🏦 Smart ATM System — Python + Machine Learning

A Python-based ATM simulation system with secure PIN authentication, transaction management, and intelligent fraud detection using Machine Learning.
Built to demonstrate banking logic, user data handling, and AI-powered decision support.

---

💡 Overview

The Smart ATM System is a beginner-to-intermediate level project that combines Object-Oriented Programming (OOP) and Machine Learning (ML) concepts to simulate a real-world ATM.
It allows users to create accounts, authenticate via PIN, deposit or withdraw money, and analyze transaction behavior using AI.
