> It points to Google's Android, which supports multiple wallets and does not collect a fee from card issuers for contactless payments. It suggests Apple would not be able to continue to charge "substantial fees" if it were forced to support other mobile wallets on Apple devices.
This described supporting multiple wallets, which I don’t care about. I don’t want multiple wallets, I want one wallet.
But anyway it sounds like the answer to my question is no, Apple is not doing anything meaningful per payment. They play a role in setting up a card and that's it. Is that accurate?
Apple doesn't see individual transactions when Apple Pay is used at retail stores' tap-to-pay terminals. The secret card payment token is sent from the phone to the credit-card's issuing bank and bypasses Apple servers. In this way, using Apple Pay is more secure and private than plastic cards because the real card number details remains hidden from the merchant.
The iPhone does contact Apple servers to add a new card to the digital wallet. Apple servers then contacts the issuing bank to get the secret token the bank generates and then puts it in the digital wallet. Conceivably, the "add a new card to digital wallet" could also have been done without Apple in the middle but it would require a much more convoluted, less secure, and more user-hostile workflow to do it. (e.g. the end user would have to know what bank endpoint to contact, manually enter the long and cryptic digits of the secret token, or maybe scan a QR code on a computer screen that's vulnerable to interception and phishing.)
BIN attacks [1] are still a thing. Your banks are probably just better at blocking them.

Swiping is where the risk is.
With tapping I could see how that is more secure but if they’re still providing the card details versus the secure token or something well… maybe it’s not?
Unless there’s a hidden magnetic reader in the chip-reading portion of the terminal, in which case the scammers could read like 1/3 of the magstripe data? Which doesn’t seem that useful tbh.
At least around where I am (Ohio, USA), at gas pumps and ATMs: Inserting the card for contact EMV typically means inserting the whole card.
In doing so, entire card is pushed all the way into the same slot that is also used for reading the magstripe, and to the same depth that is used for magstripe transactions.
This quality leaves the door open for magstripe skimming.
(It may be a stupid way of building things, but things exist in the real world that are built this way anyhow. Whether the information on the mag stripe still has any utility for a would-be thief in 2026 is a different matter.)
All three modern technologies ("original" Chip & PIN, wireless or a phone) are basically the EMV protocol, which is a fairly crap protocol which wasn't reviewed by experts before deployment - but is at least designed by people who have heard about cryptographic security and wanted to do that.
The original credit cards are just numbers written on a card. Clerk sees your number, memorizes it, now they can make arbitrary transactions indistinguishable from yours. Basically no security.
Magnetic stripe cards look more sophisticated but the stripe is basically the same numbers again but in a way humans cannot read. "Cloning" is just a matter of a machine copying those numbers onto another card's magnetic stripe. There's no real security improvement, though it is more convenient for the bank...
EMV ("Chip and PIN") is rather more complicated and could in principle be entirely secure - they could make it implausibly expensive to "clone" an EMV card, and require that you actually know your PIN for every transaction, so then crooks would need to learn your PIN and have the actual card, and that's a high bar.
In practice we didn't do much of that because it would be inconvenient, and so there are technical deficiencies, but realistically that XKCD "wrench" thing applies. Difficult technological attacks rarely happen, crooks threaten to stab you if you don't co-operate or they break into your home and steal your stuff, they do not come up with breakthrough cryptanalytic attacks on protocols. Mostly.
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 :)
So, are you sure you know what you are talking about?
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.)
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.
But it was too much work and didn't make the banks money so now we are also left to the American Visa parasite.
A protocol to support decentralized payments is a hobby project for an individual. You give each institution an identifier (e.g. their domain name) and each institution gives each customer an account number. If you're account 123 at Chase then you sign in as #123@chase.com, tell Chase you want to send $5 to #456@bankofamerica.com, they send the money and Bank of America tells their customer they have a new deposit. If you want to collect money from someone, you tell your bank to send their bank a payment request and they can either approve it manually (e.g. so you can deliver the goods for a one-time purchase) or configure some rules for which accounts get approved automatically up to some threshold amount (e.g. for recurring payments). Also no reason for banks in different countries not to all support the same protocol.
That doesn't require a central bank or any centralized third party payments intermediary. All it requires is for banks to know how to send money to other banks, which they obviously already do and the specific implementation of that isn't even relevant to the customer-facing payments protocol. So how does this not exist? It can't be that no one wants it, so it's got to be that someone (e.g. Visa/MasterCard) doesn't want it.
And there’s nothing preventing PoS from supporting individual wallet apps – see e.g. WeChat Pay / Alipay in China. (Alipay+ is also a “protocol”, i.e. other banks and wallets support it.)
