The main aim of our project is to implement the door lock system using the fingerprint sensor. There are many modern locks that replace the regular locks due to the high security, while we use this we are able to both lock (or) unlock the door lock using the fingerprint sensor. You are not supposed to carry the bundle of keys wherever you go, so that we can implement this idea and for the high security too. The possibilities of threats occurring in regular locks is less compared to the wireless biometric lock (i.e.) modern lock. Only a particular person can open the door lock (or) unlock it. It is not like the regular lock means if X person opening the lock using a key means the lock will release on its own. In modern lock there is no possibility that only the developer will open it, if someone wants to access using smartphone we should get verification from the user by getting the OTP and login the app.
