DART tags — valid?

Still running with a Dart Tag here, in fact got a new one last March, still beeps as you get to where the old Toll Booths were, had to return two that was allocated to vehicles that have moved on, told they could not be transfer to another vehicle. Dart Tag also commented it’s not a necessity but allows your account to update quicker, updates instantly where as with apnr only it can take up to 48 hours.
