Abstract: The invention relates to a method and a system for the secure detection of an RFID electronic tag (ET1). This detection system comprises a read/write station (1), said station (1) comprising first processing means (12) and second processing means (13), the first processing means (12) and the second processing means (13) making it possible to read in parallel control data (CD) previously written in the RFID electronic tag (ET1) when the RFID electronic tag (ET1) is located within range of the station. The station controls the state of the machine according to the processing performed.
