If you're in the Southeast and use Regions Bank, know this — you're now supported by Samsung Pay. That means you can now add your puke green debit card or any of your Regions credit cards to Samsung Pay.
And, well, that's it. The big deal here is that, first, there are a ton of Samsung phones out there, with the GS7 and GS6 lines (and the Note 5) supporting Samsung Pay. The second is that Samsung Pay supports that newfangled MST thing wherein you can use your phone to pay anywhere you'd normally swipe a card — meaning that you can use it in far more places than you could Android Pay or Apple Pay. (On the other hand, that sometimes leads to interesting interactions.)
Thanks, @Jbkhd24, for the heads up!
