This is just a model of automatic door lock. It works just like your metro card. When a valid card is brought in front of rfid card reader the door lock open and when an invalid card is brought in front of it door lock is closed.

It can be used in many ways. I had uploaded its code and also a video of my channel showing you how it works.
