Thank you for the link. I have been able to add bank cards and credit cards for payment. But i was asking membership cards or loyalty cards. I have added to my phone samsung wallet but can't sync/see the option on my watch pro 5. Hence i wondered if its watch version related. Can you see it on your watch 6?
At the moment I'm using Google wallet and all my loyalty cards show up. I just scroll down and they show under my payment cards. I couldn't tell you with samsung wallet, I never set it up on my watch only my phone. Does need to be samsung wallet app.
I see I've not tried Google wallet as the samsung wallet on the phone and watch can be used as transport card and other promotions. Can you do that with Google wallet? Last I used it was 2 years ago.
Update: apparently Watch Pro 5 hardware/nfc doesn't support Samsung Wallet app which has loyalty cards. Watch Pro 5 uses Samsung Pay. Don't quite understand it, all I can sense as a consumer i need to upgrade to be able to use Samsung Wallet. Same fate as Google wallet, no membership cards on the watch. Oh well, life goes on.
