1. a two-dimensional code generation method, including:

  • Obtain upper layer application data;

    Judge the Quick Response Code capacity applying size of data the most corresponding more than described upper layer application data;

    If it is, data are split into data sectional and sorts, data sectional is carried out upper layer information coding;

    If it is not, described application data are directly carried out upper layer information coding;

    Generation upper layer information encodes, this upper layer information coding includes;

    splicing symbol region and Information Data Area, described splicing symbol region includes splicing bar number mark, group Quick Response Code mark and splicing order, described group of Quick Response Code mark is for identifying the one group of Quick Response Code needing splicing, and the same group of Quick Response Code needing splicing distributes a same group Quick Response Code mark;

    Upper layer information coding is carried out Quick Response Code coding, generates Quick Response Code.
