A next generation ticket machine has appeared at the Civic Car Park in Abingdon. As well as the new £1 coin it will also be able to take contactless payments, and Chip and Pin cards. So motorists staying more than the two hours free parking have lots of options including paying for their parking via the Connect Cashlesss mobile phone app.
The new machine even opened the coin slot when I made a movement nearby. I have not heard it speak yet but would not be surprised if it has that capability.
