If your payment card can be connected or not depends on your bank. If your bank has activated Fidesmo Pay, then your payment card can be connected. Go to Fidesmo Pay to see the supported payment cards.
If none of your cards are supported by Fidesmo Pay, an alternative is CURVE, with it you can connect your payment card to your CURVE card and that CURVE card can be connected to your wearable without any issue. You can get CURVE here.
