FASTag is a Radio Frequency Identification (RFID) technology-based electronic toll collection system in India. It streamlines toll payments on highways, offering a faster and cashless alternative to traditional toll booths. FASTag employs a prepaid account linked to a vehicle's license plate, allowing seamless passage through toll plazas. Users can recharge their FASTag accounts through various online and offline channels, promoting digital transactions and reducing traffic congestion. This initiative by the National Highway Authority of India enhances travel efficiency, decreases fuel consumption, and contributes to the vision of a more connected and digitally advanced transportation infrastructure in the country, aligning with the broader goals of the government's digital India initiative.
