EID Readers and Tags

What Is EID?

Electronic Identification (EID) means individual animals can be tracked through their entire life cycle via an electronic ear tag. Over time, an animal’s lifetime data can be tracked, good and bad performers can be identified. The input of resources managed to ensure profits are maximised. EID Readers and Tags are the future of animal handling and management. This is evident from the mandatory EID tagging for sheep from June 2019. Our dairy industry is already using EID for dairy drafters, milking robots and automatic calf feeding systems, they are here and growing.

Many governments have implemented (or are planning to implement) mandatory EID schemes to help protect the industry from the impact of biosecurity threats. The Irish government have taken the first set to mandatory EID across all sectors within the sheep industry. The new rules will require all sheep sold from June 1, 2019, and onwards to be identified electronically. This time frame will allow farmers a reasonable period of time to use up stocks of tags on hand. Lambs under 12 months of age moving directly to slaughter from the holding of birth will also be required to be identified with a single electronic tag. With only €1 in the difference in price from a standard tag to an EID tag, it is well worth the small investment as it can make a farmers life a lot easier in the long run with far more management options.


Cattle/Sheep identification has both visual and management benefits.

By identifying your cattle individually with cattle ear tags, you (and others) can more easily determine which cow is which. In addition, being able to track an animal’s history and performance helps you determine which ones are performing well. With the use of a tag reader, weighing/drafting/sorting becomes a one person job with auto weight recording.


Using Electronic Identification (EID) ear tags can significantly speed up the weighing process. This help to reduce errors from a manual input and offer potential labour savings. When read by an EID reader, the EID tag automatically triggers the weigh scale indicator to recognise the animal, record the weight against it. This brings up other information relevant to the animal, depending on the level of indicator you are using.


Using Electronic ID tags has many advantages. One is that it offers another form of identification for each animal. Another plus is that an animal can be easily identified by scanning the tag with a reader, rather than needing to have the animal be completely still to read a visual tag number. Scanning EID tags rather than writing down EID numbers is a tremendous benefit in saving time and minimising errors. As cattle are being worked or loaded into a trailer, their EID tag can be scanned while they are on the move.

The fastest handheld readers in the world, Tru-Test EID stick readers also offer the longest battery life. Nothing should slow you down. All Tru-Test EID readers are 100% water and come with a 2-year warranty. Suitable for cattle and sheep applications.

ERS EID Handheld Reader

The ERS EID handheld reader is an entry level EID tag reader suitable for sheep and cattle. The ERS Handheld Reader is an economical way to read EID livestock tags. The reader can be used standalone using built-in memory to speed up recording for mandatory traceability schemes or sent directly to a Tru-Test indicator or printer via wireless Bluetooth® technology

ERS EID Handheld Reader

XRP2 Panel Reader

A Fixed Panel reader

The XRP2 is built around Tru-Test’s state of the art digital signal processing that gives optimum read range while automatically reducing unwanted interference.

Its revolutionary fast auto tuning provides maximum performance under all conditions. The fixed panel reader environment isn’t static. Small changes in the metalwork or the simple action of opening a metal gate on a crush or crate can affect the reader’s range and read speed performance. Tru-Test’s EID panel readers maintain optimal performance through these changing conditions by returning up to 18 times per second. Ensuring consistent, accurate tag reads throughout your weighing session.
