Aren't cellphone NFC payment essentially a long-form version of this? As far as the machine is concerned they're getting your CC info, but Google/Samsung/Apple Pay are acting as a middleman and your actual credit card information is never actually shared.
Yeah, it has it's perks but my NFC stops working on a regular basis. Also I don't like having my payments go through a spyware conglomerate.
As far as I know, modern cards don't just send your CC info to terminals, they do some form of a cryptographic handshake (probably a pubkey signature or similar) which gets confirmed by your bank. I believe Caveman was talking more about online shopping, where you have to enter your card number, expiration date, CVC and often your name too.
I've run across a few sites that allow me to check out entirely through Google Pay or PayPal, but not many. I still don't love the info going through Google, but at this point they already have all my information, so it doesn't really make much of a difference at this point.
And of course for anything that needs to be shipped they are going to need a name and shipping address.
I would like to seeegally mandatory "guest checkout" options with protections on data use. They'll need to keep some kind of invoice/receipt of the transaction, but it should be illegal to use it for any other purposes than order/purchase tracking for guest accounts.
