I am not a user of Samsung Pay, since I have an iPhone. But I do use Apple Pay whenever I get the chance. It's basically the same NFC technology in the end, and most places that I see the NFC wireless logo, I have not had a problem paying with Apple Pay even if it doesn't explicitly have the Apple Pay logo on it. From my perspective, the biggest obstacle to the acceptance of NFC-based payments is getting the retailers to adopt it. The banks are on board, because if the increased security, and many early adopters seem to like it's ease of use. Most of the time, when I go to an establishment and pay with my phone, I get the, "Wow! That's cool!" So people do seem to like the technology. However, the problem is that the store clerks accepting payments should not be reacting to the technology this way when people pay using their phones. Just last week, I was at a restaurant in Frankfort, Kentucky, and paid using Apple Pay, and the server as totally shocked and surprised that someone could pay with their phone! Seriously, it's your POS checkout system. You should be familiar with all forms of payment that are accepted. Why is NFC being adopted on various POS devices yet there is no training of the front-end clerks as to the fact that NFC-based payments are being accepted?
