DEVICE FOR READING AND MARKING A PRINTED CARD-SHAPED DATA CARRIER

摘要

The invention concerns a card-shaped data carrier comprising a card body which has an inner electronic module for contactless communication with a coding and/or reading device and an external heat-sensitive layer (32) for the visually readable display of data stored in the electronic module as a result of thermal impact. The heat-sensitive layer (32) is designed to be reversible such that marks can be inscribed in a first temperature range and existing marks can be deleted in a second temperature range. The heat-sensitive layer (32) is disposed on the card body (1) in at least one sub-area (8) thereof.
