The bit below is an area that 3M say are concerned about, a break on removal tag would stop these people changing plates or RFID tags in one fell swoop, if 3M didn't use break on removal in the system they are talking about below then it could easily be foiled, I am talking about this bit,"such a system could cross check the electronic and visual number plates and alert the enforcement agencies if it detected any discrepancy between the two."

Perhaps more likely, he feels, is the addition of common platform technology that supplements existing systems – for example adding camera optimised technologies to the traditional number plate. Such a move would increase the accuracy and confidence level of automatic number plate recognition (ANPR) systems. But that approach also has its drawbacks as McGurran points out: “You don’t want to give people even more reasons to steal licence plates.” This is a theme that causes him concern.

Perhaps more likely is what he calls an ‘RFID enabled 3rd license plate’ which would be built into or attached to the vehicle and uses a dedicated protocol. In instances where there were also ANPR cameras, such a system could cross check the electronic and visual number plates and alert the enforcement agencies if it detected any discrepancy between the two.
