We find the Biometric Employee Attendance Machine UFace402 Biometric Fingerprint Face Facial Recognition Time Attendance TCP/IP Door Access Control System With Free Software for Smal,Uface402-battery-English to be a compact, multifunctional unit designed for workplaces that need reliable time-and-attendance tracking and simple door access control. We appreciate that it combines facial recognition and fingerprint sensors in a single unit and is packaged with free software to manage users and logs.

What this device promises

We see that the UFace402 supports both fingerprint and facial templates, network connectivity via TCP/IP, an optional built-in battery backup, and multi-language support. We like that it aims at small to medium-sized businesses that want an integrated attendance and door control solution without complicated third-party systems.

Key Specifications

We will summarize the most important technical specifications so that we can quickly check if the device fits our needs. The following table breaks down core features and capacity so we can compare at a glance.

We think that having this at-a-glance summary helps us decide whether the UFace402 meets our basic capacity and connectivity requirements.

Design and Build

We find the device to be compact and designed for wall mounting near entrances or in corridors where employees pass frequently. The front panel typically houses a camera for face recognition, a fingerprint sensor, and a small screen or keypad for interaction.

We appreciate a balance of plastic and metal components that keeps the device lightweight while still feeling sturdy enough for daily use. The optional internal battery makes the unit slightly thicker but adds resilience during short power outages.

Screen and Controls

The user interface usually includes a color screen with menu navigation and possibly physical buttons or a touchscreen depending on the specific variant we purchase. We like a clear, responsive screen because it helps users enroll and verify quickly without confusion.

We also value simple icons and multi-language prompts to reduce training time for staff who might not be comfortable with complex menus or English-only interfaces.

Enrollment and Setup

We find the enrollment process for both facial and fingerprint templates reasonably straightforward when using the included software or on-device menus. Typically, we enroll users by capturing their face and fingerprints, assigning user IDs, and configuring access permissions if the door control function is in use.

We recommend preparing a spreadsheet or list of employees with their user IDs to import via the software (if supported), which saves time when enrolling large teams. If we manually enroll on the device, checking ambient lighting and fingerprint cleanliness improves registration quality.

Software-assisted Enrollment

We like that free software is included because it usually provides bulk import, template management, user grouping, and attendance report generation. In our experience, connecting the device to a local network and importing user templates is faster than registering every employee on the device itself.

We also find that configuring synchronization intervals and backup schedules through the software helps keep attendance logs centralized.

Performance: Face Recognition

We notice that the UFace402 claims support for up to 3,000 face templates and high verification speed, which is suitable for small to mid-size offices. The recognition speed is generally quick, and the device usually authenticates a registered face in under a second under good lighting.

We should be mindful that face recognition performance depends on camera quality and ambient light; devices perform best when users face the camera at a reasonable distance and angle. For environments with variable lighting, we recommend placing the device where light is consistent and avoiding strong backlighting.

Face Template Quality and Limits

We like that the device supports a relatively high number of face templates, enabling larger staff lists without frequent purging. However, we should enroll several facial angles and expressions for each user where possible to improve recognition accuracy across different appearances.

We also note that accessories like masks, hats, or sunglasses can degrade recognition accuracy; in those scenarios, the fingerprint verification acts as a robust fallback.

Performance: Fingerprint Recognition

We observe that supporting up to 4,000 fingerprint templates makes the UFace402 well-suited for many small businesses. Fingerprint verification is reliable when fingerprints are clean, and the sensor is maintained.

We find fingerprint authentication especially useful when facial recognition is impeded—such as by face coverings or in poor lighting—offering a practical secondary verification mode.

Fingerprint Sensor Tips

We recommend enrolling multiple fingers per user (typically two or three) to reduce false rejections caused by cuts, dry skin, or worn fingerprints. Keeping the sensor clean and dry helps preserve accurate reads and reduces enrollment and verification problems.

We also note that enrolling a fingerprint requires consistent pressure and correct finger placement for optimal template creation.

Speed and Accuracy

We feel that the device’s advertised “high verification speed” is generally accurate in typical office conditions, delivering fast recognition times for both face and fingerprint modes. Accuracy is satisfactory when proper enrollment practices are followed and environmental conditions are reasonable.

We should account for occasional false accepts or rejects in any biometric system, and using multi-factor authentication (face + PIN or fingerprint + PIN) may be appropriate for higher security needs.

Factors That Affect Speed and Accuracy

We understand that ambient light, camera angle, fingerprint condition, and device placement influence both speed and accuracy. Regularly updating templates when significant appearance changes occur (haircuts, new glasses) keeps recognition performance strong.

We also suggest testing the device with real users before full deployment to identify situational issues and fine-tune placement and settings.

Battery Backup and Power

We like that the UFace402 offers an optional built-in battery backup that provides approximately four hours of continuous operation. That battery support helps ensure attendance logging and door control continue through short blackouts or power interruptions.

We recommend enabling the battery for locations where power fluctuations are common, and ensuring the device is fully charged and tested periodically to verify backup performance.

Installing and Maintaining the Battery

We advise verifying whether the specific unit we purchase includes the battery or whether it’s an optional add-on, then following the manufacturer’s guidelines for charging and replacement. Periodic battery health checks and avoiding deep discharge will extend the battery life.

We also caution that batteries age; after a few years, capacity will drop, so scheduling routine checks is sensible for mission-critical installations.

Software and Integration

We appreciate the inclusion of free software with the UFace402, as it typically enables attendance report generation, user management, template import/export, and time synchronization. The software often supports common formats like Excel and can integrate with payroll systems when configured properly.

We recommend checking the software’s compatibility with our current operating systems and network setup, since some attendance packages are Windows-based and might require specific network permissions.

Features to Expect from the Included Software

We expect features like clock-in/out logs, shift scheduling, report customization, and user grouping in the bundled software. Ease of use and straightforward export options make payroll reconciliation simpler for our HR or admin teams.

We also like that some software versions offer remote device management, which helps when administering multiple units across different entrances or facilities.

Network and Access Control

We value that the device supports TCP/IP connectivity, making it easy to integrate into an existing Ethernet network for remote management and log collection. For door access functions, the unit usually provides relay outputs and auxiliary I/O to control locks, alarms, or exit buttons.

We recommend placing the device on a secure, segmented network or VLAN to limit exposure and reduce the attack surface if our organization has network security policies.

Configuring Network Settings

We find that setting a static IP, configuring firewall rules, and enabling secure network policies are key steps to ensure reliable communications with the attendance server. Where possible, we also suggest configuring encrypted channels or limiting device accessibility to trusted hosts.

If the device offers additional interfaces like RS232/485 or Wi-Fi (depending on model), we should confirm compatibility and security settings before enabling them.

User Interface and Usability

We like a friendly, intuitive interface that reduces training time and errors for employees. The UFace402’s advanced UI claims to be user-friendly, which helps new users enroll and perform verification without extensive guidance.

We recommend customizing welcome prompts and language settings to match our workforce and avoid confusion during clock-in/out operations.

Multi-language Support

We appreciate the multi-language support in this device because it helps organizations with multilingual employees. Setting default language per user or a device-wide language will make interaction smoother for our teams.

We also note that some translations in less-common languages can be imperfect, so we should review prompts during setup to ensure clarity.

Installation and Mounting

We find installing the UFace402 straightforward for teams comfortable with basic electrical and network work; wall mounting near main entrances is common. It’s important to mount at eye level and allow enough clearance for users to stand comfortably at the camera and fingerprint sensor.

We recommend checking the wiring diagram for relays, exit buttons, and power supply, and securing any exposed cables to prevent tampering or accidental disconnection.

Professional vs. DIY Installation

We believe that a professional installer can speed up setup if we plan to integrate with access-controlled doors, strikes, or maglocks. For simple attendance-only deployments, our in-house IT or facilities staff can typically handle mounting and network configuration.

Still, we suggest testing the entire flow—enrollment, verification, and report retrieval—before finalizing installation.

Security and Data Privacy

We take biometric security and user privacy seriously, and we like that the UFace402 uses biometric templates rather than storing raw images in most configurations. Templates are generally encrypted and used only for local verification unless explicitly exported or backed up.

We advise reviewing local laws and regulations about biometric data storage and informing employees about the system, its purpose, and our retention policy to remain compliant with privacy guidelines.

Data Retention and Access Control

We recommend setting policies for how long logs are kept, who can access them, and how templates are backed up. The software’s user-role settings help ensure only authorized administrators can export or modify biometrics and attendance records.

Regular audits and secure backups protect against accidental or malicious loss while maintaining transparent retention practices for HR.

Capacity and Scalability

We like that the UFace402 supports 3,000 face templates and 4,000 fingerprint templates, which suits many small and some mid-sized organizations. If we expect rapid growth beyond those numbers, planning for multiple devices or a higher-capacity model is prudent.

We also appreciate that networked units can be managed centrally to scale across multiple entrances or sites.

Scaling Across Multiple Sites

We often deploy multiple UFace402 units and use the central software to consolidate logs and manage users across locations. Ensuring consistent configuration and synchronized time settings helps maintain accurate attendance reporting across sites.

If we plan significant scaling, evaluating models with larger template capacities or server-based recognition options may be worthwhile.

Maintenance and Support

We value devices that are low-maintenance, and routine upkeep for the UFace402 generally involves cleaning the fingerprint sensor, keeping the camera lens dust-free, and updating software/firmware as released. Periodic checks of battery health and relay functionality prevent service interruptions.

We recommend registering the device with the vendor or store where we purchased it to access warranty and support services, and keeping firmware up to date to benefit from bug fixes and feature improvements.

Troubleshooting Support

We find that the included manual and vendor support are the first lines of support for common issues like network connection problems, failed enrollments, or device hangs. If local support is limited, community forums and manuals can be helpful while waiting for vendor response.

Documenting common fixes internally helps our team respond faster to recurring problems.
