General Description:
It is a high performance UHF Access Control Attendance Reader. It is designed upon fully self-intellectual property. Based on proprietary efficient digital signal processing algorithm, it supports fast tag read/write operation with high identification rate. It can be widely applied in many RFID application systems such as access control, attendance system, elevator control and industrial production process control system.
Features:
1. Self-intellectual property;
2. Support ISO18000-6C (EPC C1G2) protocol tag;
3. 865~868MHz, 902~928MHz frequency band (frequency customization optional by Soft);
4. FHSS or Fix Frequency transmission;
5. RF output power up to 17dBm (adjustable);
6. 3dBi Circular Ceramic Antenna with effect distance up to 0~50cm *;
7. Support active mode, answer mode;
8. Support RS232, RS485, Wiegand, Trigger.
9. Support read TID, and TID cannot be copied.
* Effective distance depends on antenna, tag and environment.
