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 process developed by Somark involves a geometric array of micro-needles 
and a reusable applicator with a one-time-use ink capsule. Pydynowski said it 
takes five to 10 seconds to "stamp or tattoo" an animal, and
there is no need 
to remove the fur. The ink remains in the dermal layer, and a reader can 
detect it from 4 feet away.

The ink also could be used to track and rescue soldiers, Pydynowski said.

"It could help identify friends or foes, prevent friendly fire, and help save
soldiers' lives," he said. "It's a very scary proposition when
you're dealing
with humans, but with military personnel, we're talking about saving soldiers'
lives and it may be something worthwhile."
