Texas Instruments RFID (TI-RFID) low frequency (LF) RFID technology has been used to identify millions of livestock animals around the world.
These systems track meat and dairy animals, valuable breeding stock and laboratory animals involved in lengthy and expensive research projects.
The Australian National Livestock Identification System (NLIS) is the first and the largest implementation of RFID for animal tracking in the world.
RFID transponders are worn as ear tags or as an inter-ruminal capsule. Farm management can be fully automated for such processes as feeding, weighing, disease management, and breeding practices.
Low frequency (LF) RFID, with an operating frequency of 134.2 kHz, has been adopted internationally for animal identification applications following many years of development, exhaustive testing and practical field evaluation.
The International Standards Organisation (ISO) and the Australian/New Zealand standards for the electronic identification of animals are based on LF 134.2 kHz RFID technology.
(ISO11784/11785, AS5018/5019) The Texas Instruments LF RFID technology was selected by the ISO as the basis for these standards.
TI-RFID 134.2 kHz LF technology has been adopted by the NLIS in Australia after exhaustive field testing of all available technologies.
Through these trials the TI-RFID half-duplex (HDX) technology was demonstrated to have superior performance under practical conditions. NLIS tags have now been in use for several years, with great success.
Over a period of 10 years or more, suppliers of non-conforming technologies have challenged the use of LF RFID for livestock.
Despite these challenges TI's LF 134 kHz HDX RFID still delivers ideal cost: performance ratio for the livestock industry.
Texas Instruments 134.2 kHz LF RFID uses frequency modulation and half duplex techniques. This unique approach gives robust performance and good read-range in its class.
The tags are passive components (i.e. no battery), which combined with TI's legendary quality and reliability, means they continue to operate for many, many years.
Electro-Com is a leader in RFID technology.
The ISO standards also encompass full duplex (FDX) 134 kHz technology.
Although full duplex tags are cheaper and suppliers often claim that they will perform as well as HDX technology, these claims have not been supported during field evaluation with walk-through readers.
For this reason, HDX tags are used for livestock where performance and reliability are important. FDX tag performance is adequate where animals can be individually handled and scanned with hand-held readers.
TI HDX transponders used for livestock identification are factory programmed with a unique 64-bit code which is tamper proof and cannot be duplicated. All animal data is stored in secure data-bases where it can only be accessed by authorised users.
The leading suppliers of cattle identification products have now integrated TI-RFID technology into their ear tags.
Eartag manufacturers are carefully qualified by Texas Instruments, and must obtain ICAR (international) and NLIS approvals before releasing their products.
These tags are now being rolled out progressively in Australia, state by state, to support the NLIS implementation. Millions of tags have been deployed to date (2007).
