The project I want to implement consists of a more secure door / gate locking system. They can be opened using a tag, using the bluetooth application or obviously, using the master card. The purpose of the project is, in short, safety. The whole idea came to me sitting at home realizing that if I have to leave, I should always have the key with me, so why not just have the phone with which I can open any door I want without having 300 keys with me.

The device uses 2 ways of unlocking the door: RFID Lock and also the phone application. The phone application is unlocking it through a bluetooth module (HC-06) since i want to make it for iOS. The RFID module works using a tag that you can only set with a master card.
