A company called All Flex is one of the leading providers of animal-tracking solutions. Biomark also specializes in animal identification. And there are many other companies that produce ear tags or subcutaneous tags.
Agriculture technology firm TekVet offers one of the few active RFID cattle-tracking systems. The TekVet system includes health monitoring and a Web site that displays details regarding an individual animal’s history and health condition. The system utilizes active 418 MHz RFID tags, sensors that monitor an animal’s internal temperature and transceivers to transmit each tag’s unique serial number, as well as the animal’s temperature, to an Internet server hosted by IBM. There, that tag’s unique serial number is linked with the specific animal and its health record (see TekVet-IBM Cattle Tracker Uses Active RFID Tags, Satellite Communication).
