Under the guidance of the People's Bank of China and the National Financial Standardization Technical Committee, the international standard "Guidelines for the Security Framework of Third-Party Payment Service Information Systems" (ISO/TS 9546) formulated by the National Clearing Company was officially released recently, marking a new breakthrough in the internationalization of China's financial standardization. It is reported that the formulation of the international standard for the security framework of third-party payment service information systems led by the National Clearing Company is the second international standard in the third-party payment sector initiated by China. The "Guidelines for the Security Framework of Third-Party Payment Service Information Systems" (ISO/TS 9546) is not only a summary of the successful practices of Mobile Payments in China but also fully demonstrates the leading position of Mobile Payments in the international arena. The standard regulates aspects such as the security framework, design principles, and functional requirements for third-party payment services. Its implementation will help enhance the security of information systems, reduce payment transaction risks, safeguard user funds, further facilitate the development of cross-border business, and promote the healthy development of the payment industry.
