QR codes in my opinion are more efficient. NFC requires the devices almost touch each other, QR codes work from a distance.
That may be. I'm not saying to abandon one for the other. It just seems silly that a cracked screen should be an impediment when phones' core function is to send data between each other non-visually.

That made me think... cracked screen is a quite common thing. People use their phones with cracked screens. Maybe this is an actual issue.

It didn't occur to me, before reading this post, but I definitely know people who use phones with cracked screens.

Yea, it could be the opposite problem as well where the camera isn't reading the QR code for whatever reason. Both LCD and Camera issues. I think most wallets should have the option for NFC if QR functionality fails.

Once upon a time it seemed silly to me that people will actually use the screen to type and not physical buttons. To me it is still extremely inconvenient to this day (fat fingers). Nevertheless, the touch screen is so versatile that its versatility trumps this (to me major) inconvenience. In the same way the camera has became a versatile input device. It is used not only for its originally intended purpose (taking pictures), but also to transfer information.
As for the NFC... there are actually wallets that support NFC. Zeus supports it (I haven't tested it but I would guess it works).
