2-dimensional bar code is a black and white graphic that records data symbol information in a plane (two-dimensional direction) with a certain geometric pattern; it is cleverly coded. The concept of "0" and "1" bit streams constituting the logic of the internal logic of the computer is used to represent the literal numerical information by using a plurality of geometric shapes corresponding to the binary, which are automatically read by the image input device or the photoelectric scanning device. Automatic information processing: It has some commonalities of bar code technology: each code system has its own specific character set; each character occupies a certain width; it has a certain check function. At the same time, it also has the function of automatically identifying different lines of information to facilitate our daily life.
