Method for collision-free data exchange between reading/writing device and mobile data carrier, reading/writing device and identification system

The invention relates to a method for collision-free data transmission between at least two read / write devices (SLG) and at least one mobile data memory (MDS), especially in an identification system with at least one attached to objects mobile data memory (MDS) for detecting object-related status and / or process data z. B. at a dispatch, transport and / or production system of the individual objects, wherein the data transmission via a transmission channel with at least one time slot (SID2) with at least two register areas (RB1) and (RB2) is done and the register ranges (RB1) and (RB2) according to a random identification numbers (1) and (2) of the mobile data memory (MDS) requesting read / write devices (SLG) are assigned. Furthermore, the invention relates to a read / write device (SLG), a mobile data memory (MDS) and an identification system for the application of such a method for collision-free data transmission.
