The invention relates to coding sign points high in capacity and high in robustness. The coding sign points comprise a positioning sign position, an initial sign position and coding positions. The initial sign position and the coding positions are evenly distributed on a circle the center of which is the positioning sign position. The positioning sign position is equipped with a positioning sign point. The initial sign position is equipped with an initial sign point. The coding positions are equipped with coding points. Different coding sign points are formed by a situation whether the coding points are arranged in the coding positions or not. The positioning sign point, the initial sign point and the coding points form a circle, and can be differentiated from each other in area. Compared with the prior art, the coding sign points have the beneficial effects that: 1, sign positions are easy to identify; 2, the coding capacity is high; 3, the coding positions that are on the same line with the positioning sign position and the initial sign position are equipped with the coding points, and the included angle between every two adjacent coding points is less than 180 degrees, so the uniqueness of angle identification is exhibited and the identification accuracy is improved; and 4, the decoding accuracy is greatly improved.

The invention provides a two-in-one commodity barcode which comprises a one-dimensional barcode printed on an object and consisting of bars and gaps which are arranged. The bars are divided into deep-color line segments and light-color line segments. The positions, or / and the number, or / and the lengths of the light-color line segments are converted into variable data including a commodity traceability code after being recognized by light-color line segment decoding software. The two-in-one commodity barcode avoids color digital printing, is suitable for monochromatic printing, can reduce equipment investment, can increase production speed, can reduce manufacturing cost, and it is not required to replace conventional laser scanner hardware. The commodity barcode of a commodity using the two-in-one commodity barcode has two functions including a commodity barcode and a traceability code.

The embodiment of the invention provides an identification code coding method, which comprises the following steps: determining at least two adjacent to-be-coded areas according to object information contained in a carrier object, wherein each to-be-coded region comprises m * n blocks, and m and n are positive integers, determining a coordinate correction block in each to-be-coded region, under the condition that the coordinate correction blocks in the current to-be-coded area are not distributed in the same column and the coordinate correction blocks in the adjacent to-be-coded area of the current to-be-coded area are not distributed in the same row, determining a direction indication block and a data storage block in each to-be-coded area, and adding corresponding micro-image units to the coordinate correction block, the direction indication block and the data storage block to generate an identification code corresponding to the object information.
