Barcodes are the most popular data carriers—it is one of the most frequently used methods of goods automatic identification.
GS1, managing barcode systems, is an international non-profit organization that creates and implements open identification and communication standards in supply chains in the whole world, regardless of the industry, based on barcodes and RFID systems.
With unique identification of products, transport packages, resources, localizations, and services, GS1 standards facilitate effective management of global supply chains including many industries. The most important standards include: global identification of trade items (Global Trade Item Number – GTIN), global location identification (Global Location Number – GLN), and global identification of logistic units (SSCC numbers). What is more, barcodes are used for resource identification, determining location, and in many other aspects of life (marking tickets, documents, packages, books, medical samples, etc.).
