The inventive device also comprises means for acquiring identification data (1) and management means (2). The aforementioned management means comprise means for storing authorised identification data (3) and processing means (4) which generate an identification signal when a successful comparison is made between an acquired identification datum and a stored identification datum. The management means are connected to control means (6) which produce an output signal (S0, , Sm) on the control line. The invention is characterised in that an input line is connected to the input and an input signal (E0, , En) travels over said line. The invention is further characterised in that the above-mentioned control means control the state of the output signal according to: (i) the input signal, and (ii) the identification signal. |
