Yes it's constant. One # per card-device combo.
Of course it also sends a unique cryptogram alongside it with each transaction which is what makes it super secure. Even if the merchant is hacked, the device account # is useless to hackers. But it can be used to track your purchases.
- tzs 12y agoSo people trying to minimize tracking should not pay for their prescription drugs with Apple Pay, it sounds like. Only use it to purchase things that cannot inherently be tied to your identity. You can still be tracked from store to store, but they won't know who they tracking (until they start playing with face recognition, or putting a license plate scanner on the drive through, or things like that...).
- abalone 12y agoNo. First of all prescriptions are generally always logged under your name even if you pay cash. But more generally Apple Pay is no worse than paying by card, from a privacy standpoint.
