Abstract
During the implementation of an anticollision method by a reader station () to identify all data carriers () in the communication field (HF), in order to shorten the time slots (S) in which none of the data carriers () is responding or in which a collision of multiple responses from the data carriers () occurs, a time-slot progressing information (ZWI) is sent by the reader station (). The time-slot progressing information (ZWI) contains a time-slot number (ZN), which identifies the time slot (Si) next in line after the current time slot (S).
