Meet the Noki: a smart door lock that lets you open it using your smartphone. It features Bluetooth & WiFi connectivity (using the Noki Bridge), which means you will be able to lock or unlock your door from anywhere. You will also be able to share access with your friends and family. The battery life lasts up to 10 months.
The Noki Smart Door Lock is easy to install. The developers rely on an end-to-end encryption mechanism for your protection. You can find out more on Kickstarter.
