Abstract
A method of decoding a coding pattern disposed on a surface of a substrate. The method comprises the steps of: (a) operatively positioning an optical reader relative to the surface and capturing an image of a portion of the coding pattern, the coding pattern comprising: a plurality of merged data symbols, each merged data symbol being represented by a plurality of data elements disposed on the surface, wherein each merged data symbol encodes a first individual data symbol from a first codeword and a second individual data symbol from a second codeword; (b) sampling a set of the merged data symbols contained in the imaged portion; and (c) decoding the sampled set of merged data symbols to obtain the first codeword encoded by a corresponding set of first individual data symbols.
