Not sure if the Dallas area does this but in Houston you can ask for a different type of toll tag. It mounts onto your license plate holder using the 2 license plate screws. I heard that they might not be available to all types of cars though. I'm not sure, I've only heard of it and seen it at my cousin's Mercedes dealership.
