This information comes from the card issuer directly, after the transaction has completed. It usually requires the mobile banking app to be installed.

The wallet app has a way to get the information, but it’s not from the tap itself. The tap interaction is not able to provide this information back to the phone (because the transaction auth happens long after the tap interaction completes).

Taps are designed to work with fully offline devices (which is why you can tap a plastic card, it is powered by the card terminal for the duration of the tap only, and requires no online interaction)

except of course it fucking doesn’t, I don’t have Chase or Amex apps on my phone… and yet my transactions are on my phone and watch and in a list inside my “wallet” and probably in the phone settings somewhere as well :)

Man, its amazing how confident you are about this, considering I know individual people who independently work at Visa, Mastercard, AND Apple, who have worked on mobile payments who independently confirm that none of them know any personal info and that its all pass-through.

So, are you sure you know what you are talking about?

This kind of appeal to authority [believe me because I say so!] doesn't really add much information, does it?

The report, above, is that previous transactions are visible within Apple's payment app. Apple agrees[1]. I'm willing to accept that this observation is based on reality and that it is reported in good faith.

Meanwhile, the suggestion is that Apple has no knowledge of transaction history.

Is there a way in which these two seemingly-conflicting concepts can be constructively combined into an understandable whole?

(For my part, I've never used Apple Pay and it's possible that I never will. I do not have a dog in this race.)

This is baffling, there's all sorts of information on my phone that Apple has zero knowledge of, why would the transactions be different?

Do you think Apple has complete copies of everything? I don't understand where this supposed contradiction is supposed to exist, unless you think that Apple has complete knowledge of all phone contents, which would require complete ignorance of the entire platform.

It's kind of unique. It involves finances, and reporting transactions, and it involves their app with their branding that runs on hardware that they unilaterally control. They apparently even take cut from the middle of each of these transaction.

If Apple does all of this with zero knowledge, then I am willing to accept accept that...

> Do you think Apple has complete copies of everything? I don't understand where this supposed contradiction is supposed to exist, unless you think that Apple has complete knowledge of all phone contents, which would require complete ignorance of the entire platform.

...but I'll only accept it if the functional operation can be explained.

This kind of non-explanatory browbeating doesn't further my understanding of anything at all. I have never endeavored to undertake a faith-based approach to understanding technology, and I'm certainly not going to begin doing so today.
