Smart locks do not use a physical key to unlock the door but a smartphone or a purpose-configured smart card or key fob that performs wireless authentication for unlocking the door.
A smart lock is an electromechanical lock that is upgraded to perform locking and unlocking operations on a door when it receives instructions from an authorized device (smartphone) using a wireless protocol and a cryptographic key.
Smart locks can be considered as part of a smart home. Smart locks, like traditional locks, require two main parts to work: the lock and the key. With these electronic locks, the key is not a physical key, but a smartphone or a purpose-configured smart card or key fob that performs wireless authentication required to unlock the door.
Smart locks allow users to grant access to a third party by means of a virtual key. This key can be sent to the recipient’s smartphone via standard messaging protocols such as email or SMS.
Smart locks can also be called hybrid locks because they combine mechanical, electronic and wireless technologies in one package. Many customers like the idea that there are so many possibilities to customise the residential or business environment safer and smarter. Hybrid locks can combine a fingerprint scanner, palm reader and facial recognition with the keyboard (to use passwords), card readers and mechanical backup key. The latest innovative models come with a video camera built into the handle of the lock, allowing home or business owners to see the visitor on the smartphone screen.
