I'm interested in technologies that involve the implantation of chips in vehicle plates. I know that Utsch, in Germany, is one manufacturer that offers a chip on a board. Could you tell me if there are any other such companies that do so, anywhere in the world?
The BIBA Institute, at the University of Bremen, working with J.H. Tönnjes E.A.S.T. GmbH & Co. (a developer and manufacturer of license plates) and Kathrein Sachsen GmbH (an RFID reader and antenna supplier), has developed and tested passive RFID license plates that outperform smart labels on windshields, as well as on-metal passive tags for vehicle identification (see RFID License Plates: A Successful In-Metal RFID Application). I do not know if they ever created and marketed the tagged license plate, however.
In addition, Tönnjes, in partnership with license plate manufacturer Kirpestein B.V. Automotive and RFID chipmaker NXP Semiconductors, conducted a trial last year that proved passive ultrahigh-frequency (UHF) RFID license plates can effectively identify moving vehicles even in the most challenging environments. The three firms put the technology to the test at a Netherlands military base, via a variety of heavy military vehicles moving at high speeds, to simulate some of the most difficult circumstances in which license plates might need to be read.
It's also worth noting that several countries are using RFID in vehicle-registration stickers (see Electronic Vehicle Registration Picks Up Speed).
