Two-dimensional bar code/two-dimensional bar code (2-dimensional bar code) uses a certain geometric figure to record data symbol information in a black and white pattern distributed on a plane (two-dimensional direction) according to a certain rule; in the code preparation skillfully Using the concept of "0" and "1" bit streams that constitute the internal logic of the computer, several geometric shapes corresponding to the binary system are used to represent the text value information, and the information can be automatically read by image input devices or photoelectric scanning devices. Automatic processing: It has some common features of barcode technology: each code system has its specific character set; each character occupies a certain width; it has a certain check function, etc. At the same time, it also has the function of automatically identifying different lines of information, and processing graphics rotation change points.
