A barcode is a set of black and white bars that represent a unique identification number for an item or product in logistics. Barcodes are used to automate the tracking and identification of items as they go through the supply chain. To read the barcode, a barcode scanner is employed, which subsequently sends the identifying number to a computer system where the item may be tracked and located.

Barcodes are frequently employed in logistics and supply chain management because they enable quick and accurate tracking of commodities as they move through the supply chain. This can include tracking things as they arrive at a warehouse, progress through the manufacturing process, are dispatched to merchants or customers, and are returned. Barcode tracking can also be used to check inventory levels, ensure shipment accuracy, and keep precise records of product movements.
