Royal Bank of Scotland apologises over card problem
The Royal Bank of Scotland (RBS) group has apologised after customers of Royal Bank of Scotland, NatWest and Ulster Bank were unable to use cash machines at other banks.
RBS said customers were affected from 10:40 BST-13:15 BST but the problem had now been resolved.
A spokeswoman apologised "for the inconvenience" and said customers could still use the banking group's machines.
She was unable to confirm which parts of the country were affected.
Customers were still able to use RBS, NatWest and Ulster Bank cash machines.
Affected customers took to Twitter to express their frustration.
Richard B, from Blackpool, tweeted: "Great Natwest down can not draw any money out from any cash machine. No branch nearby. Saturday ruined #natwest #badservice."
David C, from Glasgow, meanwhile, tweeted: "@RBS_Help why can't I use my card in any cash machine today? Is this us better together not letting me take my own money out. Please sort it."
And Paul O'Hara tweeted: "@UlsterBank_Help once again ulster bank won't give money from the ATM! I might have to move all of my accounts. Really angry."
