I used it at Whole Foods cause it did my prime code and charged me at the same time without digging my phone out of my pocket but also my Whole Foods has bad reception so it’s annoying to use

You don't need reception of any kind to do an NFC payment, as long as the terminal has network access (even through ethernet).

the Prime code thing is a good point tho

I used Amazon One at my workplace all the time, but I only used it at the self-checkout line since I'd rarely get more than a few items, and the lines are shorter at this crowded neighborhood WF. There, I would scan all my items and use my palm to both log in to Prime and pay. Given that I would be scanning my own items, I much preferred it to phone or watch, as I didn't have to fish them out after scanning.

I am surprised nobody has mentioned the real joy of checkout at Whole Foods, which is that there is no annoying, incessant voice asking every self-checkout shopper, "Have you scanned your rewards card yet?" and "Please complete the transaction on the pin pad." It must be sheer torture working all day with those going off constantly.

Automatic loyalty cards are already supported in Apple Pay and I assume Google Pay as well.

In theory, but not in practice. The devil is in the details. Yes, Apple wallet and Google wallet allows to store loyalty cards. And those cards can be summoned using respectively VAS and SmartTap.

But... while all payment terminals are compatible to VAS and SmartTap, very few have the firmware and a POS that can make sense of it. So, in practice, beside Walgreens and maybe CSV, it is not much adopted.

Prime discounts were automatically applied if you use the credit card on your Amazon account I thought

The scanners were there before this.
