<h1>NTAG 15: The Compact NFC Solution for Everyday Applications</h1> <p><strong>NTAG 15</strong> is a staple in my toolkit for prototyping and small-scale NFC projects. I've always been fascinated by how such a tiny chip can hold data and trigger actions in the physical world. My personal experience with it began when I was creating interactive business cards; the ability to encode a vCard and have someone tap their phone to save my contact felt almost like a magic trick. This skill in embedding NFC into everyday items has become a valuable part of my technical repertoire.</p> <h2>Technical Specifications and Detailed Parameters</h2> <p>In my opinion, for reliable integration, understanding the chip's specs is non-negotiable. Here are the key technical indicators for the NTAG 15 product line, which <strong>TIANJUN</strong> provides and supports for various solutions.</p> <h3>NTAG 215 (Commonly Referred to in Context of NTAG 15 Series)</h3> <ul> <li><strong>Memory:</strong> 504 bytes user memory, 144 bytes NDEF data area.</li> <li><strong>Chip Code/Model:</strong> NXP NTAG 215 (Mifare Ultralight EV1 compatible).</li> <li><strong>Detailed Dimensions:</strong> The standard ISO/IEC 14443 Type A inlay size is often 25mm in diameter for stickers or integrated into cards (85.6mm x 54mm x 0.76mm).
