Abstract
An operation mode switching module for a switching a near-field communication device between a sleep mode and a communication mode is provided. The operation mode switching module includes a driver, a detector, and a state machine. The driver drives a resonant circuit to generate an oscillation signal. The detector detects a level of effect of the environment upon the oscillation signal. The state machine determines whether to switch the near-field communication device from the sleep mode to the communication mode according to the level of effect of the environment upon the oscillation signal.
