While, in 2013/14, there were no overpayments as ticket machines were programmed to give the appropriate time for the money inserted.

In the last three financial years, the council has made more than £3,100,000 per year in car parking revenue in Exmouth, Sidmouth, Honiton, Axminster, Budleigh Salterton, Beer, Seaton, Colyton, Lympstone and Ottery St Mary. …

… council spokeswoman said introducing the parking permits had meant customers could not buy parking time in 10p increments because there was not enough memory available in the current machines, so they introduced 50p increments.

This was because the number of ticket prices, which would be a new price point for every six minutes, to allow 10p increments, would be too much to continue alongside the new permit options.

To compromise, they introduced 50p increments on the same tariff, meaning customers would need to purchase parking in 30-minute periods rather than the previous six-minute increments – the minimum payment of 50p did not change. …”
