Abstract
A machine readable binary code includes a two-dimensional matrix of data cells (6) having a plurality of sides. A unique sub-array of data cells (1, 2, 3, 4) is positioned at the point of intersection of each pair of adjacent sides to define and uniquely identify each corner of the matrix.
