What is GS1 Standards
GS1 standards create a common foundation for business by uniquely identifying, accurately capturing and automatically sharing vital information about products, locations, assets and more. Our standards make it possible for companies to speak the common language and enable visibility in the supply chain.
Globally unique identification(ID)keys for identifying trade items, logistic units, locations and assets across the supply chain from manufacturer to consumer. GS1 ID Keys enable organisations to assign standard identifiers to products, documents, physical locations and more.

Automatic data capture from data carriers like barcodes and RFID, which allow GS1 ID keys and supplementary data to be understood.
GS1 Data Carrier - Barcodes
A barcode represents numbers or letters in a machine-readable format that can be decoded, recorded and processed by a computer system when read by a barcode scanner. Know More
GS1 Data Carrier -EPC-enabled RFID Tags
The Electronic Product Code (EPC) is syntax for unique identifiers assigned to physical objects, locations or other identifiable entity playing a role in business operations.
When unique EPCs are encoded on to individual Radio Frequency Identification (RFID)tags, radio waves can be used to capture the unique identifiers at extremely high rates and at distances without line-of-sight contact, which can be leveraged to boost supply chain visibility and increase inventory accuracy.
When to use RFID:
- Inventory management: Counting and identifying multiple objects simultaneously and quickly to increase inventory accuracy
- Unmanned store: Automatically identifying products to increase labour productivity
