An alteration in the function, parameter, property or characteristic is detachable. The wire (1) is coupled to the electronic unit (5) in such a way that at least a function, parameter, property or characteristic is altered if the wire (1) is clipped off. The electronic unit is a transponder unit (5), where the wire comprises at least a part of an aerial (12) for the transponder unit. The transponder unit comprises two identical differently programmed, programmable transponders. The wire forms part of an aerial (12) for one of the transponders in the unit, so that the transponder which is coupled to the wire does not respond to a radio frequency pulse if the wire is clipped off. |
