ABSTRACT:
The invention concerns a method for reading a set of electronic labels, each comprising a distinct identification code of N bits and situated in the electromagnetic field of an interrogator device, characterized in that it comprises the following steps:a) for each given code of N bits, defining an elementary analysis block comprising m bits, where m is a sub-unit of N,b) analyzing the code of each label by scrolling through this code, block of m bits by block of m bits,c) and, for a given label, generating a serial number representing the number of labels identified before this label in such a way that the interrogator knows at any moment the number of labels present in the electromagnetic field,d) establishing a cross reference table between the serial numbers generated and the values of the identification codes of each label.
