For a transponder arrangement having a transponder arranged on an object, in order to achieve longer ranges than would be possible with a purely field-supplied response mode, the transponder is provided with a chargeable electrical energy store. An inductive supply of energy from a pump circuit situated on the object is used to hold the energy store in a charged state. The transponder arrangement can advantageously be interrogated not only in the active mode now made possible, but also in a passive mode which is known per se and is supplied with power purely by the interrogation field.

Transponder arrangement

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.

Arrangement for identification of a movable object having a transponder

A transponder as well as a data communications system equipped with such a transponder are described, with which identification and/or individual addressing of the simultaneously present transponders is guaranteed in a simple manner even in the case of the simultaneous presence of a plurality of transponders in the field range of the reader.
