Hitachi Ups Ante on Counterfeiting

Scientists at the Hitachi Research Labs in Japan are raising the stakes in counterfeit protection technologies with the development of a new RFID (radio-frequency identification) tag. Measuring just 50 micrometers by 50 micrometers, these new RFID tags are smaller than grains of sand, and are in fact the smallest RFID tags ever devised.

The picture shows the powder chips beside a strand of hair. Though it isn't known if the hair is from a male or female - females have thinner hair strands than males - the powder chips still look pretty small.
“The so-called powder chip is thin enough that it can be mixed with paper pulp to add a layer of counterfeit protection to gift certificates, passports and currency. It's also caught the interest of the jewelry industry, which could invisibly embed the chip in rings and necklaces to track their origins, making them more difficult to sell illegally.”
Each chip, when stimulated by an RFID reader, emits its unique identification code. Each chip has its own distinctive 38-digit number. Since the code is part of the chip’s circuitry, counterfeiting is “impossible.” The powder chip was first introduced in February and is said to be available for commercial use by 2009.
