Smart Door Locks

>A smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key to execute the authorization process. Smart locks, like the traditional locks, need two main parts to work. The lock and the key. Smart locks allow users to grant access to a third party by the means of a virtual key. This key can be sent to the recipient smartphone over standard messaging protocols such as e-mail or SMS.
