Depends where you live, none of the following apply where I live..:)
That makes the assumption someone isn't scanning those RFID credit cards as you walk in the door, which is very possible to do.
The local police now have license plate scanners and they know who parks where and can scan you while you're driving as well.
Not to mention those FastTrak things I have on the cars so we can zip thru toll booths without stopping and also paid use lanes. Now they're also being used to track traffic flow in a few places, which could identify where I am if they store that info.
In some places the government runs facial recognition software looking for criminals on the myriad of surveillance camera so anyone that's ever had a mug shot is being tracked.
Don't leave your mobile phone(s) on all the time..so the following doesn't apply either..
Plus the cell phone company knows exactly where you are at all times you have the cell phone turned on, wonder if they store that tracking information? I know for a fact that they can pinpoint the location of that phone within a few feet.
Just leaves ultra hi def sat..( both "top down" or "oblique" ) needs a clear sky though, to read "optically"..
But as my name isn't tattooed or painted on my body or head, ( I presume you don't have your name marked and sat readable on your person either ? ) the sat won't know who I am..nor who you are..:)
Of course if you've let them "chip" you and thus you can now be read with RF...
