From the Christian Science Monitor:
Soon, everything from children’s backpacks to the shoes you buy could be tracked by radio signal.
Nearly unknown a decade ago, a device the size of a pencil tip is beginning to infiltrate every corner and pocket of American life.
This recent technology – called RFID for “radio frequency identification” – is making everything from warehouse inventory to lost-luggage tracking to library checkouts easier, faster, and much more informed.
At the same time, the rush to harness the technology is raising a host of regulatory and other concerns, including the invasion of privacy, personal freedom, and civil rights. Those issues in turn are generating concern by lawmakers for how access to data collected by such methods should be limited and protected.
