NFC Tag For Food Safety

NFC Tag For Food Safety sticks to containers and change color when a food has gone bad. If a product was left out too long or stored improperly -- even if customers, grocery-store owners and manufacturers can't tell the difference without opening it and smelling it --the tag still gives a reliable indication of the quality of the product.
