Abstract
The disclosure describes a communication device and a transponder adapted to provide contactless communication with the communication device include time-value determiner with the aid of which at least one time value can be determined, which time value is representative of at least a part of the communication time interval which starts at a starting instant and ends at an ending instant, in which communication time interval communication between the communication device and the transponder is possible.
