Are there any examples of the technology being applied to this area?
In South Africa, RFID tags were affixed to millions of metal license plates in order to automatically identify vehicles and verify that they were properly registered. As far as I am aware, this is the only example of tags being affixed to license plates. It is far more common to affix tamper-evident RFID labels to windshields for the purpose of electronic vehicle identification. In Bermuda, for example, the island nation's cars and trucks have RFID-enabled registration stickers attached to their windshields. Other countries—including Brazil, China, Dubai, India and Mexico—have also implemented or plan to implement vehicle identification and registration systems. Fixed RFID interrogators installed at main traffic intersections or alongside roads, as well as handheld readers for use during traffic stops, can read the tags' unique ID numbers and then compare them with information stored in a back-end database to determine, for instance, who owns a particular vehicle, whether it is insured and if registration is up-to-date and taxes and fees are paid up. T reads collected over a period of time can help municipalities better understand traffic patterns and flow (see Electronic Vehicle Registration Picks Up Speed).
