I was not under the impression that Apple Pay users have an imprint of their finger print next to the transaction information and time and date stamp somewhere. That would be ridiculous. If the user validates a transaction using their fingerprint, somewhere it probably say something along the lines of "verified with user's fingerprint, which is not stored here." This creates what we call, linkages. It's not all in one place. That would, again, be ridiculous. But, the more linkages you have the better picture you can draw.
