Identification medium with passive electronic data carrier storing a

The contactless identification carrier which can be carried by a person and having access functions for particular areas, particularly skiing areas, is constructed as a separate, flat carrier element and is fixed in interchangeable, portable manner on a personal bracelet PA. The carrier element (1) contains a passive, integrated, electronic data carrier MI with processor, as well as an integrated antenna (2) surrounded by a dielectric (4) and a detachable fixing device (3). The antenna has partly open radiating surfaces FAO, which are not covered by electrically conductive parts of the personal bracelet PA. This gives a universally usable identification and access medium with very good comfort and convincing practical characteristics.
