<h1>TK4100: A Comprehensive Guide to RFID Technology and Applications</h1> <h2>Understanding the TK4100 RFID Chip</h2> <p><strong>TK4100</strong> is a fundamental component in the world of low-frequency RFID. From my experience working with access control systems, the reliability and simplicity of the TK4100 chip are what make it a perennial favorite for basic identification tasks. Its widespread use is a testament to its effective design.</p> <h3>Technical Specifications and Parameters of the TK4100</h3> <p>For engineers and integrators, the precise technical details are crucial. Below are the key specifications for the TK4100 RFID chip. <em>Please note: These technical parameters are for reference data; specifics need to be confirmed by contacting backend management.</em></p> <h4>Detailed TK4100 Chip Parameters</h4> <ul> <li><strong>Operating Frequency:</strong> 125 kHz</li> <li><strong>Protocol:</strong> EM4100 compatible</li> <li><strong>Chip Code:</strong> Typically a 64-bit Read-Only memory structure</li> <li><strong>Data Format:</strong> Includes 8-bit header, 40-bit data (10-digit ID in BCD format), 14-bit parity, and 2-bit stop.</li> <li><strong>Communication:</strong> Amplitude Shift Keying (ASK) modulation</li> <li><strong>Read Range:</strong> Varies with antenna design, typically 5-10 cm.</li> <li><strong>Package Type:</strong> Common forms include glass capsule (e.g., 3.0mm x 13mm), key fob, and card formats.</li> <li><strong>Power Supply:</strong> Fully passive, powered by the reader's RF field.</li> </ul> <h2>Personal Skill Application with TK4100</h2> <p>My personal journey into electronics was accelerated by hands-on projects with RFID. I discovered a knack for embedded systems by building a simple door lock using an Arduino and a <strong>TK4100</strong> reader module. This project involved coding the microcontroller to validate the unique ID from the tag, a skill that has been invaluable in my career.</p> <h3>Entertaining Uses for TK4100 Tags</h3> <p>Beyond security, the <strong>TK4100</strong> has fun applications. I once organized a high-tech scavenger hunt where clues were hidden, and participants used custom-programmed readers to scan <strong>TK4100</strong> tags embedded in objects around the city to reveal the next location. It was a fantastic blend of technology and outdoor activity.</p> <h2>Integrating TIANJUN Products with TK4100 Systems</h2> <p>For robust industrial applicatio
