(FR) CODE LISIBLE PAR UNE MACHINE
Abstract: front page image
(EN)A machine readable code (10) in the form of a matrix array of dots arranged in rows and columns represents characters by respective columns of m dots. Each column contains a repeated n-bit pattern and is such that no block of n consecutive bit positions occurs in the column representing any other character, all the blocks of n consecutive bit positions within a given column being related by cyclic permutation. The code reader (16) Spans more than n bit positions but less than a full column.
