FASTag is a simple to use, reloadable tag which enables automatic deduction of toll charges and lets you pass through the toll plaza without stopping for the cash transaction. FASTag is linked to a prepaid account from which the applicable toll amount is deducted. The tag employs Radio-frequency Identification (RFID) technology and is affixed on the vehicle’s windscreen after the tag account is active. FASTag is a perfect solution for a hassle free trip on national highways. FASTag is presently operational at 470+ toll plazas across national and state highways. More toll plazas will be brought under the FASTag program in the future.
