Invisible RFID Ink Safe For Cattle And People, Company Says
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.
"This proves the ability to create a synthetic biometric or fake fingerprint with biocompatible, chipless RFID ink and read it through hair," he said.
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 amount of information contained in the ink depends on the surface area available, he said. The U.S. Department of Agriculture calls for a 15-digit number to track cattle. The first three digits are "840" for the U.S. country code. The remaining digits are unique identifiers. The numbers would link to a database containing more information.
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."
