Hitachi’s RFID powder freaks us the heck out
As if the various other permutations and teensyness of RFID weren’t wild enough, here comes Hitachi with its new “powder” 0.05mm x 0.05mm RFID chips. The new chips are 64 times smaller than the previous record holder, the 0.4mm x 0.4mm mu-chips, and nine times smaller than Hitachi’s last year prototype, and yet still make room for a 128-bit ROM that can store a unique 38-digit ID number.
