UHF RFID Reader Module
HYM740
(V2.0)
HYM740 UHF RFID reader module uses R2000 chip, which complies with EPC
C1G2 protocol, its working frequency is 840~960MHz，with LBT function. It
supports dense reader working mode（DRM）。With standard 12dBi antenna，the
reading distance can reach 24 meters, maximum identifying speed can reach 400/S;
with simple power supply and interface circuit, a high-performance RFID system can
be established. It is suitable for logistics, costume, medical industry, and complexassets management, etc.
