Our research paper presents a comprehensive approach to developing an offline banking system that includes multi-factor authentication and face recognition technology to enhance the security and efficiency of traditional banking systems. It includes a thorough review of the changing trends in the banking industry due to technological advancements and highlights the workings of traditional banking systems. The proposed system comprises four main components, including an authentication window, a main window, a face recognition algorithm, and a user file system. Detailed results from the testing and implementation of the prototype are provided, indicating that the proposed offline banking system can significantly reduce paperwork while improving the accuracy and efficiency of banking transactions. The findings, with a notable face recognition accuracy falling within the 80–90% range, demonstrate the potential for enhanced customer satisfaction and reduced operating costs. The research suggests that this technology can be implemented in other industries to enhance security and reduce the need for manual verification, ultimately leading to increased productivity and cost-effectiveness. The proposed system can be a vital tool for banks to maintain their competitive edge in the industry.
