I came across this interesting article in the Canadian Business about inserting a "small buttonless brick of electronics about the size of a mobile phone that could, for example, be concealed in a child's backpack or sewn into a coat'. This device made by AirIQ will follow, track your child's whereabouts using a global positioning system (GPS) so you will always know where your child is.
I think it's a brilliant idea. Yes, I'm aware of the issue of invasion of privacy but for my peace of mind, it's a wonderful invention.
Watch for this company. I bet it's going to make million in the near future. Service to run by June (MyIQ) "will likely be sold online and via major retailers and probably start from $10 per month."
