one example, the checkout barcode may be a random code that is uniquely associated with the current purchase. In this case, the accounting barcode serves 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 using 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. Note that the payment information includes details such as the total amount and the IDs and quantities of all products included in the purchased product list. The accounting machine 5 displays a cash payment screen based on the acquired payment information.

FIG. 14(A) shows a display example of the cash payment screen. On the cash payment screen, a total amount field 77 and a message prompting the user to insert cash into the cash slot are displayed. When the customer inserts cash into the cash slot, the accounting machine 5 pays change as necessary. When the cash payment is completed (step S315), the accounting machine 5 displays the accounting completion screen (step S316). FIG. 14(B) shows a display example of the checkout completion screen. FIG. 14(B) is an example when the customer selects cash payment, and the checkout completion screen includes a payment information field 78, a receipt button 79, and an end button 80. The payment information column 78 displays information such as the payment amount. 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), respectively, so their explanation will be omitted. When the customer presses the end button 80, 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. As shown in FIG. 13, a completion button 69 is also displayed on the payment screen displayed on the mobile terminal 3, and when the customer completes the transaction process, the customer presses the completion button 69 on the payment screen. When the completion button 69 is pressed, the mobile terminal 3 reports the completion of the payment to the management server 2 and returns the display section 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. Alternatively, the accounting barcode may include payment information. That is, when the management server 2 receives a cash payment request, it generates an accounting barcode based on the contents of the purchased product list at that time, using the total amount and information on the purchased product list. In this case, since the accounting machine 5 can acquire payment information by reading and decoding the accounting barcode, there is no need to communicate with the management server 2 to acquire payment information. That is, the accounting machine 5 only needs to extract the total amount from the read accounting barcode and display the payment method selection screen.

[Eat-in selection process]
As of October 2019, the consumption tax rate has been raised to 10%, and a reduced tax rate system has been introduced. The reduced tax rate is a consumption tax rate (for example, 8%) that is set lower than the standard tax rate (for example, 10%) for a specific product. Products to which the reduced tax rate is applied (hereinafter referred to as "products subject to the reduced tax rate") are, for example, food and beverages. However, if you eat in the purchased product, the reduced tax rate will not apply to that product and the standard tax rate will apply. Therefore, when a customer eats in, it is necessary to select and indicate the products to be eaten in advance before paying.

The eat-in selection process is a process of selecting a product for eat-in from among the food and beverage items that are purchased. FIG. 15 is a flowchart of the eat-in selection process. This process is executed by the mobile terminal 3 and the management server 2. When performing the eat-in selection process, the purchased product list screen includes an eat-in selection button 81 as shown in FIG. The eat-in selection button 81 is a button that, when pressed, transmits a eat-in selection request to the management server 2 and performs eat-in selection processing.

Basically, the customer registers the purchased product through the product selection process shown in FIG. 8, and when the eat-in selection button 81 is pressed on the purchased product list screen, the mobile terminal 3 executes the eat-in process. do.

First, the mobile terminal 3 determines whether the eat-in selection button 81 has been pressed (step S501). If the eat-in selection button 81 is not pressed (step S501; No), the mobile terminal 3 ends the eat-in selection process, returns to the purchase product list screen shown in FIG. 16, and performs the product selection process. On the other hand, if it is determined that the eat-in selection button 81 has been pressed (step S501), the mobile terminal 3 transmits a eat-in selection request to the management server 2 (step S501; Yes). When the management server 2 receives the eat-in selection request (step S502), it refers to the list of purchased products at that time and selects products eligible for eat-in (hereinafter referred to as "eat-in eligible products") from among the purchased products. Extract (step S503). The eat-in target product is a product that can be eaten or eaten within the store 8, and can be set arbitrarily, and the product identification information of the product is associated in advance with the fact that it is a eat-in target product. The management server 2 generates an eat-in selection screen based on the extracted eat-in target products and transmits it to the mobile terminal 3 (step S504).

The mobile terminal 3 displays the received eat-in selection screen on the display unit 31 (step S505). FIG. 17 is a display example of the eat-in selection screen. In this example, the eat-in selection screen includes a message prompting the user to select the eat-in target product and input the quantity, an eat-in display field 82, a quantity input field 83, a cancel button 84, and a confirm button 85. The eat-in display field 82 includes a quantity input field 83 for entering the name of the product to be eaten in extracted from the purchased products, the quantity to be eaten, and the number of purchased products that have already been registered (hereinafter referred to as "product quantity"). ) is displayed. With such an eat-in selection screen, the customer can easily input "what and how many items to eat in" from among the purchased products. When the cancel button 84 is pressed, the screen returns to the purchased product list screen. When the confirm button 85 is pressed, the quantity entered in the quantity input field 83 is confirmed as the number of eat-in target products.

In the quantity input field 83, the number of products to be eaten in (hereinafter referred to as "eat-in products") may be entered directly in numbers, or by tapping the name of the product to be eaten in in the eat-in display field 82, The quantity change screen shown in FIG. 18 may be displayed, and the number of eat-in products may be input from the quantity change screen. FIG. 18 shows a display example of a quantity change screen displayed by tapping focaccia in the eat-in display field 82. As shown in FIG. 18, the quantity change screen includes an all button 86, a decrease quantity button 87, an increase quantity button 88, a cancel button 89, a change button 90, the number of products 91, and the number of eat-in products 92. including. The customer can increase or decrease the number 92 of eat-in products by pressing the quantity decrease button 87 or quantity increase button 88. When the all button 86 is pressed, the total number of products 91 becomes the number of eat-in products 92. According to this, for example, if the number of products is large, such as "20", and the customer wants to input the number of eat-in products as "19", the customer presses the all button 86 and then presses the quantity decrease button. By pressing 87 once, you can easily input "19", which is convenient. When the cancel button 89 is pressed, the screen returns to the eat-in selection screen. When the change button 90 is pressed, the screen returns to the eat-in selection screen and the number in the quantity input field 83 is changed to the number 92 of the eat-in products on the quantity change screen.

In this embodiment, it is assumed that the quantity input field 83 on the eat-in selection screen and the number of eat-in products 92 on the quantity change screen are set to "0" in advance. However, the present invention is not limited to this, and any number can be set as long as it does not exceed the number of purchased items. Furthermore, if the customer wishes to cancel after selecting the eat-in product, the customer can change the number in the quantity input field 83 corresponding to the product selected as the eat-in product to "0" on the eat-in selection screen.

In this embodiment, the quantity change screen is displayed as a pop-up screen when the name of the product to be eaten in, etc. on the eat-in selection screen is tapped, so it can be said to be part of the eat-in selection screen. In this embodiment, the all button 86 is included in the quantity change screen, but the present invention is not limited to this, and may be included in the eat-in selection screen.

In this way, the mobile terminal 3 selects the eat-in product on the eat-in selection screen and inputs the number of the eat-in product (step S506). The customer presses the confirm button 85 to confirm the number of eat-in products. The mobile terminal 3 determines whether the confirm button 85 has been pressed (step S507). If it is determined that the confirm button 85 is not pressed (step S507; No), the mobile terminal 3 waits until the confirm button 85 is pressed. On the other hand, if it is determined that the confirm button 85 has been pressed (step S507; Yes), the mobile terminal 3 displays the product identification information of the eat-in product for which a number of "1" or more has been entered in the quantity input field 83, and the corresponding quantity input field. The number input in 83 is sent to the management server 2 as eat-in information (step S508).

The management server 2 receives the eat-in information from the mobile terminal 3 (step S509), and, based on the product information DB 28, calculates the tax-excluded price and tax-included price of the eat-in product and the tax-excluded selling price of all products in the purchase product list. The subtotal and the total amount including tax are calculated as the final price (step S510). Specifically, the management server 2 acquires the basic price of the eat-in product from the product information DB 28 based on the product identification information included in the eat-in information. Here, the basic price is the price that is the basis for calculating the tax-inclusive price, subtotal, and total amount, and in this embodiment, it is the tax-excluding price. The tax-included price is the tax-excluded price, which is the basic price, plus the consumption tax. It is assumed that the management server 2 stores information such as the standard tax rate regarding consumption tax and the reduced tax rate applied to some target products in the storage unit 23 as tax rate information.

For example, assume that the basic price of "focaccia" selected as an eat-in product is "192 yen." Eat-in products are not subject to the reduced tax rate but are subject to the standard tax rate, so the management server 2 sets the tax-included price of the "focaccia" to be eaten in as ``211 yen'', which is the price subject to 10% consumption tax, for example. calculate. Furthermore, since "focaccia" that is not eaten in is subject to the reduced tax rate, the tax-included price of "focaccia" that is not eaten in is, for example, 207 yen, which is the price subject to 8% consumption tax. Furthermore, the management server 2 calculates the subtotal excluding tax and the total amount including tax of the selling prices for all products in the purchased product list based on the calculated prices.

The management server 2 updates the purchased product list based on the calculated tax-excluded price and tax-included price of the eat-in products, and the tax-exclusive subtotal and tax-included total sales prices for all products in the purchased product list, and updates the purchased product list to the mobile terminal 3. (Step S511). The mobile terminal 3 displays the received purchased product list on the display unit 31 as a purchased product list screen (step S512). This ends the eat-in selection process. The customer continues to perform product selection processing and accounting processing from the purchased product list screen displayed on the mobile terminal 3.

FIG. 19 is a display example of the purchase product list screen after the eat-in product is selected. As shown in FIG. 19, the list display column 41 of the purchased product list screen displays eat-in product icons 94 in association with eat-in products. Note that for eat-in products, the quantity is input on the eat-in selection screen, so the corresponding quantity decrease button 47 and quantity increase button 48 do not exist.

According to this, the customer can easily select and confirm which of the purchased products to eat-in. In addition, eat-in products are not subject to the reduced tax rate even if they are food and beverages, and the standard rate consumption tax is applied, so the price is different from take-out even if the product is the same, but if the eat-in product icon 94 is You can easily recognize it.

For convenience of explanation, the list display field 41 of the purchased product list screen shown in FIGS. 16 and 19 displays both the tax-excluded price and the tax-included price as the price of the product. In addition, the total sales price including tax for all products in the purchased product list is calculated by summing the tax for each product. However, the present invention is not limited to this, and the list display field 41 may display either the tax-excluding price or the tax-included price, and the total amount may be the subtotal of products subject to the reduced tax rate and the price subject to the standard tax rate. The tax may be calculated by calculating the subtotal of the products, then taxing each item and adding them up.

[Product selection process with selling price change]
Next, a description will be given of the product selection process that involves changing the selling price. The product selection process that involves changing the selling price is a process in which when the purchased product or the number of purchased items corresponds to various discounts or discounts, it is reflected in the price, subtotal, and total amount on the purchased product list screen. In this case, basically, the customer registers the purchased product through the product selection process shown in FIG. 8, and performs the selling price change process described later at the timing when the purchased product list is updated. FIG. 20 shows a flowchart of product selection processing that involves changing selling prices.

In FIG. 20, the processing in steps S701 to S703 other than the selling price change processing, the processing in steps S705 to S709, and the processing in steps S711 to 713 are the processing in steps S201 to S203 in FIG. 8, and the processing in steps S204 to S208, respectively. Since the processing is the same as that of steps S209 to S211, the explanation will be omitted.
(Selling price change processing)
Next, the selling price change process will be explained. The selling price change process is a process of determining whether the purchased product or the number of purchased items corresponds to various discounts or discounts, and if applicable, changing the price. FIG. 21 is a flowchart of the selling price change process. This process is executed by the management server 2.

When the management server 2 receives the product identification information and quantity from the mobile terminal 3 (steps S703 and S709 in FIG. 20), it updates the purchased product list (step S601). Specifically, the management server 2 adds the product indicated by the received product identification information to the target purchase product list, and stores the updated purchase product list in the purchase product list DB 29. Then, the management server 2 determines whether the purchased product list corresponds to any of the selling price change conditions indicated by the selling price change information 27 (step S602). In other words, the management server 2 determines whether any of the selling price change conditions indicated by the selling price change information 27 is met based on the product identification information and the number of purchased products for each purchased product shown in the purchased product list.

If the updated purchased product list does not meet any of the selling price change conditions indicated by the selling price change information 27 (step S602; No), the management server 2 ends the selling price change process and carries out the selling price change shown in FIG. Return to the accompanying product selection process. On the other hand, if the updated purchased product list corresponds to any of the selling price change conditions indicated by the selling price change information 27 (step S602; Yes), the management server 2 stores the discount or value associated with the applicable selling price change condition. Based on the quotation, the price, subtotal, and total amount of the product that corresponds to the sales price change condition are calculated as the final price (step S603).

Specifically, the management server 2 acquires the basic price of the product that corresponds to the selling price change condition from the product information DB 28, and stores the basic price, the purchased product list, and the discount rate or/and associated with the applicable selling price change condition. and the discount amount, the tax-excluded price of the product is calculated as the changed price. Furthermore, based on the calculated change price, tax rate information, and purchased product list, the management server 2 calculates the tax-included price of the product, the subtotal excluding tax, and the total amount including tax of the selling prices for all products in the purchased product list. Calculate. In other words, in this example, the modified price obtained by applying the discount rate and/or discount amount to the tax-excluded price, which is the basic price, is the tax-excluded price of the product, and the price obtained by taxing the consumption tax on the modified price is the price of the product. The price includes tax. The management server 2 then ends the selling price change process and returns to the product selection process that involves changing the selling price.

Here, we will explain the selling price change process when the category "focaccia" that is eligible for discount is associated with the discount rate "10%" as category-specific discount information, and two focaccias are added to the purchase product list. do.

In the selling price change process, the management server 2 first receives the product identification information and the number of products for "focaccia" from the mobile terminal 3, and updates the purchased product list. Then, the management server 2 determines whether the updated purchase product list corresponds to any of the selling price change conditions indicated by the selling price change information 27 (step S602). At this time, the management server 2 determines that the selling price change condition for the classification discount is met (step S602; Yes). Therefore, the management server 2 calculates the price, subtotal, and total amount of "focaccia" based on the classified discount information (step S603).

Specifically, the management server 2 first obtains the basic price of "focaccia" (for example, 192 yen) from the product information DB 28 based on the product identification information. The basic price is the price excluding tax. Then, the management server 2 calculates the discount amount (19 yen) and the changed price of "focaccia" by subtracting the discount amount from the basic price, that is, the tax-excluded price after discount ( 173 yen). Furthermore, since the "focaccia" to be taken out is subject to the reduced tax rate, the management server 2 calculates the discounted tax-included price (186 yen) in which consumption tax (for example, 8%) is levied on the changed price. . The management server 2 also calculates the subtotal and total price of the purchased product list based on the calculated price. In this way, the management server 2 calculates the discounted tax-exclusive price and tax-included price of "focaccia" and the subtotal and total amount as the final price, based on the classified discount information.

Then, the management server 2 returns to the product selection process with the selling price change shown in FIG. 20, and updates the purchased product list based on the discounted tax-excluding price and tax-included price of "focaccia" and the subtotal and total amount. , and send it to the mobile terminal 3. FIG. 22 is a display example of a purchased product list screen including products to which classification discounts have been applied. The mobile terminal 3 displays a purchased product list screen as shown in FIG. 22 based on the received purchased product list. As shown in FIG. 22, the list display column 41 of the purchased product list screen displays a message 96 indicating "10% discount (-19 yen)," a tax-excluded price of "173 yen," and a tax-included price of "186 yen including tax." including.

In this way, when a discount or discount based on the selling price change information 27 occurs due to the registration of a purchased product, the management server 2 causes the discount or discount to be reflected on the purchased product list screen that is subsequently displayed. The price, subtotal, and total amount are displayed on the mobile terminal 3. Thereby, the management server 2 can make the customer using the mobile terminal 3 aware of the current accurate price. Moreover, the management server 2 can appropriately make the customer using the mobile terminal 3 aware of the existence of the discount/discount by clearly indicating the amount by which the price has changed on the purchased product list screen.

In addition, in the product selection process involving a selling price change, when the eat-in button 81 is pressed on the purchase product list screen, the mobile terminal 3 performs the eat-in selection process. At this time, in step S510 of the eat-in selection process shown in FIG. Calculate the price excluding tax. Then, the management server 2 calculates the tax-included price, subtotal, and total amount after applying the discount and/or discount of the purchased product based on the changed price. Specifically, in the above example of discounts by category for "focaccia", if one of the two "focaccia" is selected as an eat-in product, the management server 2 will give the reduced tax rate if it is a "focaccia" that is available for eat-in. Therefore, the tax-included price (190 yen) is calculated by adding consumption tax (for example, 10%) to the discounted tax-excluding price (173 yen). Then, the management server 2 calculates the subtotal and total amount of the purchased product list based on the calculated price. Furthermore, the management server 2 updates the purchased product list and sends it to the mobile terminal 3.

FIG. 23 is a display example of a purchase product list screen including eat-in products to which category-based discounts have been applied. Based on the received purchase product list, the mobile terminal 3 displays an eat-in product icon 94 and a message indicating "10% discount (-19 yen)" for "focaccia", which is an eat-in product, as shown in FIG. 96, the discounted tax-excluding price "173 yen", and the discounted tax-included price "190 yen including tax" are displayed.

In this manner, in the eat-in selection process, the management server 2 calculates the price, subtotal, and total amount of the purchased product after applying the applicable discount or discount. This is not limited to category-specific discounts, but applies to all discounts and discounts. For example, even if the basic price of "focaccia" is 192 yen per piece, but if you buy two at once, the price excluding tax after the discount will be 350 yen, the management server 2 will Calculate the price, subtotal, and total amount of purchased items by applying the following. At this time, the discounted tax-included price of the eat-in product is calculated by taxing the discounted tax-excluded price to which the bundle discount has been applied at the standard tax rate. In other words, even if one "focaccia" out of two purchased in bulk becomes an eat-in product, the bundle discount will be applied. Therefore, the mobile terminal 3 will display a purchased product list screen as shown in FIG. 24.

[Modified example]
(Modification 1)
In the above embodiment, the barcode given to the product is read by the mobile terminal 3, but instead, a QR (Quick Response) code may be given to the product and read by the mobile terminal 3. .

(Modification 2)

However, the present invention is not limited to this, and as shown in the purchase product list screen shown in FIG. A details confirmation button 95 may also be displayed. In this case, when the details confirmation button 95 is pressed, the mobile terminal 3 displays a details confirmation screen as shown in FIG. 25(B) based on the purchased product list. According to this, by selecting eat-in products, the list display column 41 on the purchase product list screen becomes long, and it is possible to eliminate the problem that it is difficult to grasp the purchase products.

(Modification 3)
In the above embodiment, as shown in FIG. 17, only eat-in products are extracted from the purchase product list and displayed in the eat-in display field 82 on the eat-in selection screen. However, the present invention is not limited to this, and after displaying all products included in the purchase product list in the eat-in display field 82, for example, products that are not eat-in products such as "pencils" cannot be selected. It is also possible to do so. According to this, it is possible to prevent a customer from misunderstanding that "pencils" which should have been registered as a purchased product have been deleted when looking at the eat-in display field 82 in which only eat-in products are displayed.
