ISO 11784:1996/Amd 1:2004

Overview

ISO 11784:1996/Amd 1:2004 is an important amendment to the international standard governing radio frequency identification (RFID) of animals, focusing specifically on the code structure used in RFID transponders. Published by the International Organization for Standardization (ISO), this amendment enhances the original 1996 standard by introducing new provisions for managing country codes, retagging processes, and user-specific information fields. The amendment supports consistent and reliable animal identification worldwide, facilitating improved tracking and management in agriculture, veterinary practice, and wildlife monitoring.

Key Topics

Country Code Alignment

• The amendment mandates that bits 17 to 26 of the transponder’s code must contain a valid numeric-3 country code as defined by the ISO 3166 standard.
• This ensures harmonized geographic identification aligned with an internationally recognized country-coding scheme, enhancing interoperability.

Retagging Process

• Introduces definitions and specifications for retagging - assigning a new transponder to an animal while maintaining the original identification number if the first tag is lost or unreadable.
• A three-bit retagging counter is implemented to track the number of times an animal has been retagged, helping maintain data integrity.

User Information Field

• A new five-bit user information field allows additional user-specific data to be embedded in the transponder.
• This field is country-specific and used alongside the country code, enabling customization and extended data storage.

Code Structure Adjustments

• The standard revises portions of the code structure by splitting the previously reserved bits into three distinct segments: the retagging counter (bits 2-4), user information field (bits 5-9), and reserved bits (bits 10-15 which must be zero).
• Ensures clarity and expands the capability of transponders within the existing identification framework.

Applications

ISO 11784:1996/Amd 1:2004 serves as a critical framework for a variety of animal identification solutions utilizing RFID technology, including:

• Livestock Management: Enables reliable individual animal identification for breeding, health monitoring, and traceability.
• Wildlife Conservation: Supports tracking and monitoring of endangered species and game animals.
• Veterinary Practices: Enhances animal health records by ensuring unique and persistent identification codes.
• Regulatory Compliance: Assists in meeting legal and sanitary requirements related to animal movement and identification.
• Agricultural Technology Development: Provides standards for manufacturers and developers producing RFID tags and readers compatible worldwide.

Related Standards

• ISO 3166: Defines the numeric country codes referenced in this amendment to ensure global consistency.
• ISO 11785: Specifies the technical communication protocols for RFID transponders in animals, complementing ISO 11784’s code structure.
• Additional standards on animal health and traceability may interact with ISO 11784 in regulatory or technological ecosystems.

By adopting ISO 11784:1996/Amd 1:2004, stakeholders in animal identification benefit from greater accuracy, interoperability, and traceability, supporting efficient farm management, animal welfare, and global trade compliance through advanced RFID technology.
