Visa says service returning to normal

A Sainsbury's store in Vauxhall, London, is not taking card payments

Visa says its service is "close to normal" again following a system failure which left customers across Europe unable to make some purchases.

The company apologised and said it had no reason to believe the hardware failure was down to "any unauthorised access or malicious event".

Its statement came five hours after it had initially acknowledged the problem.

Shoppers had reported being stuck in queues as Visa transactions were unable to be processed.
