It seems that Sectors 1 - 4 (UID and other things) are not writable. The UID is factory locked.

Will it ever be considered for NFC Rings to be sold with Sectors 1 to 4 completely writeable? It would be nice to do a perfect clone of my existing smart cards.

The visual fail ring I have is 7.5 which suits my index finger, and although it's a bit difficult to take it off my middle finger, I tend to wear it on my middle finger. It is a 30mm all-black ring.

I am looking to buy the Alpha Signature... but its smallest size is 8. Will the 0.5 make a difference?

Hey Kelvin if you shoot an email into support we will look at getting you some working QA fails sent to you.

Awesome. There's an offer you can't refuse.
Thanks @NFCringTom.

Thank you so much for your help!

Hi @Lokki, I am unsure what my ring size is. I definitely know that the school readers read NFC, since they do react when I put NFC stickers and my Oyster Card against it.

The next hackathon I am going to will be OxHack < http://www.oxhack.co.uk/ >. Although NFCRing isn't sponsoring it, it would be nice to have a working one to integrate with whatever I make there. The guys I'm going with are just throwing around ideas at the moment, but I can definitely see a use for it in all of our ideas, from using it to make a phone call or for an in-app form of authentication.

Hi Lokki, the one I have is the smallest which was given out. One side is Vintage and the other side is Classic. I can confirm that the dedicated NFC readers around my school (locking doors, food payment, etc.) don't detect the ring... It sucks since I wanted to clone my smart card onto it so I could fist bump the readers to unlock the doors. Aside from the obvious use, I also wanted to try it out for Android development... I can see multiple uses for it.

Hi there. I received my ring at MLH Launch Hack. I tried building a hack for it, but it would simply not work on any of my phone or the phones of the people surrounding me. As this was gifted at a hackathon, am I ineligible for any replacements?
