▎ 摘　　要

NOVELTY - The security feature apparatus has a graphic code disposed on a graphene nanocomposite material layer. The graphene nanocomposite material layer comprises a layer of graphene disposed on an adhesive layer. The graphic code is a Quick response code or a barcode. The graphene in a layer of graphene is present in a pure or a doped form. USE - Security feature apparatus for providing security feature against counterfeiting for high-value products, such as food, cosmetics and drugs. ADVANTAGE - The security feature apparatus has a graphic code disposed on a graphene nanocomposite material layer, and hence ensures simple and reliable security feature apparatus. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for authentication of an item; and (2) a product authentication system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the use of the security feature on the packaging of a high-value product.
