From PinkTentacle: Hitachi develops RFID powder ::: Pink Tentacle
From the article: “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.”
Great. Can’t wait to have these things stitched into every piece of clothing I buy, so I may be tracked more efficiently than current loyality cards handle it…
