ZKTeco SA40B-E RFID Keypad Biometric Time Attendance Device

ZKTeco SA40B-E RFID Keypad Biometric Time Attendance Device — Face Recognition Attendance & Access Device

Built for offices, factories, schools and hospitals, the ZKTeco SA40B-E RFID Keypad Biometric Time Attendance Device turns biometric attendance into a 2-second walk-through experience. Plus, with multiple verification modes (face, card, PIN), you can layer security exactly the way each entrance demands.

Why integrators specify the SA40B-E RFID Keypad 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.

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

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

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

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

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

Frequently asked questions

Q. Can it control my existing door lock?
Yes. The SA40B-E RFID Keypad 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. Is the data hosted in India?
Yes. When paired with our India-hosted ZKBio cloud option, all biometric and attendance data stays within Indian data centers. Consequently, compliance, privacy and local support stay simple.

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 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.
