Abstract

A data carrier (2) includes memory (16) adapted to store the information data (ID), and further includes first detection unit (28) adapted to detect first command data (CD1), and further includes initialization unit adapted to initialize, after detection of the first command data (CD1), the memory (16) for the storage of information data (ID), and further includes a second detection unit (29) adapted to detect second command data (CD2), and further includes write unit (32) adapted to write the information (ID) into the initialized memory (16) after detection of the second command data (CD2).
