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.
Just ask the Clutter family. Oop, you can’t.
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.
