[ Surely the market for RF sheilded passport sleeves is already gearing up.

Another poster left the following :

"The real concern is when data is read ligitimately from a reader (e.g. at passport control), there will be fortuitious far field emanations that can be detected at several hundred metres."

I believe I've had this discussion before and, while I haven't done the math myself, it seems that more than one person has discovered this issue. How difficult it is to glean meaningful data from those far field signals remains a question. Surely I'm less worried about detection at a relatively secure location like an airport, but actual copying of personal data is a concern.

I'd be interested in a cost comparison with technologies like smart card, ibutton, lasercard, etc. I know those RFID's are pretty damn cheap, but I think I'd happily pay an extra dollar for my passport to know that it wasn't broadcast capable. -k]
