Brief Introduction
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 complex assets management, etc.
