Hitachi develops RFID powder

Hitachi develops super-tiny RFID chips ---

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.

By relying on semiconductor miniaturization technology and using electron beams to write data on the chip substrates, Hitachi was able to create RFID chips 64 times smaller than their currently available 0.4 x 0.4 mm mu-chips. Like mu-chips, which have been used as an anti-counterfeit measure in admission tickets, the new chips have a 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.

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.
