Cattle Identification Applications
The JIA-91D is designed for situations where cattle need to be identified individually by their electronic ear tag.
Typical uses include cattle registration, routine herd checks, breeding records, animal movement verification, and collecting tag IDs before transferring them to farm or livestock management software.
Its compact format is particularly useful when animals can be approached or restrained closely enough for short-range handheld scanning.
For operations that require scanning from farther away while cattle are moving through races or chutes, a longer stick reader or fixed reader may be more suitable.
The reader retrieves the electronic identification number stored in the tag. Animal history, ownership, weight, health, or breeding information is normally managed in a separate database or livestock management system.
Cattle Ear Tag Scanner FAQs
Does the JIA-91D support HDX cattle ear tags?
No. The confirmed supported formats for the JIA-91D are EMID and FDX-B.
If your cattle tags use HDX, another reader model with confirmed HDX support should be selected.
Can the scanner be used without a computer or phone connected?
Yes. Scanned tag IDs can be stored in the reader’s internal memory and transferred later.
This is useful when scanning cattle in areas where a computer, phone, or network connection is not immediately available.
What can affect cattle ear tag reading performance?
Tag size, antenna design, orientation, distance from the reader, surrounding metal, electrical interference, and the way the animal is positioned can all affect scanning performance.
For more consistent results, bring the reader toward the ear tag with a clear scanning path rather than relying on a single fixed angle.
