In the invention, because the characteristic pattern in each first frame is formed by the characteristic pattern, and the types of the characteristic patterns which can be formed in the first frame are quite large, the sub two-dimensional code carrying different information can be obtained by changing the shape of the characteristic pattern in the first frame, and further the two-dimensional code provided by the invention can carry more information.
In each sub two-dimensional code, the first border of the sub two-dimensional code and the characteristic pattern of the sub two-dimensional code may be pure color (e.g., brown), and the characteristic pattern is connected with the corresponding first border, so that the identification is facilitated. Furthermore, the first frame of the sub two-dimensional code and the characteristic patterns of the sub two-dimensional code can be pure colors, so that the requirement on equipment for spraying and forming the sub two-dimensional code is reduced.

When the two-dimensional code is identified by scanning, four main control patterns are firstly identified, so that the position of the two-dimensional code can be positioned, then specific graphs of each sub two-dimensional code in the two-dimensional code are identified, and information carried by each sub two-dimensional code is analyzed.
For convenience of printing, each main control pattern is a completely black box as shown in fig. 1 to 3.
In the present invention, the number of the sub two-dimensional codes included in each two-dimensional code is not particularly specified. For example, in the embodiment shown in fig. 1, the two-dimensional code includes 12 sub two-dimensional codes. The 12 sub two-dimensional codes are arranged in a row and a column, each row of sub two-dimensional codes comprises 6 sub two-dimensional codes, and each column of sub two-dimensional codes comprises 6 sub two-dimensional codes.

In fig. 3, the lowermost black frame represents the verification control pattern, and the pattern above the lowermost black frame is the verification pattern.
In the present invention, there is no special requirement for the first characteristic pattern in the sub two-dimensional code, for example, as a preferred embodiment, the first frame is a square frame, and the first characteristic pattern is selected from any one or any several of the following figures:
a line segment connecting the upper side of the first frame and the center of the first frame (e.g., the graphic may represent binary code 00000001);
a line segment connecting the top right vertex of the first frame and the center of the first frame (e.g., the graphic may represent the binary code 00000010);

If even check is adopted, the check bit of 11000000 is 0, that is, 11000000 is formed, so that the check pattern does not include a line segment connecting the top left vertex of the fourth frame and the center point of the fourth frame, and only includes a line segment connecting the midpoint of the left side of the fourth frame and the center point of the fourth frame and a line segment connecting the midpoint of the right side of the fourth frame and the center point of the fourth frame.
