12 ports UHF RFID Reader Module

Products Mode: HYM781

HYM781 UHF RFID reader uses R2000 chip, which complies with EPC C1G2 protocol, its working frequency is 840~960MHz. It supports dense reader working mode.With standard 8dBi antenna,the reading distance can  reach up to 10meters, 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 new-retail, file management, logistics,
costume, medical industry,garment Industry and complex assets managements etc.
