Method for operating an authenticity tag

Abstract

An authenticity tag includes a carrier for attachment to an object, a plurality of electrically conductive areas and a controller attached to the carrier. The controller includes a detector for detecting an electrically detectable quantity at the electrically conductive area, a memory for storing a comparative quantity and a communicator for communicating at least one of the comparative quantity, the electrically detectable quantity detected and a result of a comparison of the electrically detectable quantity detected and the comparative quantity to the outside.
