A two-dimensional code can contain a variety of information, the information code construction is simple and convenient, flexible and practical, high reading reliability, not only can prevent errors, but also has the ability to correct errors, not only read data with errors, but also through two-dimensional error correction method to complete the correct reading of information. At the same time, a certain amount of encryption can be carried out in the QR code.
