Methods and systems read a computer readable code on a printed vehicular violation using an optical sensor of a portable computing device and access a vehicular violation database to identify a registered vehicle corresponding to data in the computer readable code. The methods and systems retrieve a vehicular violation history for the registered vehicle. The vehicular violation history is a history of vehicular violations maintained by the vehicular violation database related to the registered vehicle, and includes a payment status of fines associated with the vehicular violations. The methods and systems therefore display this vehicular violation history and display an option to pay one or more of the fines on the graphic user interface. The methods and systems then receive payment information into the graphic user interface, and process the payment of one or more of the fines through the portable computing device, using the payment information provided.
