Passive RFID tags do not have an internal power supply and instead rely on the electromagnetic energy transmitted by the RFID reader to power their circuits and transmit data. Option B is incorrect as active RFID tags, which have an internal power supply, tend to have a shorter lifespan due to battery depletion. Option C is also incorrect as all RFID tags require an antenna to absorb signals. Option D is subjective and cannot be generalized as the reliability of RFID tags depends on various factors.
