Method and system for the secure detection of an RFID electronic tag
First Claim
1. Secure detection method implemented in a secure detection system intended to detect the presence of an RFID electronic tag, said system comprising a read/write station, said read/write station comprising an RFID communication interface intended to exchange data with the RFID electronic tag, first processing means connected to the RFID communication interface and second processing means connected to the RFID communication interface, said method comprisinga step of storage, by the first processing means and by the second processing means, of a unique identifier of the RFID electronic tag and of control data associated with this unique identifier,a writing step controlled by the first processing means for writing the control data in the RFID electronic tag,a reading step implemented in parallel by the first processing means and by the second processing means for reading the control data sent by the RFID electronic tag when the RFID electronic tag is located within the field of the read/write station,a checking step implemented by the first processing means and the second processing means for performing a check on the control data read against the control data stored during the storage step,a step of generation, by the first processing means and by the second processing means, of two output signals taking into account the check performed during the checking step.

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.
