NFC
NFC (Near Field Communication) 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, ticketing systems, or IoT devices that require secure, proximity-based communication. It's essential for implementing features like tap-to-pay, contactless access cards, or data transfer between smartphones and tags, as it offers low power consumption and simple setup compared to other wireless technologies.
