Abstract
The encoding mark uses a series of shapes as a guide, each of shape capable of being encoded with a finite number, including zero, of distinctive markings. The encoding of a predetermined identifier is performed by placing a predetermined number of distinctive markings substantially on the perimeter of at least one of the shapes in any spatial orientation with respect to each other on the series of shapes. The predetermined number of distinctive markings and the specific one of the shapes on which the distinctive mark is placed corresponds to a predetermined identifier. Since the shapes may only be a guide, they are not required to appear on the object marked with the encoding mark.
