What Cow RFID Tags Do
Cow RFID tags give each animal a unique digital ID stored on an RFID chip inside a TPU ear tag. Farmers scan the tag with a handheld reader to pull up health records, breeding data, vaccination history, and movement logs — no printed numbers to squint at, no handwriting to decipher.
These tags use LF technology — you scan one animal at a time with a handheld stick reader, which is exactly what most farmers need at a chute or headgate. The chip stores a unique ID that links straight to your herd management records. See the specifications table below for exact frequency, chip options, and read range.
Why These Tags Stay On
- >300N tensile strength: Pull-tested to stay locked through rubbing, scratching, and daily movement — higher than many standard tags
- Stainless steel reinforcement: Anti-slip washer inside the locking mechanism reduces tag loss in active herds
- IP68 sealed body: Fully waterproof and dustproof — survives pressure washing, mud, and heavy rain without chip damage
- TPU injection-molded construction: Flexible, non-toxic, and skin-safe for multi-year wear on cattle of all ages
- Two chip options: EM4305 (FDX-B) or SIC7999 (HDX) — pick the chip that matches your reader setup
- Laser-etched marking: Numbers, farm names, or logos permanently burned into the surface — no ink to wear off
- Three color choices: Yellow, red, or pink — sort by group, age, or treatment status at a glance

Applications for Cattle Operations
- Individual identification: Scan each cow at the chute to record treatments, weights, and breeding data
- Herd health management: Link each tag to vaccination records, disease history, and treatment schedules
- Breeding programs: Track parentage, AI dates, calving intervals, and calf performance
- Feedlot tracking: Monitor weight gain, pen moves, and feed conversion for groups or individuals
- Movement and traceability: Document transfers between pastures, farms, markets, and processing facilities
- Regulatory compliance: Maintain traceable records that satisfy national livestock identification requirements
- Dairy operations: Connect each cow to milk yield, health treatments, and breeding cycles
How to Apply Cow RFID Tags
- Match the tag with the correct applicator for this tag model.
- Restrain the cow in a chute, headgate, or squeeze.
- Place the female tag on the inside of the ear and the male button on the outside.
- Squeeze the applicator firmly to lock the two parts together.
- Scan the tag with your LF reader and record the ID in your herd management system.

Frequently Asked Questions
Q: What are cow RFID tags?
A: Cow RFID tags are ear tags with an embedded RFID chip that stores a unique digital number. Farmers scan them with an LF reader to identify cattle and link each animal to health, breeding, and movement records.
Q: What frequency do these tags use?
A: These tags operate at 134.2 kHz LF under ISO 11785. This is the standard frequency for livestock identification worldwide and works with most handheld stick readers.
Q: What is the difference between EM4305 and SIC7999?
A: EM4305 uses FDX-B protocol with a read range of about 50 cm. SIC7999 uses HDX protocol with a read range of about 70 cm. Both comply with ISO 11785. Choose the chip that matches your existing reader infrastructure.
Q: How far can these tags be read?
A: EM4305 tags read up to 50 cm with a standard LF stick reader. SIC7999 tags read up to 70 cm. Actual distance depends on reader power and environmental conditions.
Q: Are these tags waterproof?
A: Yes. The TPU body is rated IP68 — fully sealed against water and dust. Tags survive rain, mud, and high-pressure washing without damaging the chip or fading the laser etching.
Q: Will the laser-etched numbers fade?
A: No. Laser etching burns the number into the TPU surface. It resists dirt, water, UV exposure, and abrasion better than printed or handwritten markings.
