An article in EE Times has a misleading first sentence, but I think that the author is saying that Hitachi has figured out how to put an antenna on an RFID chip itself using some sort of bump technology, rather than requiring an external antenna.
I wonder what the range is.
Yes, new chip has its antenna within.

> I wonder what the range is.
Japanese press said that the range is several mm.

(article in Japanese.)
The Hitachi technology is really aimed at bank notes. Its on-board antenna has a tiny range - a few millimeters at best - and can only handle one chip at a time. I first met the Hitachi folks back in 2001, and they were talking about adding an external antenna even then: I am guesing this is what this article refers to, albeit obliquely.
