EZid LLC products

The EZid rumen bolus has been developed to permanently identify ruminants with an ID bolus that lodges in the reticulum. The EZid bolus features ISO 134.2 kHz HDX (half duplex) electronics sealed within biocompatible ceramic. It is engineered to provide a sophisticated, tamper proof, yet economical method of employing radio frequency for permanent, positive and safe identification. The EZid bolus exemplifies superior performance, reliability and long term retention. We recommend the bolus when positive identification is important. The EZid rumen bolus is administered with an appropriate sized balling gun. The bolus can be scanned and read by high performance ISO compliant readers comparable to the Avid Power Tracker VII handheld reader and Dual-Mode stationary reader.

This RFID tag is available in official USDA 840 numbers or standard ISO numbers.  Overall tag size is 1 1/4 inches by 1 1/4 inches.  

We offer a full line of visual ear tags and RFID systems for cattle, sheep, goats and swine.

EZid USDA and standard microchips and PIT Tags feature AVID electronics. Through the use of patented technology*, AVID has pioneered the use of miniaturized implantable transponders. Today, more than 15 million AVID microchip transponders have been successfully administered worldwide.
