I'd recommend getting a Chargefox RFID card - makes the units a lot easier to use.
It would help if there was a mandated interoperability between the RFID cards. Having 5 different cards for 5 networks is nuts to the average punter trying to come to grips with this stuff.
I mean, we've got RMS etag in the car and it works with every tollway company in Australia. When the govt is handing out grants, it needs to start pulling a few levers. This should have been on the list.
