Amex American Express gold cards.
This is not a question but a tip. If you are having trouble adding an Amex gold card , like a Sky Miles Card, etc. to Apple Pay because it won’t accept a 3 digit CCV, which is on the back of the card. Look at the front of your card again. On the right hand edge of the card, right beside the tap to pay symbol (looks like waves) that is the security code it wants. I have trouble seeing and I totally missed it at first! I hope this helps you and that you have a wonderful day!
