Abstract

An arrangement for identifying a movable object includes a transponder disposed on the movable object and including an electrical memory that can be read out in a wireless manner by an electrical interrogating device which is disposes in proximity of the object. A sensor arrangement is disposed on the object and electrically linked to the transponder for writing a read-out-capable status information into the memory in response to irregular or unauthorized use of the object.

Claims

1. An arrangement for identifying a movable object, comprising:

a movable object;

a transponder disposed on the movable object and including an electrical memory that can be read out in a wireless manner by an electrical reading device which is disposed in proximity of the object, the transponder using a wireless supply of energy obtained from radio-frequency energy transmitted by the electrical interrogation device for activating the transponder and reading out the electrical memory; and

a signal transmitter disposed on the object and electrically linked to the transponder for writing a read-out-capable identification into the memory in response to irregular or unauthorized use of the object.

2. The arrangement according to claim 1, wherein the transponder is disposed in a hidden location on or in the object.

3. The arrangement to according to claim 1, wherein the memory includes a memory component containing an object-specific fixed identification which can be additionally read out.

4. The arrangement according to claim 1, wherein the object comprises a vehicle and the sensor arrangement comprises an electronic anti-use device connected to the transponder by at least one of a wireless connection and a wire.
