CompTIA A+ Core 1 (220-1101) — Question 53

A technician receives a ticket that states a mobile payment device is having issues with its contactless payment feature. The device is not detecting payment options. Which of the following is the MOST likely cause of the issue?

Answer options

• A. NFC
• B. Bluetooth
• C. Wi-Fi
• D. Lightning adapter

Correct answer: A

Explanation

The most likely cause of the issue is NFC (Near Field Communication), as it is the technology specifically used for contactless payments. Bluetooth and Wi-Fi do not facilitate the same type of payment detection, and a Lightning adapter is unrelated to contactless transactions.
