Faread HF fixed tag readers FRD671-A8 is designed upon fully self-intellectual property.Based on proprietary efficient anti-collision algorithm, the series features excellent tag read/writeoperation performance with high identification rate. The series can be widely applied in many RFIDapplication systems such as Logistics, Personnel Identification, Conference Attendance, AccessControl, Anti-counterfeit, Jewelry Management, Self-service of Laundry and Industrial ProcessControl.
● Advanced anti-collision algorithm, high identification rate, typical tag process speed is over 80 tags/s;
● Support standard 50ohm RFID antenna with effective distance up to 90cm*;
● Antenna open/short circuit tolerant;
● Support Scan-mode①;
● Support Transparent Command operation②;
● Support addressable multiple antenna ports;
● Support DPPM/WPPM tag-parsing mode③;
● Support reader network;
● Low power dissipation design;
● Provide DLL and Demonstration Software Source code to facilitate further development.
*Effective distance depends on RF output power, antenna, tag and working environment.
①Scan-mode: It refers to reader’s automatic working mode.
②Transparent Command Operation: It is an advanced feature designed to support tag’s future functions and different chip vendors’customized tag functions.
③DPPM/WPPM Tag-parsing Mode: DPPM tag-parsing mode means depth-first parsing pattern and WPPM means breadth-first parsing
pattern. They are different methods of decoding multiple tags.
