Abstract
The invention discloses a two-dimensional code and its decoding method and the printing publication for applying the two-dimensional code. Positioning dots located at four corners of code symbols in the two-dimensional code are larger than data dots. The code symbols are arranged repeatedly on the basement, including at least two identical code symbols. Adjacent code symbols share same positioning dots on their adjacent border. The decoding method comprises the following steps: reading the two-dimensional code by using a reading device, detecting the margin of each dot, obtaining an image of the closed border, selecting positioning dots; matching the positioning dots in a rectangle mode, grouping the data dots, reconstructing a matrix of data dots, and reducing codes according to an inverse process of codes layout in coding process of the two-dimensional code.
