LCD Infrared bar code film

Place film between LCD screen and infrared bar code reader

Make a standard grocery store IR bar code reader work with a bar code on a LCD display. A film that could be put in between the scanner and the LCD display that would modify the laser's diffusion enough to make the technologies usable together.

       Could you provide a few more clues? Why is it currently not possible to hold a LCD-generated barcode up to the scanner? Is the pixelation a problem?

       I'm calling shenanigans. An infrared barcode reader?   

       There's nothing stopping a standard (laser-based) barcode reader from reading a barcode on a display.

       yahbut why ? if you've an LCD screen showing a barcode, then you have an electronic instrument that can be directly plugged in to the reader side.
