A customer is looking for a device that uses tap to pay when making purchases. Which of the following technologies should the customer use?

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?

I'm with you all on this one. NFC is the clear choice. Although I do wonder if any of the other options might work in a pinch, like using Bluetooth to pair a device for payments. But NFC is definitely the way to go.

Absolutely, NFC is the answer here. It's become the industry standard for mobile payments and digital wallets. Tapping your card or phone to pay is all thanks to NFC.

Agreed, NFC is the way to go. Wi-Fi, IR, and Bluetooth aren't even close to being the right technologies for this use case. NFC is designed specifically for those quick, contactless payments.

This is a pretty straightforward question. The technology the customer is looking for is clearly NFC (Near Field Communication). That's the standard for tap-to-pay transactions.
