Do you mean EZ pass? Check the website to see if your transponder is compatible with the FL system, if it is, then yes, just change the plate on your account. I have EZ pass for MA and do use it in FL. I change the plate information to a rental and enter the plate number before I leave the rental garage. You may need to buy your own velcro to affix it to the windshield (mine is not a suction cup) - don't forget to remove it when you turn the car in! And then change the plate back. Very easy!
