How It Works
To participate, drivers sign up through the EZ TAG website, via telephone, or at one of the store locations. Next, the customers receive a small, white radio frequency transponder which must be affixed to the insides of their windshields behind their rear view mirrors. Finally, when passing through a toll plaza, drivers choose lanes specially equipped with sensors that can read EZ TAG transmitters and deduct the appropriate amount from their accounts.
Houston Transtar uses EZ TAG sensors, which are placed at numerous points across Greater Houston, for their Automatic Vehicle Identification (AVI) traffic monitoring system. By tracking the movement of individual transponder tags (EZ TAG user vehicles) over the city, the system can generate real time traffic information for use by the general public. The personal information about the EZ TAG customer is not compromised in this process because the EZ TAG database and the AVI system are not interconnected.

Famous quotes containing the word works:
“There is a great deal of self-denial and manliness in poor and middle-class houses, in town and country, that has not got into literature, and never will, but that keeps the earth sweet; that saves on superfluities, and spends on essentials; that goes rusty, and educates the boy; that sells the horse, but builds the school; works early and late, takes two looms in the factory, three looms, six looms, but pays off the mortgage on the paternal farm, and then goes back cheerfully to work again.”
—Ralph Waldo Emerson (1803–1882)
