Identification data carrier for identification system, has set of resonant circuit structures for electromagnetic resonant circuit, where structures have different resonant frequencies, capacitor and inductor
The carrier has a substrate and a set of resonant circuit structures for electromagnetic resonant circuits (200), with a capacitor (201) and an inductor (202) formed in the substrate. The substrate is a plastic carrier. The structures have different resonant frequencies. Each structure is selectively provided in an activated state and/or in a deactivated state which can be determined by the degree of absorption of an interrogating RF signal. Independent claims are also included for the following: (A) a read device for selecting information contained in an identification data carrier (B) an identification system comprising an identification data carrier (C) a method for manufacturing an identification data carrier.
