<h1>NXP NTAG 215: The Definitive Guide to Specifications and Applications</h1> <p><strong>NXP NTAG 215</strong> is arguably one of the most recognizable and widely implemented NFC Forum Type 2 tags in the world. From my personal experience in embedded systems design, its reliability and well-documented protocol make it a go-to choice for prototyping and production. I've found that its balance of memory capacity and cost is particularly well-suited for interactive marketing campaigns and product authentication.</p> <h2>Technical Specifications and Detailed Parameters</h2> <p>Understanding the precise capabilities of the <strong>NXP NTAG 215</strong> is crucial for integration. Below are the key technical indicators. *Please note: These technical parameters are for reference data; specifics need to contact backend management.*</p> <h3>Memory & Chip Architecture</h3> <ul> <li><strong>Chip Code:</strong> NT3H1101W0FHKH / NTAG 215 F</li> <li><strong>User Memory:</strong> 504 bytes (organized in 168 pages, 4 bytes per page). Page 0 to 3 are reserved for manufacturer data, serial number, and lock bytes.</li> <li><strong>Unique Identifier (UID):</strong> 7-byte serial number, extendable to 10 bytes with a 3-byte IC manufacturer code.</li> <li><strong>Data Retention:</strong> Up to 10 years.</li> <li><strong>Write Endurance:</strong> Typically 100,000 cycles.</li> </ul> <h3>Physical and RF Characteristics</h3> <ul> <li><strong>Communication Interface:</strong> ISO/IEC 14443 Type A, NFC Forum Type 2 Tag compliant.</li> <li><strong>Operating Frequency:</strong> 13.56 MHz.</li> <li><strong>Operating Distance:</strong> Up to ~10 cm (highly dependent on reader power and antenna design).</li> <li><strong>Common Form Factors & Detailed Dimensions:</strong> <ul> <li>Sticker (inlay): Often 30mm x 30mm or 25mm diameter. Antenna coil dimensions are critical and vary by manufacturer.</li> <li>PVC Card: ISO/IEC 7810 ID-1 format (85.6mm × 54.0mm × 0.76mm).</li> <li>Keyfob: Varies, but a common housing size is approximately 35mm x 35mm x 4mm.</li> </ul> </li> </ul> <h2>Personal Skill Application & Entertainment Use Cases</h2> <p>My personal skill in mobile app development allowed me to create a scavenger hunt game using <strong>NXP NTAG 215</strong> tags. We hid tags around a city park, each encoded with a piece of a puzzle or a clue. Participants used their NFC-enabled smartphones to tap and collect digital items, creating a highly engaging, real-world gaming experience.
