[Overview of payment processing device 1]
FIG. 1 is a diagram showing an outline of a payment processing device 1 according to the present embodiment. The payment processing device 1 is a server that performs payment processing and return processing related to the return of goods after payment. The payment processing device 1 is communicably connected to the store terminal 2 via a communication network such as an internet line or a mobile phone network. The store terminal 2 is, for example, a POS terminal, but is not limited to this, and may be a mobile terminal such as a tablet or a smartphone. In the following description, products and services are collectively referred to as products.

In the present embodiment, the store terminal 2 transmits a payment request related to the payment of the product ((1) in FIG. 1). The payment processing device 1 receives the payment request by receiving the payment request. The settlement request contains coupon information indicating a coupon to which a discount such as a fixed amount or a fixed percentage is applied provided that the total purchase amount of one or more products in one transaction is equal to or more than a predetermined amount. It is assumed that there is.

The payment processing device 1 determines whether or not the coupon can be applied by determining whether or not the total purchase amount of the product is equal to or greater than the predetermined amount ((2) in FIG. 1). Then, when the payment processing device 1 determines that the total purchase amount of the product is equal to or more than the predetermined amount, the discount by the coupon is applied, and the payment is made at the discounted amount obtained by subtracting the discount amount corresponding to the discount from the total amount. ((3) in FIG. 1).

After that, the payment processing device 1 receives a return request for at least one of the one or more products purchased in the transaction from the store terminal 2 ((4) in FIG. 1). Even if the payment processing device 1 does not meet the conditions for applying the coupon when the return request is received, the payment processing device 1 performs the return processing without collecting the purchase price ((5) in FIG. 1).

For example, in the payment processing device 1, the deducted amount, which is the total amount minus the amount of the product corresponding to the return request, does not meet the lower limit amount (predetermined amount) which is the application condition of the coupon, and the discount is given to the total amount. If the amount is more than the discounted amount after application, the return will be processed without collecting the purchase amount.

By doing so, the payment processing device 1 can perform an appropriate return processing based on the conditions of the discount. In addition, the user who purchased the product will not be charged the purchase price when returning the product. In addition, the clerk does not collect any additional charges when returning the product, so he does not explain the additional charges. Therefore, the payment processing device 1 can reduce the burden on the clerk and the user when returning the product.

[Configuration of payment processing device 1]
Subsequently, the configuration of the payment processing device 1 will be described. FIG. 2 is a diagram showing a configuration of a payment processing device 1 according to the present embodiment. As shown in FIG. 2, the payment processing device 1 includes a communication unit 11, a storage unit 12, and a control unit 13.

The communication unit 11 is an interface for connecting to a communication network such as an Internet line or a mobile phone network.
The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 12 stores a program executed by the control unit 13. For example, the storage unit 12 stores a payment processing program that causes the control unit 13 to function as a payment request reception unit 131, a payment unit 132, a return request reception unit 133, a return processing unit 134, and a notification unit 135.

Further, the storage unit 12 stores payment history information indicating the payment history. FIG. 3 is a diagram showing an example of payment history information. The settlement history information includes, for example, a transaction ID for identifying a transaction corresponding to settlement, a transaction date and time indicating the date and time when the transaction was performed, the total amount of products in the transaction, and a coupon applied to the transaction. It is information associating the coupon ID for identifying the above, the discount amount by the coupon, and the discounted amount which is the amount obtained by subtracting the discount amount from the total amount.

Further, the storage unit 12 stores the return history information indicating the return history. FIG. 4 is a diagram showing an example of return history information. The return history information includes, for example, a transaction ID for identifying the transaction for which the return request was made, a return date and time indicating the date and time when the return request was made, and a refund request which is the amount of the product corresponding to the return request. Information that associates the amount with the refund amount, which is the amount refunded in response to the return request, and the remaining discount amount indicating the remaining amount of the discount amount. It is assumed that the initial value of the remaining discount amount is the discount amount and the minimum value is 0.

The control unit 13 is, for example, a CPU (Central Processing Unit). By executing the program stored in the storage unit 12, the control unit 13 functions as a settlement request receiving unit 131, a settlement unit 132, a return request receiving unit 133, a return processing unit 134, and a notification unit 135.

The settlement request receiving unit 131 uses a coupon to which a fixed amount or a fixed percentage discount is applied on condition that the total purchase amount of one or more products in one transaction is equal to or more than a predetermined amount. Accept payment requests.

For example, the payment request receiving unit 131 reads from the payment code for the user who purchases the product to make a payment at the store by the store terminal 2 used at the store selling the product or the user terminal such as the user's mobile terminal. The payment request is accepted by acquiring the payment request for making the payment. The settlement request shall include the total purchase price of one or more products. Further, when the user uses the coupon, it is assumed that the coupon information indicating the coupon is included in the payment request.

When the settlement request receiving unit 131 receives the settlement request, the settlement unit 132 makes a settlement. When the coupon information is included in the settlement request and the total amount included in the settlement request is equal to or greater than the predetermined amount, the settlement unit 132 setstles at the discounted amount obtained by subtracting the discount amount corresponding to the discount from the total amount. do.

FIG. 5 is a diagram showing an example of a discount based on a coupon. FIG. 5 shows the relationship between the total purchase amount when a certain amount is discounted by the coupon and the payment amount of the user. In FIG. 5, the solid line and the broken line extending from the origin are lines where the total purchase amount and the user's payment amount are equal to each other. Further, in FIG. 5, the amount Th indicates a predetermined amount to which the coupon is applied. The total amount P indicates the total amount of the purchase amount of the user in a certain transaction. The discounted amount Pd indicates the discounted amount after the transaction is discounted by the coupon. Further, the amount D indicates a discount amount discounted by applying the coupon. When the discount amount D is a fixed amount, as shown in FIG. 5, the discount amount D is deducted from the total amount P on the condition that the total amount of the purchase amount exceeds the predetermined amount, and the discount amount is discounted as the user's payment amount. The post-amount Pd = PD is calculated.

The settlement unit 132 makes a settlement and generates a transaction ID as transaction identification information for identifying a transaction related to the settlement. The settlement unit 132 associates the generated transaction ID, the transaction date and time, the total amount included in the settlement request, the coupon ID indicated by the coupon information included in the settlement request, the discount amount by the coupon, and the discounted amount. It is stored in the storage unit 12 as payment history information.

When the settlement is completed, the settlement unit 132 notifies the store terminal 2 of the transaction ID, the total amount, the discount amount, and the discounted amount. As a result, the store terminal 2 can issue a receipt including the transaction ID. Receipts are used to accept return requests. When the settlement is completed, the settlement unit 132 notifies the store terminal 2 of the transaction ID, the total amount, the discount amount, and the discounted amount, but the present invention is not limited to this. For example, when the payment request receiving unit 131 acquires a payment request from a user terminal used by the user, the payment unit 132 transfers the transaction ID, the total amount, the discount amount, and the discounted amount to the user terminal. It may be sent to notify that the payment has been completed.

The return request receiving unit 133 accepts a return request for at least one of the one or more products purchased in the transaction in which the settlement unit 132 has settled. Specifically, the return request receiving unit 133 receives a return request from the store terminal 2 by receiving the return request including the transaction ID and the amount of the return target product corresponding to the transaction corresponding to the transaction ID. accept. Here, the return request receiving unit 133 may accept the return request a plurality of times in response to the transaction.

The return processing unit 134 performs return processing when the return request reception unit 133 receives the return request. First, the return processing unit 134 refers to the payment history information stored in the storage unit 12, and specifies the total amount of transactions corresponding to the transaction ID included in the return request. Further, the return processing unit 134 refers to the payment history information stored in the storage unit 12, and based on the coupon ID of the coupon applied to the transaction corresponding to the return request, the predetermined amount to which the coupon is applied. To identify. Further, the return processing unit 134 refers to the return history information stored in the storage unit 12, and determines the cumulative amount of the refund request amount associated with the transaction ID included in the return request, the cumulative amount of the refund amount, and the cumulative amount of the refund amount. Calculate the remaining discount amount.

Then, the return processing unit 134 calculates the deducted amount, which is the total amount minus the cumulative amount of the product corresponding to the return request (cumulative amount of the refund request amount). When the deducted amount is equal to or greater than the predetermined amount, the return processing unit 134 refunds the difference between the amount after the discount is applied to the total amount and the amount after the discount is applied to the deducted amount. Further, the return processing unit 134 processes the returned goods without refunding the amount of the product when the deducted amount is less than the predetermined amount and the deducted amount is equal to or more than the discounted amount. Further, when the deducted amount is less than the predetermined amount and the deducted amount is less than the discounted amount, the return processing unit 134 refunds the amount obtained by subtracting the deducted amount from the discounted amount.

FIG. 6 is a diagram illustrating the return processing by the return processing unit 134. FIG. 6 is a partially enlarged view of the graph shown in FIG. In the example shown in FIG. 6, for the sake of simplicity, an example in which a return request is made once is shown. In FIG. 6, Pr is the amount of goods corresponding to the return request.

First, the return processing unit 134 determines whether or not the deducted amount P-Pr, which is the amount after deducting the amount Pr of the product corresponding to the return request from the total amount P of the purchase amount, is the predetermined amount Th or more. To judge. When the return processing unit 134 determines that the deducted amount P-Pr is equal to or greater than the predetermined amount Th, the discount applied amount (discounted amount) PD for the total amount and the discount applied to the deducted amount. After that, the difference Pr from the amount P-Pr-D is refunded. FIG. 6A shows an example in which the deducted amount P-Pr is a predetermined amount Th or more. If the deducted amount P-Pr is equal to or greater than the predetermined amount Th, the coupon is applied even after the product return request is received, and the discount amount D is deducted. Therefore, in the example shown in FIG. 6A, the return processing unit 134 refunds the total amount Pr of the product corresponding to the return request. If the return processing unit 134 determines that the deducted amount P-Pr is equal to or greater than the predetermined amount Th, the remaining discount amount is not updated.

In the return processing unit 134, when the deducted amount P-Pr is less than the predetermined amount Th and the deducted amount P-Pr is equal to or more than the discounted amount PD, that is, the discount amount D corresponds to the return request. If the amount is Pr or more, the return process is performed without refunding the amount Pr of the product. FIG. 6B shows an example when the deducted amount P-Pr is less than the predetermined amount Th and the discount amount D is equal to or more than the amount Pr corresponding to the return request. As shown in FIG. 6B, when the deducted amount P-Pr is less than the predetermined amount Th, the discount amount D of the coupon is not applied, and the payment amount of the user after the return is P-Pr. Will be. Since the discount amount D is equal to or greater than the amount Pr corresponding to the return request, the amount D-Pr obtained by subtracting the amount Pr corresponding to the return request from the discount amount D is the amount to be collected by the user. On the other hand, the return processing unit 134 allocates the amount D-Pr to the discount amount (residual discount amount) D of the coupon, and the user's payment amount is the same amount PD as the payment amount before the return (FIG. 6 (FIG. 6). b) Corresponds to the white circle in b), and processes the returned goods without refunding the amount of the product. The return processing unit 134 updates the remaining discount amount to D-Pr.

Further, the return processing unit 134 indicates that the deducted amount P-Pr is less than the predetermined amount Th and the deducted amount P-Pr is less than the discounted amount PD, that is, the discount amount D is the return request. If the amount is less than the corresponding amount Pr, the amount Pr-D obtained by subtracting the deducted amount P-Pr from the discounted amount P-D is refunded. FIG. 6C shows an example when the deducted amount P-Pr is less than the predetermined amount Th and the discount amount D is less than the amount Pr corresponding to the return request. As shown in FIG. 6 (c), when the deducted amount P-Pr is less than the predetermined amount Th, the discount amount D of the coupon is not applied, and the payment amount of the user after the return is P-Pr. Will be. Since the discount amount D is less than the amount Pr corresponding to the return request, the user's payment amount P-Pr after the return is lower than the amount P-D paid by the user before the return. Therefore, the return processing unit 134 performs a process of refunding to the user the amount Pr-D obtained by subtracting the user's payment amount P-Pr after the return from the amount P-D paid by the user before the return. The return processing unit 134 sets the remaining discount amount to 0.

In the example shown in FIG. 6, an example in which a return request is made once for one transaction is shown, but the return processing unit 134 may make a return request multiple times for one transaction. Similarly, the refund amount and the remaining discount amount are calculated.

When the return request receiving unit 133 receives the refund request, the return processing unit 134 indicates the transaction ID of the transaction corresponding to the return request, the return date and time, and the refund request amount and the refund amount indicating the amount of the product corresponding to the return request. , Is associated with the remaining discount amount, and is stored in the storage unit 12 as return history information.

In addition, the return processing unit 134 grants the coupon to the user when the amount of the product corresponding to the return request is applied to all the discount amount of the coupon by the return request and the remaining discount amount becomes 0. It may be possible to reuse it by such means. For example, the return processing unit 134 can delete the usage history of the coupon or reuse the coupon according to the fact that the amount of the product corresponding to the return request is applied to all the discount amounts of the coupon. The coupon is given by associating the reusable flag indicating the above with the coupon. Then, when the return processing unit 134 refunds the amount obtained by subtracting the discount amount from the amount of the product corresponding to the return request, the return request receiving unit 131 receives the payment request by reusing the coupon corresponding to the discount amount. You may do it. By doing so, the user can reuse the coupon.

When the return processing by the return processing unit 134 is completed, the notification unit 135 notifies the store terminal 2 of information indicating that the return processing is completed. The notification unit 135 notifies information indicating the reason why the return processing unit 134 does not refund a part or the whole amount of the goods when the return processing unit 134 does not refund the part or the whole amount of the goods. For example, the notification unit 135 indicates that a part or all of the amount of the product is applied to the discount amount of the coupon and the remaining discount amount is updated, and as a result, the part or all of the amount of the product is no longer refunded. Notify. As a result, the store clerk who uses the store terminal 2 can inform the user of the reason for not refunding a part or all of the amount of the product, and can suppress troubles at the time of return.

In addition, the notification unit 135 explains the reason why the return processing unit 134 does not refund a part or the whole amount of the product when the return processing by the return processing unit 134 is completed and the return processing unit 134 does not refund a part or the whole amount of the product. The information shown is notified, but it is not limited to this. For example, the notification unit 135 may receive the transaction ID and the amount of the product corresponding to the return request from the user terminal used by the user such as the mobile terminal at a timing different from the timing when the return request is made. Then, the notification unit 135 calculates the refund amount and the amount applied to the discount amount of the coupon based on the transaction ID and the amount of the product corresponding to the return request, as in the return processing unit 134, and outputs the calculation result to the user terminal. May be notified to. By doing so, it is possible to understand how much the return will be refunded before the user actually returns it.

Further, the notification unit 135 allocates the amount of the product corresponding to the return request to all the discount amounts of the coupon by the return request, and when the coupon is given to the user, the notification unit 135 is applied to the user terminal used by the user. You may want to notify that the coupon has been granted. By doing so, the user can recognize that the coupon has been given by the returned goods and can purchase another product or the like using the coupon.

[Flow of return processing in payment processing device 1]
Subsequently, the flow of the return processing in the payment processing device 1 will be described. FIG. 7 is a flowchart showing the flow of the return processing according to the present embodiment. The process according to this flowchart is started when the return request receiving unit 133 receives the refund request. The process according to this flowchart shows an example when the discount amount is a fixed amount.

First, the return processing unit 134 determines whether or not the deducted amount P-Pr obtained by subtracting the amount Pr of the product corresponding to the return request from the total amount P of the purchase amount is the predetermined amount Th or more (S1). .. When the return processing unit 134 determines that the deducted amount P-Pr is equal to or greater than the predetermined amount Th, the process is transferred to S3, and when it is determined that the deducted amount P-Pr is less than the predetermined amount Th, processing is performed in S2. Transfer.

In S2, the return processing unit 134 determines whether or not the deducted amount P-Pr is equal to or greater than the discounted amount PD. When the return processing unit 134 determines that the deducted amount P-Pr is equal to or greater than the discounted amount PD, the processing is transferred to S4, and when it is determined that the deducted amount P-Pr is not, the processing is transferred to S5.

In S3, the return processing unit 134 refunds the amount obtained by subtracting the discounted amount P-Pr-D after the return from the discounted amount PD, that is, the amount Pr of the product corresponding to the return request.
In S4, the return processing unit 134 processes the returned goods without refunding the amount Pr of the goods.
In S5, the return processing unit 134 performs a process of refunding to the user the amount Pr-D obtained by subtracting the user's payment amount P-Pr after the return from the amount P-D paid by the user before the return.

[Effects in this embodiment]
As described above, the payment processing device 1 according to the present embodiment accepts a return request for at least one of one or more products purchased in a transaction, and is a product corresponding to the return request from the total purchase price of the products. If the deducted amount, which is the amount after deducting the amount of the item, is less than the specified amount and the deducted amount is more than the discounted amount, the return is processed without refunding the amount of the item. By doing so, the payment processing device 1 can perform an appropriate return processing based on the conditions of the discount. Further, the user does not need to pay an additional purchase amount even when the coupon is not applied due to the return and the total amount of the purchase amount is less than the predetermined amount which is the application condition of the coupon. Also, the clerk does not need to explain to the user that the purchase amount will be additionally paid based on the fact that the coupon is no longer applied. Therefore, the payment processing device 1 can reduce the burden on the clerk and the user when returning the product.
