Tracking your car just got E-Z-er.

Hacker that goes by the name of “Puking Monkey” has discovered that his EZ-Pass gets read in places far away from any toll booth.

TransCore, a company that makes the RFID readers that New York is using to pick up on E-ZPasses, was more forthcoming. A 2013 case study from the company notes that the $50 million project to improve traffic congestion in New York also involved the installation of a network of traffic microwave sensors, and has been successful enough that the city plans to expand it another 270 blocks.
