License plate validation
First Claim
1. A radio frequency identification (RFID)-enabled license plate, comprising:
- a metal plate comprising a first cutout portion defining a first hole in the metal plate and a second cutout portion defining a second hole in the metal plate; and
a RFID assembly integrated with the metal plate and positioned across the first hole defined by the first cutout portion, the RFID assembly comprising a RFID chip and an antenna, wherein the RFID assembly further comprises;
a front cover attached to a first side of the metal plate and covering the first hole defined by the first cutout portion; and
a back cover attached to a second side of the metal plate opposite to the front cover and covering the first hole defined by the first cutout portion such that the first cutout portion is positioned between the front cover and the back cover;
wherein the RFID chip is sandwiched between the front cover and the back cover; and
further wherein dimensions, spacing and locations of the first cutout portion and the second cutout portion are configured such that a slot antenna is formed from the metal plate, the first cutout portion, the second cutout portion and the RFID assembly and the slot antenna resonates at multiple frequencies.

Abstract
A license plate validation system for a vehicle is disclosed. This license plate validation system includes: a radio frequency identification (RFID) reader located inside the vehicle and configured to read from an RFID-enabled license plate on the vehicle upon detecting an attempt to start the vehicle; and a microcontroller coupled to the RFID reader and configured to receive, from the RFID reader, information obtained from the RFID-enabled license plate and subsequently determine, based at least on the received information, whether the vehicle is properly registered. In some embodiments, the microcontroller and the RFID reader are integrated as a single electronic module.
