PORTABLE DATA CARRIER, IN PARTICULAR A CHIP CARD

摘要

The invention relates to a portable data carrier, in particular a chip card. The portable data carrier according to the invention comprises one or more sensors (3, 4), which are each designed to detect an exposure of a surface of the portable data carrier (1) as a detection event by sensing measured values. Furthermore, the portable data carrier according to the invention comprises one or more output means (5, 6) for outputting signals that can be perceived by a user. The portable data carrier (1) according to the invention is characterized in that the portable data carrier according to the invention is designed to output a signal by means of the one or more output means (5, 6) if a detection criterion is fulfilled, wherein the detection criterion is fulfilled if the detection event is detected by at least a subset of the sensors (3).
