Long queues, barcode scanning and unexpected items in the bagging area - these are some of the frustrations we normally face when paying for shopping at a self-service checkout. All that could be set to change following the introduction of a new instant checkout scanner made by IBM.

Vishva Samani visits a petrol station in London that's piloting it. First broadcast on You & Yours, 15 February 2018.
