FASTag is a simple to use, reloadable tag which enables automatic deduction of toll charges and lets the vehicles 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 360+ toll plazas across National and State highways.
