A New Jersey man hacks into his EZ tag and finds authorities are able to track your movements elsewhere.

Local Toll Road and TranStar officials insist none of your personal information is being used, only a partial code which they use to monitor traffic.  However, the toll road authority's Patti Evans says EZ tag can be tagged elsewhere.

“Some gated communities allow residents to use their own tags to get into the gate or they use them for parking structures downtown,” says Evans.

Its that fear of the unkown which concerns Terri Hall with Texans Uniting for Reform and Freedom.

“This is one of those thing we don't always consider,” Hall tells KTRH News.  “We just go sign up for the toll tag and don't realize what is really involved.”

TranStar's Dinah Massie insists the agency enforces strict rules against violating anyone's private, especially when it comes to freeway cameras.

“We even have a policy that says you cannot zoom in close enough to see what's in a car, you cannot take the camera and move it away from the freeway,” says Massie.

Still, Hall believes your information is stored somewhere, leaving it exposed to would-be hackers and identity thieves.

“If anyone can breach it, which we know it can be done, that means your information is vulnerable and your privacy is being invaded,” says Hall.  “Whether they like it or not, this is a reality we have to face.” 

Others point out if authorities really want to track you, they can simply use your cell phone to do it.
