I'm planning on opening a clothing store when I finish school, and I am wondering, how does using a cash register with all the bar codes and stuff work. Do I have to put them on file or something? Like the bar code with that item the article of clothing is?|||Duh. The computer doesn't know what the barcode means unless you tell it what you want.
It's a computer, remember? We built them which means we have to program them.
