When the consumer came upon something they liked in the store, they pointed their device at it. The shelves, which were equipped with augmented reality, when communicated their contents to the device.
The information on the app was updated in real time, complete with information such as price and expiry date. As soon as the shoppers had filled their virtual baskets and were ready to check out, staff would collect each item for them, and process them.
