Link: NFCRing - Credit Card.
The forum describe that it is possible for some banks and credit cards, but does not describe the procedure for configure the ring.
Do you have a program or a manual to configure a ring with a credit card?
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.
