It is envisaged that citizens who do not have sufficient balance in Istanbulkart cards will be given the right to fall into negative balance for one time. It is planned that this right will be activated in cases where citizens do not have money on their cards and the toll used in the next balance loaded will be deducted. In this way, transportation will be able to continue without interruption. In case of failure to reload the Istanbulkart, all transportation cards of the citizens will be temporarily cancelled
