Hi,
Did you guys try to use your NFC Ring with contactless smartcard readers ?
The readers I have don't recognise mine.
I tried :

• Omnikey 5321;
• Gemalto Prox Du;
• Xiring DCR001 (SCM SCR331-DI Usb)

Thanks for your reply.

Hi,
I received my ring yesterday, and confirm that it works with my XPeria ZR.
The sweet spot is small, so I first thought the ring was faulty.
It's difficult to unlock the phone each time at the first try, but it works :)
