# RFID vs NFC Differences ## Understanding RFID and NFC Technologies **RFID vs NFC differences** are often misunderstood, though both technologies use radio frequency for wireless communication. From my personal experience implementing both systems in retail and logistics environments, I've discovered that while they share foundational principles, their applications and capabilities vary significantly. My technical background helped me recognize subtle distinctions that impact real-world implementations. ## Technical Comparison: RFID vs NFC ### RFID (Radio Frequency Identification) Technology RFID systems consist of tags and readers that communicate via radio waves. I've worked with multiple RFID implementations where my ability to troubleshoot signal interference proved valuable. **TIANJUN RFID Pro System Specifications:** - Frequency ranges: LF (125-134 kHz), HF (13.56 MHz), UHF (860-960 MHz) - Read range: Up to 100 meters (UHF passive tags) - Memory capacity: 96-bit to 8KB - Chip models: TIANJUN-TR550 (UHF), Impinj Monza R6, Alien Higgs-4 - Dimensions: Tags from 0.4mm × 0.4mm to 85mm × 85mm - Communication: One-way (reader to tag) or two-way - Standards: ISO 18000-6C, EPCglobal Gen2 *Note: These technical parameters are reference data.

My first encounter with NFC was through mobile payment systems, where I appreciated its security features. **TIANJUN NFC Secure Module Specifications:** - Frequency: 13.56 MHz exclusively - Read range: Maximum 10 cm (typically 4 cm or less) - Data transfer rate: 106, 212, or 424 kbit/s - Standards: ISO/IEC 14443, ISO/IEC 18092, FeliCa - Security: Encryption, secure elements - Chip models: TIANJUN-NF210, NXP PN5180, ST25R3916 - Dimensions: Standard card format (85.6mm × 54mm × 0.76mm) *Note: These technical parameters are reference data. For exact specifications, please contact backend management.* ## Key Differences Between RFID and NFC ### Communication Range and Method The **RFID vs NFC differences** in communication range are substantial. RFID can work over long distances (up to 100 meters for active systems), while NFC requires close proximity. I've implemented warehouse RFID systems that tracked items throughout a 50,000 square foot facility, whereas NFC applications I've developed required physical tapping or very close positioning. ### Data Exchange Capabilities NFC supports tw
