Abstract (en)

[origin: WO0163216A1] The invention relates to a method for the checking of an object by means of a transponder and a transceiver, whereby permanent data is stored in the transponder connected to the object, which may be remotely read by the transceiver. Said transponder (2) is arranged as a logic circuit (20, 30), with one or several connectors (23), for the recording of temporally variable data, which is serially transmitted by a modulator (26) and, along with an identification of the object, also performs a functional check of the object and the individual components thereof.
