The design and implementation of a smart banking portal that mimics key ATM operations in a web-based system using PHP and MySQL. The system aims to mimic basic banking transactions like user login, balance check, cash withdrawal, and mini -statement creation in a safe and convenient platform. The backend is driven by PHP, supporting dynamic content rendering and secure session management, while the MySQL database manages user data and transaction records with real -time precision.The architecture of the system focuses on modularity and scalability to enable simple maintenance and possible feature extension. User interactions are securely handled by encrypted sessions and form validations to maintain data integrity and reduce risks of unauthorized access. Admin-level access is also included to track transactions and handle user information efficiently.This project illustrates how open -source technology can be used to mimic sophisticated financial transactions that are normally performed by physical ATM machines. By emulating a software version of ATM services, the system provides an efficient and low-cost solution that can be enhanced for instructional, research, or deployment intent in small financial institutions. Future development can involve the addition of biometric authentication mechanisms, responsive mobile interfaces, and encryption methodologies to enhance system security and user satisfaction
