Abstract

A universal tag (1) for use with a variety of readers of different designs comprises transducer (3), a modulator (11) connected across the transducer (3), and a control means (13). The control means (13) causes the modulator (11) to drive the transducer (3) with a plurality of different message waveforms after interrogation by a reader, the tag identity being embedded in each of the message waveforms. The message waveforms can be transmitted either simultaneously, sequentially, or both ways. A message waveform is comprised of a sequence of contiguous waveform segments, each waveform segment representing the value of an N-bit group, N being an integer. A waveform segment is a periodic signal characterized by the parameters frequency, phase, and amplitude. The waveform segments which represent the values of an N-bit group are differentiated by the values of at least one parameter.
