Abstract: The present invention is a system installed in patrol vehicles such as highway patrol, or local police patrol. The system uses wireless technologies to scan and compare VIN (vehicle identification numbers) with license plate against the Department of Motor Vehicles database, and against the local police database for outstanding warrants. All passing cars would be processed. The system then displays the information on the patrol car's computer system, and notifies the police officer of any outstanding warrants, if the car is stolen, and if there is a problem with the registration or tags on the vehicle.
