ZKTeco D3 Face and Biometric Time Attendance Device

ZKTeco D3 Face and Biometric Time Attendance Device — Face Recognition Attendance & Access Device

For HR teams tired of buddy-punching and ghost attendance, the ZKTeco D3 Face and Biometric Time Attendance Device is a clean upgrade. Specifically, AI face recognition with liveness detection makes proxy attendance effectively impossible — and the device pairs with eTimeTrackLite, ZKBio CVSecurity and most popular HRMS platforms.

Why integrators specify the D3 Face and Biometric Time Attendance Device

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

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

⚡ Sub-second recognition — verification completes in under a second, so peak-hour queues at shift change essentially vanish.

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

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

🤳 Contactless & hygienic — no touching anything. Notably, this has been a popular post-pandemic upgrade for hospitals, food units and shared office spaces.

Frequently asked questions

Q. How accurate is the face recognition on the D3 Face and 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. Can the device work without an internet connection?
Absolutely. All face templates and transaction logs live on the device's local storage. As a result, a brief network outage never blocks employees from entering. Internet is only needed when syncing to eTimeTrackLite, ZKBio CVSecurity or a cloud server.

Q. Can it control my existing door lock?
Yes. The D3 Face and 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 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.
