Brief introduction
HYM750 UHF RFID reader module uses R2000 chip, which complies with ISO18000-6C protocol, with LBT function(Customizable).It supports dense reader working mode(DRM）. With standard 8 dBi antenna，the reading distance can reach up to 10 meters, maximum identifying speed can reach up to 400/S; with simple power supply and interface circuit, a high-performance RFID system can be established. It is suitable for logistics, apparel, medical industry, and complex assets management, etc.
