Which of the following is a proximity identification device that does not require action by the user and works by responding with an access code to signals transmitted by a reader?
Correct Answer: B
Explanation/Reference:
Explanation:
System sensing access control readers, also called transponders, recognize the presence of an approaching object within a specific area. This type of system does not require the user to swipe the card through the reader. The reader sends out interrogating signals and obtains the access code from the card without the user having to do anything.
Incorrect Answers:
A: A passive system sensing device contains no battery or power on the card, but senses the electromagnetic field transmitted by the reader and transmits at different frequencies using the power field of the reader. This device does not send an access code. Therefore, this answer is incorrect.
C: A swipe card requires the action from the user; the user has to swipe the card. Therefore, this answer is incorrect.
D: A magnetic card requires the action from the user; the user has to swipe the card. Therefore, this answer is incorrect.
