Oftentimes, we need to secure a room at our home or office (perhaps a secret dexters laboratory) so that no one can access the room without our permission and ensure protection against theft or loss of our important accessories and assets. There are so many readymade security systems present today but behind the scene, for authentication they all relay on fingerprint, retina scanner, iris scanner, face id, tongue scanner, RFID reader, password, pin, patterns, etc. Of all the solutions the low-cost one is to use a password or pin-based system. - Nilanjan Roy
