My friend just sent this to me after seeing it at a Whole Foods in California:
With how easy it already is to tap a card, why would anybody sign up to use this for payment? It’s mind boggling to me.
Screw just your finger prints, Amazon already has access to that database thanks to the 5-0, so they now want to know every line on your hand! Best at least give people palm readings after the sign up! /s
I am fairly sure it just tokenizes the card number and it’s not to prevent tracking. Most retail stores have been only storing tokenized card numbers for a while now, Apple Pay or not. With Apple Pay, it would be for card skimmer protection. Regular cards would still be vulnerable at the scanner.
The payment processor, your bank and the store still know who made the purchase.
