EZ Pass is by far one of the smarter things the DOT has done. Also, if you use it, you get like a dollar discount versus paying full price at a cash lane. I would recommend using a CC when signing up for one. So whenever you pass through one of those EZ Pass lanes, you won't get stuck at the tollbooth wondering why you can't get through. With prepaid ez pass, you gotta keep track of how much or how often you go through the ez pass lanes.
