To participate, a driver signs up through the EZ TAG website, via telephone, or at one of the store locations.
Next, the customer receives a small, white radio frequency transponder which must be affixed to the inside of their windshield behind their rear view mirror.
Finally, when passing through a toll plaza, the driver chooses lanes specially equipped with sensors that can read EZ TAG transmitters and deduct the appropriate amount from their accounts.
This range reduction is so much that not having a tag properly mounted will result in it not reading at all in toll lanes.
These characteristics are much different compared to the old battery tags, which would read fine if not mounted properly.
Despite the similarity in the names, EZ Tags are not compatible with the E-ZPass system in the northeast U.S.
