Electronic pass for toll road: where you are heading to, or even your entire journey if throughout the itinerary, there are traffic cameras and auto toll collection pointsCCTV: inside building, public areas, dashcam in vehicles nearbyCredit card: traces back to your identify, location, amount consumed, commodity purchasedHealth monitoring device: you wear in your body to capture your health data continuously, share in the technology provider's community if you wishOperating System: sharing the diagnostic data with the technology vendor when problem occurs or during online trouble shootingWeb site cookies: IP address to geo-location of your web surfing location, your web preferenceDigital photo: modern cameras are equipped with geo-tagging
