These walk-up parking machines allow parking payment for Pay & Display, Pay By License, or Pay By Space. There are no barrier gates to control access to the lot. Parkers enter, park, then pay. For Pay & Display mode, a receipt may be required to be placed on the dashboard of the vehicle so that that Parking Enforcement Officers may easily enforce parking violations.
For Pay By Space mode, the Parker enters the space number where they parked, then pays for parking. Parking Enforcement Officers may print Valid Space or Empty Space reports to monitor parking violations. Also, such reports may be viewed on-line or on parking citation writers. Similarly with the Pay By License mode, the Parker enters their license plate, then pays for parking. Parking Enforcement Officers may view valid license reports from the parking machine, on-line or on their parking citation writer.
