Half Duplex Electronic Ear Tag: Reliable Signal Performance in Metal Environments
The HDX ear tag is a durable, high-quality HDX half duplex electronic ear tag for livestock identification for pigs, cattle, sheep, goats, deer and camels. With the help of RFID electronic identification system, animals can be automatically identified and animal information can be automatically collected and recorded.
Unlike Full Duplex alternatives, the Half Duplex technology uses sequential signal transmission-the reader sends a pulse to charge the tag's capacitor, then receives data without interference. This design provides better noise immunity for consistent readings near steel chutes, metal headgates, and industrial farm equipment where standard FDX tags may struggle.
- Each tag contains a unique 15-digit identification number
- EM4305 chip with read/write capability for flexible data management
- ISO 11784/11785 compliance for universal reader compatibility
- TPU construction resistant to UV and extreme temperatures

HDX vs. FDX Selection Guide: HDX (Half Duplex) ear tags are better suited for operations with older metal cattle crushes, steel squeeze chutes, or environments with significant electromagnetic interference. The Half Duplex protocol provides better noise immunity than FDX. FDX tags are a more economical option when metal interference is not a concern. For a deeper technical breakdown, see our full comparison of FDX-B and HDX ear tag protocols.
Why Choose Our HDX Livestock Ear Tags
Engineered for reliable performance in demanding agricultural traceability systems
Metal-Environment Optimized Performance
Half Duplex signal transmission eliminates reader interference during data capture. The HDX protocol's sequential charging and response cycle ensures consistent identification even adjacent to steel headgates, metal chutes, and galvanized fencing-environments where FDX tags commonly produce unreliable reads.
Extended Scanning Distance
HDX tags typically offer longer read distances compared to standard FDX alternatives. This enhanced detection capability allows more efficient cattle processing during weighing, vaccination, and sorting operations-reducing handler stress while maintaining accurate electronic herd records.
ISO-Certified Traceability Compliance
Full ISO 11784/11785 protocol support enables seamless integration with universal readers and national livestock databases. Each electronic ear tag contains a globally unique identification code compatible with disease outbreak tracking, export certification, and governmental animal health programs.
Durable TPU Construction
Our TPU-encapsulated ear tag withstands continuous exposure to manure, agricultural chemicals, and UV radiation. The environmentally friendly material is designed for long-term field use, with compact and lightweight design that does not interfere with the animal's activities.
Flexible Data Encoding Options
The EM4305 chip provides read/write capability for customized identification schemes. Program ICAR codes, national herd numbers, or proprietary farm management data. Support for both HDX and FDX-B protocols enables compatibility with various reader infrastructure.
Factory-Direct Pricing Advantage
As a manufacturer with our own TPU producing machine since 2006, we offer competitive pricing on electronic ear tag orders. OEM customization available-private labeling, custom colors, pre-loaded data encoding, and multilingual packaging for agricultural distributors worldwide.

Frequently Asked Questions
Q: What is the difference between HDX and FDX ear tags?
A: HDX (Half Duplex) ear tags use sequential signal transmission where the reader sends a pulse first, then the tag responds. This makes HDX tags better suited for environments with metal interference such as older cattle crushes and steel chutes. FDX (Full Duplex) tags communicate simultaneously with the reader and are more economical, suitable for standard farm environments. Both follow ISO 11784/11785 standards and can be read by the same ISO-compliant readers.
Q: Are these HDX ear tags compatible with existing ISO readers?
A: Yes. Our electronic ear tags comply fully with ISO 11784 (code structure) and ISO 11785 (technical concept) standards. They are readable by any ISO-compliant animal identification reader, including handheld wand scanners, panel antenna systems, and integrated race/chute readers from various manufacturers.
Q: Can the EM4305 chip store custom data?
A: Yes. The EM4305 chip provides read/write capability, allowing storage of the standard ISO animal code plus additional user data. This enables encoding of ICAR codes, national herd numbers, or proprietary farm management identifiers. We offer pre-programming services for bulk orders.
Q: How long does the data last in the ear tag?
A: The passive RFID transponder requires no battery and maintains data retention for 20+ years. The TPU material is UV-resistant, chemical-resistant, and tested for temperature extremes from -25°C to +70°C. The compact design does not interfere with animal activities while ensuring long-term durability.
Q: How do I properly install the HDX ear tag?
A: Use a cattle ear tag applicator tool to fix the ear tag on the animal's ear. Position the tag in the middle third of the ear, between the two cartilage ribs, avoiding major blood vessels. Make sure the ear tag number or chip is not blocked. Scan and test after installation to confirm data can be read normally.
