Hitachi develops RFID Powder

[mexika]

RFID keeps getting smaller. On February 13, Hitachi unveiled a tiny, new “powder” type RFID chip measuring 0.05 x 0.05 mm — the smallest yet — which they aim to begin marketing in 2 to 3 years.
By relying on semiconductor miniaturization technology and using electron beams to write data on the chip substrates, Hitachi was able to create RFID chips 64 times smaller than their currently available 0.4 x 0.4 mm mu-chips. Like mu-chips, which have been used as an anti-counterfeit measure in admission tickets, the new chips have a 128-bit ROM for storing a unique 38-digit ID number.
The new chips are also 9 times smaller than the prototype chips Hitachi unveiled last year, which measure 0.15 x 0.15 mm. At 5 microns thick, the RFID chips can more easily be embedded in sheets of paper, meaning they can be used in paper currency, gift certificates and identification. But since existing tags are already small enough to embed in paper, it leads one to wonder what new applications the developers have in mind. Nox Defense Manufactures RFID “Dust” as Part of Invisible Defense Perimeter
Another prime example of how miniaturized surveillance technology is becoming. Nox Intelligent Perimeter Defense has produced, as part of a larger facility surveillance system, the aptly called ID-Dust. In this particular aspect of the defense system, tiny RFID chips are sprinkled on the floor of an access-restricted area, where they can be easily picked up by a target’s shoes. Working in tandem with video surveillance and hidden RFID readers, the dust provides a detailed log of a tagged person’s movements within a facility fitted with Nox’s security measures. RFID tagging, coupled with high-resolution video surveillance, creates a near-invisible defensive perimeter. Nox’s ID-Dust and other equally covert tags can be used to track anything from valuable electronics, hard-copy documents, to personnel. The RFID readers are clandestinely installed behind walls, floors, ceilings, and other inconspicuous places. Tagged objects/personnel are overlaid in real time on a map of the facility. The tags can be used to automatically prompt video cameras to begin recording when someone enters a monitored area, as well as to send alerts to security personnel. The system is currently being marketed to both government agencies and commercial companies. At least one report names the FBI as an “early adopter” of the system. Critics of such “Big Brother” surveillance methods are rightly startled. Nox’s grain-fine ID chips have the potential to turn any structure into a veritable surveillance sandbox. –Hooded Soldier
