myPol is a location information service recently launched in Korea which lets you track anyone carrying the visiting card sized GPS transponder in real time. It is suitable for school children, working women and aged persons. Tracking is very simple and can be done from any computer connected to the internet, all you have to do is login to the myPol website and it will show the position of the subject accurately upto 1 meter on a map. It is obvious you cannot track your loved ones all the time so the GPS transponder has an emergency SOS button which once pressed relays your position to local authorities. The devie can be charged via a mobile phone charger.

myPol is a Korea only service and the unit sells for 160000 KRW ($ 170) and a monthly subscription to the service is 9000 KRW ($ 10).
