We have a barcode on the back of the card already. We don't need a new protocol to handle this.

The registration is from the state and attached to the car. They don't need the card.

Insurance is attached to the car and required for registration. So we shouldn't need to hand that over either.

The car is registered to a person and cops should be able to get information on a person that owns the car which is most of the time.

What I'm saying is that most of the time nothing is actually needed that they shouldn't be able to get from a license plate.

NJ is not an efficient state when it comes to bureaucracy (or they like potentially screwing people, which matches my experience with firearms ownership in this state).
