Show Suggested Answer Hide Answer
Suggested Answer: D

NFC (Near Field Communication) is a wireless technology that allows devices to communicate and exchange data within a short range, typically a few centimeters. NFC is commonly used for tap to pay transactions, where a customer can use a contactless card or a smart device (such as a smartphone or a smartwatch) to make payments by tapping or hovering over a compatible terminal. NFC is different from other wireless technologies, such as Wi-Fi, IR (Infrared), and Bluetooth, because it does not require pairing, authentication, or network access to work. NFC is also faster, more secure, and more convenient than other payment methods, such as inserting or swiping a card.Reference:CompTIA IT Fundamentals (ITF+) Certification Guide, page 25;What is Tap to Pay and How Does It Work?

Haha, yeah, imagine trying to tap your card on a Wi-Fi router to pay for something. That would be a pretty strange experience. 'Excuse me, Sir, I'd like to use my Wi-Fi to pay for this coffee.'

Absolutely. NFC is the clear winner here. The only other option that might work is Bluetooth, but that requires pairing devices, which is a bit more hassle than just tapping your card or phone. NFC is just plug and play, you know?

Yeah, I agree. NFC is the way to go. Wi-Fi, IR, and Bluetooth are all wireless technologies, but they're not really designed for the quick, close-range transactions needed for tap-to-pay. NFC is specifically made for that kind of thing.

This is a pretty straightforward question. The customer is looking for a tap-to-pay device, and the obvious answer is NFC (Near Field Communication). That's the technology used in most contactless payment systems these days.
