Abstract
Abstract The present invention is concerned with a certification card such as ID card or the like including hologram and an optical recording portion. Hologram is such that an amplitude and a phase of light wave emitted from an object are recorded and an image of the object is rebuilt by emitting light to reproduce of an amplitude and a phase of the thus emmited light. one the other hand, optical recording technique is such that data pits are formed on an optical reflective surface of an optical recording layer and the thus formed data pits are detected by difference in optical reflectivity from the data pits when the object is lightened by laser beam so that data are read. According to the present invention a card is constituted by adhering a card front board to a card rear board, and hologram and optical recording portion are formed between the card front board and the card rear board.
