RFID stands for Radio Frequency Identification and it’s a non-contact technology. They are used for the purposes of tracking, access control, supply chain management, books tracking in libraries, tollgate systems etc.,
In this project we have used RFID card which has 2 components, the tag which authenticates the user and the reader, which will be implemented in the door. Then we have used 180 degree servo motor which is fixed at the back side of the door along with a 3D printed lock system.
