I have the original sunpass with the LCD screen that showed your balance.
Well I just got a notice in the mail that they're doing away with the balance feature on them, so now they're as useless as the sticker. Got to go online for updates. Even though I have the automatic update to my CC, it's nice to see how much is left when I go through tolls.
So when mine finally dies, I guess it's the sticker for me.
