Hi everyone. I've used Samsung Pay everywhere with mixed results and have finally reached an ideal user method that allows it to work 99% of the time.
I realized the relay mechanism inside the phone is in the upper (2/3 up) center within the phone and that most magnetic strip readers have theirs in the lower 2/3 part of their receiver. Both must be in close proximity. If you keep moving it, this does not help.
Essentially I place my upper (not top) area of my phone on the lower (not bottom) part of the strip reader. This has prove success every time. GOOD LUCK EVERYONE!!!
