This comes from Time Magazine, not the Paranoid Conspiracy News:

Radio-frequency identification — with track-everything-anywhere capability, all the time — is about to change your life.

In the not-so-distant future, RFID systems may monitor your money (to halt counterfeiters), your passports (to stop terrorists), the freshness of your food (to pinpoint spoilage), even your medicine intake (did you swallow that pill?).

Someday even you may carry an RFID. In Gulf War II, the Navy tracked wounded soldiers "like FedEx tracks packages," cutting down on battlefield confusion. Tag, you're it.

This is scary stuff. Read the whole thing, even though it's long. Make sure you remember the term--RFID. The fact that Corporate Amercia is throwing hundreds of millions at this new successor to the bar code, is particularly frightening.
