ABSTRACT:
The present invention provides radio frequency identification devices, remote communication devices, identification systems, communication methods, and identification methods. A radio frequency identification device according to one aspect includes a substrate; communication circuitry coupled with the substrate and configured to receive a wireless signal including an identifier, to process the identifier of the wireless signal and to output a control signal responsive to the processing of the identifier; and indication circuitry coupled with the communication circuitry and configured to receive the control signal and to indicate presence of the radio frequency identification device responsive to the control signal. A communication method according to another aspect includes providing a radio frequency identification device; receiving a wireless signal including an identifier within the radio frequency identification device; processing the identifier; generating a control signal after the processing; and indicating presence of the radio frequency identification device using indication circuitry of the radio frequency identification device responsive to the control signal.
