Abstract:
1. 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, comprising 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 greater than 1, (b) analyzing the code of each label by scrolling through this code block of m bits by block of m bits, (c) assigning a same serial number to all of the labels with a same partially identified code on a row being analyzed, a number of serial numbers assigned representing a number of groups of labels with the same partially identified code, (d) establishing a cross reference table between each serial number and a value of the partially identified code, and (e) updating the serial numbers of the label as the detection of the bits of the identification codes progresses.
