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]

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 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.

I've consciously reduced my pocket contents from car keys+wallet+phone to driver's license+phone. I'd love to be able to get rid of the phone sometimes.

Wear an NFC ring on your finger.

Unlike your palmprint, you can get a new ring with a new private key if yours is compromised.

A powered door lock and keypad and you won't even need the house key!

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.
