What is a Barcode?
A barcode is a machine-readable representation of data that encodes information such as product numbers, serial numbers, or other identifiers. Barcodes are widely used in retail, logistics, inventory management, and industrial applications for efficient tracking and scanning.
How Barcodes Work
Barcodes represent data using a series of lines (bars) and spaces of varying widths or patterns. A barcode scanner reads these patterns using light sensors, converting them into digital information that a computer system can process. Common barcode standards include CODE128, EAN13, UPC, and CODE39.
Common Barcode Formats
| Format | Description | Usage |
|---|---|---|
| CODE128 | High-density alphanumeric | Shipping, logistics, and inventory |
| EAN13 | 13-digit numeric barcode | Retail products worldwide |
| UPC | 12-digit numeric barcode | Retail in North America |
| CODE39 | Alphanumeric with moderate density | Industrial and manufacturing use |
