ATM Security System using Arduino Uno and Fingerprint Module

The ATM Security System using Arduino Uno and a Fingerprint Module is an advanced security project designed to enhance ATM access control. This system integrates biometric authentication to ensure that only authorized users can access the ATM.

How It Works:

1. The fingerprint sensor scans the user’s fingerprint and matches it with stored data.
2. If the fingerprint is authenticated, the system grants access to ATM functions.
3. If an unauthorized fingerprint is detected, an alarm system is triggered, and an alert can be sent via GSM module.
4. An LCD display provides user feedback, while an Arduino Uno microcontroller manages the entire process.

Key Features:

✅ Secure and reliable biometric authentication
✅ Prevents unauthorized access to ATM functions
✅ Real-time alerts via GSM in case of unauthorized access
✅ User-friendly interface with LCD display
✅ Customizable for various security applications

This project provides a high-security solution for ATM authentication, reducing fraud and unauthorized access risks. It can also be expanded with additional security features like RFID, password protection, or face recognition for enhanced security.
