Buyer summary: Visual tags, RFID readers and applicators answer different purchasing questions. The selected readers list 134.2 kHz operation but different protocol lists. The selected applicators are described separately for one-piece and two-piece tags. Neither a protocol label nor a tag-type label proves every exact model combination will work.
An animal identification order can contain several parts that look related but require separate checks. A visual tag needs the right size and an appropriate applicator. An electronic identification request needs the tag's and reader's documented frequency and protocol. This guide separates those checks using existing ERRASONVET products rather than presenting them as one pre-validated kit.

Purchasing decisions to separate
- A visual ear tag can be mistaken for an electronic tag because it appears alongside RFID equipment.
- A one-piece tag can be paired with a tool listed for two-piece tags.
- Listed protocol support can be confused with certification or approval for a destination's official identification scheme.
Decide whether you need visible or electronic identification
The TPU ear-tag records in this comparison provide material and size information. They do not list an RFID function. Do not order them as electronic tags on the basis of their position in a broader identification category. For an RFID enquiry, provide the exact electronic tag model or specification you intend to read, even if you already know which reader shape you prefer.
Compare protocol lists, not just reader dimensions
Both selected reader records state 134.2 kHz. ERV-VI-ID-00002 lists ISO 11784/11785, FDX-B and HDX. ERV-VI-ID-00003 also lists FDX-A. This guide reports those catalogue entries; it does not independently certify protocol conformance or a tag-reader pairing. Confirm the exact tag and reader combination, interface and data workflow before selecting a model.
Keep reading-distance claims tied to conditions
The mini reader record lists an FDX reading distance of 17 cm and an HDX reading distance of 20 cm, with both dependent on the tag and operating conditions. Do not turn those values into guaranteed distances for every tag, orientation or installation. The stick reader's 60 cm length describes the device, not a 60 cm reading range. Where distance matters, request a test record for the intended configuration.
Separate one-piece and two-piece applicator enquiries
ERV-DF-ID-00009 is listed for two-piece ear tags. ERV-DF-ID-00010 is listed for one-piece ear tags. Compare the tag type and the tool description before requesting a specific pairing. Category-level matching is only the first check. Ask for confirmation of the precise tag model, pin and applicator combination rather than treating this table as a tested pairing matrix.
Clarify destination and data requirements
Tell the supplier your destination country and whether the purchase is for ordinary visual management or an official electronic identification programme. Ask for the applicable documentation rather than assuming acceptance from a protocol label. For readers, describe whether you need display-only reading, storage or transfer into another system. USB, Bluetooth, export formats and software compatibility are not established for these models by the reviewed specification fields.
Compare the listed specifications
Each table reproduces the listed fields for the linked SKU. An unlisted measurement or feature requires confirmation for that product; values from another row do not fill the gap.

Quotation checklist
- Visual or electronic identification requirement and exact product SKU
- Tag size and construction type; electronic tag frequency/protocol where applicable
- Reader protocol requirement and the specific tag to be checked
- Applicator, pin and exact tag-model pairing confirmation
- Interface/data workflow, quantities and destination-country documentary needs
Common ordering mistakes
- Pairing the one-piece tag with the two-piece applicator without checking.
- Treating the stick reader's physical length as reading distance.
- Turning a listed ISO protocol into a certification or country-approval statement.
- Assuming all readers offer the same storage, connection or software features.
Frequently asked purchasing questions
Are the listed TPU tags RFID tags?
The reviewed records describe visual ear-tag material and dimensions, not electronic functionality. Do not treat them as RFID tags without separate evidence.
Can the two readers read every animal tag?
No universal reading claim is made. Submit the exact tag frequency, protocol and model for confirmation against the selected reader.
Does the guide prove a one-piece applicator fits every one-piece tag?
No. This guide distinguishes the listed tool types. Confirm the exact tag model, fastening components and applicator pin before ordering; the type label does not establish a tested pairing.
What information is missing for the medium two-piece tag?
ERV-DF-ID-00003 lists small, medium and large options, but the reviewed specification table supplies dimensions only for the small and large options. The medium dimensions require confirmation.
