High-tech border pass raises alarm

Courtesy of Endgadget (that makes it legal for here, I think :))
3 U.S. border crossings "will employ high-tech radio frequency technology to monitor visitors from other countries who want to enter the States from Canada – a move that alarms both a Kingston privacy expert and an immigration specialist.*snip*..... Border guards will be able to access the information electronically from 12 metres away to enable those carrying the devices to be processed more quickly.
What was it Jefferson said? Oh I found it.
"Those who desire to give up freedom in order to gain security will not have, nor do they deserve, either one."

Does this concern anybody just from a privacy perspective, not to mention other illegal activities?

[UPDATE] Bruce Schneier weighs in on the RFID border issue here. I swear I blogged my posts before I went to Bruce's blog. (Noticing that we blogged about the same issues, though more depth in the other blog :P)
