Features: 4inch high-definition large screen, simple structure design, T9 input method, directly edit the personnel department, shifts, etc. on the attendance machine, easy to operate. No need for software, more convenient: through the complex algorithm, the software is directly implanted into the fingerprint attendance machine, eliminating the pain of using complex attendance software. Simpler: 5 minutes to learn the operation, three steps can be used, only need to use the U disk to export the detailed EXCEL format attendance report. Faster: High-standard fuzzy recognition algorithm, attendance speed is less than one second, employee attendance is not queued. More accurate: high-precision optical total reflection fingerprint head, scratch-resistant and wear-resistant, with automatic update recognition algorithm to identify no deviation. The live voice prompts, and the timed ringing after work, each time the fingerprint is pressed, there will be a voice prompt to punch the card successfully. With TCP/IP network interface, you can connect to the network to view attendance data in real time.
