<h1>ISO 15693 NFC Tag: A Comprehensive Guide</h1> <p><strong>ISO 15693 NFC tag</strong> technology has been a cornerstone of my professional work in RFID systems for years. From my personal experience, its balance of read range and data capacity makes it uniquely versatile for countless applications. I've always had a knack for understanding wireless protocols, and dissecting the capabilities of the ISO 15693 standard was a particularly rewarding skill to develop.</p> <h2>Technical Specifications and Parameters of ISO 15693 NFC Tags</h2> <p>In my opinion, to truly leverage this technology, one must understand its core technical parameters. Below are detailed specifications for a typical high-performance <strong>ISO 15693 NFC tag</strong> module. *Please note: These technical parameters are for reference data; specifics need to contact backend management.*</p> <h3>Chip and Memory Details</h3> <ul> <li><strong>Standard Protocol:</strong> ISO/IEC 15693, ISO/IEC 18000-3 Mode 1</li> <li><strong>Operating Frequency:</strong> 13.56 MHz ± 7 kHz</li> <li><strong>Chip Model:</strong> NXP ICODE SLIX 2 (ICode ILT)</li> <li><strong>Memory Type:</strong> EEPROM</li> <li><strong>User Memory Size:</strong> 2,048 bits (256 bytes)</li> <li><strong>Unique Identifier (UID):</strong> 64-bit (8 bytes) serial number, factory-locked</li> <li><strong>Data Retention:</strong> > 50 years</li> <li><strong>Write Endurance:</strong> > 100,000 cycles</li> </ul> <h3>Physical and Performance Parameters</h3> <ul> <li><strong>Typical Read Range:</strong> Up to 1.5 meters (with appropriate reader power)</li> <li><strong>Typical Write Range:</strong> Slightly less than read range</li> <li><strong>Anti-Collision:</strong> Supports dynamic frame slot (DFS) for reading multiple tags simultaneously</li> <li><strong>Data Transfer Rate:</strong> High data rate (26.48 kbit/s) or Low data rate (6.62 kbit/s)</li> <li><strong>Modulation:</strong> 10% or 100% ASK (Reader to Tag), Manchester/PSK (Tag to Reader)</li> <li><strong>Common Form Factors & Dimensions:</strong> <ul> <li>Label/Sticker: 50mm x 50mm x 0.2mm</li> <li>PVC Card: CR80 format (85.6mm x 54mm x 0.76mm)</li> <li>Disc Tag: 30mm diameter, 2mm thickness</li> <li>Glass Capsule: 12mm length, 2.12mm diameter</li> </ul> </li> </ul> <h2>Prac
