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?
I think you must be confusing things or were told a lie. Bluetooth is a standard that is definitely not designed to be able to work like that. NFC is designed to work with thin tags that don’t have a battery. Essentially they get power wirelessly from your phone in order to be able to send information. But, due to the inverse square law, you would need extreme amounts of power to be able to do that over a long range, so it just isn’t something that could work with mobile phones.
