BoodFood is a network of smart fridges and unmanned micromarkets that sell food and drinks with no shop assistant — in offices, factory halls, dorms, gyms, and other places where people gather. The customer unlocks the fridge via an app or a card, takes what they want, and the system recognizes what was removed and charges for it automatically, thanks to a mix of RFID tags, weight sensors, and AI cameras. It differs from a classic vending machine in that you shop from an open shelf with no buttons or hatches — grab and go, like in a small self-service store.
