I second the motion to work with Coinbase and BitPay. Both are reputable organizations with great service.

*payer, not payee.

It would be cool if the user could preset different gratuity amounts for different merchants.

@Callem This looks excellent, where are you at with this? Sorry about the lack of response as you can imagine things have been busy!

This would be awesome for the PRESTO card we have in Toronto as well, likewise for Octopus in Hong Kong, etc.

Perhaps you guys could partner up with them...?

Maybe multi-sign solutions can be interesting here? New wallets with this functionality is currently in beta, if I've read the news correctly.

ring-initiated Ripple/Stellar transfers?

hands me the decive to enter my PIN.

Would be great to avoid giving away the PIN to anyone looking. Or if the hardware is cloning. There may have been a bluetooth-based ring up for pre-order (Kickstarter?) with a display, which could solve some of this. But generally just pre-approving myself with a budget for coffee-places, another for lunches, etc would allow payments without PIN in these places.

Yeah, it's a more heavy duty tag in them, the most I can get out of it is that it's an NXP ic which is "blocked" from scanning by NXP taginfo.

Another option is to just store the keys on your ring and use them to interact with your mobile phone so your mobile phone never stores your private key

Sorry, but storing a complete private key on the ring is probably a bad idea. Since the merchant taking payments are surely funneling all payments via some bank or payment processor, they could just send your public ID and let the remote payment processor handle things. They could do an instant debit or even a delayed credit transaction. You could have traditional (and costly) option to dispute the transaction.

With banks testing contactless payments (NFC) for sums under 25EUR, the same could be done with NFC rings, but that would surely mean the ring must use other NFC chips and the whole process would probably get more expensive. The brave could perhaps dare to extract the active part of a Paypass and try to squeeze that into a ring. But it'd surely be illegal for the stores to receive a payment unless you have an unharmed card with your signature etc etc. So, trouble.

Good to see other people/groups getting excited about that!

Not entirely surprising though. I think I've used NFC for all but 2 transactions in the last 5 or so years. It's just too convenient.

@Carlos-del-Amo-Montoya
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.

That depends.

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.

@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?

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
not personaly...

every single story i hear is prefaced with
"i know someone who"
