Abstract

The article explores the global experience of fraud prevention and service quality enhancement in international bank payment systems. It emphasizes that digitalization has fundamentally transformed financial infrastructure, while simultaneously increasing exposure to cyber risks and fraud. Drawing upon the analytical framework of AI-based monitoring, blockchain immutability, and integrated risk management, the study examines how major international banks—such as JP Morgan Chase, Standard Chartered, N26, and DBS Bank—have adopted advanced technologies to ensure operational resilience and transparency. Statistical data from McKinsey (2024) and Statista (2024) demonstrate that global digital payment volumes reached USD 9.8 trillion in 2024, whereas fraud-related losses exceeded USD 42 billion. The analysis underscores that artificial intelligence and blockchain now serve as dual safeguards in modern banking ecosystems, balancing real-time fraud detection with seamless customer experience. The findings conclude that the sustainability of global payment systems depends on the integration of technological innovation, regulatory harmonization, and user-centric trust frameworks.
