FYI. If you have multiple vehicles each under one RFID account name, all of them will be sharing credit. No need to load each one separately. The easiest way is to enroll in auto bank debit and have the account autoloaded when the balance is below 500.

The only issue I have with the RFID is that the system is still buggy. It will work in some toll booths and not with others. You have to report which toll booths aren't processing your RFID and wait for them to update their system.
