The ZKTeco ZK40 Biometric Time Attendance Terminal offers an efficient and secure solution for tracking employee attendance with the latest in fingerprint recognition technology. Designed for small to mid-sized businesses, this terminal simplifies workforce management by replacing outdated manual systems with a smart, automated time-tracking method.
With support for fingerprint, RFID cards, and PIN codes, the ZK40 makes clock-ins and clock-outs fast, accurate, and tamper-proof. It reduces buddy punching, prevents time fraud, and provides accurate logs that are easy to export and integrate with payroll systems.
Whether you’re managing a retail store, office, factory, or school, the ZK40 is an affordable and reliable biometric time attendance solution that boosts productivity and ensures accurate employee data collection.
Fast & Accurate Fingerprint Recognition
The ZK40 uses ZKTeco’s advanced fingerprint algorithm to provide high-speed identification, even for users with wet, dry, or rough fingerprints. The device supports up to 1,000 fingerprint templates and can store 100,000 attendance logs, making it suitable for small and medium-sized teams.
Fingerprint recognition ensures only authorized personnel can clock in or out, eliminating time theft and buddy punching. Clocking in takes less than a second, keeping queues short and operations smooth.
Multiple Verification Modes
The ZK40 supports three verification methods:
-
Fingerprint
-
RFID card
-
PIN code
Users can choose a single method or a combination (e.g., Fingerprint + PIN) for higher security. This flexibility makes it easy to adapt to different work environments and user preferences.
It’s ideal for businesses that need to manage access across different departments or shifts with varying access rules.
User-Friendly Interface & LCD Display
Equipped with a 2.8-inch TFT color display, the ZK40 offers an intuitive and easy-to-navigate interface. Employees can quickly see their punch status, messages, or error prompts in real time.
The on-screen menus and keypad make it easy to register new users, configure settings, and manage attendance logs directly from the device—no need for a PC to perform basic tasks.
The built-in buzzer and status icons provide instant feedback upon successful or failed entries, making operation simple even for first-time users.
Flexible Connectivity Options
The ZK40 can communicate with your system through:
-
USB flash drive (data download/upload)
-
TCP/IP (Ethernet LAN connection)
This makes it easy to transfer attendance data to your computer or network. With TCP/IP, you can remotely manage attendance records, view logs, and update firmware via PC-based attendance management software.
USB support also allows for offline data transfer, perfect for standalone use in environments without network connectivity.
Compatible ZKTeco software like ZKTime.Net 3.0 enables complete report generation, shift management, user tracking, and even payroll integration with third-party tools.
Compact Design with Efficient Performance
The ZK40’s sleek and compact design allows it to be mounted anywhere—on walls, doorways, or reception desks. Its energy-efficient components ensure low power consumption, even when running 24/7.
Built for durability, it performs well in busy environments like:
-
Offices and coworking spaces
-
Retail outlets and warehouses
-
Educational institutions
-
Small factories and workshops
You get reliable biometric security and accurate attendance tracking with minimal setup and maintenance required.
