The system was introduced in 1997 and is widely used for toll payments on highways, public transportation, parking, and other services.

The Touch 'n Go system was implemented in Cityliner Sdn Bhd, a stage bus service in Klang Valley in 2000.

Due to the need to further consolidate company operations, card users were required to pay full fare prices after 13 November 2003.

However, the Touch 'n Go card reader system on board buses was not well maintained by the bus operator.

Another subsidiary of Park May Berhad, City Profile Sdn Bhd, a feeder bus service (service known as Putraline) for PUTRA LRT was also introduced, and the system was successfully implemented until the Rapid KL bus revamp program took place.

The Touch 'n Go facility was also embedded in the Buy N Fly loyalty card rewards program for Malaysia Airlines' retail arm, Golden Boutiques Sdn Bhd's which was launched in December 1999.

A credit term of 30[5] days is given for post payment and fleet operators are able to monitor toll record/vehicle movement at highways via e-statement (itemised statement) after 24 to 48 hours from the time of transaction.

Touch 'n Go can be used on entire highway stretches in Malaysia with the familiar TnG & TAG sign marked on the road.

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.

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.

Since 2002, Touch 'n Go has been chosen as the common cashless ticketing system for all rail and bus lines in Klang Valley, in parallel with co-branded Rapid KL's My Rapid card (abolished in 2017) and KTM's Komuterlink (not using Touch 'n Go fare collection system).

It allows users to add the Touch 'n Go generic card number to more easily track their transactions.
