We find the Biometric Employee Attendance Machine 800 Iface800TCP/IP Biometric Fingerprint Face Facial Time Attendance Door Access Control Time Clock Time Recorder System for Small B,Uface800 N Id-One Size to be a compact, multi-biometric terminal aimed at small- to medium-sized businesses. It combines facial recognition and fingerprint scanning with a touch interface and multiple connectivity options, and its core platform and algorithm are designed by ZK — a familiar name in biometric access control.

What the product promises

This terminal promises fast, accurate biometric identification using ZK’s latest ZEM800 platform and ZK Face 7.0 algorithm, which are intended to improve recognition reliability. It also includes a high-definition infrared camera for low-light or dark environments, a capacious memory and a touchscreen interface to simplify daily operations.

What’s in the box

We expect the package to include the main terminal unit, a power cable or power adapter, a mounting bracket or screws, a quick start guide, and possibly a USB drive or CD with device software and user manuals. Optional accessories like Wi-Fi or GPRS modules might be separate purchases depending on the seller.

Key specifications

We want a clear snapshot of the technical specs before we make decisions, so we’ve summarized the important details in the table below for easier comparison. This helps us quickly see what hardware and features the unit brings to the table.

Design and build quality

We appreciate devices that feel solid and professional, and this terminal gives a reasonably robust impression for its category. The casing is typically plastic, but the build is designed for daily use in office or reception environments and should withstand typical interactions.

Physical dimensions and mounting

The machine is compact enough to mount on a wall near an entryway or attach to a reception desk without dominating the space. We can expect standard mounting points and a form factor that balances visibility and unobtrusiveness.

Touchscreen and user interface

All operations on the device are intended to be handled through the 4.3-inch TFT touch screen, which gives us a visual and interactive way to enroll users and review logs. The screen size is large enough for clear menus and simple navigation, though power users may want a companion desktop application for advanced reporting.

Biometric systems

We prefer solutions that offer more than one biometric modality, because redundancy improves reliability and user convenience. This device supports both face and fingerprint recognition, and the combination is particularly useful for environments where one modality might be less effective for some users.

Face recognition performance

Using the ZK Face 7.0 algorithm and the high-definition infrared camera, face recognition is designed to work in a wide range of lighting conditions, including dim environments. In practice, we generally see faster recognition when users look directly at the device and when enrollment is done with a few varied captures to account for different angles and expressions.

Fingerprint recognition performance

Fingerprint recognition is handled by the integrated scanner and the 630 MHz multi-bio processor, giving a good balance of speed and accuracy for most users. We find fingerprints are very reliable for individuals with clear fingerprints, but users with worn or damaged fingerprints may need alternative verification methods.

Multi-biometric accuracy and scenarios

When we combine face and fingerprint modalities, false acceptance and false rejection rates typically improve, because the system can cross-validate or require both methods for high-security contexts. This also helps with user convenience — if a fingerprint is unreadable, the face can serve as backup, and vice versa.

Hardware and performance

We value hardware that matches the software claims, and the Iface800 uses a 630 MHz ZK Multi-Bio processor which is intended to handle biometric templates and recognition tasks smoothly. Large-capacity memory supports storing user templates and attendance logs without frequent archiving.

Processor and memory

The processor is a dedicated biometric-grade chip that runs the recognition algorithms and the user interface; it’s optimized for responsiveness. Memory capacity is described as large, and it should be sufficient for small businesses that enroll hundreds to a few thousand users, though exact supported user/template numbers should be confirmed with the seller.

Camera and sensors

A high-definition infrared camera gives the unit a real advantage for face recognition under poor lighting or in darker corridors. Infrared illumination reduces the impact of shadows and makes facial acquisition more consistent across different workplace lighting setups.

Connectivity and power

We like devices with multiple connectivity options because they adapt to different network setups and backup plans. This terminal supports RS232/485 and TCP/IP out of the box, and offers optional Wi-Fi or GPRS for locations without wired network access.

Network options: RS232/485, TCP/IP, Wi-Fi, GPRS

Wired TCP/IP communication is the most reliable for central logging and real-time data transfer, while RS232/485 can be useful for integration with specific door controllers or legacy systems. The availability of optional Wi-Fi or GPRS adds flexibility for remote sites or situations where cabling is impractical, and it gives us options when setting up multiple distributed terminals.

Power: Built-in battery backup

The built-in 2000 mAh battery is a practical feature because it protects against data loss or service interruption during short power outages. For locations with unstable power, this backup helps ensure that employees can still clock in and out and that the device will transmit or store data until power is restored.

Installation and setup

We want setup to be straightforward, and this machine’s touchscreen-based interface combined with common networking protocols generally makes initial installation manageable for IT staff. The vendor documentation and on-screen prompts should guide basic configuration tasks.

Enrollment process

User enrollment typically involves capturing a face image and at least one fingerprint sample, plus assigning user IDs and access permissions. We recommend enrolling multiple facial angles and fingerprint impressions per user to improve recognition success rates in daily use.

Mounting and network configuration

Mounting is usually a simple matter of wall-anchoring the bracket and attaching the terminal at eye level for comfortable facial capture. For networking, connecting via TCP/IP is best practice for central management; static or DHCP addressing can be configured through the device’s touchscreen menus.

Software and integration

We prefer devices that can integrate seamlessly with attendance and payroll software, and ZK devices generally provide either bundled software or APIs for integration. Monitoring, reporting, and exporting attendance logs should be possible either through bundled desktop software or cloud solutions depending on the model and seller.

Attendance features and reporting

Core time attendance features include time stamping, shift and schedule management, overtime calculations, and basic reporting for payroll. We can typically generate reports by user, by date range, and by department, which helps when reconciling hours for payroll or compliance.

Integration with third-party systems

Many ZK-based terminals support middleware or SDKs that enable integration with third-party HR and payroll systems, which reduces manual data entry. If we need custom integrations, developers can use available APIs or SDKs, but we should confirm compatibility with our specific HR software before purchasing.

Security and privacy

We take biometric data protection seriously, and this device stores templates rather than raw biometric images, which is a standard practice to protect sensitive data. Still, we need to ensure secure transmission (use encryption where possible) and follow local regulations on biometric data storage and consent.

Data storage and encryption

The device’s memory is used to store biometric templates and attendance logs, and it is important to clarify whether template storage is encrypted and whether network transmissions can be secured via VPN or TLS. We should ask the vendor for specifics about encryption at rest and in transit.

User consent and legal compliance

Before deployment, we need to obtain informed consent from employees and ensure our usage complies with regional privacy laws and workplace regulations. Documenting policies for retention and deletion of biometric data is a responsible step and often a legal necessity.

Use cases and environments

We see this terminal as a fit for offices, small factories, clinics, or schools where a compact, easy-to-manage attendance and access system is desirable. It’s particularly useful in environments where lighting conditions vary, since the infrared camera helps maintain facial recognition performance.

Small business setups

For small businesses, the Iface800 provides a balanced combination of features without the complexity and cost of enterprise-grade systems. The onboard battery and TCP/IP support make it flexible for locations with limited infrastructure.

Medium or multi-site deployments

If we manage multiple locations, the optional Wi-Fi/GPRS and RS232/485 compatibility can reduce integration friction, but we will want centralized software and clear processes for syncing attendance data. For larger deployments we may still look for higher-capacity or cloud-native options depending on scale.

Maintenance and troubleshooting

Routine maintenance is minimal and generally includes cleaning the fingerprint sensor and camera area, ensuring firmware stays current, and periodically backing up logs. Troubleshooting tends to be straightforward, centering on network connectivity, enrollment issues, or sensor cleanliness.

Routine upkeep

Regularly wiping the scanner and camera with a soft, lint-free cloth keeps captures reliable, and checking for firmware updates helps maintain security and performance. We should also schedule backups of attendance data and document any local data retention policies.

Common troubleshooting steps

If recognition fails, we first clean the sensor and camera, then re-enroll the user with multiple samples. Network issues are often resolved by checking cables, verifying IP settings and confirming the server or software endpoints are reachable.
