PASSIVE TRANSPONDER IDENTIFICATION APPARATUS

摘要

A passive transponder identification apparatus which includes a plurality of transponders, a microprocessor and a single reader/transmitter coupled to the microprocessor. A plurality of antennas are provided with each antenna being coupled via a signal relay with the microprocessor. Each one of the plurality of antennas is dedicated to one of the plurality of transponders. The microprocessor sequentially activates each one of the plurality of antennas to send a signal from the single reader/transmitter. An exchange of signals with each one of the plurality of transponders occurs during the activating sequence when the one antenna dedicated to that one transponder is activated.
