The invention concerns a method for identifying electronic labels affixed on products using a querying device, characterised 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 (rectangle 62); b) counting, during the first cycle of Ns windows, the messages received from the electronic labels to determine the number ni of identifications, the number nv of windows or blank spaces and the number nc of collisions (rectangle 64); c) stopping the process if nc = 0 (rectangle 68); or proceeding to step d) if nc ≠ 0; d) calculating a number Ns1 of emitting windows for the next cycle on the basis of the values of Ns, ni, nv and nc (rectangle 70); going back to step a) with Ns = computed Ns1 (rectangle 62).
