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.
The Vending Fridge knows the exact quantity and type of products that are inside and figures out what the consumer removes from, or returns to, its shelves. Through wireless communication, it then updates accounts and instantly automates billing. All merchants have to do is keep the fridge stocked. The system keeps track of stocks as they get low and sends monthly remittances to shop owners with the revenue generated minus a fee that ShelfX keeps. The Vending Fridge is aimed at hotels, retail stores, gyms, schools, libraries and other locations where flexible food vending is needed. It is available to pre-order for $599, or a retrofit kit is available to DIY owners for $299.
