Abstract
The invention relates to a method and system for reading a dynamic set of tags present in the electromagnetic field of a polling device, consisting in updating cyclically a list of tags present in the electromagnetic field and minimizing the time for checking the presence of tags already identified, by assigning to each of these tags a sequence number whose binary size is significantly smaller than that of the ID code and that allows to realize a “call” of the tags present by enumeration.
