Abstract

A passive transponder includes a receive antenna for receiving an input signal. A frequency generator and modulator receives the input signal and outputs a data carrier signal having a frequency independent of the input signal frequency. A programmable memory and thermistor are provided to produce user ID data and temperature data which is combined with the output signal.
