UK retailer Sainsbury’s is to increase the use of its mobile payment scheme to seven more stores.

The grocer began trialling its Mobile Scan & Go service in October last year. The scheme allows customers scan items as they shop using their iPhone or Android phone and pay at the till without unloading their trolley or bags.

The payment scheme, which was initially trialled in three stores – Bethnal Green, Clerkenwell and Tadley, Hampshire – will now be extended to ten stores across the UK.

“Early feedback indicates that customers love the fact they can keep a running total and the savings they enjoy during their shop – making it easier to stick to a budget,” a spokesperson for Sainsbury’s told just-food.

The scheme has just been rolled out to an additional store in Colney, Norwich and the spokesperson said there are plans to add up to six more stores going forward.

Of the scope the scheme offers, he added: “In future, it is possible that the app could act as a mobile wallet, where customers pay for their shopping on their smartphone and avoid queuing at the checkout completely.”

He said the scheme may also be adapted to be able to “point customers directly to items in store”, remind them if they’ve forgotten a regular item, and suggest deals and new products based on their shopping and Nectar card history.
