ABSTRACT:
A contactless data storage medium having a principal circuit component and a coupling element, with a controllable load provided for performing offloading modulation. A drawn-current controller is able to reduce the current drawn by the principal circuit component and simultaneously increase the size of the current through the load in order to provide an offloading potential for performing the offloading modulation.
