The equipment is called fingerprint door lock and I learned that ,when installed, it makes you use your own fingerprint to unlock the door of your house if you misplaced your keys or worse if you lose them. Interesting isn’t it? This is a type of home security that helps protect you and your home. This can also be used by companies for loss prevention.
But I know what you are thinking right now. You are thinking somebody might copy your fingerprint, right? That is my concern too.
