Haven’t done the research but I wonder if you can use this to piggyback with tiny arbitrary data data payloads.

Yup, there was a project recently that used the airtag network to transmit data from a hardware keylogger. The computer could be totally gapped and the data still gets home via the typist's iPhone.

Earlier quoted context omitted.

They make super-thin AirTag compatible cards that fit in wallets.

I’ve even seen some wallets with built in “Find My” support.

Kindle cover would be extremely useful.

This is amazing. I love Apple AirTags but they are so bulky and an odd shape. I would love a AirTag the shape of a credit card to go into my wallet. I would love a smaller AirTag to go on my cats collar.

The ones I’ve seen don’t have precision finding, but yes. Some even have wireless charging.

I am guessing this is the story: Keylogger leaks data via Apple AirTag network https://news.ycombinator.com/item?id=38126302

I saw someone use this to track his mail state. They have a contact sensor inside their mailbox that rotates the broadcasted key based on the trigger count.

If the key changed, aka a new different device is visible, you know mail has been dropped in, very clever !

It's not airgapped if it has bluetooth access.

Presumably you stick the bluetooth antenna in the physical keylogger.

Looking through the code, it looks like this uses your personal Apple Mail entitlements to pull the locations that get collected by devices on the FindMy network:

I wonder if this were also possible by making an Apple developer account.

A Kindle or cover with Find My support would make my wife overflow with happiness.
