Toll fare Touch 'n Go can be used on entire highway stretches in Malaysia with the familiar TnG & TAG sign marked on the road. Two systems were introduced for toll fare collection instead of manual tickets. Due to highways with numerous junctions or intersections serving short-distance trips, most of Malaysia's highways use open system toll collection. Toll fare collection on open system Card users only have to touch the reader at Touch 'n Go lane counters or drive-through SmartTAG lanes at certain toll plazas. Toll fares charged are fixed regardless of the distance travelled. 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. SmartTAG An extension of Touch 'n Go is the SmartTAG or TAG onboard unit, which allows users to insert the card into a reader device installed in the vehicle for fully automatic/non-stop payment at toll plazas. Payment is made automatically as the toll charge is deducted from the value stored in the Touch 'n Go card. Electronic toll collection systems There are three types of the electronic toll collection (ETC) systems, Touch 'n Go card unit, Smart TAG onboard unit and RFID tag. Touch 'n Go and Smart TAG have been made compulsory in all expressways since 1 July 2004, following the instruction of the Works Minister, Datuk Seri S. Samy Vellu.
