Most CC companies are releasing cards with near field chips that do the same thing. You cant get mad at WalMart. Thats not their call; the POS vendor is the one dictating that.
So far, Walmart is the ONLY location that does NOT accept Samsung Pay. This started a couple of weeks ago.
I use the SAME credit card on my Samsung Pay for almost all my transactions and it has been working fine EVERYWHERE until Walmart alone started blocking it recently.
Walmart dictates to their POS vendor, not the other way around.
But Samsung Pay? Really?
