Abstract
The invention concerns a method for identifying electronic labels affixed on products using a querying device, characterized in that it comprises the following steps which consist in: (a) indicating to the electronic labels the number Ns of consecutive emitting windows of a first cycle or round; (b) counting, during the first cycle of Ns windows, the messages received from the electronic labels to determine the number n of identifications, the number n of windows or blank spaces and the number n of collisions; (c) stopping the process if n =0; or proceeding to step (d) if n ≠0; (d) calculating a number Ns1 of emitting windows for the next cycle on the basis of the values of Ns, n , n and n ; going back to step (a) with Ns=computed Ns1.
