The Apple Pay numbers differ—each device gets a unique number—but are you sure the card number is different? There is a place in the app where you can see your full card number and CVV in case you need to do a transaction over the phone. I thought that was the physical card number, but it could be yet another number—not Apple Pay and not the physical card.
I didn’t think every transaction got its own number. There was some reporting to that effect early on, but Apple Pay seems to generate a fixed number by device, and you can view the last 4 digits in the Wallet. Maybe they’re doing something in addition, though. I’m not an electronic payments expert by any stretch. Sorry to drag this off topic!
