Well, the new wearable technology craze gives parents another option to keep tabs on their children. FiLIP looks like a watch but acts as a tracker and phone for parents. There is even an emergency button that kids can activate if they are lost or in trouble.
FiLIP costs $200 and does require a $10 monthly plan from AT&T.
