Infrared cards are used in hotel lodging after hours. Which option best describes this usage?

• A. During the day
• B. After hours
• C. During check-in
• D. Only in security offices

Answer: (B)

This question hinges on understanding what “after hours” means in an access-control context. Infrared access cards are used to grant entry during times when the front desk or other staff aren’t available, typically after regular operating hours. That means the scenario is describing access outside the normal daytime or staffed window, when guests still need to reach their rooms. So, the best description is after hours.

The other options don’t fit as well: using the cards during the day contradicts the idea of after hours; check-in is usually a staffed process during the hotel's daytime or early evening hours; and restricting the cards to security offices doesn’t describe the general lodging access scenario.
