BIOMETRIC ASSISTED SMART CARD FRAME WORK FOR SECURE CAMPUS ACCESS AND CASHLESS PAYMENTS

This work presents a prototype of a biometric-assisted smart card system developed to improve security and simplify daily operations within a campus environment. The proposed framework combines fingerprint authentication with contactless card technology to ensure that only authorized users can access services and facilities. A fingerprint sensor is used to verify user identity, while an RFID-based smart card system enables quick and convenient interaction across different campus services.The system is built around a compact processing unit that coordinates all operations and manages data flow between components. It is designed to operate in multiple modes, including classroom access, library management, and canteen payments. Users can switch between these modes using a simple interface, and additional verification methods such as password entry are included where required for enhanced security.For library and canteen applications, RFID cards are used for identification, making transactions faster and reducing manual effort. A thermal printing unit is included to generate instant receipts for transactions, improving transparency and record-keeping. All components are powered through a stable low-voltage supply to ensure reliable operation. Overall, the system offers a unified and efficient solution for campus management by combining biometric verification with smart card technology. It aims to reduce unauthorized access, minimize manual processes, and provide a seamless experience for users across different campus service
