Smart food delivery system is designed to save time of waiting in the restaurant or in front of the food truck. This is how it works: users can order the food in advance by our app, and it will generate a QR code. When the restaurants receive the order, they can start cooking before the busy lunch/dinner time. As long as the meals are ready, they can deliver them to our smart food storage box. Use the QR code associated with the meal to open the smart food storage box. If the dish is hot, our storage box will automatically turn the heater on. When it's dark or night, the LED inside the box will turn on automatically. Therefore, food can be placed in the box safely, freshly, and warmly if it needs. After that, user can pick up the food whenever he/she wants with the QR code to open the box.
