Mark Your Food / Refrigerator product

In modern life, there is often a phenomenon that the expiration date of food in refrigerator is forgotten. So we mark the expiration date by twining the food with electrostatic tape with a series of QR codes on it,and scan the random QR code before placing it into the refrigerator, then set its expiration date on the LED screen placed on the refrigerator door. In the last three days before expiration, the screen will remind the user that the food should be eaten, the random QR code should be scanned again to clear the information of eaten food.This product,which is easier to use,is designed for low-end refrigerator merely with LED screen.
