At present, QR codes are mainly applicable to mobile payment, so our National Payment and Clearing Association issued the "Barcode Payment Business Specification" to various payment institutions, which clearly pointed out the security standards that payment institutions need to abide by to carry out barcode business, which is also a guarantee We are more secure in our daily use of QR codes. And we must also establish awareness of prevention, improve the understanding of QR codes, use QR codes correctly, and pay attention to protecting payment codes when shopping and paying, so that QR codes can bring more convenience to our lives.

With the development of science and technology in our country, our country is also developing our own "2D code" - Hanxin code. On July 28, 2021, the ISO international standard project of Hanxin code was unanimously approved. On August 27, the ISO international standard ISO/IEC 20830 "Information technology — Automatic identification and data capture techniques — Han Xin Code bar code symbology specification" (Information technology — Automatic identification and data capture techniques — Han Xin Code bar code symbology specification) Officially published. This is an independent research and development of our country, and compared with other 2D codes in the world, Hanxin code is more suitable for the representation of Chinese character information and can accommodate more information.
