Abstract
This disclosure describes techniques for operating an inductive coupling reader. The techniques include operations comprising: applying an excitation frequency to a resonance circuit of the inductive coupling reader; detecting a change to a resonance frequency of the resonance circuit of the inductive coupling reader; and in response to detecting the change to the resonance frequency of the inductive coupling reader, adjusting the excitation frequency being applied to the resonance circuit.
