    Abstract: A passive wireless tag to identify a given command which has been received, even while responding to a wireless tag communication device. In this wireless tag, radio waves serving as a predetermined command are received from a wireless tag communication device via an antenna and an RF switch. Signal components are detected from the received radio waves by the detection circuit. The detected signal components are sampled by the sampling circuit in accordance with the timing when the RF switch is controlled to its ON state by a predetermined control signal. The time interval of the ON state is set to be sufficiently shorter than a transfer cycle of the received radio waves. The control circuit thus identifies the foregoing predetermined command according to the sampling results obtained from the sampling circuit.
