Abstract:
(EN) A method of recording a large quantity of data by one code mark. Four bit indicating fields (2a, 2b, 2c, 2d) for denoting a binary number of four bits are provided on the surface of a card (1). One numerical value is recorded by indicating predetermined bit parts of the four bit indicating fields (2a-2d) with the same color, and plural kinds of colors are mixedly given to the four bit indicating fields (2a-2d).
(FR) Procédé d'enregistrement d'une grande quantité de données par une marque de code. Quatre zones (2a, 2b, 2c, 2d) indicatrices de quartets et destinées à indiquer un nombre binaire de quatre bits sont ménagées sur la surface d'une carte (1). Une valeur numérique est enregistrée par indication de parties de bits prédéterminées des zones (2a à 2d) indicatrices de quartets avec la même couleur et plusieurs types de couleurs sont donnés de façon mélangée aux zones (2a à 2d) indicatrices de quartets.
