With RFID technology, you only have to get close to the "scanner," which both powers and interrogates the ID chip using radio frequency (RF) waves. This is seeing widespread use for things like inventory control, tracking packages, and road tolls. People in Spain are already having RFID chips implanted under their skin, so they can -- are you ready for this? -- skip the long lines at popular nightclubs. Preventing identity theft is a much more powerful rationale. Imagine the extent of people's voluntary cooperation if it became difficult to transact any business without it.
