What’s black and white and read all over?

A newspaper, but also a miniature plastic Holstein cow that a New Jersey man rigged to his E-ZPass to find out when the device was being monitored.

When the cow alarm goes off, it signals that the E-ZPass is being tracked.

According to a story on Forbes.com, the cow was mooing all over New York City, well past when the E-ZPass toll was paid.

Just on the six-tenths of a mile between Times Square and Madison Square Garden, the cow went off five times.

In the city, information is collected on vehicles with E-ZPass transponders so that traffic flow can be monitored, but license plate numbers or drivers are not revealed.

Still, the New Jersey motorist, described as an electronics tinkerer and identified by his internet handle, Puking Monkey, found the experience “intrusive and unsettling.”

This video shows the device "mooing" every time the hacked E-ZPass transponder is accessed.
