ABSTRACT:
An electronic tag has a processor, a readable memory for holding an identification number connected to the processor, and an antenna connected to the processor for radiofrequency broadcasting of the identification number. A power supply powers the antenna to broadcast the identification number.
A user selectively controls operation or non-operation of the electronic tag by switching an interconnect switch on or off. The interconnect switch permits interconnects the processor, readable memory, antenna, and power supply to selectively allow radiofrequency broadcasting of the identification number. Bitwise communication to a tag reader using only a passive electronic tag is possible.
