The HITAG series is a family of low-frequency (LF) RFID transponder chips widely used in livestock identification, animal tracking, and industrial logistics. Developed originally for high-reliability environments, HITAG chips are known for stable read performance, strong anti-interference capability, and compliance with international animal identification standards.
What Is the HITAG RFID Series?
HITAG is a passive LF RFID technology operating at 125 kHz, designed primarily for:
- Livestock and animal identification
- Agricultural traceability systems
- Secure industrial identification
- Logistics tracking in harsh environments
Most HITAG chips are fully compatible with ISO 11784/85 and ISO 14223, the globally accepted standards for animal identification.
HITAG Series Comparison Overview
The table below summarizes the key technical differences across HITAG products:
| Product | Total Memory (bits) | RF Interface | Anti-Collision | Unique ID | R/W Lock | Security | Write Command | Typical Applications |
|---|---|---|---|---|---|---|---|---|
| HITAG µ / Advanced / Advanced+ | 512 – 1760 | ISO 11784/85 ISO 14223 |
Up to 60 tags/sec | 48-bit | Yes | Yes | Supported | Livestock Management |
| HITAG S | 256 – 2048 | ISO 11784/85 | – | 48-bit | – | – | – | Livestock Management |
| HITAG 2 | 256 | HITAG 2 ISO 11784/85 |
– | 32-bit | – | – | – | Livestock Management |
| HITAG 1 | 2048 | HITAG 1 | Up to 15 tags/sec | 32-bit | – | – | – | Logistics Tracking |
HITAG µ / Advanced / Advanced+
HITAG Advanced and Advanced+ are the most powerful members of the HITAG family.
Key Advantages
- High anti-collision performance (up to 60 tags per second)
- Larger memory capacity (up to 1760 bits)
- Integrated security mechanisms
- Read/write lock capability
- Full support for ISO 11784/85 and ISO 14223
Best Use Cases
- National livestock identification systems
- Large-scale cattle, sheep, and pig farms
- Government-regulated animal traceability projects
These chips are commonly embedded in animal ear tags, injectable microchips, and RFID boluses.
HITAG S: Flexible Memory for Livestock Identification
HITAG S offers a wider memory range (256–2048 bits), making it suitable for projects that require customized data structures.

How to Choose the Right HITAG Chip
When selecting a HITAG RFID solution, consider:
- Regulatory requirements (ISO 11784/85 compliance)
- Memory needs (basic ID vs. extended data storage)
- Reading speed & anti-collision performance
- Security and write protection
- Application environment (animal body, outdoor, industrial)
Conclusion
The HITAG RFID series remains a cornerstone technology for livestock management and industrial identification. From high-performance HITAG Advanced+ to cost-effective HITAG 2, each variant serves a clear purpose.
By understanding their differences, system integrators and buyers can build reliable, standards-compliant RFID solutions with long-term scalability.
