ZHEQOGZH Livestock Ear Tag Applicator

The ZHEQOGZH ear tag applicator is built for durability with a stainless steel clamp and alloy construction, designed to withstand farm conditions. It includes a replacement applicator pin and clamp, making maintenance straightforward. The tool suits various livestock ear tags, including cattle, sheep, pigs, and goats, and features a lock design to keep the pliers open or closed as needed. This device supports efficient tagging workflows on the farm, reducing tag placement time while maintaining tag integrity.
Compatible Sureflap Microchip RFID Collar Tags

These Sureflap-compatible microchip collar tags are designed for pets and small livestock identification, with a 1-inch diameter. While primarily marketed for entry control, their microchip format supports dependable ID across compatible systems. They work with SureFlap Microchip Pet Doors and related devices, enabling controlled access for animals, which can be useful in mixed-use farm environments where animal entry and exit tracking matters.
125khz RFID Proximity Fob Tags (T5577, Pack of 10)

These T5577 fob tags are blank out of the package and require writing data before use. They are rewritable and compatible with 125kHz systems, including various 26-bit formats. They are suitable for farms that rely on custom ID formats or require flexible data programming for livestock identification or access control. Not compatible with 13.56 MHz systems, please plan accordingly.
YARONGTECH 125kHz Writable Fob Tags (Pack of 10)

YARONGTECH offers a ten-pack of writable 125kHz T5577 fob tags. Each tag is rewritable and intended for use with 125kHz card writers. The chips require data to be written before use and are not pre-programmed, meaning they’re best for farms with a reliable writing workflow. They are compatible with standard 125kHz readers and support common 125kHz formats used in livestock tagging systems.
ETEKJOY Writable 125kHz Sticker Tags

ETEKJOY provides adhesive 125kHz tags in a round coin shape with a 25mm diameter. These blank sticker tags must be written with a 125kHz writer before use and can be affixed to non-metal surfaces. The adhesive backing makes them convenient for quick labeling of smaller animals, equipment, or crates, offering a flexible labeling option alongside traditional ear tags.
Buying Guide: Key Purchase Considerations
- Frequency and compatibility: Confirm whether your system uses 125kHz or 13.56MHz tags and ensure readers, writers, and collars are compatible across devices you already own.
- Durability and environment: For outdoor farms, look for rust-proof, weather-resistant tags and applicators designed to withstand dust, moisture, and temperature fluctuations.
- Data format and rewrite capability: If you need custom IDs or multi-format support, ensure writable T5577 or similar tags can store your chosen data formats (e.g., 26-bit or HID formats) and are truly rewritable.
- Ease of use: An ear tag applicator with a robust locking mechanism can streamline tagging while reducing pin or clamp breakage during routine use.
- Adhesive labels vs. ear tags: Sticker tags offer flexible labeling for small animals or temporary identification, but may not be as durable as ear tags for long-term use. Consider how you plan to manage records and whether you need permanent or semi-permanent labeling.
- Data management: A capable scanner, like the Tomotato unit, can store hundreds of IDs and transfer data via USB. Plan data handling workflows, backup, and integration with herd management software.
- Cost vs. value: While some items are entry-level (stickers, basic fobs), more durable ear tag tools and ISO-compliant tags may provide longer-term value by reducing maintenance and replacement needs.
- Regulatory compliance: Ensure your tagging and ID system aligns with local livestock traceability regulations and animal health monitoring requirements.
In summary, the right combination depends on your operation size, animal types, and data needs. A durable ear tag applicator paired with ISO-compliant or rewritable 125kHz tags can provide reliable, scalable livestock identification. For enhanced traceability, pairing a dedicated scanner with a mix of writable fobs and sticker tags offers flexible labeling across different farm scenarios.
