Here's another video for you. They scan a temporary barcode tattoo with a barcode scanner. I think it's kinda funny. And just in case you don't know...RTFM means Read The F*$%ing Manual. So not only is it funny that it actually scans, but it's also funny that it pretty tells you that you're an idiot for scanning it in the first place. I wonder if the software would work with actual tattoos too.
