Hexagonal information encoding article, process - assigns optical properties to individual hexagons by ordering, hexagons in predetermined sequence

摘要

The optically readable label (30) stores encoded information in the form of a data array of a multiplicity of information encoded hexagons (20) contiguously arranged in a honeycomb pattern, and having two different optical properties (e.g. black and white). The process assigns optical properties to individual hexagons in a predetermined pattern consists of ordering the hexagons (20) in a predetermined sequence and prints the hexagons (20) with two optical properties (e.g. black and white). A process for retrieving information creates an optical replica of the digital bit stream representative of the optical properties of the information encoded polygons, decoding that optical replica and retrieving the decoded bit stream.
