Customers have reportedly being left unable to make chip and pin payments across the UK and Ireland
Card payments network Visa is currently experiencing a widespread outage with millions of customers unable to use their cards across the UK and Europe.
This is the network that processes transactions for a number of banks as well thousands of small and large businesses.
The scale of the issue is currently unclear with Visa currently "investigating" the problem which started at around 4pm on Friday.
A statement from Visa told The Mirror: "Visa is currently experiencing a service disruption.
"This incident is preventing some Visa transactions in Europe from being processed.
"We are investigating the cause and working as quickly as possible to resolve the situation."
Mastercard payments are not affected and all payments are operating normally.
“We are seeing nothing abnormal on our network right now,” a spokesman said.
Disappointed shoppers have been unable to purchase items using chip and pin machines with many reporting failed transactions at major supermarkets including Asda, Sainsbury's and Aldi, who pay Visa to manage their card payments.
Mirror Money contacted all three retailers for a comment.
Asda told us it is experiencing difficulties in 'some' stores intermittently.
Another customer on twitter told us "it's chaos" in Asda's Bolton branch.
A Sainsbury’s spokesperson told The Mirror: "We are aware that Visa are currently experiencing problems. We are doing our best to help our customers and apologise for any inconvenience."
Card payments solutions company Paymentsense said "all merchants nationwide" are affected and unable to process transactions.
