RTE News report some Visa transactions are not being processed due to a service disruption, the company has said.
The incident is affecting Visa services across Europe, including in Ireland.
The company statement added that they are investigating the cause of the disruption and are working as quickly as possible to resolve the situation.
Bank of Ireland has said it is aware of an issue with Visa Debit cards, and that account holders can make cash withdrawals at any Bank of Ireland ATM.
Permanent TSB also said that its Visa Debit cards can be used at the bank’s ATM.
However, it reported that people have only been able to successfully use them at point-of-sale outlets intermittently.
AIB said it is aware of intermittent issues with AIB cards and is working to resolve the matter.
Paymentsense, which provides card machines, online payment gateways and virtual terminals to some 60,000 independent businesses in Ireland and Britain, advised users to try paying via contactless transactions.
“We have been informed that Visa has corrected the outage and transactions are now starting to go through.
“There is still some intermittency however, we believe this is due to a backlog of transactions,” it said.
“We now understand that contactless transactions have a better chance of going through.
“We’d encourage affected customers to try contactless transactions where possible.”
