I used them in whole foods all the time
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
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.
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.
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.

For 2020's-era palm scanners you don't have to replicate a 3D hand -- just like a video chat doesn't replicate my 3D face. You just have to emit photons (some of them infrared, yes) in the correct pattern. The hack won't look like a 3D-printed hand, it'll look like a display panel that works beyond visible wavelengths. It'll probably be some device developed for a totally unrelated market, and then one day "whoops, all those palm scanners are 0wn3d" (natürlich auf Deutsch) will be a talk title at CCC.
But all this is academic. The real problem with biometrics is that when your password is a body part, you can't change your password.
If someone manages to replicate my pulsing blood vessels from my hand and trick the scanner, that would be fine. I would dispute the purchase, and the store would not even pull the camera footage, and just refund.
Amazon Go was not used to hold access to bank accounts or crypto wallets. I think it was a good technology and balance between convenience and security, for the purpose (grocery loyalty and payment).
A twin or even sometimes a relative (son and mother) can open an iphone and its banking apps using the facial recognition. That is more concerning to me than Amazon Go palm scanning for groceries.
This is not even remotely true. Credit card chips do real cryptography.
It's been a decade since I saw a card terminal without a chip reader, except for parking meters and soft drink vending machines.
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.
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.
