Method of reading a plurality of non-contact data carriers, including an anti-collision scheme

摘要

A method of inventorying data carriers ( 2 ) by means of a communication station, whereby the communication station and each data carrier ( 2 ) are brought into communicative connection, and each data carrier ( 2 ) brought into communicative connection with the communication station is capable of generating a response signal (IDS) that renders possible an inventorying of the data carrier and is capable of delivering a generated response signal (IDS) with the use of a transmission start moment that can be selected from a plurality of transmission start moments (t 5 , t 6 ), each data carrier tests whether another data carrier ( 2 ) is already giving its response signal (IDS). Each data carrier ( 2 ) subsequently discontinues the generation or delivery of its response signal (IDS) if another data carrier ( 2 ) is already providing its response signal (IDS).
