I found out about it by accident two days ago when on a whim I tried to add it and it accepted it and needed to verify with the Capital One wallet. I don't use that CC a lot so it wasn't a big deal, but it now works with everything I have... It also works with Chase and Citi debit cards, too. I use it mostly with my AmEx. Samsung Pay has really gone to the next level and have blown past Android Pay, IMHO.
