RFID 'Powder' - World's Smallest RFID Tag

http://www.technovelgy.com/ct/Science-Fiction-News.asp?NewsNum=939

The world's smallest and thinnest RFID tags were introduced yesterday by Hitachi. Tiny miracles of miniaturization, these RFID chips (Radio Frequency IDentification chips) measure just 0.05 x 0.05 millimeters.

The previous record-holder, the Hitachi mu-chip, is just 0.4 x 0.4 millimeters. Take a look at the size of the mu-chip RFID tag on a human fingertip.

The new RFID chips have a 128-bit ROM for storing a unique 38 digit number, like their predecessor. Hitachi used semiconductor miniaturization technology and electron beams to write data on the chip substrates to achieve the new, smaller size.

Hitachi's mu-chips are already in production; they were used to prevent ticket forgery at last year's Aichi international technology exposition. RFID 'powder,' on the other hand, is so much smaller that it can easily be incorporated into thin paper, like that used in paper currency and gift certificates.

Science fiction fans will have a field day with this new technology. In his 1998 novel Distraction, Bruce Sterling referred to bugged money:

They always played poker with European cash. There was American cash around, flimsy plastic stuff, but most people wouldn't take American cash anymore. It was hard to take American cash seriously when it was no longer convertible outside U.S. borders. Besides, all the bigger bills were bugged. (Read more about bugged money)

These tiny RFID tags could be worked into any product; combined with RFID readers built into doorways, theft of consumer goods would be practically impossible.

These devices could also be used to identify and track people. For example, suppose you participated in some sort of protest or other organized activity. If police agencies sprinkled these tags around, every individual could be tracked and later identified at leisure, with powerful enough tag scanners.

To put it in the context of popular culture, see the picture below, which was taken from the 1996 movie Mission Impossible. One of the IMF operatives places a tracking tag on the shoulder of a computer programmer. Pretty clunky-looking tag...

Take a look at these earlier stories related to RFID, and consider how much easier it will be with tinier chips: RFID Sensor Tag Shower For Disasters (gentle rain of RFID), RFID-Maki: Easy Payment Sushi (just tag the sushi directly, then scan customer's stomach [no joke, see digestible tags]) and VeriChip Chairman Proposes RFID Chips For Immigrants (just dust the border).
