<h1>NFC Card Type</h1> <p>When I first started exploring the world of contactless technology, I was genuinely surprised by the variety and specific applications of different <strong>NFC card type</strong>s. My personal journey began with a simple access card for my office, but it quickly expanded into hobbies like collecting smart posters and even programming my own tags. This personal experience taught me that understanding the <strong>NFC card type</strong> is fundamental to leveraging the technology effectively.</p> <h2>Understanding the Core NFC Card Types</h2> <p>There are several primary <strong>NFC card type</strong>s, each with distinct capabilities. My personal view is that this specialization is what makes NFC so powerful. For instance, I have a natural aptitude for organizing technical details, so I've broken down the common types:</p> <ul> <li><strong>Type 1 Tag (Topaz):</strong> Often used for read-only applications like smart posters.</li> <li><strong>Type 2 Tag (MIFARE Ultralight):</strong> Common in disposable tickets or low-cost membership cards.</li> <li><strong>Type 3 Tag (FeliCa):</strong> Popular in Japan for transit and e-money.</li> <li><strong>Type 4 Tag (MIFARE DESFire):</strong> Used for high-security applications like access control and payment.</li> <li><strong>Type 5 Tag (Vicinity):</strong> Designed for longer read range applications.</li> </ul> <h3>Technical Specifications and Parameters</h3> <p>To make an informed choice, you need to consider the technical specs. For example, a typical <strong>NFC card type</strong> 4 product, like a MIFARE DESFire EV2 8K card, might have the following parameters. *Please note: These technical parameters are for reference only. For exact specifications, you must contact backend management.*</p> <h4>Sample Technical Data (Reference)</h4> <ul> <li><strong>Chip Code:</strong> NXP MF3DH(D)8x</li> <li><strong>Memory:</strong> 8192 bytes EEPROM</li> <li><strong>Communication Interface:</strong> ISO/IEC 14443 A</li> <li><strong>Detailed Dimensions:</strong> Standard ID-1 format (85.6mm x 54mm x 0.76mm)</li> <li><strong>Security:</strong> AES 128-bit encryption, 3DES, EV2 security architecture</li> <li><strong>Data Retention:</strong> > 10 years</li> <li><strong>Write En
