1. A method for encoding information, comprising the steps of:

  • providing a plurality of modules at predetermined locations in a symbol, each module coded with information;

    centering a finder pattern at a first reference point in the symbol;

    arranging at least one any-point-detection shape in a geometric relationship with the finder pattern and certain of the modules, wherein the at least one any-point-detection shape is detectable using a probabilistic algorithm and is provided as an alignment pattern;

    providing position patterns in proximity to groups of modules, whereinthe location of the finder, position and alignment patterns in an image of the symbol identify the location of the plurality of modules in the image, andthe modules are distinguishable by shape from the finder pattern, the alignment pattern and the one or more position patterns.
