Features: More convenient: Directly implant software into the fingerprint time attendance with complex algorithm, eliminating the pain of using a complex attendance software. More simple: 5 minutes to learn operation, super easy operation process, three-step usage, you can export specific EXCEL format attendance report only with a U disk. Faster: High-standard fuzzy recognition algorithm, attendance speed is less than one second, employee attendance can be quickly accomplished. More precise: High-precision optical total reflection fingerprint entry device, strong resistance to scratch and wear, no biased recognition with automatically updated recognition algorithm. Wider application: Suitable for the entrances and exits of office, factory, hotel, school, etc. Specification: Condition: Brand New Material: PVC Fingerprint Capacity: 1000 Recording Capacity: 100000 Operating Method: Off-line Recognition Method: Fingerprint, password Recognition Ratio: 1:N, 1:1 Recognition Speed: ≤1.5s FAR: ≤0.0001% FRR: ≤0.01% Communication Method: U disk ( USB ), free of software Scanner: High precision total reflection optics scanner Effective Scanning Range: 16*16mm(360°recognition) LCD: 2.4in high-definition color LCD screen Language: English Fingerprint Image Resolution: 500DPI Operating Temperature: 0°C-60°C Operating Humidity: 20%-60% Size: Approx.170*120*31mm/6.7*4.7*1.2in Package weight: Approx.439g/15.5oz Package List: 1 * Fingerprint Time Attendance 1 * Screw Bag 1 * User Manual .
