for recording an individual code assigned to the tag (2), and emitting means
(12) for emitting a signal representing the individual code; a portable
detecting device (4) has enabling means (16) for enabling the emitting
means (12) and for transmitting an inquiry signal to the tag (2)
and receiving, in response, the signal representing the individual code and emitted
by the emitting means (12) of the tag (2); and the individual code
