The system alarms only with half signal, which avoids the interference of other radio wave efficiently. The tag/label has many advantages such as light weight, small volume, cheap price, stable capability, high detecting rate, good anti-interference and less misreport. There are two kinds and they are standing type and cover-up type. It’s an ideal system for clothing shops.
