Abstract
According to one embodiment of the present specification, an NFC device can comprise: a loop antenna disposed on a first surface of a substrate and transmitting and receiving a wireless signal, wherein an antenna area defined by the outer perimeter or the inner perimeter of the loop antenna is positioned within a first area on the first surface; at least one input interface disposed on the first surface of the substrate, wherein the input interface is positioned within a second area on the first surface, and the first area and the second area are different from each other; and a processor connected to the loop antenna and the input interface. when a user input for the input interface is detected in a communication mode in which the processor can communicate with the external NFC device, the processor can transmit, to an external NFC device through the loop antenna, an RF response signal including control information for executing a function corresponding to the input interface.
