An outage with Visa's card payment network is causing chaos for businesses across Lincolnshire.
Credit card company Visa is experiencing a service disruption across Europe which is preventing transactions being processed.
The disruption is also affecting some online transactions, the company said.
On Friday, Visa said the system was "close to normal" five hours after publicly acknowledging the problem. "Due to a systems failure, we fell well short of this today". "We are doing our best to help our customers and apologise for any inconvenience".
Customers around Europe vented their frustrations on social media, with some unable to pay bills or order taxis overseas.More news: Ozil contract complicating Arsenal deal for Ramsey
Sandra Foy, who owns a bookshop in Manchester, northwest England, told Sky News television: "I run a small business and the loss of any business is a big deal for us".
The BBC posted a picture of a London supermarket worker standing outside holding a sign reading: "cash only". "We will keep you updated".
She was flustered trying to pay her bill and then add the extra value points to her loyalty card at the Customer Service desk.
While investigations into the causes of the failure are ongoing, Visa Card users are getting into trouble, and something obviously needs to be done as soon as possible.
A spokesman for the retailer said: "The issue is intermittent, so it's not all cards, it's not all stores and it's not all checkouts".
