Understanding Barcodes

Barcodes are machine-readable representations of data in visual format, typically consisting of parallel lines (bars) of varying widths. They're essential for inventory management, point-of-sale systems, shipping logistics, and product identification. Modern barcode technology enables fast, accurate data capture and has revolutionized retail, warehousing, and supply chain management worldwide.
