What is a barcode?

A barcode is a pattern made up of black bars and spaces to represent numerical or textual information. It can be quickly read by a barcode scanner, converting the pattern into data that computers can recognize. It is commonly used in supermarkets, courier services, and other scenarios to label products or packages.

The working principle of a barcode is simple: the scanner shines light on the barcode, and the way different bars and spaces reflect the light forms data. There are two main types of barcodes: one-dimensional barcodes, which resemble striped patterns and are commonly used to represent numbers; and two-dimensional barcodes, like the commonly seen QR code, which can store more complex information.

Barcodes are widely used in daily life and work, such as product price tags, express delivery tracking numbers, ticket scanning, etc. They make information processing faster and more accurate, reducing manual input errors, and are indispensable little tools in modern life.
