A smart lock is a product that monitors who enters and leaves the home, and also assists with opening/closing, unlocking and locking doors. Doors can be locked and unlocked from a smart phone.
How do I use it?
Instead of spending minutes searching your bag for your keys, aiming at the keyhole and turning around the cylinder, all you need to do is tap your phone, and the door will unlock itself so that you can enter your home.
