HYM350 is Phychip single port low cost UHF reader module.
It is cost effective UHF reader module, suitable for developing short read range UHF reader, like USB reader, portable reader and other smart reading devices, etc.
HYM350 UHF RFID reader complies with EPC C1G2 protocol, its working frequency is 840~960MHz. With standard 8dBi antenna, the reading distance can reach 0.8 meter; with simple power supply and interface circuit, a low-cost RFID system can be established. It is suitable for entrance guarding, medical wrist band, retrospective food safety system, anti-counterfeiting, etc., especially suitable for mini UHF RFID handsets or portable set.
