I have been looking for a wallet tracker card that integrates with Find My and supports UWB based precise location similar to AirTags. Surprisingly, I have not found any so far. The likes of Chipolo and Pebblebee only seem to support Bluetooth based tracking, which is not very precise. It will tell you the general area where your wallet was last seen by an Apple device, but then you have to rely on playing a sound to find them. For contrast, AirTags let you find the item to the (almost) exact location.
Does anyone know if this is a restriction imposed by Apple? Or is UWB tech too expensive? Or too bulky to fit in a card form factor?
