Abstract
A reader for reading a memory tag comprises a resonant circuit part, a frequency source, a tuning detector and a tuning controller. The resonant circuit part has a resonant frequency. The frequency source is operable to generate a driving signal and is connected to the resonant circuit part to provide inductive coupling to a tag. The tuning detector is responsive to the relative resonant frequencies of the resonant circuit part and a memory tag resonant circuit part of the memory tag to generate a tuning signal. The tuning controller is responsive to the tuning signal to control the resonant frequency of the resonant circuit part.
