Word association: Work, home, Canada.

I have an RFID keyfob to get into my office. My apartment just installed them. Pretty soon, I'll need one to leave the country.

New passports issued by the United States have an electronic Radio Frequency ID chip in them containing well, exactly what the passport says. This is supposedly to help prevent forgeries and keep customs lines moving, since it's easier to hold an RFID to a reader than scan a barcode. Really.

Naturally, privacy advocates are still outraged, because with the right technology, any idiot can sit on top of a building in a foreign country with a high-powered RFID reader, a sniper rifle, and start picking off Americans one by one. Or, he could just steal your identity.

The Government has responded by including some metal in the passport cover so it can't be read while closed. Still, some are wrapping theirs in foil. What's even more troubling is that under new "security" procedures, you'll need a passport to enter the country by land if you're driving in from Canada. More links on this later, but I had so much trouble getting my building's front door to unlock with our new RFID tokens that I felt I had to say something about it.
