Bar codes are used to uniquely identify a specific type of item in the store. This eases checkout because the price can be automatically looked up. It eases inventory because whenever an item is sold and leaves the store, the known quantity of stock decreases. This makes tracking supply, sales, and sales trends of specific items easier.
