When using phone, triangulation can be used to track your
location. When you use your NETs, credit card or ezlink, past
location can be tracked. When you login to a console, you can be
tracked via your IP address.
Think in Singapore, the datas are a little delayed, but can
still be tracked.
Look at all the junctions now, there are cameras....more and
more surveilance cameras are installed....
Mil-spec satelite can zoom in and see if your hair is messy on a
clear sky....countries near equator is harder cos too many low
lying clouds....but still possible.
WHo you wish to track? MSK?
