Abstract

Near Field Communication (NFC) technology, as a short-range wireless communication method, enables secure and efficient data exchange between devices within a proximity of 10 cm. Leveraging its advantages in convenience and security, NFC has been widely adopted in mobile payments, smart access control, and IoT applications. This paper systematically explores the physical layer principles, protocol stack architecture, and security mechanisms of NFC, highlighting its performance superiority over RFID and Bluetooth. Through case studies of anti-counterfeiting, card emulation, and mobile payment scenarios, the research identifies key challenges such as transmission rate limitations and interoperability issues. Despite these challenges, NFC demonstrates significant potential in emerging fields like wireless charging and smart tourism. By optimizing chip design, strengthening encryption algorithms, and promoting cross-industry standardization, NFC is poised to become a critical infrastructure for the future Internet of Things (IoT) era.
