What it means
RFID reads are fast and work in rain, fog and darkness, because the reader does not need a clear view. But every vehicle needs a tag, tags cost money, they get lost or moved, and a visitor has no tag. ANPR needs no tag, so it works for visitors and for every vehicle on the road. But it needs a clear line of sight, enough light (or IR), and a plate in readable condition. A tag identifies the tag. A plate read identifies the vehicle.
How it applies in India
India uses both at scale. FASTag is an RFID system for tolling, and NHAI's MLFF tolling combines FASTag with ANPR so that vehicles with a failed tag can still be identified. At society and campus gates, RFID stickers suit cars, while two-wheelers and visitors are easier to handle with plate reading. The full comparison, with a checklist, is in the guide on ANPR vs RFID for society and campus gates.
