I apologize if this is slightly off topic, but it does support the ease of use of Samsung Pay. I was in my local post office yesterday. I pulled out my phone to pay and the guy stops me with the usual, "we don't take that here". I said, ok, do you mind if I try anyway? He laughed and said, go right ahead. His jaw dropped when it worked. Then he wanted to know what phone I had and how I got that to work. He pulled out his iPhone 6s (I think that's what it was due to the headphone jack) and was like, "mine hardly ever works anywhere".
Since it was early in the morning and the post office was empty, I gave him the Samsung Pay 101 course which turned into an android v. iOS conversation. He was not a techy person. He couldn't believe some of the things I could do with my Note 8. Based on his reaction, he obviously had never seen a Note device. His friends and family had told him android phones were junk so he planned on just upgrading to the 8 or maybe the X. It was an interesting 5-10 minute conversation. I go into that post office at least once a week so I will be interested to see if he makes the jump from his iPhone.
