Now that the commercial spend-fest that is a modern Christmas has passed, I thought it'd be a good time to discuss one of the more promising (as well as disturbing) commercial technologies now appearing on store shelves -- RFID (Radio Frequency IDentification). Maybe it's a godsend for commercial inventory control, maybe it's the biblical "Mark of the Beast..." In any case, this episode will give you a quick grounding in what RFID is, and how it can be used for both good and ill. Copious links to more detailed information are included, as always, in the show notes.
