Secure and Assistive UPI Transaction System for Visually Impaired People

Abstract

Android-based mobile application presents a digital payment solution specifically for visually impaired users. Conventional UPI apps pose a significant challenge due to their reliance on visual elements. This solution addresses by integrating assistive technology for more independent and secure transactions. The application features voice-guided navigation, which leads users through each step of the transaction via audio prompts. For secure access and quick payments, the solution has incorporated biometric authentication and a QR code scanner. This approach enhances the overall user experience while maintaining a high level of security, aligning with the principles of inclusive design in financial technology. Developed with Android Studio, the application utilizes key libraries such as ML Kit for QR code scanning and AndroidX Biometric for fingerprint authentication. The solution employed a modular development strategy, allowing each component to be independently tested for reliability and performance. Extensive unit, integration, and functionality tests demonstrate that the application meets the necessary usability and security standards for financial technology designed for users with visual impairments. This project contributes to accessible digital finance by enabling the visually impaired to perform UPI transactions autonomously. Future work involves adding support for regional languages and integrating AI-based voice recognition for more intuitive command input.
