Is anyone working on a project to...

1) Mobile nostr client (e.g. Amethyst, Damus, Amber) to start

2) Import/Export private key/nsec to a NFC card (even simply stored clear text)

This still uses the native mobile apps for signing, but is creating some form of physical backup.

Now take this further, and yes you could incorporate nfc card readers for desktop and browser... how about cards preinitialized?

Yes, the creator will have those keys as well, but there are real world use cases where this is warranted. Organizations with key issuance and escrow comes to mind.

I know there's all kinds of pros and cons to unencrypted storage like this, ability to copy etc, Im just curious what, if any, projects are exploring naive approaches like this, easier to mass rollout vs actual physical signing devices.

My gut thinks this is wasteful, and that the real solution for custodial masses will simply be the same old custodial control we've had in the past. Im just not sure if global focus should be on identity issuance, self identity, self signing, or full sovereignty

What if it was not unencrypted storage? :)

yes with the obvious tradeoffs on passwords to decrypt and risks of forgotten when theres no escrow

uhh I mean a signing device

ok. thats cool too.

i imagine a world where i may have a few of these for different roles, and when i need to say.. sign a business contract, or access medical records, i use the appropriate card tied to an id dedicated to that purpose to sign with. And the rest of the time its just locked away

I was thinking if would be cool if you had a NFC ring that you wear.

the form factor is less important for the core capability, but does have tradeoffs on convenience, attraction. Make it a dull grey metal to reduce the likelihood of having your hand chopped off

Here some pie in the sky idea... You have a NFC ring that is trained on your bio-rhythm. If there's a severe change then it wont sign.

Even crazier, what if starting your car or unlocking your front door took a nsec signing..
