Near Field Communication
Near Field Communication (NFC) is a short-range wireless communication technology that enables data exchange between devices when they are brought within a few centimeters of each other. It operates at 13.56 MHz and is based on RFID standards, allowing for contactless transactions, data sharing, and device pairing. NFC is commonly used in mobile payments, access control systems, and smart device interactions.
Developers should learn NFC when building applications for mobile payments (e.g., Apple Pay, Google Wallet), secure access systems, or IoT devices that require quick, low-power data transfer. It's essential for creating contactless solutions in retail, transportation, and smart home environments, where ease of use and security are priorities. Knowledge of NFC is also valuable for integrating with hardware like tags or readers in embedded systems.
