in fig2 the hologram foil 1 is formed by laminating a bonding layer 2 for the surface of an object x a high polymer cholesteric liquid crystal layer 3 serving as a reflective layer a hologram forming layer 4 and a protective layer 5 and is adapted to be transferred onto the object x by the protective layer 5 serving as a peel layer separating it from a base film not shown in the drawing by heat and pressure during the hot stamping process referring also to fig3 and 4 the identification device 10 is provided with a centrally located light source 11 for emitting a random light beam and a pair of light receiving units 12 a and 12 b located at symmetric positions with respect to the light source 11 a circularly polarizing filter 13 consisting of a polarizing filter 14 and a quarter wave plate 15 is placed between the hologram foil 1 and one of the light receiving units 12 a at the time of identification or only in front of one of the light receiving units 12 a additionally a pair of band pass filters 17 are 18 for passing only light of a prescribed wavelength for instance only green light are placed in front of the circularly polarizing filter 13 of one of the light receiving units 12 a and in front of the other light receiving.
