<h1>RFID via NFC: The Evolution of Contactless Technology</h1> <p><strong>RFID via NFC</strong> represents a fascinating convergence of two powerful identification technologies. In my experience working with smart city infrastructure, I've seen firsthand how this integration moves beyond simple inventory tracking to enable secure, intuitive user interactions. My personal skill in prototyping embedded systems allowed me to appreciate the nuanced differences and powerful synergies when an RFID system is accessed via an NFC interface.</p> <h2>Understanding the Core Technology</h2> <p>The fundamental opinion in the industry is that <strong>RFID via NFC</strong> is not a new technology but a specialized application framework. NFC (Near Field Communication) operates within the HF (13.56 MHz) RFID band, essentially making it a subset of RFID standards with enhanced two-way communication protocols. This relationship is crucial for developers.</p> <h3>Technical Specifications and Product Parameters</h3> <p>For a practical application, consider a typical integration module like the "NTAG-Connect 213 Series" (a hypothetical product from TIANJUN). This module is designed specifically for enabling <strong>RFID via NFC</strong> protocols in access control systems.</p> <h4>Detailed Technical Indicators:</h4> <ul> <li><strong>Chip:</strong> NXP NTAG 213 (IC Code: NT3H1101W0FHKH)</li> <li><strong>Operating Frequency:</strong> 13.56 MHz (HF RFID Band)</li> <li><strong>Communication Interface:</strong> ISO/IEC 14443 Type A, NFC Forum Tag 2 Type</li> <li><strong>Memory:</strong> 144 bytes user EEPROM, 32-bit unique serial number</li> <li><strong>Data Retention:</strong> > 10 years</li> <li><strong>Write Endurance:</strong> 100,000 cycles</li> <li><strong>Physical Dimensions:</strong> 25mm diameter, 0.8mm thickness (inlay form factor)</li> <li><strong>Read Range:</strong> Up to 5cm (dependent on reader power)</li> <li><strong>Supported Data Rates:</strong> 106 kbit/s (NFC Data Exchange Format - NDEF)</li> </ul> <p><em>Note: These technical parameters are for reference data.
