Figure 3 is a network-based flow chart for explaining the mobile credit settlement method for the merchant target by the unique call information of the present invention, the dotted line shows the wireless processing flow, the solid line shows the wired processing flow. In FIG. 3, reference numeral 100-1 may be, for example, a POS terminal having an ESNA function (hereinafter, referred to as an “ESNA POS terminal” in the description of FIG. 3) shown in FIG. 2. Reference numeral 200 represents a mobile communication terminal, 400 represents a banking system (which may be a bank or credit card company), and 300 is installed between the ESNA POS terminal 100-1 and the banking system 400 to authenticate the user. In addition, it represents an authentication / relay agency (hereinafter referred to as a 'FEM system' (Frequency Electronic Mobile system)) that performs the relay of transaction information. Meanwhile, the FEM system 300 stores various user information necessary for user authentication, that is, calling information, authentication password, and affiliated store identification information of a user mobile communication terminal 200 as a member. Therefore, in order to use the mobile credit settlement method of the user or affiliated member must register in advance in the FEM system 300, which will be described in detail later.

As shown in Fig. 3, the ESNA POS terminal 100-1 of the present invention emits a call signal at a predetermined period, for example, a period of 1.28 seconds (S1-1). In this state, when the user approaches his mobile communication terminal 200 to the ESNA-POS terminal 100-1 for a predetermined distance for credit settlement, the user's mobile communication terminal 200 in response to the call signal A frequency signal carrying unique call information is emitted (S1-2). Next, the ESNA POS terminal 100-1 receives the frequency signal emitted from the mobile communication terminal 200 in a reception standby state and analyzes the extracted call information (S2). Subsequently, after confirming the payment amount displayed on the display module 125, the user operates the key input unit 122 to input an authentication password (S2), and the ESNA POS terminal 100-1 inputs the call information extracted in step S2. The authentication password and the payment amount received are transmitted to the FEM system 300 to request a credit payment (S3). Next, the FEM system 300 receiving such a request performs user authentication based on the information provided in step S3, and if the authentication is allowed, the banking system 400 predetermined payment information (calling information, payment password, It may be payment account information, etc., may be other information) and the payment amount is requested to make a credit payment (S4).

Next, the banking system 400 receiving such a request determines whether to make a credit payment by its own financial service, and then transfers the determined result to the FEM system 300 (S5). Thereafter, the FEM system 300 transfers the payment result received from the banking system 400 to the ESNA POS terminal 100-1, and the ESNA POS terminal 100-1 outputs a sales slip based on the credit settlement process. Will end. In the banking system 400, if the credit approval result is wirelessly transmitted to the user's mobile communication terminal 200 by SMS, the user's reliability may be further improved. Although the above has described credit settlement, it is possible to perform debit payment (corresponding to a conventional debit card payment) by the same flow.

On the other hand, since the radio frequency signal emitted from the mobile communication terminal has a property of spreading to a wide space, a method of accurately recognizing a mobile communication terminal from another terminal may be an important problem. First, the ESNA 100 In order to receive the frequency signals from all the mobile communication terminal around the ESNA 100 by increasing the reception sensitivity of the user, and to confirm the mobile communication terminal of the user who is the subject of the transaction, predetermined information from the user, for example, the last four digits of the MIN information. There may be a way to receive input (the more digits entered, the higher the accuracy of the check). In this case, if the back digits of the MIN information and the authentication password are input consecutively, the inconvenience to the user may be reduced.

Secondly, the method of lowering the reception sensitivity of the ESNA 100 to accept only a frequency signal of a mobile communication terminal approached within a predetermined distance from the ESNA 100, for example, within 10 [cm], preferably almost in contact, There may be. In order to further improve the accuracy of confirmation, there may be a method of putting the mobile communication terminal into an electromagnetic shielding space and processing only inserting and processing an antenna unit of the mobile communication terminal to which the frequency signal is radiated.

Demonstrate that useful information can be extracted.

FIG. 5 is a network-based flow chart for explaining a mobile financial transaction method for a CD / ATM target using unique call information of the present invention. The dotted line represents a wireless processing flow, and the solid line represents a wired processing flow. In FIG. 5, reference numeral 100-2 may be, for example, a CD / ATM having an ESNA function (hereinafter referred to as 'ESNA CD / ATM' in the description of FIG. 5) shown in FIG. Denotes a mobile terminal, 400 denotes a banking system (which may be a bank or credit card company), and 300 denotes a user authentication or transaction information intervening in the ESNA CD / ATM 100-2 and the banking system 400. Represents a FEM system that performs relaying.

Meanwhile, the FEM system 300 stores various user information necessary for authentication, that is, call information, authentication password, and payment account information of a user mobile communication terminal 200, which is a member, in a database. Therefore, in order for a user to use the mobile financial transaction method, a member must be registered in advance in the FEM system 300, which will be described in detail later.

As shown in Fig. 5, the ESNA CD / ATM 100-2 of the present invention emits a call signal at a predetermined period, for example, a period of 1.28 seconds (S11-1). In this state, when a user who is a member approaches his / her mobile communication terminal 200 to the ESNA CD / ATM 100-2 in order to receive financial transaction services such as cash in / out, withdrawal, or transaction history inquiry, In response to the call signal, the user's mobile communication terminal 200 emits a frequency signal carrying unique call information (S11-2). Next, the ESNA CD / ATM 100-2 receives and analyzes the frequency signal emitted from the mobile communication terminal 200 in the reception standby state and extracts call information (S12). Subsequently, the user operates the key input unit 122 of the ESNA CD / ATM 100-2 to input an authentication password (S12).

Next, the ESNA CD / ATM 100-2 transmits the call information extracted in step S12 and the input authentication password to the FEM system 300 to request user authentication according to a financial transaction (S13). Subsequently, the FEM system 300 inquires its own database based on the information provided in step S13, extracts user authentication and payment account information, and if the authentication is allowed, corresponds to the ESNA CD / ATM 100-2. The payment account information of the user is notified (S14).

The above process corresponds to a process in which a CD / ATM reads a user's credit card, extracts payment account information, receives a password from the user, and authenticates a user in a conventional financial transaction method using a credit card. The financial transaction service provided by the conventional CD / ATM can be provided. For example, in the case of selecting the cash service function, the ESNA CD / ATM 100-2 displays account transaction information such as call information, service number, payment account number, account password and withdrawal amount. 400, and the banking system 400 approves the payment to the ESNA CD / ATM 100-2 (S15) so that the cash is withdrawn. Meanwhile, in this process, the banking system 400 may increase the user's convenience by transmitting the approval result to the mobile communication terminal 200 of the user through SMS (S16).

Figure 6 is a network-based flow chart for explaining the mobile electronic money purchase and payment method according to the unique call information of the present invention, the dotted line represents the wireless processing flow, the solid line represents the wired processing flow. In FIG. 6, reference numeral 100-3 may be, for example, a POS terminal of an affiliated store capable of using electronic money with an ESNA function (hereinafter, referred to as an “ESNA POS terminal” in FIG. 6). , Reference numeral 200 denotes a mobile communication terminal, 400 denotes a banking system (which may be a bank or credit card company), 500 denotes an electronic money purchasing server, and 300 denotes an ESNA POS terminal 100-3 and electronics. The FEM system intervenes in the currency purchase server 500 to perform user authentication or relay of transaction information.

Meanwhile, the FEM system 300 stores various user information necessary for user authentication, that is, a call number of the user mobile communication terminal 200 as a member, electronic money balance information, and identification information of an affiliated store in its database. Therefore, in order to use the mobile electronic money purchase and payment method of the user or merchant, the member must be registered in advance in the FEM system 300, which will be described in detail later.

As shown in FIG. 6, in order to purchase electronic money, the user must access the homepage of the electronic money purchase server 500 through the wireless Internet and make an electronic money purchase request (S21). The electronic money purchase server 500 In step S22, the call information of the mobile communication terminal 200 extracted at the time of wireless internet connection is transferred to the FEM system 300 to confirm whether the corresponding user has subscribed. Next, the FEM system 300 checks its own database and confirms whether the user subscribes, and then transfers the result to the electronic money purchase server 500 (S23). Next, the electronic money purchase server 500 requests the payment to the corresponding banking system 400 according to the payment method, for example, account transfer or credit payment, which the user inputs on the purchase page when the user requests a purchase (S24). Subsequently, the banking system 400 performs the requested payment process and notifies the result of the electronic money purchase server 500 to the electronic money purchase server 500 (S25), and the electronic money purchase server 500 sends the electronic money purchase information, that is, the amount information, to the FEM system. Delivered to the storage 300 (S26), which corresponds to the electronic money purchase process.

Meanwhile, the user may use his client PC (not shown) to access the electronic money purchase server 500 through the wired Internet.

Next, a process for the user who purchased the electronic money to use the same will be described. In the ESNA POS terminal 100-3, as described above, the call signal is emitted at a predetermined period, for example, a period of 1.28 seconds (S27). -1) In this state, when the user approaches his mobile communication terminal 200 to the ESNA-POS terminal 100-3 for a predetermined distance to pay electronic money, the user's mobile communication terminal 200 responds to such a call signal. As a result, a frequency signal carrying unique call information is emitted (S27-2). Next, the ESNA POS terminal 100-3 receives the frequency signal emitted from the mobile communication terminal 200 in the reception standby state and analyzes the extracted call information (S28).

Next, the user transmits the call information and the payment amount extracted in step S28 to the FEM system 300 to request the electronic money payment (S29). Subsequently, the FEM system 300 receiving such a request inquires its own database based on the received call information, inquires the user authentication and the electronic money balance of the user, and permits authentication and, if the balance is sufficient, ESNA POS. The electronic money is paid to the terminal 100-3 (S30).

As described above, the electronic money purchase and payment method of the present invention is similar to the conventional debit card payment method, and is omitted for authentication because it is only used for small payments. However, if the amount is a high amount, the security may be further enhanced by receiving an authentication password as in the credit settlement method of FIG. 3.

FIG. 7 is a network-based flow chart illustrating a method of paying a traffic fare based on unique call information of the present invention, wherein a dotted line represents a wireless processing flow and a solid line represents a wired processing flow. In FIG. 7, reference numeral 100-4 denotes, for example, a traffic terminal having an ESNA function (hereinafter, referred to as an “ESNA bus terminal” in the description of FIG. 7) shown in FIG. 2, and 200 denotes a mobile communication terminal. 400 denotes a banking system (which may be a bank or credit card company), 600 denotes a bus system, and 300 denotes a banking system 400 and a bus system 600 to perform user authentication or transaction information relay. Represents a FEM system.

As shown in Fig. 7, the ESNA bus terminal 100-4 emits a call signal at a predetermined period, for example, a period of 1.28 seconds, as described above (S41-1). In this state, when a user who is a member approaches his mobile communication terminal 200 to the ESNA bus terminal 100-4 by a predetermined distance for payment of a bus fee, the user's mobile communication terminal 200 calls such a call signal. In response, a frequency signal carrying unique call information is emitted (S41-2). Next, the ESNA bus terminal 100-4 receives the frequency signal emitted from the mobile communication terminal 200 in the standby state of reception, analyzes and extracts call information (S28), and stores the call information in its own memory together with the payment amount. Temporarily store (S42). Since the process is almost the same as the conventional card-type fare payment flow, when the bus is over, the driver removes the ESNA bus terminal 100-4, connects it to the bus system 600, and stores the call information stored in the memory. The payment amount is transferred to the database of the bus system 600 (S43).

Next, the bus system 600 transmits and stores the collected payment information to the FEM system 300 at predetermined cycle units, for example, a predetermined cycle of daily unit, weekly unit or monthly unit, and requests settlement (S44). The FEM system 300 receives such a request and then transfers the provided information to the banking system 400 to request a settlement (S45). Subsequently, the banking system 400 transmits the settlement processing result and the call information of the mobile communication terminal in which the loss report is received (S46), and the FEM system 300 receives the settlement processing result and the lost information. To the bus system (S47).

Subsequently, the bus system 600 transfers the call information of the mobile communication terminal in which the loss report is received to the ESNA bus terminal 100-4 to the ESNA bus terminal 100-4 and stores the stored information (S48). Do not allow payment to the terminal. Finally, the banking system 600 bills the bus fee for the user of the mobile communication terminal 200 in a postpaid manner (S49).

Of course, by slightly modifying the above-described embodiment, the ESNA bus terminal 100-4 transmits the call information temporarily stored in step S42 to the bus system 600 via a WLAN or the like and receives a lost report. Inquiry whether the terminal in real time, the bus system 600 confirms whether the mobile communication terminal is a mobile communication terminal that received the loss report based on the received call information, and also the result through a WLAN or the like. It may be to inform the ESNA bus terminal 100-4 in real time, which may further increase the reliability of the transaction.

As described above, according to the traffic fare payment method of the present invention, the convenience of the user can be improved by processing the payment of the relatively small traffic fare without an authentication process. In addition, the method of payment of transportation fees can be applied to the method of payment of transportation fees of trains or railways. For example, ESNA 100 may be additionally added to existing transportation terminals installed at entrances and exits of trains or railway stations. After the installation and change of the bus system to the train system or the railway system, the traffic fare payment can be performed by the processing flow of FIG. In this case, since the ESNA traffic terminal is fixedly installed at the entrance / exit of the train station or the railway station, the ESNA traffic terminal does not need a separate memory, and the FEM system 300 handles the charge processing such as an authentication service for the ESNA traffic terminal. Can act as a gateway to perform.
