Two major banking groups have apologised to customers after technical hitches left people frozen out of their accounts.
Customers who bank with Halifax and Lloyds TSB, which are part of the same group, had their cards rejected in shops and were left unable to use some ATMS and online services. The Co-operative Bank also said it had experienced problems to its banking system, including people struggling to access online services.
Both groups said they have cleared up the underlying problems and neither could say exactly how many customers were affected.
Shopper Marc Dewhurst said he was visiting the Meadowhall centre in Sheffield when he tried to pay using his Halifax card but it was declined, despite him having the cash in his account.
He said: "Luckily I had just taken £50 out of a cash machine 15 minutes earlier. I went round to the Halifax and saw people shouting at the staff."
A Lloyds spokesman said: "Lloyds Banking Group experienced technical issues that affected some customers. All of our systems are now up and running. We are working hard to process the transactions impacted by this problem and they will be resolved before the close of play (on Friday).
"We know our customers rely on us, and we apologise for the inconvenience we have caused them."
A Co-op spokeswoman also apologised for its problems, which she said had lasted for a couple of hours.
She said: "We can confirm that our systems are now fully operational and customers should now be able to use their accounts as normal. We would like to apologise for the inconvenience caused by this temporary issue."
The latest incidents follow a recent string of banking glitches, including a huge IT meltdown over the summer which meant the accounts of NatWest, Ulster Bank and Royal Bank of Scotland customers did not update properly, causing chaos for many people for weeks.
