Australian sheep and goats are required to have visually readable ear tags printed with a Property Identification Code (PIC). They are complemented by movement documents supplied by consignors that are used for identification and tracking. Very small ear tags are available for laboratory animals such as mice and rats. They are usually sold with ...
X-ray image of a microchip implant in a cat. A microchip implant is an identifying integrated circuit placed under the skin of an animal. The chip, about the size of a large grain of rice, uses passive radio-frequency identification (RFID) technology, and is also known as a PIT (passive integrated transponder) tag.
Alternatively, a chip plus a very large (125 mm square) antenna can be incorporated into the bib number worn on the athlete's chest at a height of about 1.25 m (4.1 ft). [ citation needed ] Passive and active RFID systems are used in off-road events such as Orienteering , Enduro and Hare and Hounds racing.
GPS animal tracking is a process whereby biologists, scientific researchers, or conservation agencies can remotely observe relatively fine-scale movement or migratory patterns in a free-ranging wild animal using the Global Positioning System (GPS) and optional environmental sensors or automated data-retrieval technologies such as Argos ...
In this scenario most of the costs of this expensive tracking system will fall on small farms and families, allowing corporate farms increased profits and lower costs. According to the USDA's NAIS User Guide (p27), [16] the cost of the various animal identification devices ranges from as little as $1 to as much as $20. For example, as indicated ...

In 2004, Tapemark announced a chipless RFID that will have only a passive antenna with a diameter as small as 5 μm. The antenna consists of small fibers called nano-resonant structures. Spatial difference in structure encode data. The interrogator sends out a coherent pulse and reads back an interference pattern that it decodes to identify a tag.
But in 2017, the league inserted a coin-sized microchip into its footballs. The chips unlocked a bottomless vault of data, and an ability to track the ball’s location. Initially, they weren’t ...
