Securing Financial Transactions: An Embedded Arduino-Based ATM Crime Prevention System with Real-time Data Processing and IoT Integration

This project proposes a Smart ATM Security System that incorporates Radio-Frequency Identification (RFID), Internet of Things (IoT), and ESP32 camera technology to enhance the security of Automated Teller Machine (ATM) transactions. The system enables users to block/unblock their RFID-equipped ATM cards through a mobile app. In the event of a blocked card being used, the system activates a buzzer at the ATM, sends instant alerts to the user's mobile app via an IoT cloud, and captures live images using an ESP32 camera. The system also includes GPS location tracking and a vibration sensor to detect ATM machine theft. The integration of these components provides a robust and proactive approach to safeguarding ATM transactions, ensuring prompt user notification and enhanced security against unauthorized access and theft
