Through IoT (Internet of Thing), this fresh food system is able to let workers order food online and pick it up after work. Traditional vendors can estimate the quantity of the orders when they purchase. When they're selling food, they can make sure there won't be any in stock. At the same time, it can keep the hospitality and the value of customized service. Considering the freshness, health and the balance design of demand and supply, we provide the consumers with a new and healthy choice!
