Which of the following statement(s) is/are true regarding “FASTag” (RFID technology) used at toll plazas?
- It utilizes Active RFID tags that require an internal battery source to transmit signals to the toll reader.
- It operates on the principle of electromagnetic induction to exchange data between the vehicle's tag and the reader.
Choose the correct option from the following.
Correct answer: D
Explanation
Statement 1 is false — FASTag uses a PASSIVE RFID tag (energised by the reader's signal), not an active, battery-powered tag. Statement 2 is technically weak too: FASTag-style UHF RFID works through electromagnetic fields and radio-wave communication, so calling it 'electromagnetic induction' is imprecise. On a strict reading neither statement is correct → (D). (If the examiner used 'electromagnetic induction' loosely for electromagnetic communication, they might retain (B); but technically (D) is the sounder answer.)
