Editing Radio-frequency identification (section)

===Animal identification===
RFID tags for animals represent one of the oldest uses of RFID. Originally meant for large ranches and rough terrain, since the outbreak of [[Bovine spongiform encephalopathy|mad-cow disease]], RFID has become crucial in [[animal identification]] management. An [[Microchip implant (animal)|implantable RFID tag]] or [[transponder]] can also be used for animal identification. The transponders are better known as PIT (Passive Integrated Transponder) tags, passive RFID, or "chips" on animals.<ref>[http://www.thenation.com/doc/20071231/pentland_gumpert USDA Bets the Farm on Animal ID Program]</ref> The [http://www.canadaid.com/ Canadian Cattle Identification Agency] began using RFID tags as a replacement for barcode tags. Currently, CCIA tags are used in [[Wisconsin]] and by United States farmers on a voluntary basis. The [[United States Department of Agriculture|USDA]] is currently developing its own program.

RFID tags are required for all cattle sold in Australia and in some states, sheep and goats as well.<ref>{{cite web|url=http://www.mla.com.au/Meat-safety-and-traceability/National-Livestock-Identification-System|title=National Livestock Identification System|publisher=Meat & Livestock Australia Limited|access-date=2013-09-03|archive-url=https://web.archive.org/web/20130820085741/http://www.mla.com.au/Meat-safety-and-traceability/National-Livestock-Identification-System|archive-date=2013-08-20}}</ref>
