TACOMA, Wash. -

Computerized license-plates readers have revolutionized the way police look for stolen cars.

One Tacoma officer says the cameras on his patrol car can scan 2,500-to-5,000 cars a shift. The computer matches the plates against the list of plates from stolen cars.

The News Tribune reports the city plans to expand the use of license plate readers to parking enforcement.

Parking officers will be able to tell if a car has overstayed its time limit or if the registered owner has unpaid parking tickets.
