    Abstract: Data carriers for inventorying by means of a communication station, whereby the communication station and each data carrier are brought into communicative connection, and each data carrier brought into communicative connection with the communication station is configured to generate a response signal that renders possible an inventorying of the data carrier and is capable of delivering a generated response signal with the use of a transmission start moment that can be selected from a plurality of transmission start moments, each data carrier tests whether another data carrier is already giving its response signal. Each data carrier is configured to discontinue the generation or delivery of its response signal if another data carrier is already providing its response signal.
