Abstract
A method for tuning a radio transponder having an antenna, a transceiver unit and a resonant circuit connected to the antenna, wherein the resonant circuit includes a plurality of capacitors arranged in parallel, where each capacitor is arranged in series with a fuse, where a capacitor is switchable via a fuse arranged in series to tune the resonant circuit, and where a control unit associated with the resonant circuit is configured to produce a switching signal for a respective fuse of the resonant circuit based on a control signal transmitted by a radio transponder reader.
