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

As rumored, the flagship Galaxy Note 20 Ultra is Samsung’s first phone with newfangled ultra wideband (UWB) technology first seen on Apple’s iPhone 11. Samsung calls it Nearby Share, and it lets you point your Galaxy Note 20 Ultra at another Note 20 Ultra or future Samsung UWB device. It’ll then list all of those other devices or people at the top of a sharing panel.
