So what happens when cash has gone and digital systems go down? Sainsbury’s unable to take contactless payments with many tills cash only and cancels all Saturday deliveries

 Tesco and Sainsbury’s have both been hit by an IT meltdown just that has impacted home deliveries and stopped customers from using contactless payment at the tills on one of the busiest shopping days of the week.

Tesco has cancelled some home deliveries today due a ‘technical issue’, a spokesperson told MailOnline, in a situation echoing the online shopping chaos experienced by rival Sainsbury’s this morning.

The Every Little Helps grocer did not specify how widespread the issue is, but dozens of Tesco customers complained online that their orders had been cancelled or delayed this morning.

Sainsbury’s customers were left fuming after the supermarket suffered an ‘error with an overnight software update’ that impacted its online ordering system and in-store payment options.

Frustrated shoppers are being forced to wait in long queues and pay with cash while the company was ‘experiencing issues with contactless payments’. Customers also complained that the grocer’s ATMs ran out of money due to the influx in withdraws.
