I used to pay with Apple Pay for most purchases. Not sure why or how my mind was thinking of it as a better way to pay than handing my card or card info. I recently became aware of how horrible it is. It exposed my email, phone number, home address and sometimes physical location with some purchases.

I became aware of this when I made an online purchase and everything seemed fine except the order wasn't delivered. When I contacted customer service, they said they want to make sure the order was actually made by the card holder. They suspected fraud because I made the order with a different phone number than the one they had from Apple.
