What is a common use for a Near Field Communication connection?

A common use for a Near Field Communication (NFC) connection is as a contactless payment reader. NFC technology allows for secure communication between devices that are in close proximity, typically within a few centimeters. This characteristic makes it ideal for financial transactions, where the user can simply tap their smartphone or NFC-enabled card to a payment terminal to process a transaction. The convenience and speed of this process, along with the added layer of security it provides, have made NFC a popular choice for contactless payments in retail and other transactions.

In contrast, other options involve different technologies. Wireless audio streaming typically uses protocols like Bluetooth or Wi-Fi to transmit audio signals over a greater distance. Internet browsing requires a more robust data connection such as Wi-Fi or cellular networks, which NFC does not provide. File transfer over Wi-Fi also utilizes different protocols not associated with NFC. Thus, the versatility and specific capabilities of NFC make it particularly suited for contactless payments.
