Walnut Lock

Walnut lock turns your mobile phones to keys.

Walnut smart lock is very easy to use and secure. Users only need to scan the provided QR code, and then their smart phones become the keys to locks. As long as users get close to the door with their phones and press the door bell button, the lock will be unlocked. It is so convenient that users don't need to take out their mobile phones. In addition, users can query the locks for the unlocking history to know who enter the house and when. Users can also share e-keys with friends so that their friends can get in without trouble. The battery can last as long as two years, so users do not have to change frequently. More functions are welcome to experience.
