Anti-collision

In RFID systems, anti-collision refers to a method by which several tags in the same reading field are uniquely detected one after the other without their responses overlapping. This is particularly important when many objects are to be read simultaneously, for example during bulk reading or at an RFID gate. The method controls communication so that individual identifiers can be read out reliably and completely. As a result, detection quality, process reliability and speed increase in automated workflows. Anti-collision is a fundamental function for stable RFID processes with many tagged objects in motion. The reliable detection of several containers, cartons or pallets at gates and conveyor lines depends directly on a coordinated reading method.
