Answer 1

Barcodes are registered with the GS1, a not-for-profit organization that manages the global supply chain. Barcodes are assigned to products by manufacturers who then print the barcodes on product packaging. When a product is scanned at a store, the barcode is read and the product information is looked up in a database.
