Abstract
Circuit for a data carrier, which circuit is capable of supplying identification information to a communications arrangement. A circuit () for a data carrier (), which is able to communicate contactlessly with a communications arrangement (), is provided with a memory stage () for storing identification information (II) consisting of information units and suppliable to the communications arrangement () and with a signal-processing stage () for processing an indicator signal (IS), which indicator signal (IS) indicates a substantially simultaneous appearance of two different information units, of which two different information units the one information unit is contained in the identification information ([I) stored in the memory stage () of the circuit () and the other information unit is contained in different identification information (II') stored in a memory stage of a different circuit (′), and which indicator signal (IS) is generated by the communications arrangement () upon detection of such a substantially simultaneous appearance of different information units and is communicated to the circuit (), wherein the signal-processing stage (), as a consequence of a processing of the indicator signal (IS), is arranged to interrupt the supply of the identification information (II) after the appearance of the information unit that has caused the indicator signal (IS) and to flag at least the information unit that has caused the indicator signal (IS).
