1 is a system configuration diagram showing a prepaid card issuing system according to an embodiment of the present invention.

As shown in FIG. 1, the prepaid card issuing system 10 includes a management server 100 connected to the prepaid card issuing terminal 110 through at least one prepaid card issuing terminal 110 and a communication network 120. It is made to include.

The communication network 120 broadly includes a communication network that enables data communication between the prepaid card issuing terminal 110 and the management server 100. However, in the first embodiment, the PSTN network can reduce the restrictions on the place where the prepaid card issuing terminal 110 is installed. However, the PSTN network alone is not limited to the type of the communication network.

Looking at a simple example the procedure for issuing a prepaid card by the prepaid card issuing system 10 as follows.

In this example, a customer purchases a prepaid card with a par value of 10,000 won of a specific prepaid card issuer (A company) through the prepaid card issuing system 10.

First, the customer 160 visits a retailer where the prepaid card issuing terminal 110 is installed, and pays the purchase amount while displaying the intention of purchasing a prepaid card for 10,000 won bills of A company (161).

At this time, the prepaid card issuing terminal 110 of the dealer closes the RF information unit of the prepaid card issuing terminal 110 with the product information RF card 130 containing information for issuing the A company's gold 10,000 won prepaid card. By activating the prepaid card issuance process.

The prepaid card issuing terminal 110 generates a first identification number request message corresponding to the information transmitted from the product information RF card 130 and transmits it to the management server 100 through the communication network 120.

The management server 100 returns a first identification number response message including the first identification number and the encryption key in response to the first identification number request message received from the prepaid card issuing terminal 110.

When the prepaid card issuing terminal 110 receives the response message, the prepaid card issuing terminal 110 encrypts the first identification number with the encryption key based on the first identification number and the encryption key included in the received response message. 2 Create an identification number.

The prepaid card issuing terminal 110 transmits the authentication request message for the second identification number to the management server 100.

The management server 100 transmits the authentication request message to the prepaid card issuer server 151 again, and receives the authentication success message from the prepaid card issuer server 151 in response to the authentication request message. Return to the issuing terminal 110.

When the prepaid card issuing terminal 110 receives the authentication success message, the customer 160 outputs a paper receipt 140 including the second identification number of the prepaid card through the printing unit of the prepaid card issuing terminal 110. You will be issued a prepaid card.

In addition, the prepaid card issuing terminal 110 outputs the paper receipt 140 and updates the issuance limit information about the seller of the prepaid card issuing terminal 110 in the sales information management unit in the prepaid card issuing terminal 110. do. In other words, after the procedure for issuing the prepaid card is completed, the sales deposit deposited by the seller shall be the initial issuance limit, and the balance remaining after subtracting the prepaid card face value from the previous issuance limit is updated to the new issuance limit. This will allow you to issue more prepaid cards as much as your limit.

2 is a block diagram showing in more detail the configuration of a prepaid card issuing terminal according to a first embodiment of the present invention.

As shown in FIG. 2, the prepaid card issuing terminal according to the first embodiment of the present invention includes an RF reader 310, a communication interface 320, an identification number manager 330, a sales information manager 340, It includes a printing unit 350 and the control unit 360.

First, the RF reader 310 reads the product information RF card 130 to be issued and receives information on the winding type and face value of the prepaid card held by the product information RF card 130. The received information about the paper type and face value of the prepaid card is transmitted to the controller 360, and the prepaid card issuing procedure is activated based on the information.

In this case, the RF reading unit 310 may be widely applied as long as the RF card reading means capable of reading a general contactless RF card. In particular, the RF reading unit of the prepaid card issuing terminal according to the present invention uses the RF reading means included in the so-called traffic card charging terminal used to charge a contactless prepaid traffic card issued or distributed by a traffic card company such as Korea Smart Card Co., Ltd. It is also possible to utilize as 310.

The communication interface 320 is responsible for data communication with the management server. Through the communication interface 320, the prepaid card issuing terminal 110 transmits the full text generated by the control unit 360 to the management server in the process of issuing the prepaid card, or transmits the full text received from the management server to the control unit 360. To pass).

The identification number management unit 330 generates a second identification number by encrypting the first identification number with an encryption key based on the first identification number and the encryption key received from the management server.

In the prepaid card issuing system according to the prior art, when receiving an identification number from a server performing a role corresponding to the management server of the present invention, by adopting a method of printing the received identification number in the paper receipt as it is, In case of leaking to a third party, there is a problem of being exposed to the risk of theft of the leaked identification number.

In contrast, in the prepaid card issuing terminal and the prepaid card issuing system according to the present invention, instead of using the identification number received from the management server, that is, the first identification number as the identification number of the prepaid card, it is received together with the first identification number. The second identification number is generated by the prepaid card issuing terminal itself based on the encryption key, and then the second identification number is printed on the paper receipt.

That is, since the second identification number cannot be leaked to an external third party until the second identification number is generated through the first identification number and the encryption key in the prepaid card issuing terminal 110, the risk of theft due to the identification number leakage is fundamental. You can block. In addition, since the encryption key is also shared in the management server, after the identification number management unit 330 generates the second identification number, the prepaid card issuing terminal 110 generates an authentication request for the generated second identification number management server. In the request, the management server decrypts the second identification number with a shared encryption key so that the management server can authenticate whether the first identification number before encryption is matched. According to the embodiment, instead of directly decoding the second identification number, the management server may receive a decoding result of the second identification number from the issuer server for the prepaid card.

The sales information management unit 340 is responsible for managing and updating the prepaid card issuance limit of the prepaid card issuing terminal 110.

Since the prepaid card is a kind of securities, there is a concern that an operation problem may occur when the prepaid card is issued unlimitedly in the prepaid card issuing terminal 110. Therefore, there is a realistic need to limit the issuance value of prepaid cards to a certain limit or less.

Accordingly, the prepaid card issuing terminal 110 according to the present invention is a pre-paid card face value issued by deducting the amount of the prepaid card face value currently issued from the previous issuance limit, using the sales deposit paid by the prepaid card seller to the prepaid card distribution company as the initial issuance limit. Update the balance to the new issue limit.

To this end, the prepaid card issuing terminal 110 according to the present invention receives the sales deposit information from the management server and stores it in the sales information management unit 340. In addition, the sales information management unit 340 updates the prepaid card issuance limit for each prepaid card issuance.

At this time, the sales information management unit 340 may store an identification code for identifying a seller of the corresponding prepaid card issuing terminal 110, for example, a seller ID, and store sales deposit information received from the management server for the seller ID. . This sale deposit is the initial issuance limit of the prepaid card issuing terminal 110.

The printing unit 350 prints a paper receipt including the paper type, the issue value, and the second identification number of the prepaid card to be issued, so that the customer can finally receive the prepaid card to purchase.

3 is an exemplary view showing an example of a prepaid card issued by a printing unit.

As shown in FIG. 3, the prepaid card 400 in the form of a paper receipt issued by the printing unit essentially includes the book type 410, the issue price 411, and the second identification number 412 of the prepaid card.

In addition, depending on the nature of the prepaid card and the needs of the prepaid card, the store name (413), the store's business registration number (414), the store's phone number (415), the prepaid card issuer name (416), and the prepaid card issuing terminal Fields related to items such as number 417, prepaid card issue date and time 418, prepaid card expiration date 419, usage guide 420, and other guide 421 may be further included.

2 again, the controller 360 will be described.

The controller 360 controls the overall operation of the prepaid card issuing terminal 110. To this end, the controller 360 drives a firmware program that controls the operation of each component of the prepaid card issuing terminal 110. In addition, the controller 360 may also generate various full texts transmitted to the management server or decrypt the various full texts received from the management server.

Figure 4 is a block diagram showing a prepaid card issuing system according to another embodiment of the present invention.

In the prepaid card issuing system 10 ′ according to another embodiment of the present invention, the prepaid card issuing terminal 110a is a portion 111 responsible for RF reading and a portion responsible for outputting a prepaid card as shown in FIG. It may be in the form (110a) including 112.

Unlike the prepaid card issuing terminal 110 of FIG. 1 in the form of an integrated device, the prepaid card issuing terminal 110a of the form shown in FIG. 4 is an RF traffic card charging terminal connected to the POS device 112 of a convenience store ( In this case, the prepaid card issuing system according to the present invention is implemented.

In this case, the POS server 101 jurisdiction of the POS device 112 of the convenience store should be further connected to the system, but the POS server 101 simply transfers the full text between the prepaid card issuing terminal 110a and the management server 100. It just serves.

In addition, the same reference numerals are assigned to components that perform the same functions as in FIG. 1.

5 is a flowchart illustrating a flow of a prepaid card issuing method according to an embodiment of the present invention.

As shown in Figure 5, the prepaid card issuing method according to an embodiment of the present invention, issuing request step (S100), the first identification number receiving step (S110), the second identification number generation step (S120), Issuance limit update step (S130) and prepaid card printing step (S140) is made.

First, look at the issue request step (S100) in detail.

If there is a request for issuing a prepaid card of the customer 500, the wireless card communicates with the goods information RF card through the RF reader of the prepaid card issuing terminal 510, and the prepaid card held by the goods information RF card to be issued. Receive information about the denomination and face value (S101).

Next, the controller of the prepaid card issuing terminal 510 generates a first identification number request message requesting a first identification number required for issuing the prepaid card based on the product information (S103).

The generated first identification number request message is transmitted to the management server 520 through the communication interface unit (S105).

Next, the first identification number receiving step (S110) will be described.

In this step, the prepaid card issuing terminal receives the first identification number from the management server (S111). The first identification number is included in the first identification number response message transmitted from the management server to the prepaid card issuing terminal as a response to the prepaid card issuing request message.

On the other hand, in the first identification number response message, an encryption key for transmitting the prepaid card issuing terminal to generate the second identification number by encrypting the first identification number is transmitted together with the first identification number.

Next, look at the second identification number generation step (S120) in detail.

In the second identification number generation step (S120), first, the first identification number and the encryption key received from the management server 520 are extracted by the control unit of the prepaid card issuing terminal 510 (S121).

Thereafter, the first identification number is encrypted with the encryption key by the identification number management unit to generate a second identification number (S123).

The prepaid card number listed on the paper receipt and shown to the general customer is the second identification number. Since the second identification number is generated in the prepaid card issuing terminal only in the second identification number generation step (S120), the pre-paid card is basically blocked because the identification number is leaked to a third party in advance.

Next, in the issuance limit update step (S130), the prepaid card issuance limit of the corresponding prepaid card issuing terminal managed by the sales information management unit of the prepaid card issuing terminal is updated.

As described above with reference to FIG. 2, the sales information management unit of the prepaid card issuing terminal sets the sales deposit of the prepaid card issuing terminal as the initial issuance limit, and each time the prepaid card sales procedure is performed, The procedure to update the difference in the face value of the prepaid card in the procedure to the new issuance limit.

The information on the sales deposit is transmitted to the prepaid card issuing terminal from the management server by a separate procedure and then stored in the sales information management unit. Such a sales deposit setting procedure may be performed periodically or aperiodically in some cases. .

Next, in the prepaid card printing step (S140), a procedure of printing information necessary for the prepaid card in the form of a paper receipt is performed so that the customer can actually receive the prepaid card information.

To this end, in the prepaid card printing step (S140), the data to be printed on the paper receipt from the control unit of the prepaid card issuing terminal is transmitted to the printing unit, and the printing job is performed through an appropriate printing device of the printing unit. If the printing apparatus is a prepaid card information can be well represented on the paper receipt, a printing apparatus of various printing methods can be widely applied regardless of the printing method such as a thermal printer, a laser printer, an inkjet printer.

6 is a flowchart illustrating a procedure further including a second identification number authentication step after the second identification number generation step according to another embodiment of the present invention.

After the second identification number generation step S120, a modified embodiment of the form further includes a second identification number authentication step.

As shown in FIG. 6, the prepaid card issuing terminal 510 may generate a second identification number, and then request authentication from the management server 520 regarding an error of the generated second identification number.

To this end, the controller of the prepaid card issuing terminal 510 generates a second identification number authentication request message (S151), and transmits the second identification number authentication request message to the management server 520 through the communication interface unit (S153). .

When the management server 520 receives the second identification number authentication request message, it delivers it to the prepaid card issuer side server 530 in real time. When receiving the authentication response message containing the authentication result from the prepaid card issuer server 530, the management server transmits the authentication response message back to the prepaid card issuing system. The prepaid card issuing server side 530 encrypts the first identification number stored in the prepaid card issuing server side 530 independently using the same encryption key transmitted to the prepaid card issuing system. If the encrypted result matches the second identification number transmitted from the management server 520, the second identification number is successfully encrypted without error.

The prepaid card issuer side server 530 generates a second identification number response message including the authentication result information regarding the second identification number and returns the reply to the management server, and when the management server transmits it to the prepaid card issuing terminal 510. Prepaid card issuing terminal receives the corresponding message (S155). Based on the authentication result information included in the second identification number response message, the prepaid card issuing terminal 510 may determine whether the second identification number is properly generated.

On the other hand, before and after the prepaid card printing step (S140) may further comprise the step of notifying the management server side in real time the results of issuing the prepaid card.
