Summary:A method for operating a communication system comprises a transponder having at least one antenna, in particular in the form of a portable data carrier, and a reading device having at least one antenna. The reading device is configured to exchange data with the transponder. An exchange of data between the transponder and the reading device is possible within a predetermined range. A measurement and evaluation is effected of the time of a command transmitted from the reading device to the transponder and the receipt of a corresponding response of the transponder by the reading device. In so doing, a processing is effected of a card-individual length of time T_icc, wherein the card-individual length of time T_icc specifies how long the transponder takes for the receipt and the processing of a command received from the reading device and the sending of a corresponding response.
