Barcodes

A barcode is a pattern of lines and spaces that a scanner reads to identify a product. Each barcode is unique, so shops can track items and prices.

Barcodes make checkouts faster and help with stock control.

Each barcode represents a number that identifies a product. When a shop scanner reads the barcode, it looks up the number in a computer to find the price and name of the item.

Each product has its own unique barcode, so the shop can tell exactly which item has been sold and update its records automatically.
