A method of operating a carwash includes driving a vehicle to a point of sale station of the carwash, purchasing a carwash transaction, and taking a first picture of a license plate number of the vehicle after the completion of the purchase of the carwash transaction at the point of sale station. The license plate number is associated with the carwash transaction as a carwash ticket. The vehicle is then sent to a carwash queue disposed downstream of the point of sale station. The carwash ticket information is sent to a carwash tunnel. A second picture of the license plate number of the vehicle is taken right as it approaches the carwash tunnel. The license plate number is associated with the carwash ticket and the vehicle is washed according to a wash dictated by the carwash ticket.
