You knew this was going to happen sooner or later. In what has been classified as the first known instance of this practice in the U.S., CityWatcher.com has embedded RFID chips in two employees in order to control access to a room where security video footage is held. The company provides security cameras and digital video storage services for government agencies and the police. The chips were implanted in the upper right arms of the employees and then flashed in front of a reader to gain access to the aforementioned room.
Of course, this practice will raise questions by some over the rights of employees in the workplace as well as civil liberty issues. However, when you're dealing with sensitive files of this sort, where people face conviction of serious crimes, the thought of protecting evidence and making sure only authorized people have access to it may supersede the rights of a worker.
