Cheshire East Council is advising customers using its car parks across the borough not to use the PayByPhone service at the present time.
A spokesperson from Cheshire East Council said "The council has been informed by the operator that some customers may experience issues with transactions while banks and payment services providers deal with some issues affecting their services.
"Until the current issue is resolved, customers are advised to use cash, credit, or debit card. It is hoped that the PayByPhone service will be fully restored as soon as possible.
"PayByPhone have informed the council that they have become aware of a 'significant number' of transactions being declined as app providers and merchant banks carry out improvements to their systems.
"The problem is not confined to PayByPhone but other digital vendors too."
