ZKTeco SFace900+ID Biometric Time Attendance Device

ZKTeco SFace900+ID Biometric Time Attendance Device — Face Recognition Attendance & Access Device

For HR teams tired of buddy-punching and ghost attendance, the ZKTeco SFace900+ID 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 SFace900+ID Biometric Time Attendance Device

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

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

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

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

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

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

Where this fits best

Healthcare campuses · Factories & manufacturing plants · Construction sites · Government departments · Corporate offices · Hotels & hospitality · Hospitals & clinics

Frequently asked questions

Q. Can it control my existing door lock?
Yes. The SFace900+ID 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. 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. Does the SFace900+ID Biometric Time Attendance Device work in low light?
Yes — the WDR camera handles dim lobbies, and an adjustable LED fill light kicks in automatically when ambient light drops. Therefore, deployments in basements, corridors and shift-change areas stay reliable around the clock.

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.
