U.S. Considers RFID-enabled License Plate Scheme
A controversial plan to embed radio frequency identification chips in license plates in the United Kingdom also may be coming to the United States, experts said. The so-called e-Plate is a license plate that also transmits a vehicle's unique identification via encryption that can be read by a small detector, whose output can be used locally or communicated to a distant host. A single RFID reader can identify dozens of vehicles fitted with e-plates moving at any speed at a distance of about 100 yards.
