 teddy,

This quote from the second article.  Plenty of info about this.

> Even within one type of RFID, however, there can be a wide array of read ranges. A passive ultrahigh-frequency (UHF) handheld reader has a range of about 10 feet, while a model using a beam-steerable phased-array antenna can interrogate passive tags at a distance of 600 feet or more.<
