Abstract
A data carrier (1) for contactless communication with a communication station (2) has an integrated circuit (7) and has a direct voltage generation circuit (20), and has detection means (28) for detecting a temperature prevailing in the data carrier (1) and in the integrated circuit (7), with the aid of which detection means (28) a representation signal (RS) representative of the prevailing temperature can be generated, which representation signal causes an initiation of a change of the temperature in the data carrier (1) and in the integrated circuit (7).
