A friend of mine told me that there are bracelets that you can put on their children. Tracking device... If she or he is going away so activates his bracelet so you get to know that it happened and where the child is through GPS. Or famous people who maybe are in a danger zone. Swedes abroad who work in risky countries. So nice that there are these kinds of fine products that can improve safety and can give families a relief. Think it's good and I would definitely recommend people to get the security that it brings. It's important to think through the possible risk scenario and make yourself a case-by-case basis. When secured one's life for the better.
