Abstract: A near field communication (NFC) device includes a communications module and a controller. The communications module includes a receiver to receive a wireless signal, a transmitter to transmit data by superimposing the data on the wireless signal, and a signal detector to compare the wireless signal with a predetermined reference signal. The communications module operates in at least one of a wakeup mode and a sleep mode, the receiver and transmitter are activated to operate in wakeup mode, and the receiver and transmitter are deactivated in sleep mode. The controller adjusts the sensitivity of the signal detector based on a magnitude of the wireless signal and an operating condition of the communications module when the communications module enters the wakeup mode from the sleep mode.
