Method and identification device remotely

This identification method between an inquiring system (1) such as a gate and labels (E) placed on objects to be identified and designed for passing through the inquiring field (2) consists in sending control signals from the inquiring system (1) to the labels (E) for the latter to transmit their codes. The known inquiring mode, in which the codes are supplied bit after bit and the labels simultaneously responding are successively inhibited so that only one should be active and identified at a time, is preceded by an identification test during which all the labels transmit their code at the same time in one go, which enables an immediate identification if only one label is present. When a label has been identified, the inquiring system (1) isolates it to exchange particular data with it.
