PURPOSE: A certificate for a chipless RFID and a method for authenticating the same are provided to improve the reliability of the certificate by matching IDs from metal fibers and IDs from an authentication code printing layer. CONSTITUTION: A printing layer(110) comprising an authentication detail is printed to an object(100). A transparent resin layer(120) comprising dispersed metal fibers is printed on the object or the printing layer. An authentication code printing layer is separated from the transparent resin layer and printed the object or other part of the printing layer. If a reader projects a microwave to a transparent resin layer, a reflected wave of a specific waveform is created in the metal fibers. |
