E-ZPass Is the Best Tracking Device That's Already in Your Car

E-ZPass is probably the best thing that's ever happened to paying tolls. Those plastic funnels you toss coins into are a close second. But E-ZPass has a bonus feature. It can be used to track you everywhere you go.

E-ZPass uses RFID. It's cool tech, but hackable and trackable in ways that the companies who use it don't really want anyone to talk about. E-ZPass RFID tags, for instance, can be scanned in plenty of places that aren't tollbooths. A hacker known only as "Puking Monkey" has shown that it happens all the time around the streets of NYC, and talked about his findings at DEFCON.

To test how often his E-ZPass RFID tag was getting polled, Puking Monkey wired a little mooing cow toy into the circuit so it would warn him whenever something happened. And in a short drive around Manhattan, PM found his cow mooing an awful lot for no immediately discernible reason.

Turns out though, that this was the result of a project called Midtown in Motion, a New York City traffic management system that is using E-ZPass RFIDs to track cars through the city center. It's not exactly clear what kind of information the Department of Transportation is scraping, but it's something. And all you have to do to be involved is have an E-ZPass hanging around.

Forbes reached out to the E-ZPass Inter-agency Group—the folks who oversee E-ZPass in the 15 states where it operates—and apparently NYC is the only place that uses them for any sort of tracking. Officially. So far. Real-time traffic monitoring isn't particularly nefarious on its own, but post-PRISM it's easy to get paranoid metadata-harvesting and it can be a little unnerving to know your car is a big fat target for tracking.

Maybe it's time to pick up an RFID-proof holster. You know, just in case. [Forbes via Slashdot]

E-ZPass blows! My family up in PA has it and you're supposed to slow down to 5 MPH when going through the toll lane. Wow, what a convenience! Compare that to blowing through the toll lanes in TX at the posted speed limit of 85 MPH with a TXTag.

If I'm being tracked everywhere that I go, I might as well get some benefit. Like them taking money automatically out of my account faster.

Yes, I did read the article and it looks like they could track your tag no matter where you're driving if they wanted to do so.
