Abstract

Labels (E) are identified by an interrogating system (5) in the order of their arrival in an interrogation field (3), which initializes and starts up a time counter (15) operated so as to prioritize the oldest label during identification. This prevents labels (E) passing through the interrogation field (3) without being able to transmit their identification code.
