Description

The present invention relates to a product sales data processing apparatus, a product sales data processing method, and a program.

Conventionally, in stores and the like, for example, products may be sold at a preferential price lower than the normal price. Among the products sold at the preferential price, there are quantity-limited products in which the sales quantity at the preferential price is limited. Limited quantity products may be sold to customers who meet certain special sale conditions, such as store members and customers who have coupons. As an example, a quantity-restricted product is a product that is sold at a preferential price (for example, a 10 yen discount) with only one item in one transaction, provided that the member is a member. In other words, even if a member purchases two items at the same time, one item will be sold at a preferential price and the other item will be sold at a regular price.

As a related technology, there is known a product sales data processing device that notifies an operator of the normal price and the special sale price of a special sale restricted product when the quantity of the special sale restricted product exceeds the limit in a transaction (for example). , See Patent Document 1 below.).

Here, the product sales data processing device (for example, a POS (Point Of Sales) register) may satisfy a condition (hereinafter referred to as "sale condition") of reading member information after registering a limited quantity product. .. Before the bargain sale condition is satisfied, the product sales data processing device registers the quantity-restricted product at the normal price regardless of whether the quantity-restricted product is within the quantity limit. Then, when the special sale condition is satisfied after registering the quantity-limited product, the product sales data processing device sets the product within the quantity limit as the preferential price and the product exceeding the quantity limit as the normal price as one product. to register.

JP-A-2015-121940

However, in the prior art, when the special sale condition is satisfied after registering the quantity-restricted product, even if the product within the quantity limit and the product exceeding the quantity limit are separately registered among the quantity-restricted products, the quantity limit is exceeded. The clerk may not notice that the product has been registered. For example, if there is a product registered after registering a quantity-restricted product, the product registered after that is displayed in the registered product list, so among the quantity-restricted products, the product that exceeds the quantity limit is registered. The clerk may not notice that he is there.

As a result, the clerk cannot make the customer confirm the customer's intention to purchase the product exceeding the quantity limit, and the product that the customer does not want to purchase may be registered. As described above, there is a problem that the conventional technique may not be able to satisfactorily register a product.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique capable of suitably registering a product.

In order to solve the above-mentioned problems, the product sales data processing device, which is one aspect of the present invention, is used as a product registration means for registering a product purchased by a customer and a quantity for sale at a preferential price lower than a normal price. When a condition for selling a limited quantity product with a limit is satisfied, a product determination means for determining whether or not the already registered product includes the limited quantity product, and the product determination. When it is determined that the quantity-restricted product is included, the quantity determination means for determining whether or not the quantity of the quantity-restricted product exceeds the quantity limit, and the quantity determination means exceeding the quantity limit. The product sales data processing device is provided with a notification means for notifying that there is the quantity-limited product that is not sold at the preferential price when it is determined to be present.

(Overview of each operation mode)
Subsequently, the operation mode of the POS terminal 20 will be described. The POS terminal 20 operates in one of a plurality of operation modes. The plurality of operation modes are operation modes during normal business (operation modes related to registration processing and settlement processing). Specifically, the plurality of operation modes are a normal mode, an accounting-only mode, and a full self-mode. Hereinafter, each mode of the normal mode, the accounting-only mode, and the full self mode will be briefly described.

(Normal mode)
The normal mode is an operation mode in which the registration of the product on the clerk side (hereinafter, may be referred to as "product registration") and the settlement on the customer side are enabled, and the product registration on the customer side is invalidated. That is, the normal mode is an operation mode in which the registration process on the clerk side is executed without executing the registration process on the customer side. In the product registration on the clerk side, the purchased product is registered using the scanner unit 212 on the clerk side, the display unit 210 on the clerk side, and the key operation unit 211. In the normal mode, it is possible to make payments such as inserting coins (banknotes and coins) and reading various cards. In the normal mode, it is possible to start the settlement (for example, to insert money) even when the product registration process is being performed. However, in the present specification, the settlement in the normal mode will be described as being started after the registration of the product is completed in principle. In the following, the settlement in the normal mode may be referred to as "face-to-face settlement".

Further, in the normal mode, the registration information can be transmitted to another POS terminal 20. The transmission of the registration information to the other POS terminal 20 is to transmit the registration information generated in the registration process to another POS terminal 20 (POS terminal 20 in the accounting-only mode) capable of executing the settlement process. .. Also, in the normal mode, it is possible to issue a checkout ticket. Issuing an accounting ticket is to encode the registration information and the like generated in the registration process, print it on a print medium (accounting ticket), and output it. The other POS terminal 20 can perform the settlement process by reading the code of the accounting ticket.

(Accounting-only mode)
The accounting-only mode is an operation mode in which the product registration on the clerk side and the customer side is invalidated and the payment on the customer side is enabled. Specifically, the accounting-only mode enables reception of registration information from another POS terminal 20 (POS terminal 20 in normal mode), reading of accounting tickets, and insertion of money, and is a product on the clerk side and the customer side. This is the operation mode in which registration is disabled. Receiving the registration information from the other POS terminal 20 is a function of receiving the registration information generated in the registration process of the other POS terminal 20. Reading a checkout is to read the code printed on the checkout or to read the coded information. The accounting-only mode is an operation mode in which the registration process is not executed in the own terminal, but the settlement process is executed exclusively based on the registration information generated in the other POS terminal 20. In the accounting-only mode, transmission of registration information to another POS terminal 20 and issuance of accounting tickets are invalid.

(Full self mode)
The full self mode is an operation mode in which the product registration on the clerk side is invalidated and the product registration and settlement on the customer side are enabled. Specifically, the full self mode is an operation mode premised on the registration process on the customer side. In the product registration on the customer side, the purchased product is registered using the scanner unit 206 on the customer side and the display unit 205 on the customer side. Further, the full self mode is an operation mode in which the settlement process can be performed on the own terminal. Specifically, the full self-mode is an operation mode in which product registration and money input on the customer side are enabled. In the full self mode, transmission of registration information to another POS terminal 20 and issuance of a checkout ticket are invalid.

(Example of special sale restricted product table)
Next, the special sale restricted product table will be described with reference to FIG.
FIG. 4 is an explanatory diagram showing an example of a bargain sale restricted product table. Here, in the present specification, "sale" means selling an item at a price lower than a normal price. "Sale" is not limited to selling goods at a low price for a limited period or quantity. "Sale" shall include selling goods at a low price without limiting the period or quantity. In addition, the "sale price" indicates that the price is lower than the normal price, which is an example of the preferential price. The "sale-restricted product" is a product in which the sales quantity is limited at a special sale price, which is cheaper than the normal price, and is an example of a quantity-restricted product. The special sale restricted product table 400 shown in FIG. 4 is stored in, for example, the store controller 10. However, the bargain sale restricted product table 400 may be stored in the POS terminal 20 or may be stored in an external server device.

As shown in FIG. 4, the special sale restricted product table 400 includes items such as a product code, a special sale restricted product, a special sale condition, a normal price, a special sale information, and a quantity limit. The information associated with the information of each item is the special sale restricted product information. The product code is a code attached to each product, and is identification information for uniquely identifying the product. The special sale restricted product indicates the product name of the special sale restricted product. The special sale condition is a condition that is subject to the special sale. Specifically, the special sale conditions are conditions such as being a member, applying a coupon, and having a purchase price of a certain amount or more.

The normal price is the normal price when the bargain sale restricted product does not become a bargain sale, in other words, the price of the bargain sale restricted product when the bargain sale condition is not satisfied. The bargain sale information is information regarding a discount on the regular price. Specifically, the special sale information is information indicating, for example, 10% OFF, 50 yen discount, 20% OFF, etc. with respect to the normal price. The quantity limit is the maximum quantity that can be sold at a bargain price if the bargain conditions are met.

To give an example, the special sale restricted product information 400a indicates that up to 3 pieces of "○○ juice" can be discounted from the normal price by 10% on condition that the member is a member. Specifically, the special sale restricted product information 400a has a product code of "○○○○", a special sale restricted product name of "○○ juice", a special sale condition of "member", a regular price of "100 yen", and special sale information. Indicates that "10% OFF" and the quantity limit is "3 pieces".

(Regarding the functional configuration performed by the POS terminal 20 when a bargain sale restricted product is registered)
Next, the functional configuration performed by the POS terminal 20 when the bargain sale restricted product is registered will be described. In the following, the description will be made on the assumption that face-to-face settlement is performed in the normal mode. Further, in the present embodiment, the POS terminal 20 will be described as an example of the product sales data processing device. However, the product sales data processing device is not limited to the POS terminal 20, and may be a ticket vending machine (for example, a touch panel type ticket vending machine).

The POS terminal 20 includes a product registration unit, a product determination unit, a quantity determination unit, a notification unit, and a subtraction unit. These functional units are realized by the CPU 201. That is, the CPU 201 realizes these functions by executing a predetermined program (for example, a product sales data processing program).

The product registration unit registers the product purchased by the customer. The product registration unit is based on, for example, the content that the store clerk side display unit 210 and the key operation unit 211 accept the operation of the store clerk, and the content that the store clerk side scanner unit 212 reads the barcode attached to the product. To register.

When the special sale condition for selling the special sale restricted product is satisfied, the product determination unit determines whether or not the registered product already registered by the product registration unit includes the special sale restricted product. The special sale condition is, for example, a condition that can be satisfied during the registration of the product by the product registration unit (between the start of the product registration and the start of the settlement). Specifically, the special sale condition includes a condition that member information or coupon information is acquired when there is a registered product that has already been registered. In addition, the special sale condition includes a condition that the purchase price is a certain amount or more when there is a registered product that has already been registered.

The product determination is, for example, a determination as to whether or not the special sale restricted product information including the same product code as the product code of the registered product is stored in the special sale restricted product table 400 (see FIG. 4). In addition, the product judgment is not performed when the special sale condition is not satisfied. Further, in the present embodiment, the product determination is not performed at the timing when the special sale restricted product is registered, but at the timing when the special sale condition is satisfied. If the special sale condition is satisfied first (the "preliminary special sale condition" described later is satisfied), the product determination is performed at the timing when the special sale restricted product is registered.

When it is determined in the product determination that the special sale restricted product is included, the quantity determination unit determines the quantity of the registered special sale restricted product whether or not the quantity exceeds the quantity limit. Specifically, the quantity determination refers to the special sale restricted product table 400 (see FIG. 4), and whether or not the quantity of the registered special sale restricted product exceeds the quantity limit included in the special sale restricted product information. It is a judgment.

When it is determined in the quantity determination that the quantity limit has been exceeded, the notification unit notifies that there is a special sale restricted product (hereinafter referred to as "special sale exclusion product") that is not sold at the special sale price (hereinafter referred to as "special sale exclusion notification"). I do. The special sale exclusion notification is a notification indicating that there is a special sale exclusion product by display or voice. For example, the notification unit displays a pop-up on the store clerk side display unit 210 to notify the special sale condition.

If it is determined in the quantity determination that the quantity limit is not exceeded, the notification unit may notify that there is a special sale restricted product to be sold at the special sale price. In addition, the notification unit notifies that there is a special sale restricted product sold at the special sale price because there is a special sale restricted product sold at the special sale price even if it is determined in the quantity determination that the quantity limit is exceeded. May be done. In this case, for example, the notification unit may notify that there is a special sale restricted product sold at a special sale price together with the special sale exclusion notification.

In addition, a special sale condition (hereinafter referred to as "advance special sale condition") may be established before the product is registered by the product registration department. The pre-sale condition is established, for example, by the POS terminal 20 reading the member information or reading the coupon information before registering the product. Even if the pre-sale conditions are met, the product judgment and quantity judgment are performed. When the pre-sale condition is satisfied, the product determination and the quantity determination are performed at the timing of registering the product. Therefore, when the pre-sale condition is satisfied and it is determined in the quantity determination that the quantity limit is exceeded, the display screen is displayed to the effect that the special sale exclusion product is registered. As a result, the clerk can grasp that there is a special sale excluded product at the same time as the product is registered. Therefore, when the pre-sale condition is satisfied and it is determined in the quantity determination that the quantity limit is exceeded, the notification unit may not perform the special sale exclusion notification. However, not limited to this, when the advance special sale condition is satisfied, the notification unit may perform the special sale exclusion notification even if it is determined in the quantity determination that the quantity limit is exceeded.

(About the display of the registered product list)
In the present embodiment, the POS terminal 20 includes a display unit. The display unit is, for example, a store clerk side display unit 210. However, the display unit may be the customer side display unit 205. The display unit displays a registered product list showing the registered products registered by the product registration unit. The registered product list is a display showing a registered product, for example, a product name, a unit price (regular price), a purchase price of the product, a discount amount, a special sale information (10% OFF, etc.), and the like.

The registered product list is a list that can display a certain number of registered products on the screen. In the registered product list, for example, the most recently registered product and the product registered earlier based on the product are displayed in chronological order. Specifically, if the number of registered products exceeds a certain number and a new product is registered, the products already registered will not be displayed on the screen in order from the previously registered product. In the registered product list, the number of displayed products may be changed according to the settings and the like. For example, the registered product list may display all registered products.

When the notification unit determines that the quantity limit has been exceeded in the quantity determination, the registered product list includes the special sale restricted product (hereinafter referred to as "special sale target product") having a special sale price within the range of the quantity limit and the quantity. Display the regular priced special sale restricted products (special sale excluded products) that exceed the limit. For example, the notification unit displays the special sale target product and the special sale exclusion product separately in the registered product list.

Here, for example, when the number of registered products exceeds a certain number, the special sale restricted products may not be displayed on the current display screen. In this case, the notification unit causes the registered product list to display the special sale target product and the special sale excluded product instead of the product in the registered product list currently displayed.

In addition, the notification unit displays that the regular priced special sale restricted product (special sale excluded product) is not sold at the special sale price. Specifically, the notification unit displays, for example, a display area in which the bargain-excluded product is displayed in a mode different from the display area in which the normal product is displayed (for example, a conspicuous mode). The display indicating that the bargain-excluded product is not sold at the bargain price may be, for example, a display for notifying the fact by using characters, symbols, or the like.

(About changing the quantity of special sale restricted products)
In the present embodiment, the POS terminal 20 includes a reception unit. The reception unit is, for example, a store clerk side display unit 210 or a key operation unit 211. The reception department accepts changes in the quantity of registered products. In addition, the reception department accepts changes in the quantity of bargain-restricted products. When the reception unit accepts a change in the quantity of the special sale restricted product, the notification unit notifies that the special sale restricted product that has exceeded the quantity limit does not exceed the quantity limit. Specifically, for example, when the quantity limit of the special sale restricted product is "3" and the quantity of the registered special sale restricted product is "5", the quantity of the registered special sale restricted product is "3". When the change in quantity is accepted, we will notify you that there are no more products excluded from special sale. The mode of the notification is display or voice. When the mode of notification is displayed, the mode of notification may be, for example, a mode of characters or symbols.

In addition, the subtraction unit reduces the quantity of the special sale restricted products that exceed the quantity limit when the reception unit accepts a change to reduce the quantity of the special sale restricted products. For example, if there is a special sale excluded product, the subtraction unit preferentially reduces the quantity of the special sale excluded product even if the reception unit accepts a change to reduce the quantity of the special sale target product.

(An example of processing related to the special sale exclusion notification performed by the POS terminal 20)
FIG. 5 is a flowchart showing an example of processing related to the special sale exclusion notification performed by the POS terminal 20. In FIG. 5, the POS terminal 20 determines whether or not the bargain sale condition is satisfied (step S501). The condition for the special sale condition is to acquire member information and coupon information, and to purchase a certain amount or more. The POS terminal 20 waits until the bargain sale condition is satisfied (step S501: NO). When the special sale condition is satisfied (step S501: YES), the POS terminal 20 determines whether or not there is a product (registered product) that has already been registered (step S502).

If there is no registered product (step S502: NO), that is, if the special sale condition is satisfied before the product is registered, the POS terminal 20 ends the process as it is. When there is a registered product (step S502: YES), the POS terminal 20 determines whether or not the registered product includes a special sale restricted product (step S503). When the special sale restricted product is not included in the registered product (step S503: NO), the POS terminal 20 ends the process as it is. When the special sale restricted product is included in the registered product (step S503: YES), the POS terminal 20 determines whether or not the quantity of the special sale restricted product exceeds the quantity limit (step S504).

If the quantity of the bargain sale restricted product does not exceed the quantity limit (step S504: NO), the POS terminal 20 proceeds to step S508. When the quantity of the special sale restricted product exceeds the quantity limit (step S504: YES), the special sale exclusion notification (notification that there is a special sale excluded product) is performed (step S505). Then, the POS terminal 20 displays the special sale exclusion product (the special sale restricted product is sold at the normal price) (step S506). Further, the POS terminal 20 displays that the bargain sale exclusion product is not sold at the bargain sale price (step S507). Then, the POS terminal 20 displays the special sale target product (the special sale restricted product is sold at the special sale price) (step S508), and ends a series of processing.

(An example of the quantity change processing of the bargain sale restricted product performed by the POS terminal 20)
FIG. 6 is a flowchart showing an example of the quantity change processing of the bargain sale restricted product performed by the POS terminal 20. In FIG. 6, the POS terminal 20 determines whether or not the subtraction of the registered product has been accepted (step S601). The POS terminal 20 waits until the subtraction of the registered product is accepted (step S601: NO). When the subtraction of the registered product is accepted (step S601: YES), the POS terminal 20 determines whether or not the product for which the subtraction is accepted is a bargain sale restricted product (step S602).

When the product for which the subtraction is accepted is a bargain sale restricted product (step S602: YES), the POS terminal 20 determines whether or not the bargain sale restricted product exceeds the quantity limit (step S603). When the special sale restricted product exceeds the quantity limit (step S603: YES), the POS terminal 20 subtracts the quantity of the special sale excluded product (step S604).

Then, the POS terminal 20 displays the quantity after subtraction (step S605), and ends a series of processes. In step S602, when the product for which subtraction is accepted is not a bargain sale restricted product (step S602: NO), the POS terminal 20 subtracts the quantity of the accepted product (step S606), and proceeds to step S605. Further, in step S603, when the special sale restricted product does not exceed the quantity limit (step S603: NO), the POS terminal 20 proceeds to step S606.

When the error notification 1500 is displayed, for example, the clerk tells the customer that the bargain sale has been invalidated, and depending on the customer's reply, the bargain sale restricted product is subtracted, or other registered products are canceled. It is possible to do.

In the above description, the case where the bargain sale restricted product is displayed in the current registered product list has been described. However, there are cases where the bargain sale restricted product is registered in the number of stages (for example, the 100th stage) that is not displayed in the current registered product list. In this case as well, the error notification 1500 is displayed. For example, if a special sale restricted product is registered in the 100th row and the special sale target product and the special sale exclusion product are displayed separately, even if the 250th row is exceeded, the special sale target product and the special sale exclusion product are divided. Cannot be displayed. Therefore, even in such a case, the error notification 1500 is displayed.

(Regarding the functional configuration of the POS terminal 20 according to the second modification)
Next, the functional configuration of the POS terminal 20 according to the second modification will be described. The registered product list is preset with an upper limit number (for example, 250) in which registered products can be displayed. Even if it is determined that the quantity limit has been exceeded in the quantity determination of the special sale restricted product, if the notification unit displays the special sale target product and the special sale excluded product in the registered product list, the notification unit may exceed the upper limit. Displays an error.

According to the second modification, it is possible to make the clerk aware that there is a bargain sale restricted product for which the bargain sale is invalidated because the total score reaches the upper limit. Then, the clerk can ask the customer what to do with the bargain-restricted product. Therefore, since it is possible to confirm the customer's intention to purchase the bargain-restricted product, it is possible to prevent the customer from registering the product that the customer does not want to purchase.

(Modification 3)
In the above-described embodiment, the configuration in which the special sale exclusion notification 710 is performed using the store clerk side display unit 210 has been described. In addition to or instead of such a configuration, in the modified example 3, a configuration in which the special sale exclusion notification 710 is performed by using the customer side display unit 205 will be described.

In the third modification, the POS terminal 20 causes the customer side display unit 205 to display the special sale exclusion notification 710 when the special sale condition such as acquisition of member information is satisfied and the quantity limit of the special sale restricted product is exceeded. .. Further, when the special sale exclusion notification 710 is displayed on the customer side display unit 205, the POS terminal 20 accepts the customer to select the processing for the special sale exclusion product or accepts the subtraction of the special sale restricted product. You may. Specifically, the POS terminal 20 has a selection reminder notification 810 (see FIG. 8A), a subtraction reception screen 820 (see FIG. 8B), an invalidation cancellation notification 900 (see FIG. 9A), and the like. May be displayed on the customer side display unit 205. It is desirable that the special sale price button 812 included in the selection reminder notification 810 is displayed when an authorized clerk such as a store manager operates the button. Therefore, when displaying the selection reminder notification 810 on the customer side display unit 205, the bargain price button 812 may not be displayed.

Further, the customer side display unit 205 may be used to perform the special sale exclusion notification 710 even when the POS terminal 20 is controlled to the full self mode. In the full self mode, the customer is allowed to read the coupon information. Therefore, if the coupon is a paper medium, it may be necessary to collect the coupon. In this case, the POS terminal 20 may call the clerk when the coupon information is read. Further, for example, if the coupon is a one-time barcode, it is not necessary to collect the coupon, so that the clerk may not be called.

According to the third modification, it is possible to directly notify the customer that the special sale exclusion product is registered among the special sale restricted products. Therefore, it is possible to prevent the registration of products that the customer does not want to purchase.

(Modification example 4)
In the above-described embodiment, the POS system 1 in which the POS terminal 20 accepts the product registration operation has been described. In the fourth modification, a shopping system in which a mobile terminal operated by a customer accepts a product registration operation will be described. In the fourth modification, the shopping system includes a mobile terminal, a payment device, and a cloud server. The mobile terminal may be a terminal device owned by the customer or a terminal device rented by the store. Further, the mobile terminal may be installed in a shopping cart or may be held by a customer.

In the shopping system, the product read by the mobile terminal is registered in the cloud server. Then, at the time of settlement, the settlement device receives the registration information used for the settlement from the cloud server, so that the settlement is performed. The flow from product registration to payment in the shopping system will be briefly explained below.
(1) The customer uses the camera function of the mobile terminal to read the product code (for example, a barcode) attached to the product. When the mobile terminal reads the product code, the mobile terminal transmits the product code information indicated by the read product code to the cloud server.
(2) The cloud server stores cart information including cart identification information that identifies a customer (mobile terminal). When the cloud server receives the product code information from the mobile terminal, the cloud server stores the product indicated by the product code information in the cart information. The mobile terminal transmits the product code information to the cloud server each time the product code is read. However, the mobile terminal may sequentially store the read product code information and collectively send the product code information to the cloud server at the timing when the payment start is accepted.
(3) When the registration of the product to be purchased is completed, the customer presses the payment start button displayed on the mobile terminal. When the mobile terminal receives the press of the checkout start button, the cart identification information is coded (for example, a two-dimensional code) and displayed on the display unit (touch panel) of the mobile terminal.
(4) Then, the customer causes the reading unit of the settlement device to read the two-dimensional code. When the settlement device reads the two-dimensional code, it transmits the cart identification information indicated by the read two-dimensional code to the cloud server, and also requests the cloud server to transmit the registration information necessary for settlement.
(5) When the cloud server receives the transmission request of the registration information from the settlement device, the cloud server identifies the cart information using the cart identification information received together with the transmission request and generates the registration information. Then, the cloud server transmits the generated registration information to the settlement device.
(6) When the settlement device receives the registration information from the cloud server, the settlement device starts the settlement using the received registration information.

In addition, the mobile terminal displays the registered product list based on the control (of the notification unit) of the cloud server. In addition, the mobile terminal is provided with a reception unit (touch panel), accepts a change in the quantity of registered products by the function of the reception unit, and transmits information indicating the change in the quantity to the cloud server. When the subtraction unit of the cloud server receives information indicating the change in quantity from the mobile terminal, it reduces the quantity of the bargain-restricted products that exceed the quantity limit. The mobile terminal displays a screen on the display unit in which the quantity of the bargain-restricted products is reduced based on the instruction of the subtraction unit.

In this way, in the shopping system, it is possible to display the special sale exclusion notification on the display unit of the mobile terminal. As a result, the customer can be made aware that the bargain-excluded product is registered in the middle of shopping. Then, since the customer can change the quantity and the like, it is possible to prevent the customer from registering a product that he / she does not want to purchase.

Further, in the modification 4, the special sale exclusion notification (see the special sale exclusion notification 710 in FIG. 7B) is not limited to being displayed on the mobile terminal. For example, the special sale exclusion notification (see the special sale exclusion notification 710 in FIG. 7B) may be displayed on the checkout device in addition to or in place of the mobile terminal. Specifically, when the settlement device acquires membership information and coupon information by reading the membership card and coupon presented by the customer after starting settlement (after receiving the registration information from the cloud server). There is. In this case, the settlement device transmits the acquired member information and coupon information to the cloud server. When the cloud server receives the member information and the coupon information, the cloud server determines the product and the quantity. Then, when the notification unit of the cloud server determines that the quantity limit has been exceeded in the quantity determination, it controls to transmit information to the effect that the special sale exclusion notification (notification that there is a special sale excluded product) is performed to the settlement device. conduct.

When the settlement device receives information from the cloud server to the effect that the special sale exclusion notification is to be performed, the settlement device displays the special sale exclusion notification on the display unit (touch panel) of the settlement device. In addition, the settlement device displays a list of registered products based on the control of the notification unit of the cloud server. In addition, the settlement device is provided with a reception unit (touch panel), accepts a change in the quantity of registered products by the function of the reception unit, and transmits information indicating the change in the quantity to the cloud server. When the subtraction unit of the cloud server receives information indicating the change in quantity from the settlement device, it reduces the quantity of the bargain-restricted products that exceed the quantity limit. The settlement device displays a screen on the display unit in which the quantity of the bargain-restricted products is reduced based on the instruction of the subtraction unit.

In this way, in the shopping system, it is possible to display the special sale exclusion notification on the display unit of the settlement device. As a result, the customer can be made aware that the special sale exclusion product is registered at the time of payment. Then, since the customer can change the quantity and the like, it is possible to prevent the customer from registering a product that he / she does not want to purchase.

In the shopping system, a configuration is described in which a customer picks up a product, registers it, and makes a payment, but the present invention is not limited to this. For example, the customer may register the product in advance, place an order, and settle the payment at the terminal (payment device) of the store. In such a configuration, when the payment device reads the membership card or coupon presented by the customer at the time of payment, the member information or coupon information is transmitted to the cloud server, and the special sale exclusion notification is sent based on the instruction of the cloud server. It should be displayed. Even in such a configuration, the mobile terminal can display the special sale exclusion notification.
