What is barcode?
A barcode is a machine-readable pattern that stores information, usually about a product, item, or identifier. A barcode scanner reads the pattern and converts it into digital data that may be number or text.
A traditional barcode uses lines and spaces of different widths to represent data. A scanner detects the pattern and converts it into information that a computer system can understand.
For example:
Product -> Barcode -> Scanner -> Product ID -> Database
The barcode itself usually doesn't contain all the product details. Instead, it often contains an identifier, such as a product number. The store's database then uses that number to find the product name, price, stock information, etc.
