Can RFID be this small?

Next time you reach for the pepper shaker, you may have to wonder if it has a little something extra in it. APPARENTLY Hitachi has developed powder-size RFID tags, the pictures of which are all over the internet showing this little spec on a finger and a bunch of specs around an enlarged human hair (example link). However, after an exhaustive search for a legitimate news item on this, I am beginning to wonder if this story is real. Maybe it’s because I reported on the chips in coins, which turned out to be untrue, but I’m just skeptical about this one.

The reported size is 0.05mm x 0.05mm and the suggested use is not actually for ingesting, but for anti-counterfeit measures.

If you have any information, links or opinions on the feasibility of these chips, please comment here.
