# Yale RFID Door Lock: Advanced Security and Convenience ## Introduction to Yale RFID Door Lock Technology Yale RFID door lock systems represent a significant advancement in modern access control, combining Yale's legacy of security with cutting-edge radio-frequency identification technology. As someone who has installed and tested numerous smart lock systems over the past decade, I can confidently say that Yale's integration of RFID technology stands out for its reliability and user-friendly design. My personal experience with these locks began when I upgraded my own home security system three years ago, and the seamless operation has been impressive ever since. ## How Yale RFID Door Locks Work ### Core Technology and Operation Yale RFID door locks utilize passive or active RFID tags embedded in keycards, fobs, or even mobile devices to communicate with the lock's reader. When an authorized tag comes within proximity (typically 2-10 cm for passive systems), the reader captures the unique identifier and grants access if verified. What I've particularly appreciated is the system's consistency—unlike some Bluetooth or Wi-Fi locks I've tested, Yale's RFID technology rarely suffers from connectivity issues or false rejections of legitimate credentials. ### Personal Skill Application My background in electrical engineering has allowed me to understand and appreciate the sophisticated antenna design and signal processing within these locks. This knowledge helped me optimize installation positions in various buildings to minimize interference from metal doors or frames—a common challenge with RFID systems that many installers overlook. ## Technical Specifications and Parameters ### Yale RFID Door Lock Model YRD256-RFID Technical Specifications **Physical Dimensions:** - Exterior Assembly: 4.5" (114mm) height × 2.8" (71mm) width × 1.2" (30mm) depth - Interior Assembly: 5.1" (130mm) height × 3.2" (81mm) width × 1.8" (46mm) depth - Backset: 2.375" (60mm) standard, 2.75" (70mm) optional - Cross Bore: 2.125" (54mm) diameter - Door Thickness Range: 1.375" to 2.25" (35mm to 57mm) **RFID System Specifications:** - Frequency: 13.56 MHz (ISO/IEC 15693/14443 compliant) - Read Range: 1.5" to 3" (4cm to 8cm) depending on tag type - Chipset: NXP MFRC522 reader IC with Yale proprietary firmware - Encryption: 128-bit AES encryption for credential transmission - Memory Capacity: Stores up to 100 unique RFID credentials - Power: 4 AA alkaline batter
