Passports are HF 13.56 MHz
Pass cars are UHF 860 MHz - 960 MHz
UHF RFID tags indeed work at larger distance. That's how the pass card was designed. So it can be scanned at a border crossing with the person in the car holding it up. If you read more about the pass card you will learn that it has only a number on it that is referenced to a database at the border. Also, it COMES WITH A PROTECTIVE SLEEVE to be used when not in use. So, those morons in SF were running around with exposed Pass cards. Not with US PASSPORTS. Pass cards were not the question here and I remain with what I said, the US Passport Book will not be readable from more than 3 feet away because it is a HF tag.
I don't think these tags are a good idea, btw. I just wanted to chime in to calm some of the paranoia. Obviously that hasn't happened. 
I am done. This thread start to feel like PARF.

Seems to me that detection equipment will get much stronger over time.
Today's 10 foot range can easily be tommorow's 10 meter range and so on and so on..
