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.
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.
Texas Instruments 134.2 kHz LF RFID uses frequency modulation and half duplex techniques. This unique approach gives the most robust performance and best 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.
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 authorized 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. In excess of 8 million tags have been deployed to date (2004).
