• 💰 Cash deposit and withdrawal operations
• 💳 Account balance management
• 🧮 Dynamic loan calculator with multiple interest-rate tracks
• 📜 Real-time transaction history
• 🧾 Receipt generation
• 💾 Persistent data storage using SQLite
• 🖥️ User-friendly graphical interface
• 🔢 Custom ATM keypad and interface assets

🚀 Getting Started

Prerequisites

Make sure Python 3 is installed:

python --version

Installation

Clone the repository:

git clone https://github.com/eyadHaddad98/ATM-System-Python.git

Open the project directory:

cd ATM-System-Python

Run the application:

python main.py

On Windows, you can also use:

py main.py

🗄️ Database

The application uses a local SQLite database:

atm_system.db

The database stores the information required by the ATM simulator and keeps data available between application sessions. No external database server is required.

🔄 Application Flow

1. The user enters an account PIN.
2. The application validates the account.
3. The user selects a banking operation.
4. The transaction is processed.
5. Updated information is saved in SQLite.
6. The transaction history and receipt are generated.

🔮 Possible Future Improvements

• Password and PIN hashing
• Account lockout after repeated failed login attempts
• Improved transaction validation
• Multiple user roles
• Exportable PDF receipts
• Unit and integration tests
• Dark and light interface themes

⚠️ Disclaimer

This project is an educational ATM simulation. It is not intended for real banking operations or the storage of sensitive financial information.
