Sainsbury's has confirmed that it experienced payment issues impacting online grocery orders on Wednesday.

Following reports that a number of shoppers had card payments fail when trying to pay for online orders, a spokesperson from the retailer initially told Sky News that the technical issue was linked to problems at Visa.

However, the company later said that Barclays was to blame for the disruption.

The news website said that on Wednesday Sainsbury's was working with Visa and Barclays to tackle the problem.

Sainsbury's also confirmed that the issue has not been linked to a cyber-attack, with the company's website and app working as usual.

"We're working with one of our payment providers to resolve a temporary issue processing some payments for our Groceries Online service," a Sainsbury's spokesperson told Sky News. "We continue to deliver orders for customers and our website and app are working as normal."

Visa said that its systems were operating normally and that it was working with its partners to investigate.

A Barclays spokesperson said: “Due to a limited technical issue, some customers had payments for online orders where retail deliveries were due yesterday declined. This was specific to online orders where payments were due upon delivery and was quickly resolved. We are very sorry for any inconvenience this caused.”
