The financial landscape has dramatically shifted with the rapid adoption of digital technologies and the increase in online transactions. While these advancements have provided significant opportunities for banks by streamlining operations and improving customer experiences, they have also introduced substantial challenges, particularly in fraud detection. The methods used by fraudsters have become increasingly sophisticated, necessitating more robust and adaptive detection systems. This paper explores how emerging IT technology including blockchain, quantum computing, biometric authentication, machine learning, and artificial intelligence, are revolutionizing fraud detection in the banking sector. It also discusses the importance of collaborative efforts, customer education, and the adoption of innovative strategies to keep up with changing fraud strategies. The study aims to provide a comprehensive overview of these technologies and trends, highlighting their potential to enhance security, operational efficiency, and customer trust in the digital age.
