The identification of motor vehicles is often time-consuming and imperfectly performed. The universal product code (UPC) can be used to identify vehicles, and a laser detector used to detect the code can be linked with a computer database. No human intervention is required, and vehicles can be identified in a stream of traffic without slowing the traffic flow. Speeding can be detected, as well as stolen vehicles. Toll collection may be performed electronically. The UPC can be imprinted on a registration sticker, or can be placed elsewhere on the automobile, such as laminated onto automobile windows. Fig. 1 shows the UPC on the license plate 10 of a vehicle, which passes over a laser scanner 12 located in the roadway.
