A QR code is nothing more than an encoded string of text.
I would expect that if there was a "scan this QR code to pay" system, that the app you're using to pay would show you the amount about to be charged and that you would have to approve it.
I don't see anything wrong with it.

- dylan604 3y agooh joy, if we're now going to debate all of the uses of a qr code, then count me out. in fact, i'm pretty much done with your account altogether at this point.
- Sohcahtoa82 3y agoThere's nothing about QR codes that necessitates what you're talking about. Apple Pay and Google Pay could have easily worked using QR codes rather than NFC. The cash register would just need a QR code that was an encoded JSON payload that included the amount to be charged, a merchant name, and a merchant ID. You'd scan it using your chose payments app and the app would say something like "You're about to pay $13 to Bob's Burgers. Approve?" and you click Yes and you're done.
