Barcodes

Barcodes are symbols that can be scanned electronically using laser or camera-based systems.

They are used to encode information such as product numbers, serial numbers and batch numbers. Barcodes play a key role in supply chains, enabling parties like retailers, manufacturers, transport providers and hospitals to automatically identify and track products as they move through the supply chain.

GS1 manages several types of barcodes. Each is designed for use in a different situation.

RFID/EPC

The Electronic Product Code™ (EPC) is syntax for unique identifiers assigned to physical objects, unit loads, locations, or other identifiable entity playing a role in business operations.

When unique EPCs are encoded onto individual RFID tags, radio waves can be used to capture the unique identifiers at extremely high rates and at distances well in excess of 10 metres, without line-of-sight contact. These characteristics of RFID can be leveraged to boost supply chain visibility and increase inventory accuracy.
