I had this idea that, I think, would be, hopefully, interesting for the community and maybe even the Nothing Team up in London (and around the world), called Nothing (Tag)
Nothing (Tag) is a tracker that works using different contact points such as BLUETOOTH and GOOGLE’S FIND DEVICE ecosystem. In concept, it is card-shaped which allows it to be stored easily and discreetly in a wallet while also having a tiny hole in a corner (or center) to be used as a key fob. Some similar devices are: Chipolo 
& Tesla Key.
It could have lights in the corners like the glyphs to help find it in the dark (activate when close to phone and prompted via phone). Also, additional features, NFC. Allow it to duplicate other NFC cards signals so it can be used as the emulated tag.
For example: I emulate my Bus Pass (which is an NFC card) and this allows me to keep my actual card home and only take my keys and the Nothing (Tag), which is attached to my key chain. (I do not know the possibilities of such, just an idea.)
Thank you for reading and give feedback please.
P.D.: No actual renders because I don’t know how to make good renders haha. Sorry.
