Multi-Lane Free Flow (MLFF) tolling is a barrier-less tolling system. It enables transactions through reading of FASTag and Vehicle Registration Number (VRN) by High performance RFID Readers and ANPR Cameras. Once introduced, it'll provide seamless toll collection without stopping vehicles at fee plazas. The Centre is planning to introduce it at 25 National Highway fee plazas in FY 2025-26.
