It is the future. It is more secure, in that it doesn't really use my actually Credit Card number. It is nice to not have to reach for my wallet all the time. I don't think it will replace plastic cards, but I think it will become as widely used at some point. I used Android Pay for a while. I liked the idea of it being Android and NOT tied to Samsung's branding, I mean what if (God forbid) I want to own something besides a Galaxy some day? There where issue with Android Pay, it wasn't accepted very many places at all, and the few times I did get to use it like at McDonald and a few other places, it was SSSSSLLLLLLLLLOOOOOOOOOOWWWWWWW. I mean like 30 seconds to start processing, by that time people are looking at you like..... HURRY UP MAN, and PUT YOUR STUPID PHONE UP DORK! most unpleasant. With Samsung Pay, I've found this not to be the case. Rather paying at a NFC terminal or a regular card swipe terminal both where very fast. Some card swipe terms still required me to do the normal entering of my pin an what not. Basically the phone just transmitted the the card swipe info in place of swiping the card (pretty slick) but still served the purpose of not having to have a card with me at all.
