Some customers had reported problems with ATM and point of sale transactions
Bank of Ireland says its Visa debit cards are now working normally, after issues earlier today.
Customers - including a number of people trying to take out money at ATMs abroad - took to social media throughout the afternoon to report problems with their debit cards.
According to Bank of Ireland, there were "intermittent" problems with ATM and point of sale transactions.
Credit cards did not appear to be affected by the issue.
In an earlier statement, Bank of Ireland said: "We are investigating this and will continue to update customers."
They added that the cards were working at both Bank of Ireland and Ulster Bank ATMs.
However, the bank took to Twitter this evening to confirm the problem had been resolved.
They apologised for any inconvenience caused by the issue.
We’re confirming all of our Visa debit cards are working normally for all point of sale chip & pin transactions and for withdrawals at all ATMs. We’re sorry for any inconvenience this may have caused.— Bank of Ireland (@bankofireland) June 21, 2018
