Near Field Communication (NFC)

Near Field Communication (NFC) is a technology that allows two devices to communicate wirelessly when they are very close—usually within a few centimeters. It enables quick data exchange, such as making payments with a smartphone or exchanging contact information by simply tapping devices together. NFC operates at a high frequency and uses electromagnetic radio fields to establish secure, short-range connections, making interactions seamless and convenient without pairing or complicated setup. It's widely used in contactless payment cards, smartphones, and access control systems for quick and secure data transfer.
