| Zusammenfassung: | The transponder (2) has a metallic shield (4) with an interruption, while an antenna coil (6) is provided with a winding. The antenna coil is surrounded by the metallic shield, where a chip (8) is connected to the antenna coil. A switch (10) is arranged to bridge the interruption to the non-actuated state, so that a closed circuit is formed in the metallic shield and the transponder is not accessed from the outside. The metallic shield has a circular shape, and is provided as a metallic pipe with the ends opposite to the point of interruption without electrical contact. An independent claim is included for a method for manufacturing the transponder. |
