<p>A process is disclosed for verifying the authenticity of a data carrier (1) having at least one integrated circuit (3) with storage units and logic units, as well as a data transmission line for exchanging data with an external device. The invention is characterised in that the integrated circuit has an additional, separate, hard-wired circuit (2) for transmitting and/or receiving data during the switching on sequence. The separate circuit (2) is used for verifying the authenticity of data. The first data transmission or reception is completed within a defined time range of the switching on sequence during which the data transmission line is not yet in a defined state.</p> |
