A number of Bank of Ireland customers experienced "technical difficulties" while attempting to use their Visa debit cards for point-of-sale transactions for a period today.
In a number of cases card transactions were declined, despite customer accounts having sufficient available funds.
Some customers of the lender had also reported issues while attempting to withdraw funds from ATMs.
The problems first arose earlier this afternoon, however, by 4.30pm the bank said the issues had been resolved.
Visa debit cards are now working normally. We'd like to sincerely apologise for inconvenience some customers experienced this afternoon.— Bank of Ireland (@talktoBOI) June 27, 2016
