Common questions
What advantage does combining FASTag and ANPR give over either system alone?+
FASTag confirms the registered vehicle account tied to the RFID tag while ANPR independently reads the physical plate, so cross-checking the two catches cases such as a cloned plate, a tag moved to a different vehicle, or a plate mismatch that either system alone would miss.
What legal safeguard applies before this toll data is used in an investigation?+
Because the log covers routine movement of the general public, not just suspects, investigators access it under a formal request or court authorisation process rather than open querying, consistent with the data protection and proper-authority requirements that govern location data generally.
