The self-service machine allows customers to buy products via a mobile app and QR code.

The ShelfX Vending Fridge is a self-service machine that allows customers to purchase products like beverages, fruit and sandwiches without having to go up to the checkout. The company combines QR codes, RFID cards, mobile apps and smart shelves to provide flexible food vending and inspire further self-checkout strategies. Customers can use the ShelfX app (which stores their account and payment information) to scan the fridge’s QR code with their phone. This unlocks the door and lets them remove any items they want to buy. An RFID-enabled XCard, which acts the same as the app, can also be scanned to open the fridge.
