Smart-dust: Hitachi Develops World's Smallest RFID Chip.

Nicknamed "Powder" or "Dust", the surface area of the new chips is a quarter of the original 0.3 x 0.3 mm, 60µm-thick chip developed by Hitachi in 2003. And this RFID chip is only one-eighth the width of the previous model.

Hitachi expects this tiny size will open the way to new applications for wireless RFID chips. The RFID "powder" can be incorporated into thin paper, such as currency, creating so-called "bugged" money.

The RFID Loc8tor can identify special RFID tags from a distance of up to 183 meters (600 feet), and the RFID chips have GPS capabilities.

"By taking advantage of the merits of compactness, high authenticity and wireless communication, and combining it with Internet technology, the µ-Chip may be utilized in a broad range of applications such as security, transportation, amusement, traceability and logistics."
