These are procedures to handle the reading of multiple tags simultaneously because they prevent the problem of overlapping radio waves, emitted by different tags, that end up disturbing each other. Within a single electromagnetic field generated by a single antenna of a reader, it is possible to manage the reading of different tags thanks to algorithms called precisely anti-collision, which regulate the time intervals in which they are to be read. This way there is no interference and no risk of receiving incorrect or inaccurate information.
