99% of barcode scanners are a laser that can't read LCD screens which makes apps such as this pretty much useless.
Are the AirNZ scanners not laser? I'm thinking the check-in kiosks and the gate scanners. And I always scan my phone at the movies too? Or am I just linking a red light with lasers?
Some modules are both LED 2D Imaging + laser. Others are one or the other. Lotto use similar, 2 lenses that cross reference the image with LEDs lit from the edges
