writes "According to Pink Tentacle, http://www.pinktentacle.com/2007/02/hitachi-develo ps-rfid-powder/ very tiny RFID chips 0.05mm x 0.05mm will be markted by Hitachi in the next couple of years. The many harmless uses generally involve embedding them in paper (money, gift certificates, admission tickets, etc.). The main specs are: "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." Telescreen: There will be absolutely no uses that involve privacy invasion nor should paranoia increase. Carry on...War is peace..."
