I got my Kerv ring a few weeks back. Actually, I got it a few months back but initially it was the wrong size, then they sent the same size, and finally I got the ring. It works. And it works most of the time. It can be a bit hit and miss at times. But my current success rate is 80% roughly.
It will mostly come down to weather or not the tag is writable. which we wont know until @johnyma22 is allowed to tell us.
The Samsung door lock I have just reads the tag ID, it doesn't write anything onto the tag so in theory it should be fine. Same for an android unlock screen.
The Windows unlock app on the other hand writes an encrypted text string into the ring, so if the ring is not writable this will not work.
I am of course not a tester and making assumptions of compatibility.
bumping an old topic but worth it
i agree with @Lokki older comments.
i myself have never actually seen a confirmed case of rfid skimmed data being used to preform a transaction
every single story i hear is prefaced with
"i know someone who"
@Andreas sorry for my English.
Yes I meant about it, the Rio's Visa Ring... Then, if I buy it, how could then use it in Spain?
Or when could I use it?
Thank y for your help.
Ps: am I in the wrong blog?
If you're asking, "can it be used to make payments with BitCoin", then the answer is yes - I use mine as my BTC wallet.
If you want to make a paypass/paywave/swipe'n'go payment like your credit card then there's another thread you should be watching.
Note that this is a new NFC Ring, not one of the NTAG variants.
Hi, I've deleted one of your posts because double-posting is a little pointless.
At the moment the NFC Ring isn't set up to perform payments, though you could conceivably put your bitcoin receive address in and use it that way.
In the future there may be something publicly available to make payments with, but it hasn't been made yet.
I don't believe it was hacked in the end, certainly can't find any follow up on it.
The ring is readable from an extremely limited distance, don't fall into the trap of thinking of it like just another NFC tag.
