Barcodes are machine readable symbols that store identifying data about the package or item with which they are associated. These symbols, when read by a barcode scanner, are decoded, recorded, and processed to extract the data for a variety of uses (e.g., pricing, order fulfillment, traceability through production, sortation, shipping, etc.)
Over the years, different forms of barcodes have been developed to help businesses around the world.
These include:
1-D linear barcodes
2-D matrix codes
Postal codes
Stacked linear barcodes
