Physical Protections
It’s worth noting that the physical Apple Card doesn’t sport some of these privacy-protecting features. It still technically has a physical card number (though you won’t be able to see it) and it’s vulnerable to data skimming attacks like any other magnetic strip-based credit card. (If you’re worried about the latter, invest in an RFID-blocking sleeve.)
But the Apple Card does do privacy and security well for a physical credit card. There are no numbers on the actual face of the card and the card number itself doesn’t appear to be attached to any of the temporary numbers you use online or via Apple Pay. It doesn’t prevent you from leaving a digital footprint, but it could help confuse data miners.
