Tesco is trialling a new system that it hopes will speed up the in-store checkout process.

Working with technology company NCR, the UK's largest retailer has introduced a checkout that uses imaging technology to automatically scan products placed on a conveyor belt. The idea behind the system is to reduce queues and allow customers to pay for their items more quickly.

The grocer has initially installed four units at its new Tesco Extra 24-hour store in Lincoln, marking the first public use of the solution.

Staff who would usually sit at a till-point and scan each item can now help customers unload their trolley onto the conveyor, while the system can process up to three customers in parallel using a new rotating turntable and re-designed collection area for scanned items.

Using imaging technology from Datalogic which automatically finds the barcode on any side of the product, NCR says the checkout is capable of scanning up to 60 items per minute.

Nigel Fletcher, productivity director at Tesco UK, said: "We are always looking for innovative ways to support our colleagues to give great service and to improve the shopping experience for our customers. We're looking forward to seeing what our customers in Lincoln think of the new checkouts over the coming weeks and months."

The introduction of new checkout points is just one of a number of technological moves Tesco has made over the last fortnight.

Earlier this month the supermarket announced it will be launching its own smartphone as it tries to take a share of the growing mobile market in the UK, while this Monday saw the retailer roll out contactless payment to all of its 6,000 payment points in London.

A Shop&Go trial also began this week at Tesco's Bethnal Green store in London, which allows customers to shop in the store as normal, spend at least £35, and then see their shopping delivered for free on the same day.

Ronen Levkovich, EMEA vice president at NCR Retail, commented: "As consumers increasingly expect a better experience, incorporating innovative software and hardware becomes increasingly important."
