RFID Ink Tattoo

Somark is a technology company located at the Center for Emerging Technologies and is
developing a proprietary ID system based on a biocompatible ink with chipless RFID functionality. The company has successfully tested RFID ink in animals, which proves that ink can be delivered and read. The primary application of the RFID ink is animal tracking in the livestock industry. ...

... "Somark announces the successful testing of Biocompatible Chipless RFID Ink in cattle and laboratory rats. The test proved the efficacy of injecting and reading a Biocompatible Chipless RFID Ink tattoo within the skin of animals. The technology will be initially leveraged to the livestock industry to help identify / track cattle and thus mitigate export trade loss from BSE (a.k.a. Mad Cow Disease) scares. Secondary target markets include laboratory animals, dogs & cats, prime cuts of meat, and military personnel. The company, which is currently raising a Series A equity financing, will license the technology to secondary target markets." ...

RFID Fibers in Currency Notes

An example of RFID Technology that can be woven into currency notes is the RFID Fiber... This vendor, INKode, has RFID technology that could be applied in the RFID currency tracking... Here is an explanation of how their technology works:

By embedding INKODE’s microscopic structured resonators into materials, then using extremely low power to energize them, these resonators will respond when excited by Radio Frequency waves. The resonators respond in a pre-determined manner.

These resonators can be embedded in paper products, glass, rubber, plastics and numerous other manufactured materials. The amount of RF energy needed to excite these truly passive devices is less than the amount of energy emitted by a keychain pocket flashlight.

This technology opens the door to a new perspective in automatic identification systems. INKODE calls the responses from these structures “Resonant Signature™." The use of these Resonant Signatures™ creates an unlimited variety for automatic identification.

This opens the door for RFID currency tracking through the use of RFID Fiber technology...

Other vendors are involved in the field of RFID fibers that could be applied to currency tracking:

Bsecure - anti-counterfeit, anti-diversion and brand protection: Bsecure turns MT amorphous microwire — Authentifiber — into a low-cost chipless RFID fiber for "smart" labels.

What is Chipless RFID?

Chipless RFID is a new class of low-cost radio frequency identity tags. They cost much less than $1 each, which means that these RFID tags are disposable and economical. The chipless tags, also known as RF fibers, are shaped as thin security threads, fine wires, and also as thin labels or laminates.

At modest volumes, the chipless RFID tags range in cost from 0.1 to 25 cents. Chipless tags can be applied in more diverse environments, because they work over a wider temperature range and are less sensitive to interference. And unlike chip tags, they can be implemented in thin packaging and labels and be invisible to the naked eye.

The benefits of chipless RFID are its low cost, thin and flexible profile, and agility over a range of environments.

Chipless RFID: RFID Fibers for Secure Applications

From RFID Journal ... 2004—Tapemark, a manufacturer of packaging and packaging materials, says it will use a new technology, called Chipless ID, to embed RFID transponders into ...

Tapemark Announces New Chipless RFID for Brand Protection

Because Chipless ID uses a frequency well above conventional UHF no chip is needed significantly reducing the cost of the RF tag as compared to traditional chip-based solutions. Tapemark's patented Chipless ID is ideal for applications such as authentication or product and package security and offers a unique serial number that can be tracked and traced from creation of the product through distribution....
