Any idea where the Stealth Bomber rings are in terms of production/shipping?

I came here to say this!

But my addition would be to have a context-dependant password i.e. it takes the NFC hash, then takes the first 3 letters of the web domain (or similar) you're accessing and spits out a new hash.

This would reduce password redundancy if your password was compromised on one site.

When on android you can often use the 'Share' function to send the link to a friend or broadcast to social media (I'll deal with photos/videos in a minute).

Obviously you can't encode anything on to the ring, but I think we could use this functionality to 'Share' the link to a database (or just an online hosted text file public or a google drive one line .txt) assigning a NFC Ring hash to a url.

-This is an interesting article, I'll save it for later
-Share to: NFC ring [prompts you to put your ring to the device]
-Phone updates database with Ring hash code and a url
-i.e. 68CASH93FIN9Q982FOIAFNOI310FN http://www.bbc.co.uk/news/world-us-canada-23610105
-Time passes
-Oh Hai Mark, let me show you this cool story I saw earlier! bumps ring to phone/device, url is pulled down.

Obviously this kind of thing could also be done via a hundred other apps more instantly but I'm thinking of more long-term storage.

This would work by having the Share to NFC bump upload the photo/video/whatever to somewhere with a public/private url depending on your preference, which I would personally do with Google drive integration for hosting. This would then also update the hash-link database.

This would also have a set up for people who don't want to regularly move things around, but want a photo/video tied to their ring. It would be permanent until you want it not to be!
