Short-range wireless communication refers to a wireless communication technology that transmits data between mobile terminals at low power at a certain distance, for example, 10 cm to several hundred meters. Near field communication is a variant of RFID that uses frequencies in the 13.56 MHz band and transmits data at a rate of 424 Kbits (424 Kbps) per second.

In addition, short-range wireless communication may be divided into a passive communication mode and an active communication mode. In the passive communication mode, an initiator forms an RF field and a target responds by applying a load modulation scheme to the command of the transmitter. On the other hand, in the active communication mode, both the transmitter and the target communicate by forming an RF field.
