RFID chips are already well beyond the
embeddable-anywhere threshold, but the breakthrough Hitachi's planning to show off at this year's ISSCC (International
Solid-State Circuits Conference) is their newest mu-chip, an RFID tag that's a mere 0.15 x 0.15 millimeters, and 7.5
microns thick -- ten or more times thinner than a sheet of paper with all the 128-bit identifying goodness we've to
know and love / loathe. Ah, just think of the possibilities of embedding these things all the places their previous,
positively bloated 0.3 x 0.3mm / 60 micron thick chip wouldn't go (pictured right is the even more obese 0.4 x
0.4mm version). Ahem.
