SHOPPERS in York will act as guinea pigs for a supermarket giant's new gadgets.

Asda's Monks Cross store is set to trial pioneering self service devices to help people pay for their groceries, before potentially rolling them out across the country.

The brand is using the city supermarket to gather feedback on a host of new technology, and will use the store to see what staff and customers think.

A spokesman for the company stressed no jobs are at risk under the changes.

Among the new equipment are hybrid tills that can flip between being a normal checkout and a self-service checkout, and some additional "scan and go" scanners that mean customers can swipe their purchases as they go through the store.

The company says staff will remain at checkouts to either help customers log their purchases or do it for them.

Asda claims the new kit will increase the number of options available to customers around how they pay for their shopping when they visit the store, but will not make Monks Cross 100 per cent self scan.

A spokesman for Asda said: "Our customers are changing the way they shop with us so we’re testing new ways to serve them as they checkout, alongside a new till layout in our Monks Cross store.

"We think this could help our customers get through checkouts quicker, while still enjoying the friendly service they love from our colleagues."

This is not the first time the Monks Cross store has been picked to lead Asda's revolution.

The supermarket tested a 3D printing service in October 2013 when shoppers were given the chance to trial a device which allows objects up to the size of a family car to be scanned and printed in a miniature form.

Scanner cameras captured every angle of the subject during a two-minute scanning session before building a solid object.
