Requiring Chip for employment ? -- Feb. 21, 2006

Forcing employees to have a surgical procedure, however minor, in order to simply start a job sets a dangerous precedent for privacy and civil liberties, not to mention being immoral on its face.
RFID chip manufacturer VeriChip, however, claims readability on their product from up to 15 feet away. With readability from such a distance, suddenly it becomes feasible for a company to install RFID readers throughout its entire building so it knows where everybody is at all times.

And if a company can do it, why not a city? Why not a state, or the entire country? Tracking an entire population is no longer in the realm of science fiction

Implanting RFID chips may actually decrease security, not increase it.
An RFID device is dead most of the time since it doesn’t have its own internal source of power. Rather, the reader sends a burst of power through radio waves that turn on the device, and then a second signal sends a request for the device’s ID.
The thing is, anybody with enough patience to wait for someone to use the door can pick up this unsecured conversation with a simple directional antenna.

Or, if you have the signal broadcast by the door, you can program it into your own handheld reader and use it to trigger the unwitting employee’s ID tag. Presto! You have all the information you need to make your own CityWatcher data center RFID chip.

Homeland Security - 
New techniques in monitoring and sensing biological, chemical or radiation threats have been discussed that are similar to the deployment of "smoke alarms" within a building. Sensors that can detect low-levels of contaminants can quickly and easily be deployed permanently or in response to a potential threat. Leveraging the Sensicast Sensor Networking Platform, the sensors can provide a safety net of detection over a large physical area - indoors or outdoors.
