Read QR code on boarding pass from phone with cracked screen

You should not rely on using of QR code on phone with cracked screen. If big part of your phone's screen is cracked, then there is a high probability that scanner will not be able to read a QR code.
QR code scanners often have problems with reading of QR codes from cracked phone screens. If there is only a small part of your screen cracked, you can try to enlarge the QR code and move it to the clear (non-cracked) part of screen. This solution may work, but if possible, you have to avoid using a phone with cracked screen when you need to scan a QR code from it.
The scanner will be most probably not able to read a QR code through the cracked screen. But it also depends a bit on the severity of the screen damage.
A cracked phone screen refracts (scatters) laser rays and the scanner is often unable to read a QR code.
