Abstract: A laminate includes: a first laminate member; a second laminate member; and a hidden print formed by printing invisible ink between the first laminate member and the second laminate member. The hidden print is configured to absorb electromagnetic radiation outside the visible range. When irradiated with electromagnetic radiation outside a visible range that has passed through at least one of the first laminate member and the second laminate member, the hidden print absorbs the electromagnetic radiation to thereby show a sign, and, when irradiated with visible light, the hidden print does not show the sign.

Abstract: An anti-counterfeit medium, a method for manufacturing the same and a method for preventing counterfeiting are provided. The anti-counterfeit medium includes a retardation layer having birefringence and a reflection layer, and identification data is recorded in the anti-counterfeit medium. The identification data is divided into a plurality of partial images, and a plurality of transparent areas which correspond to the plurality of partial images are disposed adjacent to each other in the same plane so as to form the retardation layer, the plurality of transparent areas having optical axes which are oriented in different directions from each other in a rotation direction. The identification data includes biometric information.
