ATM Interface System

Description:

An ATM (Automated Teller Machine) Interface System is a software simulation or design that allows users to interact with an ATM for tasks like withdrawing cash, checking balance, transferring funds, and more. It provides a simple interface for users to perform banking transactions securely.

Features:

1. User Authentication: Secure login using a PIN (Personal Identification Number).
2. Balance Check: Display the current balance of the user’s account.
3. Cash Withdrawal: Allows users to withdraw money within their available balance and withdrawal limits.
4. Fund Transfer: Enables transferring funds between accounts (within the same bank or to another account).
5. Mini-Statement: Prints a brief statement of recent transactions (last few transactions).
6. Deposit: Users can deposit cash into their account (if the interface simulates deposit functionality).
7. Change PIN: Option for users to change their PIN for security.
8. Transaction History: Users can view their transaction history and past activities.
9. Error Handling: Inform users about insufficient funds, incorrect PIN, or any other errors.

Requirements:

1. Programming Languages:
   • Java, Python, C# for the core application logic.
   • SQL for managing user accounts and transaction data (if connected to a database).
2. GUI Frameworks:
   • Java Swing or JavaFX for graphical interfaces (Java).
   • Tkinter (Python) for basic GUI, or PyQt for more advanced interfaces.
   • Windows Forms or WPF (C#) for the user interface.
3. Database: MySQL, PostgreSQL, or SQLite for storing user data, transaction history, etc.
4. Security: Encryption for storing PINs, SSL/TLS for network communication (if remote).
