<h1>Tag RFID 13.56MHz: The Core of Modern NFC and Access Control</h1> <p><strong>Tag RFID 13.56MHz</strong> technology is ubiquitous in our daily lives, from contactless payments to secure building access. I personally experienced its convenience when I lost my office key fob but could still enter using my phone programmed with an NFC <strong>Tag RFID 13.56MHz</strong>. This sparked my interest in the underlying technology. My natural aptitude for understanding technical systems led me to explore how these tags work, and I firmly believe that their versatility is still underutilized by many industries.</p> <h2>Technical Specifications and Parameters of Tag RFID 13.56MHz</h2> <p>For developers and integrators, understanding the precise specifications is crucial. Here are detailed technical parameters for a common <strong>Tag RFID 13.56MHz</strong> product, specifically focusing on the popular NTAG213 chip series. *Please note: These technical parameters are for reference data; specifics need to contact backend management.*</p> <h3>Detailed Product Parameters (NTAG213 Example)</h3> <ul> <li><strong>Operating Frequency:</strong> 13.56 MHz (HF Band)</li> <li><strong>Communication Protocol:</strong> ISO/IEC 14443 Type A</li> <li><strong>Chip Manufacturer & Code:</strong> NXP Semiconductors, NTAG213</li> <li><strong>Memory:</strong> 144 bytes user memory, organized in 36 pages of 4 bytes each.</li> <li><strong>UID:</strong> 7-byte serial number (unique identifier).</li> <li><strong>Data Retention:</strong> Up to 10 years.</li> <li><strong>Write Endurance:</strong> Approximately 100,000 cycles.</li> <li><strong>Detailed Dimensions (Common Form Factor):</strong> 25mm diameter, round, with a thickness of 0.8mm. Adhesive backing is standard.</li> <li><strong>Read/Write Distance:</strong> Typically up to 10cm, depending on the reader's power and antenna design.</li> </ul> <p>I hold the opinion that while the NTAG213 is excellent for basic applications, projects requiring more memory or security features should consider chips like NTAG216 or DESFire. The choice significantly impacts the project's scalability.</p> <h3>Entertaining and Practical Applications of Tag RFID 13.56MHz</h3> <p>Beyond security, the <strong>Tag RFID 13.56MHz</strong> has fantastic entertainm
