1 is a configuration diagram schematically showing the entire system for a coupon transaction service that prevents double use according to an embodiment of the present invention, and FIG. 2 shows the configuration of a transaction service system according to an embodiment of the present invention. It is a function block diagram.

1 and 2, the entire system includes a transferor terminal 10, a transferee terminal 20, and a transaction service system 30, and the transaction service system 30 includes a communication unit 210 and a storage unit 220. ) and a control unit 230, but the control unit 230 may include an interface unit that can be implemented in software or hardware, an authentication unit, and a payment/settlement unit.

The transferor terminal 10 and the transferee terminal 20 are terminal devices each possessed by the transferor and the transferee who transact coupons, and are, for example, computing devices equipped with communication functions such as PCs and smart phones.

The transaction service system 30 provides a transaction service for transferring electronic coupons possessed by the transferor to the transferee, and in particular, provides a double-use prevention service so that only the transferee can normally use the coupon.

The communication unit 210 of the transaction service system 30 is a communication means for communicating with the transferor terminal 10 and the transferee terminal 20 through a communication network, and since this will be obvious to those skilled in the art, a detailed description thereof will be omitted.

The storage unit 220 stores information about the coupon (serial number, etc.) and holder information (terminal information, such as phone number, MAC address, etc.) of the corresponding coupon. In addition, information necessary for the transaction service system 30 to provide a coupon transaction service for preventing double use may be further stored in the storage unit 220, which will become more apparent to those skilled in the art through the following description.

The interface unit 231 of the control unit 230 provides the transferor terminal 10 with a user interface screen (see FIG. 3 ) for transfer transactions for coupons owned by the transferor. The user interface will be described in detail later.

When a request for use of a coupon for which a transfer transaction is received is received, the authentication unit 232 processes holder authentication with the transferee terminal 20 according to the terminal information of the transferee received from the transferor terminal 10 . For example, the transferee terminal 20 informs that the coupon is currently being used (using an application program installed in the transferee terminal 20 or sending a message including an authentication number, etc.), and confirming normal use from the transferee terminal 20 Authentication succeeds if the information is received.

According to another example for more secure holder authentication using an authentication key, the transaction service system 30 transmits an authentication key program for generating an authentication key that changes according to time to the transferee terminal 20, and Holder authentication may be processed by receiving and authenticating an authentication key. It goes without saying that various authentication methods can be used for holder authentication.

The payment/settlement unit 233 processes the payment to the transferee for the payment amount (transaction amount) according to the coupon transfer transaction, and settles the settled amount to the transferor. Of course, if there is a transaction fee, a part of the payment amount may be settled as a fee.

3 is a flowchart illustrating a coupon transaction service process for preventing double use according to an embodiment of the present invention, and FIG. 4 is a user interface screen provided to a transferor terminal for coupon transaction according to an embodiment of the present invention. It is the flow chart shown.

Referring to FIG. 3 , the transaction service system 30 provides the transferor terminal 10 with a user interface screen for a transfer transaction for a coupon possessed by the transferor.

Referring to FIG. 4 together, information on coupons held by the transferor terminal 10 is provided, and interfaces such as buttons for transactions such as gift giving are provided. When making a transaction, the transferee information, such as the transferee's name and phone number, must be entered.

Referring back to FIG. 3 , a transfer request for a coupon is received through the user interface screen, and at this time, transferee terminal information is received from the transferor terminal 10 (S320).

Then, the transferee terminal information is stored, and a coupon is provided to the transferee terminal 20 according to the transferee terminal information (S330). For example, a message notifying that a coupon has arrived is transmitted to the transferee terminal 20, and information enabling access to a view page by an application program or a URL displaying an interface screen where the corresponding coupon can be used is provided.

When the corresponding coupon is used later, holder authentication is processed by the transferee terminal 20, and use of the coupon is normally permitted only when authentication is successful (S340).

Here, although not shown in the drawing, the transaction service system 30 records history information (transaction date and time, transferor/transferee information, etc.) according to the transfer transaction in the coupon. For example, the history information may be recorded on the coupon itself so that the transferee can recognize it, and it may be recorded in the storage unit 220 of the transaction service system 30 as tag information on the corresponding coupon.

According to an example, when a coupon is used later (actual use or transfer to another person), use information may be provided to the transferor terminal 10 by referring to the history information. For example, a message such as [the transferee used the coupon normally] or [the transferee transferred the coupon to another person] is transmitted to the transferor terminal 10 using SMS or the like.

5 is a flowchart illustrating a process of searching for and processing coupons stored in the transferor's terminal 10 for preventing double use according to an embodiment of the present invention.

Referring to FIG. 5 , when the transaction is completed, the transaction service system 30 searches for coupons stored in the transferor's terminal 10 (S510). That is, it is searched for whether the transaction completed coupon is stored in the form of a file such as an image or PDF in the transferor terminal 10 . This may utilize a related application program installed in the transferor's terminal 10 .

As a result of the search, it is determined whether a transferred coupon exists (S520), and if the searched coupon exists, the corresponding coupon is deleted or changed to an unusable state (for example, serial number, barcode, etc. are deleted) (S530) .

In contrast, if the corresponding coupon does not exist, this process may end.

According to this embodiment, it is possible to fundamentally block double use by disabling the use of coupons pre-stored in the transferor's terminal 10 .

6 is a flowchart illustrating a transfer transaction safe settlement cost settlement process according to an embodiment of the present invention.

Referring to FIG. 6 , the transfer amount (transaction amount, fee, etc.) is paid to the transferee (S610). All online payment methods such as credit card payment and transfer payment can be used.

The coupon transaction amount may be settled directly to the transferor for the payment processed amount, but according to the present embodiment for safe transaction, the transaction amount may be settled to the transferor after the transferee normally uses the coupon.

According to this example, the transaction service system 30 checks the time that has elapsed since the transaction when using the transferred coupon (S620). For example, if the transaction was processed on December 1, 2022 and the usage date is December 16, 2022, the elapsed time would be 15 days.

The payment amount is finally settled by applying the fee according to the confirmed elapsed time (S630). That is, after using the coupon, the coupon transfer cost is settled to the transferor, and the transaction fee is also settled at this time. For example, the longer the elapsed time, the higher the fee may be set. According to an example, a basic transaction fee of 1,000 won may be processed first, and a portion of the fee may be returned in a larger amount or paid as points as the elapsed time is shorter.

According to this embodiment, after using the coupon for the payment amount, the transferor is settled to secure a safe transaction, but benefits are provided to the transferee to induce faster use of the coupon, so that the transferor can be quickly settled.

A computer program stored in a computer-readable medium may be provided to perform the coupon transaction service method for preventing double use according to the present invention described above.

In addition, the above-described coupon transaction service method for preventing double use can be implemented as computer readable code on a computer readable recording medium. Computer-readable recording media includes all types of recording media in which data that can be decoded by a computer system is stored. For example, there may be read only memory (ROM), random access memory (RAM), magnetic tape, magnetic disk, flash memory, optical data storage device, and the like. In addition, the computer-readable recording medium may be distributed to computer systems connected through a computer communication network, and stored and executed as readable codes in a distributed manner.

In addition, although the above has been described with reference to preferred embodiments of the present invention, those skilled in the art can make the present invention within the scope not departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that various modifications and variations may be made.
