Abstract
An automated toll collection system based on visual recognition of a license plate with a supplemental enhancement to confirm the character recognition of the license plate is disclosed. In an embodiment, a supplemental graphic insignia encodes a check-sum for the license plate characters. The insignia is recorded at the same time as the license plate and the check sum is decoded to confirm the interpretation of the characters on the license plate. Other forms of confirmation devices are also disclosed, including RFID devices.
