Tags as small as a grain of rice have a unique identifier code, which can be read simply by waving a portable handheld microchip reader over the animal
Miniature, implantable transponder identification (ID) tags are designed for subcutaneous or intramuscular implantation.
Sterile ID tags are packaged individually, and non-sterile tags are bulk packed.
Each ID tag has a unique identifier code, and the code can be read simply by waving a portable handheld microchip reader over the animal.
The electromagnetic energy from a portable, handheld microchip reader sends a low frequency radio wave to the ID tag, and interprets the unique number of the ID tag.
All readers can 'read' the microchip ID tags from a distance of 7-17cm, and can decode ID tags from other manufacturers.
Pocket ID tag reader and computer compatible readers are available.
