Abstract: An RFID label comprises a resonant circuit consisting of a coil and a capacitor. The RFID label is provided with an additional element (13, 17, 20, 21) for regulating the resonance frequency of the resonant circuit. The additional element is applied to the surface of the RFID label after production of the same. The additional element can be especially a sticker with a conductive layer, which is stuck in such a way that it partially overlaps individual conductive surfaces of the label to produce an additional capacitance, or which is simply stuck into the coil to reduce the effective inductance of the coil. Alternatively, the element can be formed by a layer with a high relative permittivity which is applied between two conductive surfaces.

Abstract: Method and system for reading out and writing to RFID-transponders with inductive coupling including a read/write unit with a transmission frequency fs1 defined as a basic transmission frequency and a plurality of transponders operated at a resonance frequency fR. The resonance frequency fR is fixedly predetermined, then for operating conditions with a high distance range, the resonance frequency fR equal to the basic transmission frequency fs1 is selected. For operating conditions with a high recognition rate with a plurality of transponders located within a detection field, the basic transmission frequency fs1 is reduced to a fixed alternative value fs2 . This procedure guarantees reliable communication between the transponders and the read/write unit.
