Abstract: A vehicle tracking and auditing system for construction projects creates electronically stored records used in the invoicing and auditing procedures of a construction project. A unique preprogrammed identification code contained within a touch button memory chip is affixed to a vehicle. A dual function scanner is used to create a record of the vehicle arriving or leaving a designated area by reading an encrypted bar coded load ticket and then reading the touch button affixed to the vehicle. The scanner stamps a time and date associated with each record. The records are electronically stored in the scanner until the records are downloaded to a host computer through a base station. Computer software queries the records into desired reports and invoices. Exemplary reports detail when a vehicle arrived or left a designated area, summarize the total volume of construction material carried by company or by a specific vehicle, route time of the vehicle, and identify potential fraud.
