Well, I have to send more of that article, because it gives a solution to the problem I have but also shows how some people are more privileged than others and can protect their kids, even though they share the planet with people like me. This is why other people don't seem to have the same problems, they are well protected...

"About the same time, the director of the Enterprise Charter School in Buffalo began using the electronic tags to monitor the movements of students. Every student has to wear an ID card containing the tag. When they arrive at school, the tag triggers a kiosk to record their presence and display their photos. The same technology is used in a Texas jail and on wristbands to track prisoners of war in Iraq. For the school, it's about security and efficiency. "Before, everything was done manually - each teacher would take attendance and send it down to the office," the school's director Gary Stillman told Wired.com. "Now it's automatic, and it saves us a lot of time."A firm called SAMSys Technologies, meanwhile, uses the tags to create an all-purpose surveillance tool for amusement parks called the SafeTzone System. Everybody at the park would get a SafeTzone Locator, a watch-size tracker. Parents could use it to find their kids on an electronic map, buy goodies for them without pulling out their wallets, and cut down on waiting times for rides. They bill it as a combination of gee-whiz and surveillance, in one tiny package. 'The SafeTzone System is making the entertainment park experience more enjoyable and less frustrating for families and groups.'"
