You clearly saw some value in the convenience. Smartphone and smartwatch NFC offers that convenience everywhere. Even setting up palm authentication feels like unnecessary work.
the Prime code thing is a good point tho
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.
A slice of cheese pizza is $2, and a bottle of water is $1. Then I sit in the park and watch life happen in front of me.
Very therapeutic.
Unlike your palmprint, you can get a new ring with a new private key if yours is compromised.
I thought that the engineering team at Amazon did a great job with Amazon One. I wish someone could pick up the tech and carry on.
Set up once with the CC with rewards for groceries, hover hand 2 seconds, done.
Apple Pay in the phone or watch are super convenient as well, but they take just a tad bit more of time between selecting the menus in the touch screen for pay options, and then selecting the matching CC.
I save like 30s? Possibly. Is this tech overkill? Most likely.
