Advanced ATM Security System Using Arduino Uno

ATM machine is a great piece of technology used by millions of people around the world. It makes our daily transactions easier without loading up the banking systems However, it is important to keep them secure from thefts and other malicious activities. Traditional ATM system uses PIN (personal identification number) for the authentication purpose and nowadays smart card with magnetic stripes and PIN is in use. Thereby taking care of security from user's front. However, securing ATMs from bank's front needs a lot of work to be done. Merely deploying security personnel at the ATM is not enough. This project comprises an advanced security system that can monitor and activate various security measures in case of robbery and theft. This security system detects malicious activities inside the ATM booth. The security system check different parameters of the security and keep the concerned authorities updated. It uses sensors like Reed Switch, Ultrasonic Sensor, and Cameras to do so. If any unauthorized person is trying to move or open the ATM machine, due to reed switch, the circuit gets open. The ultrasonic sensor is used to sense to presence of intruder. If there is any change in these two parameters, the surveillance camera takes the picture and concerned authority is inform via SMS and can check the face of intruder via an IP address.
