Beschreibung
Zusammenfassung:	The data carrier includes a card body (1) and an indicator layer (2b) essentially parallel to its main surface area, whose physical characteristics are already changed irreversible at such mechanical and/or thermic load of the data carrier, at which the physical characteristics of the card body are not yet changed irreversible. The indicator layer comprises preferably at least one indented breaking point (3a, 3b), and at least one brittle area.
