Base Claim:
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.

Claim 3:
3. The method according to claim 1 , wherein the physical structures include one or more so-called control/extension columns and a value column, while the computing structures include as many bytes as there are columns, wherein the physical structures defined by 2 columns at least one is value and at least one is control/extension, these structures comprising: 2 dots reserved for the extension of the coding of the value coded by the value column, 1 dot characterising the parity of the number of its own black dots, 1 dot for the parity of the number of black dots in the value column, 1 dot specifying the parity of the number of segments formed from black dots in the value column, 1 dot giving the state of the first dot in the value column, 1 dot indicating whether the present column is the last of the character or whether the following control/extension column also forms part of it, and the value column being formed by dots generally weighted to a power of 2 increasing from 2 0 as from the header.
