How RFID Cow Tags Work
RFID cow tags store a unique digital number on a UCODE 8 chip sealed inside a TPU ear tag. When a UHF reader sends a signal at 860–960 MHz, the tag sends back its ID — no line of sight needed, no printed numbers to squint at. Farmers scan cattle at gates, in chutes, or in races, and the ID links straight to health records, breeding data, and movement logs.
Because these tags use UHF, you get read ranges up to 4 meters with a fixed reader. That means you can scan cattle as they walk through a race or past a gate without stopping each animal. The UCODE 8 chip is designed for fast, reliable reads even when multiple tags are in range — so scanning a pen of calves at once is no problem.
What Makes These Tags Different
- Long-range UHF reading: UCODE 8 chip reads up to 4 meters — scan cattle as they pass through races or gates without stopping each animal
- Personalized laser etching: Sequential numbers, custom ranges, farm names, or logos — permanently marked, no fading
- Color coding for herd sorting: Yellow, blue, or orange to separate breeding groups, treatment batches, or age classes at a glance
- IP68 sealed body: Withstands mud, rain, and high-pressure washing without compromising the chip
- TPU construction: Flexible, non-toxic, and skin-safe for multi-year wear on cattle and calves
- Secure button lock: Male and female halves lock tight — no tag loss from rubbing, scratching, or ear pulling

Applications for Cattle and Calf Operations
- Calf rearing: Tag calves at birth to track weight, parentage, and weaning dates from day one
- Dairy herd management: Link each cow to milk yield, health treatments, and breeding cycles
- Feedlot tracking: Monitor weight gain, pen moves, and feed conversion for groups or individuals
- Health and vaccination programs: Scan to record treatments, prevent double-dosing, and flag sick animals
- Breeding records: Track parentage, AI dates, and calving intervals with unique IDs
- Movement and traceability: Record transfers between pastures, farms, markets, and slaughter facilities
- Regulatory compliance: Maintain traceable records that satisfy national livestock identification programs
How to Apply RFID Tags for Cows
- Match the tag with the correct applicator for your tag model.
- Restrain the cow or calf in a chute, headgate, or calf cradle.
- 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 reader and record the ID in your herd management system.

Frequently Asked Questions
Q: What are RFID cow tags?
A: RFID cow tags are ear tags with an embedded chip that stores a unique digital number. Farmers scan them with an RFID reader to identify cattle without reading printed numbers by hand.
Q: What frequency do these tags use?
A: These tags operate at 860–960 MHz UHF using the UCODE 8 chip, compliant with ISO 18000-6C. Read range reaches up to 4 meters with a fixed reader.
Q: Can I personalize these tags?
A: Yes. Each tag can be laser-etched with sequential numbers, custom text, farm names, or logos. Color options include yellow, blue, and orange.
Q: Are these tags waterproof?
A: Yes. The TPU body is rated IP68 — fully sealed against water and dust. The tags survive rain, mud, and high-pressure washing without damaging the chip.
