We may soon be sprinkling RFID chips like pixie dust in a few years because Hitachi has developed a tiny new type of RFID chip measuring 0.05 x 0.05 mm. Hitachi used semiconductor miniaturization technology and electron beams to write data on the chip substrates and they have a 128-bit ROM for storing a unique 38-digit ID number. Chips this small can be even more easily imbedded into paper currency, certificates, and identification. Hitachi hopes to market these power-like chips in 2 to 3 years but what other possible uses could such a small RFID chip have? Perhaps James Bond can implement RFID dandruff as a way to infiltrate villain hideouts-so long as he doesn't wear a black tux. [via Pink Tentacle]
