Touch 'n Go is introducing TNG RFID as a new electronic toll payment system that uses a TNG RFID sticker to pass through toll. The TNG RFID sticker, also known as TNG RFID tag, has an embedded radio frequency chip and is affixed to either the windscreen or the headlamp of the vehicle. It can only be registered and installed on a single vehicle.
As the vehicle passes through toll, an overhead scanner reads the radio-frequency from the TNG RFID sticker and charges the toll fare. The sticker will be linked to the user's Touch 'n Go eWallet from which the fare will be deducted.
