HITACHI DEVELOPS RFID POWDER

RFID keeps getting smaller. On February 13, Hitachi unveiled a tiny, new “powder” type RFID chip measuring 0.05 x 0.05 mm — the smallest yet — which they aim to begin marketing in 2 to 3 years…At 5 microns thick, the RFID chips can more easily be embedded in sheets of paper, meaning they can be used in paper currency, gift certificates and identification.

But since existing tags are already small enough to embed in paper, it leads one to wonder what new applications the developers have in mind.
