Abstract
The present invention relates to a system and method for reading a two-dimensional array code. The two-dimensional array code comprises a plurality of equal-height code characters arranged into a two-dimensional array, wherein each of the code characters corresponds to a bit group representing information, and the adjacent code characters in the row direction of the two-dimensional array have equal center distances; and a locating mechanism, for defining size and/or direction of the two-dimensional array arranged by the code characters. The present invention greatly reduces the cost for issuing a two-dimensional code, and significantly increases the user convenience. This two-dimensional array code has high compatibility for user mobile terminals. In addition, the entire system apparently improves its safety and stability, and is suitable for the present network application environment.
