Sainsbury’s is also expanding its SmartShop mobile payment scheme to offer till-free shopping in more than 100 convenience stores across the UK by the end of this week.
Nigel Blunt, director of ecommerce at Sainsbury’s, said: “We’re always on the lookout for how we can make our customers’ lives easier using technology.
“We’re trialling a virtual queuing system which enables shoppers to hold their place in the queue using their smartphone and we will be listening closely to feedback from our customers and colleagues.
“We’re also rolling out SmartShop Mobile Pay to even more convenience stores, offering customers fast and contactless shopping that will help them get in and out of the store even quicker.”
