> You don't have to line up the codes with the phones

A good QR reader does not require much lining up, just pointing the phone in the general direction of the code is sufficient, I'm consistently surprised by how fast some QR readers match codes.

That's significantly less work than having to bring your phone right next to a reader.

Every time my friend and I went to costas, I would check out much faster than him with a basic unionpay debit card while he was using alipay and it took time for the baristas to setup their equipment then to do the scan.
