ABSTRACT:
The invention concerns a control and/or monitoring device comprising pairs (P, P′) of interactive members (1, 2; 1′, 2′) each of which includes an electronic label (1, 1′) identified by a specific identification code (KID1, KID1′) communicating with said label (1, 1′). For each pair (P) of interactive members, the inventive device also comprises a state encoder at least partially borne by the label (1), said encoder producing a state signal which is accessible to the reader (2) and representing a logic or analog state affecting the label (1) or a relationship between the label (1) and the reader (2).
