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. |

(you might be testing either barcode generating software or a barcode reader) |
