Abstract:
1. A data carrier for the communication of communication data with a base station, comprising: processing means for the processing of communicated communication data, and voltage supply means which are arranged to receive on external supply voltage applied to the data carrier during a charging time interval until a turn-on instant and which are adapted to supply an internal supply voltage to the processing means, decoupled from the external supply voltage, during a consumption time interval starting at the turn-on instant, the processing means being adapted to interrupt the processing from an interruption instant, when the internal supply voltage decreases below a threshold voltage, until the turn-on instant, characterized in that there are provided time measurement means which are adapted to measure a processing time interval defined as the time interval from the turn-on instant until the interruption instant, and the voltage supply means are adapted to adapt the consumption time interval to the measured processing time interval.
