Patent ID: 8144922

Claim:
A method for generating a two-dimensional code with a logo, comprising: superimposing the two-dimensional code that represents information using a cell dot distribution pattern formed by having a plurality of colored cells on a visually recognizable logo mark; superimposing a cell dot whose brightness is lower than a predetermined brightness on a part of the logo mark whose brightness is equal to or higher than the predetermined brightness; and superimposing a cell dot whose brightness is equal to or higher than the predetermined brightness on a part of the logo mark whose brightness is lower than the predetermined brightness such that information is represented by means of a distribution pattern of the cell dot whose brightness is equal to or higher than the predetermined brightness and the part of the logo mark whose brightness is equal to or higher than the predetermined brightness, and the cell dot whose brightness is lower than the predetermined brightness and the part of the logo mark whose brightness is lower than the predetermined brightness, and wherein the cell dots which form an information pattern are printed with transparent infrared absorbing ink, the logo mark comprising a letter part, a diagram part and a background part, wherein, when the letter part and the diagram part are superimposed, only the cell dots of the letter part and the background part are printed with the infrared absorbing ink.
