ZKTeco K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device

ZKTeco K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device — Face Recognition Attendance & Access Device

The ZKTeco K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device brings AI-powered face recognition to everyday attendance and access control in India. Notably, recognition completes in well under a second, and the device works fully offline — so a network outage never blocks your staff from entering the building.

Why integrators specify the K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device

📚 Massive on-device capacity — thousands of face templates and transaction records live locally. Furthermore, a brief network outage never blocks entry.

🛡️ Live anti-spoofing — printed photos, video replays and 3D masks are rejected automatically. As a result, proxy attendance is effectively impossible.

🌡️ Low-light camera — WDR sensor with adjustable LED fill light handles dim corridors and basement entries reliably.

📊 Auto-export to payroll — pairs with eTimeTrackLite, ZKBio CVSecurity and most HRMS platforms. Therefore, monthly attendance closing takes minutes, not days.

🔌 Pairs with existing infrastructure — Wiegand, RS-485 and TCP/IP outputs hook into the access-control panels and HRMS you already use.

📏 Extended recognition range — registers faces from up to 2 m away, so employees walk past without breaking stride.

Frequently asked questions

Q. How many users does it really support?
On-device capacity is several thousand face templates plus matching card credentials. Additionally, multiple units can be chained across sites and consolidated centrally — so total user count scales effectively without limit.

Q. Can it control my existing door lock?
Yes. The K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device connects to third-party electric locks, door sensors, exit buttons and alarm outputs directly. Plus, Wiegand input/output makes it a drop-in replacement for older card readers on legacy access-control panels.

Q. How accurate is the face recognition on the K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device?
Recognition completes in under a second with a low false-acceptance rate thanks to ZKTeco's visible-light algorithm. Moreover, live anti-spoofing rejects printed photos, video replays and 3D masks. In real-world office deployments, customers typically see >99% accuracy after a clean enrolment.

Q. What integrations are supported for payroll and HRMS?
The K40 Pro+WiFi Fingerprint Terminal Biometric Time Attendance Device integrates natively with eTimeTrackLite, ZKBio CVSecurity, BioTime and most third-party HRMS platforms. Furthermore, attendance data exports cleanly to Excel, CSV and standard payroll formats.
