The old 'pay and display' machines will be disappearing for ever from Windsor's River Street car park over the weekend.

It will end the need for drivers to guess how long they are going to stay, because they will no longer have to buy their ticket when they arrive.

The 'pay and displays' will be replaced by a 'pay on foot' system that will see drivers take a chip coin on entry, only paying when they leave according to the length of their stay.

Cllr Carwyn Cox, the Royal Borough's cabinet member for environmental services which includes parking, said: “I am pleased that we are able to introduce this system, which will allow visitors and residents to pay for the time that they spend in the car park and no longer have to worry about their ticket expiring.

“I am also glad that there are a variety of payment methods, whether it be cash, card or by using the Parkmobile application, and that we have also retained the ability for residents to benefit from the Advantage Card system."

If paying by cash or card, the coin can be inserted into any of the new payment machines, which will display the amount due. Once a payment has been made the chip coin will be returned and this can then be used at the exit barriers to leave the car park.

Blue badge holders or those choosing to pay for their parking through the Parkmobile application can go to payment machines and press the assistance button to get their chip coins validated. They can then exit by using the validated chip coin.

Holders of a yellow Advantage Card can still benefit from the same discounts by entering the last four digits of their Advantage Card when instructed by the machines.

Additional signage and instructions will be placed in the car park and staff will be on hand for the first week to assist users.
