Something else I didn’t see in the comments so far is the NFC allows for unique transaction codes each time and thus doesn’t reveal any information. A static QR code could be “stolen” if it isn’t regenerated each time for security purposes.

Not sure how the system currently works but if the QR code is the same code every time that opens you up to someone just taking a picture of it and scanning it again later to charge you. I’d hope it’s unique each time cause otherwise that’s a huge step back

Seconding goodr. Decent polarization and sturdiness for a very reasonable cost. Do have some issues with scratching but when they cost less than dinner at a restaurant I don’t feel as bad about it.
