A new method of using radio frequency identification (RFID) technology to track livestock is ready for market.

Biocompatible Chipless RFID Ink, created by Somark Innovations, will initially be used by the livestock industry to identify and track cattle, mitigating export trade loss from mad cow disease scares.

Tests on cattle and laboratory rats proved that injecting the ink into an animal's skin to create an RFID "tattoo" is an efficient way to transmit information about livestock.

Secondary target markets include military personnel, laboratory animals, dogs and cats, and prime cuts of meat.
