Implementation of Multi-Account ATM Card using Embedded System

Abstract

ATM services have gained widespread popularity due to their unmatched convenience and adaptability within modern banking systems. The use of ATM cards extends across a range of transactions, including instant money transfers, cash withdrawals, balance inquiries, and retail purchases. This project introduces a fingerprint-based authentication system for customer verification to enhance security further. The primary objective is to develop a unified smart card ATM that can manage multiple bank accounts under a single card, thereby streamlining operations and reducing the costs associated with interbank transactions. Integrating smart card (RFID) technology and keypad access ensures that only authorized individuals can access the system. The user module provides an intuitive and interactive interface, allowing users to quickly log in, manage multiple accounts, and perform transactions seamlessly. While emphasizing security strongly, this system also offers improved convenience, operational efficiency, and user-friendliness, making it a valuable advancement in ATM technology.
