Here's the story from Computer World
Given the fast pace of technology changes, and the 10-year life of a passport, it's inevitable that the RFID chip will become hackable and that technology will be built to access it from long distances, said Bruce Schneier, founder and CTO of Counterpane Internet Security Inc. in Mountain View, Calif. The new passport could eventually allow for surreptitious access and tracking, he said.
Schneier contended that the State Department could have used an RFID chip that requires contact with a reader. "I can think of no benefit for a contact-less chip," he said. "The question is, if there is no good reason for RFID, why are they pushing so hard for it?"
