Abstract
A data carrier (1) for contactless communication with the communication station comprises firstly a receiving stage (3) for receiving a request signal (IS), secondly a storage facility (16) for storing at least two items of status information (EASB1, EASB2), thirdly a readout facility (15) for reading out one item of status information (EASB1, EASB2) at a time in response to receiving the request signal (IS), fourthly a processing circuit (18) for processing the status information (EASB1, EASB2) read out in each case so as to create a transmission signal (MCRS) suitable for transmission to the communication station, fifthly a recognition facility (22) for recognizing the status information (EASB1, EASB2) read out in each case, and sixthly a control connection (25) between the recognition facility (22) and the processing circuit (18), such that the processing circuit (18) can be influenced via the control connection (25) into altering a transmission parameter for a transmission signal generated by the processing circuit (18) as a function of the status information (EASB1, EASB2) recognized and readout in each case.
