Smart Door Lock System for ATMs

In recent times, security has become one of the most important aspects of people’s and companies’ lives. The Smart Door Lock System for ATMs is designed as a secure and flexible mechanism of access control using Arduino Uno and RFID technology, where the system locks a door when a registered RFID card is presented to give restricted access to authorized personnel; otherwise, it unlocks the door when an unregistered card or other objects are sensed, offering controlled flexibility to external users. The system also has a manual override feature in case of emergencies. This project provides a highly reliable, cost-effective and scalable solution for replacing a locking mechanism, making it pretty suitable for ATM facilities as well as other secured environments.
