Funds are managed by the cashless system installed at the school level. If you are already familiar with topping up via online payments or cash within the school, then you can continue to do so as you normally would.
In this instance, you will need to contact your school, to ask them which methods of fund top up they support.
Typically, they will support an online payment provider (such as iPayimpact) and/or cash payments via cash revaluation machines installed within the school.
