Digital Tag Basics for Animal Identification
What Is a Digital Tag?
A digital tag represents a modern solution for animal identification. It uses electronic technology to assign a unique identity to each animal. Unlike traditional visual methods such as brands, tattoos, or collars, digital tags rely on embedded electronic components. These components store and transmit identification data, making the process more reliable and efficient.
- Animal identification methods include both visual and electronic approaches.
- Electronic identification methods feature bar codes, two-dimensional symbology, RFID, and optical character recognition.
- RFID transponders can be embedded in ear tags, collars, injectable implants, or rumen boluses.
- Biometric identification methods exist but differ from RFID-based digital tags.
Digital tags for animal identification primarily use RFID technology. Passive RFID tags do not have an internal power source. They activate when scanned by a reader. Active RFID tags contain batteries, which allow for longer range but increase size and cost. These tags come in several physical forms, including ear tags, injectable subcutaneous transponders, and ruminal boluses. Each form suits specific animal types and management needs. For example, ear tags are easy to apply but may be lost or tampered with. Boluses are difficult to remove and less likely to be lost, but require careful administration and suit only certain animals. Injectable transponders combine the advantages of both but may migrate under the skin.
Technical standards for digital tags demand high reading efficiency, safety for both animals and humans, and no toxic residues in edible parts. Large-scale projects, such as the IDEA program in Europe, have validated the effectiveness and reliability of electronic identification systems across multiple livestock species.
