Barcodes make it easy to track the flow of goods from their point of origin to their final destination, to recall products that may pose a safety hazard, to detect counterfeit or fraudulent goods, and to link a product with information such as where it was made, where it has been, ingredient lists, and instruction manuals in multiple languages. The global immunization community has recently started to explore the potential of using barcodes in vaccine supply chains. In fact, some countries have already begun to establish and mandate their own barcode standards.
