Do any companies offer such a product—and, if so, where are they located?

The only company of which I am aware is Somark, which manufactures RF inks for animals (see RFID Tattoos to Make a Mark on Cattle Tagging). The permanent animal-identification system works by tattooing each animal with dielectric ink. Data is encoded in the tattoo, and can be read remotely using a Somark interrogator.
If any of our readers know of other businesses that produce RF ink, please post information below.
