What is a Barcode and Why Use Our Generator?
Understanding Barcodes
A barcode is a machine-readable optical pattern consisting of parallel lines of varying widths and spaces. Originally invented in 1952, barcodes revolutionized product identification and tracking across industries. Today, they're essential for retail, logistics, healthcare, and manufacturing operations worldwide.
Each barcode format serves specific purposes: CODE128 for general text encoding, EAN13 for retail products, UPC for North American commerce, and specialized formats like Pharmacode for pharmaceutical applications.
How Barcodes Work
Data is encoded into a pattern of bars and spaces using specific algorithms
Laser or camera scanners read the pattern and decode the information
The decoded data triggers actions like inventory updates or price lookups
