FASTag To reduce vehicular traffic at the toll plazas, the Government of India (GOI) has mandated all toll plazas, pan India, to make toll payments electronic. With this mandate, all vehicles travelling through toll plazas will have to mandatorily pay toll charges using FASTag. About fastag 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 407 toll plazas across national and state highways. More toll plazas will be brought under the FASTag program in the future.
