Walking down London’s Oxford Street, a new trend has begun to form - shoppers are no longer subject to lengthy checkout queues, but instead have to contend with a self-checkout kiosk.

Self-checkouts are now the norm as supermarkets and retailers from Tesco to Sainsbury’s to Amazon have even begun experimenting with more advanced just-walk-out technology.

Other sectors, such as fashion, general merchandise and homewares, are a few steps behind, however - and have just begun trialling such checkouts in stores.
