What is a Barcode?
Machine-readable data encoding for retail, inventory, and logistics
A barcode is a visual pattern of parallel lines and spaces that represents data in a machine-readable format. When scanned by a laser or optical sensor, barcodes quickly retrieve associated product names, prices, SKU numbers, or tracking records. Using barcodes eliminates manual typing errors, dramatically accelerates checkout times, and simplifies inventory management.
