Is that right? My understanding is the physical AppleCard has a fixed number that is simply not printed and relies on rotating CVV via the standard chip reading like most standard chip cards. The device-based ApplePay can rotate its number but that too only rotates CVV by default.
My point was only that the card-chip associated number, the ApplePay associated number, and the number the user hands out to web sites, are not correlated. The user could choose to change their CC number every day when they wake up if they want, and the physical card does not change in any way as a result. Nor does it need to, since you cannot use it outside of the card.
