Where does it say BMO cards are supported on Samsung pay? only BMO Harris supports Samsung Pay. Which is BMO in the U.S. I have a BMO Harris debit mastercard from the U.S. and it works. However Canadian BMO consumer cards are not supported on Samsung pay and I don't think that will be changing soon. I can't upload my BMO debit interact card neither my BMO mastercard. BMO however does support Google Pay in Canada. Which is a different app.
