Samsung calls it "Magnetic Secure Transmission" as I recall. I wish they would advertise it more because it was honestly the greatest feature on that phone in my eyes, but everyone assumes it's exactly the same as Apple Pay. Retailers were shocked every time I used it (though in some cases they refused to even let me try).

I'm personally glad to be off Samsung products again now, but I was really disappointed when my spouse switched to a model without MST.
