Pervasive computing goes the last hundred feet with RFID systems

I examine a class of pervasive computers: radio frequency identification tags. RFID tags turn everyday objects into network nodes that uplink IDs and status data to enterprise databases, storing new information as needed. They literally vanish into commonplace objects, offering efficiencies in handling, location, and condition tracking. However, some people caution that we must implement privacy and security features from the ground up to avoid covert reuse of the tags.
