Do you understand bar-coding

Does anyone understand how bar coding works. I am just trying to understand how they work.

At the supermarket, the barcode is telling the store inventory system that the product you are buying has reached the checkout stand and is being transferred out of inventory. In a sense, the barcode is a tool for tracking the location of something, whether it is a can of soup, or a freight car.
