What is NFC? Your Ultimate Guide to How it Works and What it Does

Near Field Communication (NFC) is a short-range wireless technology that enables two devices, typically within a few centimeters of each other, to exchange data seamlessly without the hassle of pairing or using cables. It operates by creating a secure channel when two enabled devices come into contact or close proximity, allowing them to share information—from payment details to media files—quickly and efficiently.
