# Long Range RFID Card: Revolutionizing Access Control and Asset Tracking ## What Are Long Range RFID Cards? **Long range RFID cards** are advanced identification devices that utilize radio frequency technology to enable contactless reading from distances significantly greater than traditional proximity cards. As someone who has managed large-scale facility security, I've personally witnessed the transformative impact these cards have on operational efficiency. The ability to grant vehicle access to authorized personnel without requiring them to roll down windows—especially during harsh weather—has been a game-changer in our security protocols. ### Technical Specifications and Performance Metrics Based on my experience evaluating multiple systems, here are the detailed technical parameters for a typical **long range RFID card**: * **Operating Frequency:** 860 MHz - 960 MHz (UHF Band), commonly using 915 MHz in the Americas. * **Read Range:** 3 meters to 15 meters (approximately 10 to 50 feet), depending on the reader's power and environmental conditions. * **Chip Type:** Impinj Monza R6, Alien Higgs-3, or NXP UCODE 7/8 series are prevalent. A common chip code is `Impinj Monza R6-P`. * **Memory Capacity:** Typically 96-bit to 512-bit EPC memory, with 64-bit TID (Tag Identifier) and optional 512-bit user memory. * **Card Dimensions:** Standard ID-1 format: 85.6mm x 54.0mm x 0.76mm (ISO/IEC 7810 standard). Thickness can vary with material. * **Protocol Standards:** Compliant with EPCglobal UHF Class 1 Gen 2 (ISO 18000-6C) protocol. * **Power Source:** Fully passive, powered by the RF signal from the interrogator (reader). * **Data Transfer Rate:** Up to 640 kbps. * **Operating Temperature:** -25°C to +70°C. * **Re-write Cycles:** 100,000 cycles minimum. * **Data Retention:** Up to 50 years. > **Important Note:** The above technical parameters are for reference and represent common industry benchmarks.
