Barcode Symbols

Barcodes are symbols that can be scanned electronically using laser or camera-based systems.

They are used to encode information such as product numbers, serial numbers and batch numbers. Barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain.
