I have called the bank and ask in person with Samsung store. When my card connects with my phone it unable to connect with my galaxy watch 6. It mentioned registration denied etc. I went to ask the bank and the samsung person to check, they said only 1 card per device which I found it dumb. I only have one card and I always use them now it can be used on my phone only not my watch due to one card one device can't used the same card into both devices.
Some banks indeed allow their card to be linked to two devices, but most bank only allow one card to one device. This is for security reason. Not Samsung fault but 100% bank control.
