Access Control Door
Question:
How do electronic access control doors work?
I just want to know how the door opened or closed with the help of RFID tags?. Can any one briefly explain how it works?
Answer:
We are having RF ID tags loaded in our proximity cards. it Will transmit Ur ID tag number to the reader mounted in Ur door access system. after recognizing Ur tag number the reader Will send the authentication code to the access board added wit a micro switch. That micro switch Will activate a 12V relay mounted to the door system….. with the help of the relays the stepper motors connected to the door Will start working… according to the rotation of the stepper motor in clockwise and anticlockwise the door will be closed and opened automatically..
