<h1>RFID Card Design: A Comprehensive Guide</h1> <h2>My Journey into RFID Card Design</h2> <p>When I first started working with <strong>RFID card design</strong>, I was fascinated by how a simple card could unlock doors, make payments, and manage access. My personal experience began with a university project where we had to design a student ID system. The challenge wasn't just the electronics; it was creating a card that was durable, secure, and aesthetically pleasing. This project taught me that successful <strong>RFID card design</strong> is a blend of engineering, material science, and user experience design. I discovered a personal aptitude for balancing technical specifications with practical, human-centric design, which has become a cornerstone of my professional skill set.</p> <h3>Technical Foundations: Components and Parameters</h3> <p>A robust <strong>RFID card design</strong> hinges on its core components. The design must integrate an antenna, a substrate, and most critically, the RFID inlay or chip. Here are detailed technical specifications for a common high-frequency (13.56 MHz) card, often used in access control and payment systems. <em>Please note: These technical parameters are for reference data; specifics need to contact backend management.</em></p> <h4>Detailed Technical Specifications for an HF RFID Card</h4> <ul> <li><strong>Chip Model:</strong> NXP MIFARE Classic EV1 1K (MF1S50YYX_V1)</li> <li><strong>Operating Frequency:</strong> 13.56 MHz</li> <li><strong>Memory:</strong> 1 KB EEPROM, organized into 16 sectors with 4 blocks each.</li> <li><strong>Communication Protocol:</strong> ISO/IEC 14443 Type A</li> <li><strong>Data Transfer Rate:</strong> Up to 424 kbit/s</li> <li><strong>Dimensions (Standard CR80):</strong> 85.60 mm × 53.98 mm × 0.76 mm</li> <li><strong>Antenna Design:</strong> Etched aluminum or copper coil, typically 3-5 turns, with a designed resonance for 13.56 MHz.</li> <li><strong>Substrate Material:</strong> PVC, PET, or Polycarbonate (0.76mm standard thickness).</li> <li><strong>Operating Temperature:</strong> -25°C to +70°C</li> <li><strong>Read/Write Distance:</strong> Typically up to 10 cm, depending on the reader.</li> </ul> <p>My
