Arduino CueCat interface
This device saves the output from a barcode scanner onto an SD card, thus making the scanner portable, not requiring a computer. http://www.instructables.com/id/Make-a-portable-barcode-scanner-with-an-arduino-an/ Is the startup sound ridiculous? Yes, gloriously so. The camera I took this with does a terrible job of capturing sound, so the sound on this video is artificially spliced in. But those are the exact sound files it plays.
