Abstract:
A method of conveying information to an interrogator includes the interrogator sensing the presence of a resonant radio frequency circuit that is tuned to a first resonant frequency. Responsive to a parasitic radio frequency circuit being brought to within a parasitic coupling distance of the resonant radio frequency circuit, the interrogator senses a shift in the resonant frequency of the resonant radio frequency circuit, wherein the shift in the resonant frequency conveys information to the interrogator
