The Magellan Wireless Back-Up Camera kit comes complete with a license plate mountable camera, transmitter, wireless receiver, vehicle power adapter, installation hardware, and instructions.
And license-plate readers mounted on patrol cars scan traffic and parking lots, comparing a list of known stolen plate numbers to what the camera sees.
After the camera system captured each driver's license plate, the bill for the toll would be assessed electronically, with the assistance of motor-vehicle departments from around the country.
