Samsung’s UWB tech will let you use a Galaxy Note 20 Ultra as a digital key

To start with, you’ll be able to use Samsung’s UWB tech to share files with others who also have UWB tech. “By simply pointing Galaxy Note 20 Ultra to other UWB equipped Galaxy devices, Nearby Share will automatically list the people you’re facing on to the top of your sharing panel,” Samsung said. From there, you’d be able to send photos, videos and other files over Bluetooth, WebRTC or peer-to-peer WiFi, whichever works best under the circumstances.

What’s more intriguing is what it’s capable of. “Future UWB functionality will also help you find things more accurately with AR technology and unlock your home as a digital key,” according to Samsung. During its Unpacked 2020 presentation, Samsung specifically cited Assa Abloy — the company that manufacturers Yale and August Home smart locks.

As detailed by the FiRa Consortium that manages UWB, it could also indoor location tracking inside a mall, for instance. For now, it has limited use with Nearby Share, but it sounds like companies are just scratching the surface of UWB’s potential.
