It would be nice if they just had a reliable system that could assure you that as you have made an online topup that yes, your child will be able to get on the bus tomorrow morning and won't be left on the side of the road.
Just use the auto top-up system and you won't have that issue.
I do but it doesn't push the value onto the card so you don't "see it" until tagged at a reader (and the reader on the bus might not have been uploaded with the topup so it still doesn't become usable). An NFC push completes the whole process in one uninterruptable process/
Ah ok, my bad. I have mine set to top up $20 when the balance drops below $20, so I never have any issues.
