Question

You come to a security door and scan your airport identification but the door remains locked and the card reader flashes red.

a) Faulty card
b) Insufficient clearance
c) System malfunction
d) Unauthorized access attempt

Answer 1

If a security door at an airport does not open and the card reader flashes red, it could be due to a faulty card, insufficient clearance, a system malfunction, or an unauthorized access attempt.

Step-by-step explanation:

When you come to a security door at an airport and the card reader flashes red, several issues could be at fault such as a faulty card, insufficient clearance, a system malfunction, or an unauthorized access attempt. Security gates, as mentioned in the reference, are advanced systems capable of detecting metals and their positions.

Firstly, a faulty card could mean the magnetic strip or RFID chip is damaged. Secondly, insufficient clearance implies that the cardholder does not have the proper authorization to enter that specific area. Thirdly, a system malfunction could indicate a failure in the card reader or the database that verifies clearances. Lastly, an unauthorized access attempt would occur if someone is using a stolen or cloned card or otherwise trying to gain entry without permission.
