I was searching the web a coupole of days ago and found a company called pfo that makes bracelets. First I thought it was normal bracelets, but when I looked closed I realised that it was trackable bracelets. That sounds really cool actually. This bracelet lets you track the wearer of it wherever he or she goes. So that's really good if you're worried. And the good part is that they look really nice as well. So they're not ugly or something. So I can really recommend that you take a closer look at this.
