Sainsbury's will be launching the UK's first supermarket with no tills - but will this catch on?

The experiment will put SmartShop Scan, Pay & Go technology to the test in a bespoke food-to-go store, making grocery shopping quicker and more convenient.

Despite the first till-free store being in central London, the idea could soon catch on as all you need is an phone with a camera and access to the internet.

Customers will scan and pay for products using the company's app and once finished they will need to scan a QR code to complete the process.

They will then receive an online receipt by email and be on their way.

This frees up store colleagues to spend their time on the shop floor, helping customers and keeping shelves fully stocked.

The stores will have a helpdesk to support anyone who wishes to pay with cash or cards. Currently, 82% of transactions in this London convenience store are cashless.

Sainsbury’s Group Chief Digital Officer, Clodagh Moriarty, said “We know our customers value their time and many want to shop as quickly as possible - technology is key to that.

"This is an experiment rather than a new format for us - it hasn’t been done in the UK before and we’re really excited to understand how our customers respond to the app experience.

"We’ll be with our customers and colleagues all the way over the coming months, iterating continuously based on their feedback before we decide if, how and where we make this experience more widely available.”
