Slashdot host a discussion regarding 7.5 micron thick RFID tags by Hitachi. From the EETimes article: "Hitachi has been pursuing such “embedded” applications for its “Mu-chip” for years. The company integrated an antenna on an earlier version of the chip in September 2003. In the latest version, the company has reduced the plan dimensions and the thickness of the chip."

Slashdot discuss the new extremely small RFID chips which open the way to new uses. I'm not sure about the validity of the source, can any reader confirm? This is the Slashdot summary: ""Hitachi has just come out with a new crop of RFID tags, measuring only 1/20 of a millimeter square. That's 1/8 the size (in linear dimension) of Hitachi's currently shipping mu-chips, which are 0.4 mm square. The new chip's width is slightly smaller than a human hair. These chips could put an end to shoplifting forever, but they could also be used by a governments or other entities to 'dust' crowds or areas, easily tagging anyone present without their knowledge or consent. Will someone come up with a surefire way of neutralizing chips that may be on your body or in your clothing?" Hard to pin down a source on this. The article cites another blog, which points to an article in Japanese." Update: 06/20 20:34 GMT by S : It seems this RFID "powder" could be used for jewelry monitoring.
