CNICK has partnered with Fidesmo, a payment service provider that works with a range of banks. Simply connect your supported payment cards to your ring and enjoy seamless payments wherever Visa and MasterCard are accepted. If your card is not on our supported list, you can get a Curve card (digital or physical) in just a few minutes. Once you have the Curve, you can link any Visa or MasterCard to it, and then connect the Curve card to your ring.
