'''Grid Matrix Code''' is a 2D barcode symbology which consists of a square containing a matrix of smaller squares, each of which is a matrix of still smaller squares that are either dark or light. The code resembles a tiny chess board, since the squares in the matrix alternate between being dominated by dark and light colors. This symbology was designed specifically for use in encoding Chinese characters, since the entire [[GB 2312]]-1980 character set can be encoded, as well as [[ASCII]]. Extensive error correction is included.
