Touch 'n Go is a contactless smart card system used for electronic payments in Malaysia. The system was introduced in 1997 and is widely used for toll payments on highways, public transportation, parking, and other services. The card is equipped with a radio-frequency identification (RFID) chip that allows users to make payments by simply tapping the card on a reader device. Touch 'n Go cards can be reloaded with funds either online or at designated reload kiosks. The system has become a popular and convenient way for Malaysians to make cashless transactions.
