Pig identification is mandated by the Australian Livestock Disease Control Act (1994) to prevent disease spreading and to maintain consumer confidence in the quality of Australian pork. Radio frequency identification (RFID) offers automated identification. Current RFID technology used to identify cattle and sheep is based on the low frequency (LF) system. This LF system is based on ISO 11785 and does not offer anti-collision capability. As small piglets may be in the RF field at the same time, tagging systems for piglets would require anti-collision sensitivity. This paper presents the use of high frequency (HF; 13.56MHz) and ultra-high frequency (UHF; 920 - 926MHz) RFID tags for pig tagging in Australia. The RFID tags designed and presented in thispaper can be attached to the pig's ear, offer anti-collision capability and are passive and reusable.
