Invisible 'Radio' Tattoos Could Identify Soldiers
By Bill Christensen

Somark Innovations announced biocompatible RFID (Radio Frequency
Identification) ink, which can be used to tattoo cattle and laboratory
rats and can be read through animal hair.

It might even be used on humans eventually.

This is a passive RFID technology that contains no metals; the tattoos
themselves can be colored or invisible.

The Somark ID System creates a "biocompatible ink tattoo with chipless
RFID functionality."

The RFID ink tattoo does not require line of sight to be read, as is
the case with other RFID devices (making them better than a barcode for
some applications).

RFID ink tattoos also solve the annoying problem of ear tag retention.
Conventional RFID ear tags sell for about $2.25; about 60-90 percent of
them eventually fall off. Also, Somark claims that the biocompatible
RFID ink system will improve readability rates as well.

Somark Innovations co-founder Mark Pydynowski noted that the RFID ink
is fully biocompatible and was safe for use in humans. He noted that
RFID ink tattoos could be used to track and rescue soldiers. "It could
help identify friends or foes, prevent friendly fire, and help save
soldiers' lives," Pydynowski said.

Readers should note that VeriChip tags for patients are FDA approved

VeriChip tags have been proposed for immigrants

This technology reminds me of Jack Vance's spray-on conductive wire; it
also makes you think about the other possibilities that having an ink
that can be used to create a functioning circuit. You don't need to
tattoo it; you could print it onto flexible surfaces, like the sleeve
watch from the 1981 novel Dream Park.

Maybe now they can get that Dattoos skin circuit
