Tracking is traditionally done with discount cards, and they are compatible with all payment methods. And there are applications that aggregate those discount cards in software: a discount card is just a short ID, nothing fancy.
Meanwhile, with my Samsung phone and its mag strip emulation, I can use my phone nearly everywhere anyway even if the store doesn't want to support NFC.
