Abstract (en)
[origin: WO0052636A2] An electronic tag is provided which includes processor means and transmitter circuitry. The processor means, which is typically a micro-controller, is programmed to provide a modulation control signal which includes unique identification data which at least identifies the tag but may include further data. The transmitter circuitry is connected to the processor means and to an antenna for transmission of the unique identification data. The transmitter circuitry is powered by the modulation control signal. Preferably, the transmitter circuitry is exclusively powered by the modulation control signal of the processor means. The invention extends to a receiver for receiving a transmission from the tag and to a system including a plurality of receivers and tags. The invention also extends to a method of communicating data from an electronic tag which includes driving transmitter circuitry of the tag with a modulation control signal which substantially powers the transmitter circuitry.
