context_page_description: 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 technology, and is also known as a PIT tag. Standard pet microchips are typically 11-13 mm long and 2 mm in diameter.
  Externally attached microchips such as RFID ear tags are commonly used to identify farm and ranch animals, with the exception of horses. Some external microchips can be read with the same scanner used with implanted chips.
