Our pal Matthew Panzarino at TechCrunch has some more of the nitpicky details on how the Apple Card works, including how exactly that magstripe on the physical card works when there’s no number printed:
The physical Apple Card, of course, has no number. The app displays the last 4 digits of the card number that is on the mag stripe of the card only, you never see the full card number.
The most interesting part of this is all the security that’s going into the system. By tying this so closely to Apple Pay, the company can backport some of the security and privacy advances it’s made there to using the card for non-online transactions as well. I’m sure there are a lot of folks who would be all too happy to have a credit card with better security, even if it’s not the best reward card or lowest-interest card around.
