another thing to add to my list of why qr codes suck irl: merchants have cracked screens
completely usable for human eye, not so much for qr
Discussion
Well it depends on the screen resolution and the QR information density.
Lightning QRs are unfortunate very dense, not ideal for merchants. But you can use QR translators.
i understand that part, my point is more that QRs as a format are not great for outside use cases, nfc is superior
still QR codes are simple and cheap. Ideal for online merchants. Also for donations - you can just print the QR with LNURL somewhere. No need for fancy NFC stack.
