Compact, Reliable 134.2KHz Ear Tag for All Livestock Types
Designed for cattle, sheep, pigs, and goats. Built for farmers and government programs that need identification you can count on in every condition.
This RFID ear tag operates at 134.2KHz, the global standard frequency mandated by most national livestock traceability programs. Each tag carries a unique 15-digit electronic ID that can be read by any ISO 11784/785 compliant reader within seconds, without needing physical contact with the animal.
The outer shell is manufactured from food-grade TPU (Thermoplastic Polyurethane), which is soft on the animal's ear, won't crack in freezing temperatures, and resists UV degradation that causes cheaper plastic tags to become brittle. Our tags go through autoclave-level sterilization before shipping to prevent post-tagging infections.
Available in multiple colors for easy visual sorting by species, gender, or age group. We support custom laser printing of farm names, sequential numbers, QR codes, and logos directly onto the tag surface.
Why Choose SYNTEK for Your RFID Ear Tags?
Full In-House Production, No Middlemen
We own the entire production chain: copper wire winding, chip flip-bonding, TPU injection molding, laser engraving, and final QC. This is rare in the industry where most "manufacturers" actually buy semi-finished tags from others. Controlling each step means we catch defects at the source.
CE + ISO 9001 Certified
Our ear tags have CE and ISO 9001, this ensures your shipment passes customs and regulatory checks in the EU, Australia, South America, and Africa without hiccups.
Custom Mold Capability for OEM/ODM
Need a different shape for sheep vs cattle? Our in-house mold workshop can develop custom tag profiles in 10 to 15 days. We've made round, flag-style, and clip tags for customers across 130+ countries. You own the mold and the design.
17+ Years of RFID Manufacturing Focus
Established in 2006, we're not a new factory jumping on a trend. Over 17 years, we've shipped RFID products to 5,000+ clients in 130+ countries. Our animal tag production line has been optimized through tens of millions of units manufactured and field-tested.

Government Cattle Traceability Program, East Africa
The Challenge: Scaling to 500,000 Head of Cattle
A national agricultural ministry needed to tag over 500,000 cattle across dispersed rural areas as part of a disease control and export certification program. Their previous supplier's tags had a field failure rate of nearly 8%, with chips dying after exposure to the rainy season and tag numbers becoming unreadable within months. Replacement costs and re-tagging labor were eating into the program's already tight budget.
How SYNTEK's Tags Solved This
We provided our 134.2KHz LF ear tags with laser-engraved numbering and FDX-B encoding matched to the ministry's existing handheld readers. The secondary injection-molded TPU shell survived two consecutive rainy seasons without a single chip failure in the pilot batch of 50,000 tags. The ministry expanded the order to cover the full program.

FAQ
What's the minimum order quantity (MOQ) for custom ear tags?
Our standard MOQ for customized ear tags is 500 pieces. For standard products without customization, we can supply from 100 pieces. If you're working on a government program or large-scale project, we also offer volume pricing tiers starting at 10,000 units with additional discounts.
Will your tags work with my existing RFID readers?
Yes. Our 134.2KHz tags strictly follow the ISO 11784/11785 protocol, which means they work with any ISO-compliant reader regardless of brand, including Allflex, Agrident, Gallagher, Datamars, and others. If you're unsure, request a free sample batch and test it with your hardware before committing to a bulk order.
How long will the tags last in outdoor feld conditions?
Our TPU ear tags are designed for a minimum service life of 5 years in typical farm environments, including exposure to rain, mud, UV sunlight, and temperature swings. The chip itself has a data retention rating exceeding 10 years. Laser-engraved markings remain legible throughout the tag's lifetime, unlike printed markings that fade within months.
What's the difference betweenyour LF ear tag and UHF ear tag?
The LF 134.2KHz tag is the industry standard for individual animal identification per ISO 11784/785. It has a short read range (2-10cm) but provides highly reliable, interference-free reads, which is what government ID programs require. The UHF 860-960MHz tag offers a much longer read range (3-10m) and supports batch scanning of multiple animals simultaneously, making it better for inventory counting and logistics. Many farms use both: LF for official ID and UHF for daily management.
Canl get free samples to test before placing a bulk order?
Yes. We provide free samples for all standard products, you just cover the express shipping fee (usually $25-40 via DHL or FedEx). Tell us your reader model and the specific use case so we can encode the samples to match your system. Samples typically arrive within 5-7 business days.
Do you provide OEM/ODM services with custom mold development?
Absolutely. We have our own mold development workshop on-site, which means we can design and produce custom tag shapes tailored to your application. Mold development takes about 10-15 days. We handle the full process including material, color, chip type, shape, and packaging design. You own the mold and design rights.
How does your tag retentionrate compare to competitors?
Tag retention depends heavily on proper application, but our two-piece locking design is engineered to resist pull-out even when animals rub against fences or vegetation. In field tests across cattle and sheep operations, our retention rate consistently exceeds 97% over 12 months. We also supply compatible applicator tools that ensure correct installation angle and depth, which is the single biggest factor in retention.
What's the lead time for a standard bulk order of 10,000+ tags?
Standard production time is 10-15 working days for orders up to 50,000 pieces. For larger volumes or custom mold projects, lead time is typically 15-25 working days depending on the complexity. We keep common configurations in stock for faster turnaround on repeat orders.
