The QR code is also called the two-dimensional bar code, records the data symbol information in a black and white pattern distributed in a plane (two-dimensional direction) with a certain geometric pattern according to a certain rule; skillfully uses the code to compose the internal logic foundation of the computer. The concept of "0", "1" bit stream, using a number of geometric shapes corresponding to binary to represent literal value information, automatic reading by image input device or photoelectric scanning device for automatic information processing: it has bar code Some commonalities of 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 functions of automatic identification of information on different lines and processing of graphic rotation changes.
In recent years, some auto parts manufacturers have reflected that traditional character graphic labels can no longer be satisfied with the daily labeling of products, and currently tend to be more anti-counterfeit QR code labels, China Perfect Laser has learned that all parts manufacturers have been in accordance with heavy truck standards. Labeled with two-dimensional code; this approach greatly improves the authenticity and traceability of the product.
