Grid Matrix Code (GM)

GM Code（Grid Matrix Code） is a 2D coding system in square. The code graph consists of square macro modules and each macro module consists of 6*6 square unit modules. The Grid Matrix Code can save a certain quantity of data and provide error correction level for 5 users. Compared with all similar global techniques, the advantages of this technique rely on the following capacities:

1、Super Anti-defilement Capacity and Error Correction Capacity;
2、Super Strong Anti-deformation Capacity;
3、No dead points in the graphic barcode;
4、Large storage capacity, digital information coding via any computer.
