Sainsburys are currently developing a new smartphone app which will allow customers to create shopping lists a t home, guide shopers to their chosen products, scan the items and pay for them without the need to visit a checkout. A trial of the technology is expected in the next couple of months. Shoppers can create a list by scanning packs at home or searching for a brand or product. When they enter the store the products will appear as dots on a map of the store. They scan and pack their items into their trolleys and can pay using their card on the app. Full details of how it all works are yet to be relieved but this again shows how mobile technology continues to revolutionise the shopping experience.
