HOLOGRAPHIC MATRIX, SYSTEM OF HOLOGRAPHIC IDENTIFICATION OF PERSONAL CERTIFICATES AND SYNTHESIS OF HOLOGRAMS WITH DESIRABLE VISUAL PROPERTIES AND METHODS OF THEIR FABRICATION Russian patent published in 2015 - IPC G07D7/00

Abstract RU 2569557 C2

FIELD: physics, signalling.

SUBSTANCE: invention relates to identification of identity cards. Identity card safety field comprises multiple image elements spaced apart within the limits of composite image to rule out overlap with the elements of the other set. Note here that said spacing and arrangement are preset definitely to make a safety key.

EFFECT: higher level of document protection.
