The Scary Side of RFID
Radio frequency identification devices (RFID) are amazing if you're Wal-Mart
trying to keep track of thousands of pairs of Wrangler cargo pants, cheap TVs
and copies of the National Enquirer.
But with RFID devices getting smaller and smaller, there is also the potential
for abuse. Previously small enough to embed under one's skin, Hitachi now has
tags so small you can barely seem 'em. While this may prompt fears of RFID
tags stuck secretly in your hair, skin, or on your clothes, the antenna needed
to make it work is a monster -- over a sixth of an inch!
