Data carrier, has connecting unit provided such that physical characteristics of unit are modified by influencing external radiation to form safety characteristics and/or to modify electric conductivity and/or mechanical adhesion of unit

摘要

The carrier has an antenna device with a substrate and an antenna arranged on the substrate, where the antenna has an antenna terminal (9). An electrically conductive connecting unit (17) contacts the antenna terminal to a chip terminal (11) of a chip. The connecting unit is provided in such a manner that physical characteristics of the connecting unit are modified by influencing external radiation above a threshold temperature for forming safety characteristics and/or for modifying electric conductivity and/or mechanical adhesion of the connecting unit. An independent claim is also included for a method for contacting an antenna device with a chip device in a data carrier.
