Sean Darks, CEO of CityWatcher, said the chips were like identity cards. He said the only difference is that they are inserted inside the person's body. He added they are very different from Global Positioning Satellite technology, which allows people's location to be monitored. Mr. Darks insisted that they were not dangerous and even decided to have a chip implanted in his own body. However, many people are worded about the issue of privacy. Many believe the technology could be abused and that new laws will have to be made. Mr. Darks said his workers always choose to have the chips removed.
