The process developed by Somark involves a geometric array of micro-needles and an ink capsule, which is used to 'tattoo' an animal. The ink can be detected from 4 feet away.

A startup company developing chipless RFID ink has tested its product on cattle and laboratory rats.
Somark Innovations announced this week that it successfully tested biocompatible RFID ink, which can be read through animal hairs. The passive RFID technology could be used to identify and track cows to reduce financial losses from Bovine Spongiform Encephalopathy (mad cow disease) scares. Somark, which formed in 2005, is located at the Center for Emerging Technologies in St. Louis. The company is raising Series A equity financing and plans to license the technology to secondary markets, which could include laboratory animals, dogs, cats, prime cuts of meat, and military personnel.
Chief scientist Ramos Mays said the tests provide a true proof-of-principle and mitigate most of the technological risks in terms of the product's performance. "This proves the ability to create a synthetic biometric or fake fingerprint with biocompatible, chipless RFID ink and read it through hair," he said.
Co-founder Mark Pydynowski said during an interview Wednesday that the ink doesn't ...   more »
