Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the drawings.

FIG. 1 shows a configuration of a conventional sine pad device, and FIG. 2 shows a configuration of a sine pad device having a tag function, which is an embodiment according to the present invention. FIG. 3 shows a procedure for transmitting and receiving information for each device according to the present invention. 4 shows a control method procedure of a sine pad device according to the present invention.

As shown in the figure, the most significant feature of the present invention is to provide a sine pad device used at an affiliate store with an NFC tag function, thereby providing users with various additional services using NFC. The initialization of the tag contents used by the user to read the basic information of the merchant is input using the payment terminal or using the ENF apparatus of the merchant. This basic information always initializes and stores the tag content after power-on of the sign pad device and after the specific service information is transmitted to the user mobile device. When the user simply tags the loop antenna 60 of the sine pad device to obtain information of the franchisee, basic information of the franchisee is transmitted to the user mobile device. When a user submits a card for payment, the payment terminal reads the card and performs the corresponding payment service. During the service process, the payment terminal sends a command to the sign pad device to request a signature input by the user, a password input, or a telephone number input. When the user inputs the information, the sign pad device processes the information and transmits the information to the payment terminal. When the payment terminal requests the transaction approval from the vendor and receives a message including the approval, the payment terminal transmits the NFC service information to the sign pad device if it confirms that the NFC service information of the corresponding service exists. The sign pad device stores the service information in the tag memory and then requests the tagging to the user. The user performs tagging and reads the service information to his / her mobile device. When the service information transmission is completed, the sign pad device initializes the tag memory as basic information again.

Referring to FIG. 2, the operation of a sine pad device supporting the multi-tag function according to the present invention will be described. The sine pad device having a multi-tag function includes a control section 10, a communication section 20, a display section 30, a touch section 40, an NFC connection section 50, a loop antenna 60, and a security module section 70 . Although the memory of the NFC connection unit 50 is used as the tag memory in this embodiment, the memory in the control unit 10 may be used in another embodiment.

The communication unit 20 is connected to the external payment terminal and is responsible for data transmission / reception of the sign pad device. The command received through the communication unit 20 is analyzed by the control unit 10 and output to the display unit 30 to wait for input of information such as a signature of the user. When the user inputs a signature or number information using the touch unit 40, the user encrypts the input user data and transmits the encrypted user data to the external payment terminal through the communication unit 20. [

When an external command is received via the communication unit 20, the control unit 10 analyzes the command to determine whether to display the command on the display unit 30 or the communication with the security module unit 70, It is judged whether or not to carry out the SF communication.

The communication unit 20 receives command data from an external device such as a payment terminal, sends the command data to the control unit 10, and receives response data as a result of the processing from the control unit 10 to the outside. As a data transmission / reception method, a universal serial communication (USB) method or a general serial communication (RS-232) method is used, and methods other than the above-mentioned methods such as wired LAN, wireless LAN, have.

The control unit 10 includes a CPU serving as a brain in the sine pad device, a flash memory for storing an execution program, and a data memory. The control unit 10 controls communication with the outside, , And performs memory and register control management in the control unit.

The NFC connection unit 50 is connected to the loop antenna 60 through a serial bus such as a UART / SPI / I2C to control communication with an ENF mobile device. The NFC connection unit 50 operates as a tag without generating an RF field like a reader. The NFC connection unit 50 is provided with an access circuit for communication with the control unit 10, a tag memory for storing information, And an analogue connection circuit that analyzes the on-data and transmits the data to the reader in response to load modulation.

The loop antenna 60 is connected to the NFC connection unit 50 and is used for wirelessly exchanging data with an NFC mobile device. In the method of transmitting data from the UE mobile device, the magnitude of the amplitude of the carrier is changed in the same manner as the speed of the data, and when receiving data from the tag, the weak modulation signal is detected in the sub- .

The security module unit 70 is connected to the control unit 10 and uses the encryption / decryption key, the encryption / decryption algorithm, and the secure storage of sensitive data to protect the communication data with the payment terminal or the communication data with the user mobile device And generally use contact smart cards.

FIG. 4 illustrates operation procedures of the payment terminal 300, the sine pad device 400, and the user mobile device 500, which are one embodiment of the present invention. The sine pad device stores basic information such as merchant information or announcement information in the tag memory while communication with the payment terminal is not performed (S401), and then waits for the user's tagging or receipt of an instruction from the payment terminal. When the user tags the sign pad device using the NF mobile device (S501), the sign pad device is recognized as a tag (S502) and the basic information is transmitted (S402). At this time, the user mobile device operates as a reader and the sine pad device operates as a tag. The user mobile device reads the basic information using the tag reading function and displays basic information on the screen of the mobile device (S502). After selecting the service function key from the payment terminal, the user card is read (S301), the amount is inputted (S302), the signature request command is sent to the sign pad device, and a response is awaited (S303). Upon receiving the signature request command, the sign pad apparatus displays a signature request on the display unit, and when the user completes the signature (S402), the sign pad apparatus processes the user signature data and transmits it to the payment terminal (S404). When the payment terminal receives the signature data, the payment terminal transmits the transaction special using wire communication or wireless communication to request the transaction approval request (S304). If the transaction approval is dropped, the payment terminal transmits the tag information of the service to the sign pad device (S305). The sine pad device stores the corresponding service tag information in the tag memory and requests the user for tagging (S404). When the user tags the mobile device (S504), the sign pad device is recognized as a tag (S505) and the service information in the tag memory is read (S405). The mobile device automatically executes the application of the service, and the service information is displayed on the screen (S506). The sign pad device informs the payment terminal of the result of the service information transmission (S406) and stores the basic information data again in the tag memory (S407).

5 is a flowchart illustrating a method of controlling a sine pad device according to the present invention. When power is applied to the sine pad device (S201), basic information is stored in the tag memory (S202). Here, the basic information means information transmitted to the user mobile device when the user tags the antenna portion of the SSP device while the user does not communicate with the payment terminal. For example, information such as merchant information, announcements, and the like. If the user does not request the signature of the user to proceed with the settlement service at step S203 and the user tags the sign pad device at step S204, the user mobile device operates as a reader and the sign pad device operates as a tag . The information in the tag memory is transmitted to the user mobile device using the tag reading function (S205). The sine pad device checks the completion of the tag data transmission (S206), and if there is data remaining, the tag data transmission is continued to transmit data to the user mobile device (S205). When the data transfer is completed, basic information is stored again in the tag memory (S202). When the payment terminal receives a signature request (S203), the sign pad device displays a signature request to the user through the display unit and waits for the signature (S207). If the user does not sign for a specific time, the timeout processing is performed (S212), the result is transmitted to the payment terminal (S213), and the basic information is stored again in the tag memory (S202). When the signature of the user is terminated (S208), the sign pad device processes the signature data, transmits the signature data to the payment terminal, and checks whether the tag service information exists (S209). If there is the tag service information (S210), the tag service information is stored in the tag memory from the payment terminal, and a message requesting the user to display the tag service is displayed on the display unit (S211). When the user tags the sign pad device (S204), the tag information is transmitted to the user mobile device using the tag reading function (S205). When the tag information data transmission is completed (S206), the sign pad device again stores the basic information in the tag memory (S202).

As described above, the sine pad device and the control method supporting the multi-tag function according to the present invention support the tag function of the conventional low-cost / simple-function sine pad device, so that there is no separate tag issuance for the merchant shop, But also to provide cost-effective and diverse customer service. In addition, the user can conveniently receive various services by using the NFC function.

The sine pad device and the control method supporting the tag function of the ENF makes it possible for the user to more easily use various additional services such as the merchant basic information transmission, the payment service, and the point / stamp service to the ENF mobile device, Can be used to reduce the economic cost due to the use of the tag.
