The fixed unit is arranged to establish an electromagnetic connection with the personal element and a connection via a telephone line to an operations center. The fixed unit is equipped with a CPU associated with a fingerprint reader and a radio receiver arranged to interact with a similar radio transmitter fitted in the personal element together with a CPU that controls its operation. A sensor is provided to detect any interruption and/or anomalies in the connection between the fixed unit and the personal element and to send an alarm to the operations center.
