What is a barcode?

Barcodes are graphic representations of numeric or alphanumeric data such as GTIN or GLN codes. Companies all over the world use them to unequivocally and automatically identify products, packages, pallets and locations.  

When scanned, they convey information about the associated product. They are extremely versatile symbols, capable of containing any type of information that may be required.

They play an important role in the supply chain of any industry, as they allow all parties involved to identify and track the movements of each product. The first use of barcodes in 1973 marked a breakthrough in product identification.
