I was looking over my American Express benefits and found this at the bottom of the webpage: "A purchase may not earn additional points if the merchant submits the purchase using a mobile or wireless card reader or if you use a mobile or digital wallet." So if someone uses a Square reader and connects via cellular, you may not get your bonus points. Maybe you don't even get bonus points if the device to which the reader is connected is on Wifi. Apparently, if you use Apple Pay (regardless of the method of reader connection), you may not get your bonus points either. Might be worthwhile to review your card benefits with whatever other cards you've dumped into your eWallet on your iPhone6. Someone has to pay for this feature and it looks like it's going to be you.
