They can DO that?

I wouldn't think a laser scanner would be able to read the screen of a phone.

The Fandango people were talking about doing something like that for their ticketing app on the phone, which, if it works, would be just fantastic. I just didn't think it could be done.


Laser scanners can't, but they are for 1D barcodes only. The 2D "scanners" are actually an LED floodlight and a 2D CCD imager plus software that looks for and interprets the 2D barcode. This should work on almost anything, even if the screen is non-reflective like an OLED.
