Samsung reveals unique UWB-based smart door lock in partnership with Zigbang

Samsung has unveiled the world's first UWB-based smart door lock. The gadget, created in collaboration with Zigbang, lets you unlock your front door purely by standing in front of it. Typically, smart door locks require you to tap your phone against an NFC chip or use a smartphone app. Ultra-wideband (UWB) technology uses radio waves like Bluetooth and Wi-Fi for short-distance communications, with a high-frequency band enabling precise distance measurements and sensing the direction of the signal.

Other benefits of UWB include enhanced protection from hacking due to its short range. The tool is enabled via a digital home key added to your smartphone's Samsung Wallet. Additional features of the lock include the ability to notify members of your household via the Zigbang app who is unlocking the door. Plus, if you lose your phone, you could disable the digital home key using Samsung's "Find My Mobile" tool to ensure that an intruder cannot enter your home.
