Your NFC Ring has 1K of Storage, how would you use it?
-
Naturally one will be used to store Bitcoin but I already have been doing that for almost a year with my NTAG216 implants. (Google: Bitcoin Implant Man) I tried doing this with the first-gen ring but because capacity was limited I use that as an ICE (in case of emergency) telephone number. The implants are used as Bitcoin Wallets, NFC Keepass unlocker, snooze button for the sleep as android alarm clock (works great with the first gen ring too!) and to unlock the phone (only on my rooted droids though)
What we really want to explore is the possibility use the ring as an 'unlocker' or 'enabler' of smart-contracts as this is where the extra capacity will really come-in handy and both my NTAG216 implants and the first-gen ring just don't have the capacity to do that kind of magic. We can't wait to get hacking!
-
I would use it to keep my public encryption key, my name, and medical emergency information (In Case of Emergency, or ICE). If push comes to shove, the ICE would be the top priority.
I have one of the first generation rings, but could never really use it because, unfortunately, I'm a klutz and have to keep my devices protected in cases, etc. and the NFC won't reach through them... So, I'm definitely interested in this new ring.

Hey Guys
I use my current NFC ring for basing stuff. I change the using nearly weekly.
Normaly I use it to unlock my phone. Thats nothing special.
I was at the Gamescom. There I linked my little youtube channel as a short cut in my ring. And when people asked me what kind of channel I have I was like: Ok I show you something cool. Thats the easiest way to see what I make. Do your smart phone have NFC? I show you something cool.
And so I showed some people my Channel. Everybody said that they liked the method to show someone they stuff in the internet.But now I use my ring in my work. We have there a special room. Its locked with a NFC door. I talk a bit with my boss and now I can use my ring to unlock the door. Thats cool because I dont waste time to unlock the door with the chip on my keys :)
Here is a cool little picture of my ring ;)

Working in the security industry & specialising with Access control. I have found the NFC ring to be an added feature.
Having programmed multiple doors into the ring, I have removed the use of multiple access control cards & keys. The one ring controls all my access. Having been using it very successfully with the range of Salto products, & testing with other brands of locks. Hoping the new ring with the increase in range,will allow us to utilise the ring in our product range that did not respond to the original ring.Regards,

The first thing that I'd do is place full contact details on the public side because currently there are just too few bytes to fit more than email and one phone number. Private side I'd definitely like to be able to store encryption and access keys so that it can do more than just unlock my phone.
-
Off the top of my head, I'd be able to store additional and more complex cryptography keys...
The storage could be formatted to allow the use of cryptography keys with some storage for non-security related data.

Anything and everything, endless possibilities!

@Wojtek You win at life.

@Ben-Whorwood Holy shit this is awesome work man!

@johnyma22 I'd love to get multiple uses of information on them. See if there's a chance to create an nfc open standard for reading information using a simple scripting language. Most importantly I'd see if I could get NFC rings compatible with mozilla firefoxOs phones.
-
Given the better range of the new chip, I will get back to my project on desktop unlock. not so much a storage thing but a readability thing.

@johnyma22 Thanks!

Using the RFID module via the Arduino to write the contents of the NFC chip was pretty interesting and allows for completely customised (i.e. not using a standardised file system) data to be written onto the ring.
I wanted a barebones platform to use as a base for future projects and using an Arduino allows for so many possibilities (although anything with a HS UART / Serial connection can make use of the RFID module in the demo project (e.g. a PC with a serial connection or USB-Serial adaptor)).
Those who attended the talk and people I have spoken to afterwards have all been very impressed with the build quality and design of the NFC Ring. Quite a few developers saw a lot of potential for their products.

Definitely a ECDSA key or two...

hi group,
i would use it to store game data combined with the nfc game kids like my free system:
NFC Playing Figures / Lego´
where you can make interactive playing systems.or even with the new lego dimension system:
Lego Dimensions RFID/NFCSystemso it is possible to meet together and come to you playingstate with one short handmovement.
sunny wishes,
Alex
