ZKTeco SenseFace M2F-LR Facial and Fingerprint Time & Attendance Terminal

If you run a small or medium-sized business and need a reliable way to track employee attendance while also controlling access to your premises, the ZKTeco SenseFace M2F-LR delivers a complete solution in a single device. It combines visible-light facial authentication, an optical fingerprint sensor, RFID card support, and a password keypad — offering high performance at a price point built for SMEs.

Product Overview

The SenseFace M2F-LR is a time and attendance terminal with access control support from ZKTeco, designed to simplify workforce management and record working hours accurately without added complexity. The device is built on Visible Light Facial Authentication technology with anti-spoofing protection, paired with a ZK optical fingerprint sensor. This gives you the flexibility to choose whichever verification method suits your team best — face, fingerprint, RFID card, or a password entered on the 16-key physical keypad.

The terminal runs on a Linux operating system powered by a dual-core 1GHz processor, with 512MB RAM and 8GB ROM, ensuring fast response times even with larger user databases. Fingerprint recognition takes less than one second, and facial recognition takes less than 1.2 seconds, with very low false acceptance rates (FAR ≤ 0.02% for face and ≤ 0.0001% for fingerprint). In practice, that means fast, accurate check-ins with no bottlenecks at the entrance during morning rush hour.

On the connectivity side, the device supports TCP/IP and Wi-Fi (IEEE802.11b/g/n/ax, 2.4GHz), so it can be wired or wirelessly connected depending on your site's infrastructure. It also includes outputs for an electric lock, a door sensor, and an exit button, functioning as a full access control unit rather than just an attendance clock. To keep working through power outages, an 2,000mAh backup battery provides up to 4 hours of continuous operation or 7 hours on standby, and fully recharges in 5 hours.

Why Choose the ZKTeco SenseFace M2F-LR?

• Visible-light facial authentication with anti-spoofing: The terminal distinguishes a real face from a printed photo or a phone screen, preventing buddy-punching and fraudulent check-ins.
• Multiple authentication methods: Face, fingerprint, RFID card, and password — each employee can use whichever method works best for them, and the system keeps running even if one method is temporarily unavailable (e.g. a bandaged finger).
• Fast recognition speed: Under 1 second for fingerprint and under 1.2 seconds for face, avoiding queues at the entrance during peak clock-in and clock-out times.
• Capacity built for SMEs: Supports up to 1,000 users, 1,000 fingerprints, 500 faces, and 150,000 stored attendance transactions — enough for a mid-sized team without frequent data resets.
• Flexible connectivity: TCP/IP, Wi-Fi, and a USB port for data export via flash drive make installation straightforward regardless of whether wired networking is available on site.
• Uninterrupted operation during power cuts: The backup battery keeps the terminal running for up to 4 hours, so attendance tracking doesn't stop when the power does.
• Cloud or on-premise management, your choice: Works with the ZKBio Zlink cloud app and web portal for remote management from a phone or browser, or with the on-premise ZKBio Time software for businesses that prefer to host their data locally.

Who Is This Terminal For?

The SenseFace M2F-LR suits small and medium businesses that need accurate time and attendance tracking tied to access control — offices and service companies, factories and production lines that need to clock in a large workforce quickly at shift changes, clinics and medical centers, multi-branch retail businesses that want centralized attendance management through the ZKBio Zlink app, and any organization looking to replace manual sign-in sheets or older fingerprint-only devices with a more tamper-resistant solution.
