Working great. Every time I try and use it the clerk always wants to tell me they don't accept Apple Pay. I say, humor an older guy and let me try something. Put the phone against the reader and it works fine. What is especially nice, is not only does it give you an acknowledgement of the transaction immediately to the phone, but if you tap on the notification, it will show you the last few Amex charges you have had. In fact, any time someone runs your Amex card outside of Samsung Pay, such as at a gas station or restaurant, you still get the notification of the charge being processed. So I guess that might be an Amex thing rather than a Samsung Pay thing. In any case Thumbs up on this App and when it works at the gas pump it will be great.
