Radio Frequency Identification (RFID)
The Electronic Product Code™ (EPC) is syntax for unique identifiers assigned to physical objects, enabling automatic identification and tracking using RFID technology.
What is EPC/RFID?
EPCs have multiple representations, including binary forms suitable for use on Radio Frequency Identification (RFID) tags, and text forms suitable for data sharing among enterprise information systems.
Just as there are many types of barcodes, all RFID tags are not the same. Active and passive tags, NFC, UHF, HF, LF — they all work to meet the requirements of specific use cases. GS1 standards focus on UHF and HF passive RFID tags.
When unique EPCs are encoded onto individual RAIN RFID tags, radio waves can capture unique identifiers at extremely high rates and at distances well in excess of 10 metres, without line-of-sight contact.
Types of RFID tags
The most broadly implemented tags in our industries are UHF passive tags, also known as RAIN RFID tags.
UHF Passive (RAIN RFID)
Most broadly implemented. High read rates at distances over 10 metres. Ideal for supply chain visibility.
HF Passive
Shorter range, used for item-level tracking and NFC applications.
Active Tags
Battery-powered for longer range and additional sensor capabilities.
Benefits of RFID
Boost supply chain visibility and increase inventory accuracy.
Instant inventory counts
Count hundreds of items in seconds without line-of-sight scanning.
Real-time visibility
Know exactly where items are throughout your supply chain.
Reduced shrinkage
Better tracking means fewer lost or stolen items.
Improved customer experience
Ensure products are in stock and easy to locate.
GS1 EPC standards
GS1's EPC Tag Data Standard (TDS) specifies the data format of the EPC and provides encodings for numbering schemes — including the GS1 keys — within an EPC.
EPC Tag Data Standard (TDS)
Specifies the data format of the EPC and provides encodings for GS1 keys.
SGTIN
Serialised Global Trade Item Number for individual trade items.
SSCC
Serial Shipping Container Code for logistics units.
GRAI
Global Returnable Asset Identifier for reusable assets.
GIAI
Global Individual Asset Identifier for fixed assets.
Interoperability with barcodes
GS1 RFID standards use the same identification keys as barcodes (GTINs, GLNs, SSCCs). This means you can use a single identification system across both technologies, making it easier to implement and scale.
