I lost a bunch of keys today. It sucks and it’s gonna cost me a lot of money to replace the locks. I want to to add an airtag-like device to my key ring in the future. However I don’t know of any device that works in a similar fashion, either through bluetooth or GPS, that works with Graphene and doesn’t require some kind of privacy invading online subscription.
Do you have any advice on privacy respecting alternatives to airtags?
Sounds kind of like UHF RFID, which are common in places like warehouses and can be done at a distance, but even higher frequency?
I imagine range was a huge issue. Unless you have an extremely powerful bluetooth tranceiver and a very high gain antenna (i.e. not a phone, a professional radio system), the inverse square law will mean you won’t have enough energy to activate the electronics in the tag after a fairly short distance. Would probably work for finding something in your house though.
