Abstract
Abstract A electronic license plate system having an identification device embedded in a license plate portion and electronics stored in a license plate holder ensures that the proper identification device is connected to the electronics. The identification device is constructed in a manner such that tampering with the device will render is inoperable. Also, if an improper license plate is mounted to the license plate holder of a vehicle, a security system will disable the electronics of the system or will transmit a alarm signal.
