While some countries have not yet adopted the ISO (International Standards Organization) 11784, 11785 and 14223-1 for animal tracking, countries such as Canada, the United States, Australia, Europe and others have. As a direct result of this adoption any country wishing to export animals to these countries must have proper tracking and tracing records which mandate the use of RFID. Using a unique numbered RFID tag provides a very efficient method of identifying animals and collecting data far more quickly. Each unique RFID tag can be linked to a database that includes that animal’s specific information such as date of birth, inoculations, breeding specifics such as blood relation, and more. For livestock and other large animals we recommend our external FDX-B Ear Tag which provides read rates that are twice as fast as the HDXS tags. These cost effective external Ear Tags can be read by our Compact Flash (CF) reader that is easily inserted into any portable computer or PDA that has a compact flash slot. While this is a very useful reader for occasional reading our HDX-B paddle or HDX-B wand readers are hardier and provide additional features and functions that are not available on the CF HDX-B reader. The Ear Tags require the Ear Tag Tagger to correctly pierce and insert the Ear Tags. For smaller animals we recommend the bio-glass injectable tag. This injectable tag is available in both 125 kHz. and 134.2 kHz frequencies.
