According to an embodiment of the present invention, the program 120 may transmit card touch guidance information for guiding the NFC-based card 200 to be effectively touched to a valid touch area on the rear side of the wireless terminal 100 corresponding to the model of the wireless terminal 100 It can be displayed in a certain area on the touch screen (605).

The program 120 sets (or confirms) a validity time including N time steps for validly receiving valid data of the NFC-based card 200 through the NFC module 110 and starts counting (610) . Preferably, the program 120 may display an interface screen for reading data of the NFC-based card 200 and may start counting the validity time while the NFC module 110 is in the read mode.

The program 120 counts each time step of the valid time and places the NFC-based card 200 in the valid touch area on the back of the wireless terminal 100 corresponding to the card touch area 300 displayed on the touch screen Based card 200 on the back side of the wireless terminal 100 is touched according to the touch information (and / or the card touch guide information) and valid data is received from the NFC-based card 200 at a close distance via the NFC module 110 (615).

If valid data is read from the proximity NFC-based card 200 through the NFC module 110 before the expiration time (and / or time step) elapses, the program 120 transmits the NFC- (Step 625), which uses the valid data read from the NFC-based card 200. [ If the counting of the valid time is not completed at the time of reading the valid data, the program 120 may terminate the counting of the valid time (620).

On the other hand, if valid data is not read from the NFC-based card 200 until each time step of the valid time elapses, the program 120 stores the valid time in the card touch area 300 displayed on the touch screen The emphasis event according to the elapsed time step is changed and displayed (625), and the process of reading valid data from the NFC-based card 200 while counting each time step can be repeated.

On the other hand, if the elapsed time elapses until the valid time elapses, the program 120 displays the maximum highlight event in the card touch area 300 displayed on the touch screen 630, The NFC-based card 200 is touched to the rear surface of the wireless terminal 100 corresponding to the area 300 and waits for valid data to be read from the proximity NFC-based card 200 through the NFC module 110 635). If the valid data is read from the NFC-based card 200 through the NFC module 110, the program 120 reads the valid data read from the NFC-based card 200 through the NFC module 110 (640). ≪ / RTI >

7 is a diagram illustrating a process of processing a touch input of a touch screen in a state that the card touch area 300 is displayed according to an embodiment of the present invention.

In more detail, FIG. 7 illustrates a case where the card touch area 300 displayed on the touch screen is overlapped with the designated touch area of the interface screen through the processes of FIGS. 4 to 6, A touch input process. Referring to FIG. 7, the touch input process may be performed by various methods (for example, a part of It is to be understood that the invention may be practiced otherwise than as specifically described herein, but it is to be understood that the invention is not limited to the disclosed embodiments, .

Referring to FIG. 7, a card touch area 300 corresponding to a model of the wireless terminal 100 is displayed in a superimposed manner on an interface screen on a touch screen and / The program 120 of the wireless terminal 100 displays the card touch guide information superimposed on the touch screen corresponding to the model of the wireless terminal 100 through the processes of FIGS. It is checked whether the touch area 300 (and / or the card touch guide information) overlaps with the M designated touch areas (or a part of the designated touch area) included in the interface screen displayed on the touch screen.

If the card touch area 300 (and / or the card touch guide information) corresponding to the model of the wireless terminal 100 is overlapped with the designated touch area of the interface screen, the program 120 is displayed on the touch screen It is checked whether a touch event occurs (705). If a touch event occurs through the touch screen, the program 120 determines whether the touch event is a touch event of a region corresponding to the designated touch region of the interface screen (710) When the touch event of the area corresponding to the area is confirmed, the program 120 processes the touch event generated through the touch screen as a touch input to the designated touch area of the interface screen (715) So that the touch input for the designated touch area included in the interface screen is effectively processed even when the card touch area 300 (and / or the card touch guide information) is displayed in a superposed state. According to the method of the present invention, the processes of FIGS. 4 to 6 are performed while the touch input process of FIG. 7 is performed.
