alt Hacker News>Apple Pay does not, runs the whole thing on-device
so when I use the physical card that is also on Apple Pay, and Apple Pay tells me I just made a transaction as if I had used Apple Pay, that is all happening on my device? what online service is my phone using to track my account with Visa or my credit card issuer, and it's polling or push?
You get a notification from Apple Pay when you pay with your physical card? Because I only get a notification from my bank's app whenever I use my physical card. Apple Pay notifications only pop up when using Apple Pay itself.
