The Touch 'n Go smart card is used by Malaysian toll expressway and highway operators as the sole electronic payment system (EPS). The credit card-sized smart card is made of plastic with Philips' MIFARE Classic microchip technology embedded in it. It is a one company monopoly system that you must use this card as long as you need to pass through the highway, take public transportation, etc in Malaysia. The card has an expiry date and inactive period. Check carefully as the Inactive card of not using for more than 12 months, cannot be reactivated. The Touch 'n Go systems are designed to process up to 800 vehicles per hour to ease the queue congestion at toll plazas and if used together with SmartTAG (a non-stop electronic toll collection system), will be able to process up to 1,200 vehicles per hour.

The official launch was at the Sungai Dua toll plaza and officiated by Rangkaian Segar Sdn Bhd's then-chairman, Datuk Dr Ramli Mohamad. The Touch 'n Go system was implemented in Cityliner Sdn Bhd, a stage bus service in Klang Valley in 2000. Touch 'n Go card users enjoyed discount fares of 10% when it was first introduced.
