====Toll fare collection on closed system====
Card users "touch in" before entering the expressway at respective toll plazas and "touch out" at the exit toll plaza. Vehicle with cards have to drive thru TnG lanes and TAG lanes for SmartTAG users. Toll fares are charged based on the distance between the entry plaza and the exit plaza. Card users have to make sure the amount balance is more than RM20 before entering the toll plaza. Those with less than RM20 are required to top it up either at the offices or at TAMBAH NILAI lanes, otherwise they are unable to enter the highway. Seven expressways have the feature; the most famous is the North–South Expressway.
