1. A method of coding information comprising; creating sets of independent structures of any size, including elements carrying information allowing the identification and descriptive and functional control of structure of the elements; defining links with other structures; creating the structures to further include characters representing conjointly the information on a physical medium by dots and in computing format by bits; creating the structures of the physical characters which comprise on the one hand detection or marking dots that are peculiar to the physical characters and on the other hand dots which each correspond to 1 bit in computing format; and creating as mixed dot which is half white and half black.

The method according to claim 1 , wherein the third column of the characters of 3-column definition comprises: 1 dot characterising the parity of the number of its black dots, 1 dot indicating whether the present column is the last of the character or whether the following control/extension column also forms part of this character, 1 dot expressing the linking of the properties or independence with the following control/extension column, 1 dot specifies the parity of the number of segments of black dots of the previous control/extension column, 4 dots reserved for the extension of the coding of the value coded by the previous columns, and the first two columns being identical to those of the characters defined on 2 columns.
