Patent ID: 8049624

Claim:
A wireless communication method in which a first wireless signal transmitted from a communication device is received by a plurality of semiconductor devices including at least a first semiconductor device and a second semiconductor device and thus a second wireless signal is transmitted to the communication device from the plurality of semiconductor devices, comprising: selectively switching a first state and a second state in the plurality of semiconductor devices including the first semiconductor device and the second semiconductor device in response to the first wireless signal transmitted from the communication device; and transmitting the second wireless signal including detection data indicating that the second wireless signal is received from the first semiconductor device in the first state to the communication device from the second semiconductor device in the second state, wherein the first state is a state in which the first wireless signal transmitted from the communication device is received, wherein the second state is a state in which the second wireless signal transmitted from the plurality of semiconductor devices is received, and wherein the communication device outputs a first instruction for transmitting data stored in the plurality of semiconductor devices to the communication device and a second instruction for selectively switching between the first state and the second state of the plurality of semiconductor devices.
