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. One (1) Tag can only be registered and installed on a single vehicle.
As the vehicle passes through a toll, an overhead scanner reads the radio-frequency from the TNG RFID Tag and charges the toll fare. The Tag will be linked to the user's TNG eWallet from which the fare will be deducted from the TNG eWallet balance.
