Overview
ISO 14223-3:2018 - "Radiofrequency identification of animals - Advanced transponders - Part 3: Applications" specifies how additional data is organized, formatted and accessed inside advanced animal RFID transponders. It defines a mandatory fixed memory part (ISO 11785 data field and the Data_Config field) and an optional user memory part (fixed allocation fields and Object Identifier (OID)-separated data) to provide flexible, future‑proof storage for animal-related information.
Key topics and technical requirements
- Memory partitioning
- Fixed part (mandatory): ISO 11785 AID plus Data_Config (Block #4) describing transponder configuration.
- User part (optional): fixed allocation and OID-based separation for flexible fields.
- Access modes
- Single Access Memory (SAM) mode for predefined, fast-access fields.
- Data Dictionary Memory (DDM) mode for OID-defined, variable-length fields.
- Data structure and configuration
- Data_Config field is required and encoded to indicate features (e.g., presence of DDM, sensor block, user blocks).
- DFID (Data Format Identifier) codes define fixed data layouts; DFID assignment is controlled by ISO TC 23/SC 19.
- DSFID (Data Storage Format Identifier) indicates page-based (Page ≥ 1) access modes.
- Compatibility and flags
- Backwards compatibility with ISO 11784/11785 is maintained. Bit15 of the ISO 11784 frame denotes an advanced transponder (set to 1); Bit16 indicates additional data in trailer bits (set to 1).
- Sensor and TLV concepts
- A dedicated sensor data field is defined (single-block on Page 0 DFID); additional sensor blocks use DSFID/page-based formats, proprietary formats, or new DFID codes.
- Type-Length-Value (TLV) mechanisms are used for variable-length fields in the DDM.
Applications and users
ISO 14223-3 is aimed at implementers and stakeholders who need standardized, extensible animal identification data in RFID transponders:
- RFID manufacturers designing advanced transponders and readers
- Software/system integrators building animal traceability, herd management, or supply‑chain systems
- Veterinary and animal health authorities for vaccination, disease surveillance, and regulatory traceability
- Livestock producers and breeders needing embedded records (health, breeding, sensor telemetry)
- Food supply chain and traceability platforms requiring persistent, standardized animal IDs and supplementary data
Practical uses include embedding health records, vaccination status, sensor measurements, breeding history, or supply‑chain metadata directly on the animal transponder while preserving interoperability with legacy ISO 11784/11785 readers.
