Bar codes are used by stores and supermarkets. Every product in the store would have a bar code, which would be scanned at the till or register to quickly access a database - which stores and retrieves the following data;
1. The Product Name
2. The Type of Product
3. The Price (not actually stored on the bar code, as this is always changing, but can be altered on the database).
Once scanned, the information will be added to the customers receipt. Some stores may also keep records of the bar codes scanned, so they can see what products sell well, and other details like that.
Barcodes are also used in industry. Steelmaking plants that make sheet steel first mill steel slabs out into a few kilometres of sheet - this is wound up into a 40-tonne coil for ease of handling. Each coil gets a barcode which can easily be read when coils are pulled from the warehouse for processing.
You'll also find barcodes on all kinds of electronic/computer equipment and (sometimes) on their individual components/subassemblies.
Barcodes give rapid and accurate identification of any coded item.
