A number of car parks that Parking Awareness Services manage are monitored using automatic number plate recognition (ANPR) cameras. It is not a requirement to display a ticket within your vehicle unless the signage states otherwise. Our systems link your transaction from the payment machine to your vehicle registration. With this in mind, you should always ensure that you enter your full and correct vehicle registration into the payment machine when purchasing a ticket. If you do not receive a ticket from one of our parking machines, it may be that your transaction was not completed correctly and as a result, your payment may not have been successful. In all cases we would advise that you read the terms and conditions of parking carefully as these can vary from one car park to another.
