    Your NFC Ring has 1K of Storage, how would you use it?

      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.

                @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!

                    Some links to additional resources related to the demo project and talk I gave can be found here:

                    http://www.meetup.com/Cornwall-Digital/events/221752001/
                    http://www.slideshare.net/benwhorwood/marrying-a-penguin
                    http://tmp.mube.co.uk/zuul_nfc_security/zuul_lib.tar.gz
                    http://tmp.mube.co.uk/zuul_nfc_security/zuul_src.tar.gz

                    (Source code in the last two links.)

                    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/NFCSystem

                        so it is possible to meet together and come to you playingstate with one short handmovement.

                        sunny wishes,
                        Alex
