RFID Reader Module
- 2 -
Brief introduction
HYM7
4
0 UHF RFID reader uses R2000 chip, which complies with EPC C1G2
protocol, its working frequency is 902~928MHz
，
with LBT function. It supports dense
reader working mode
（
DRM
）
。
With standard 7dBi 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, apparel, medical industry, and complex assets management, etc.
