Asda was forced into a nationwide apology yesterday (Sunday 30 October) as a "technical issue" related to the grocer's payment system caused delays at the checkout across the UK.

Long queues formed as the retailer's card payment terminals in all stores were unable to process transactions, and some customers took to social media to post images of staff using old-fashioned, pre-chip and PIN card readers. Other stores were only accepting cash payments, disrupting many consumers throughout Sunday trading.

Some shoppers abandoned their trolleys and left stores to do their shopping elsewhere, others queued at ATMs so they could make cash payments. Others were more patient and waited to have their shopping processed as Asda worked with its technology partners to resolve the issue throughout the day.

A spokeswoman for Asda said on Sunday said it was "a technical issue with our card payment system in stores".

She added that payments were being processed as quickly as possible and apologised to customers "for the inconvenience this has caused".

Essential Retail understands that the glitch was fixed last night and Asda is now fully open for business, taking all forms of transaction.
