ABSTRACT:
A remote-readable identification tag (T) that is provided with at least two resonance circuits (81 . . . 8n) and at least one transmitter/receiver antenna system (1) coupled with the circuits. The at least two circuits have a respectively different resonant frequency. A delay device (6) of the remote-readable identification tag delays a signal response between a signal received by the antenna system and a signal emitted in response by the antenna system, e.g., by delaying feeding the received signal into the resonance circuits.
