Abstract (en)
[origin: WO0191037A1] The invention concerns a method for detecting simultaneous transmissions of electronic tags through an interrogation/reading/recording device comprising steps which consist in: (a) transmitting at the beginning of each electronic tag message a particular sequence of signals (90, 92, 94, 96), which is selected from a set of particular sequences; (b) identifying, on receiving messages through the interrogation/reading/recording device, said sequence of signals received at the beginning of each message; and (c) detecting the simultaneous transmission of at least two electronic tags if the identified sequence of signals (98) does not correspond to one of the particular sequences of said set.
