So I finally went to SM today and used Samsung Pay. Let's just say it was not the best experience. The regulars weren't working so had to go to another lady. No problem I think. She rings me up for and I use SP for the purchase. Since the number on the receipt and the CC didn't match up she almost didn't make the sale. I had to show her that it masks the real CC and is actually more secure. I did have the actual card so I showed her that and she just kept going back and forth from the card to the receipt. Even called the manager (who knows me) and then decided to just let me continue with purchase. Got what I needed but not easy
. Will try with one of my regulars to see what they say but will ask first this time.
