Which of the following is a characteristic of NFC technology?

NFC (Near Field Communication) technology is indeed characterized by its ability to enable contactless payments. This functionality allows users to make transactions simply by holding their NFC-enabled devices, such as smartphones or smartwatches, near a compatible payment terminal. This contactless interaction enhances convenience and speed during transactions, which is one of the primary reasons why NFC is widely adopted in payment systems.

While NFC operates at a short range, typically a few centimeters, it works effectively for applications requiring close proximity, such as contactless payment, access control, and information transfer between devices. In contrast, other technologies, like Bluetooth, allow for longer ranges but are not specifically designed for contactless payments. Furthermore, NFC does not require line of sight, making it more user-friendly compared to some other communication methods. It operates on high frequency radio waves, specifically at 13.56 MHz, allowing for rapid communication between devices over very short distances.
