Allow people to interact with connected accessories in completely new and exciting ways by leveraging the Ultra Wideband (UWB) chipset in a supported iPhone or Apple Watch. The Nearby Interaction framework makes it easy to integrate UWB in your apps and accessories.
Build apps that interact with accessories simply by being in close proximity to an Apple UWB-enabled product. Taking advantage of UWB allows you to create more precise, directionally aware app experiences.
Use the Nearby Interaction accessory protocol and an MFi-certified UWB solution to manufacture accessories that interact with UWB-enabled Apple products.
