ATM Simulation Using C#

This project is a detailed ATM (Automated Teller Machine) simulation developed in C#, designed to replicate the core functionalities of a real-world ATM system. The simulation provides a secure and user-friendly environment where users can perform various banking transactions such as balance inquiries, cash withdrawals, deposits, and PIN changes.

Key features include a login system that authenticates users with a PIN, ensuring secure access to their accounts. After successful authentication, users are presented with an intuitive menu offering options to view account balances, withdraw specific amounts, make deposits, and change their PINs for added security. Error handling mechanisms are implemented to ensure accurate transactions, such as preventing overdrafts during withdrawals or ensuring proper format and values during deposits.

The simulation models an actual ATM with functionalities like tracking available balance, issuing receipts for transactions, and updating account details in real-time. The project also includes a database integration to store user account details, transaction histories, and log user activities for auditing purposes.

The interface is designed using Windows Forms, providing a clean and interactive graphical user interface (GUI) that mimics the look and feel of modern ATMs. The backend is implemented in C#, making use of object-oriented programming (OOP) principles to ensure scalability and maintainability. Error handling, validation checks, and secure data management have been prioritized to simulate a realistic and secure ATM experience.

This project showcases C#’s capability in handling interactive applications while demonstrating key concepts such as file handling, database management, and secure data transactions, making it a valuable tool for understanding banking simulations.
