| sincere, non-trolling question: Why? 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. |

| 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 |

| ▲ | Eric_WVGG 6 hours ago | parent [-] | | 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 | | |

| ▲ | dangus 4 hours ago | parent | prev [-] | | Automatic loyalty cards are already supported in Apple Pay and I assume Google Pay as well. | | |
| ▲ | llsf 4 hours ago | parent [-] | | 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. |

| I like to go running with nothing on me besides a house key, and it's useful to be able to stop by Whole Foods after the run and buy a snack without a phone, watch, or wallet. |

| ▲ | reaperducer 2 hours ago | parent [-] | | Most of my lunch hours, I take nothing more than a five dollar bill. 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. |

| ▲ | llsf 4 hours ago | parent [-] | | It all boils down to the tradeoff between convenience and security.
I don't think it is particularly easy to replicate a living hand with all the blood vessels.
And it is not particularly easy to get a NFC ring with a secure element compatible with payment terminals. 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. | | |
| ▲ | octoberfranklin 2 hours ago | parent [-] | | Yeah 25 years ago people said stuff like that about fingerprint scanners, and then they got hacked by literal gummy bears: https://www.theregister.com/2002/05/16/gummi_bears_defeat_fi... 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. |

| Convenience? 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. |
