摘要:
A method for fitting a transponder with a chip and a coil to a metal body is disclosed. The coil is wound in the form of a bar and is electrically connected at its ends to the electrical connections of the chip, forming a transponder. The transponder formed is introduced in its entirety into a cavity in the metal body in such a manner that the coil axis (X) lies parallel to the metal surface. At least part of the coil is positioned in the region of a window in the metal body.

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.
摘要:
The invention concerns a transponder arrangement in which the transponder is disposed on a conductive surface. According to the invention, the coils forming the transponder antenna are aligned at a slight distance from the metal surface with their main magnetic field direction parallel to this surface.
