The ZKTeco K40 is a compact and budget-friendly biometric terminal designed to make employee attendance tracking simple and accurate. It uses a high-speed fingerprint sensor that verifies identity in under 0.5 seconds, eliminating time theft and buddy punching.
The 2.8-inch TFT color display offers a clear, easy-to-use interface for both employees and administrators. It supports up to 3,000 fingerprint users and stores up to 100,000 transaction records, making it well suited for small to medium-sized organizations.
Connecting it to your office network is easy via TCP/IP, and data can also be transferred through a USB drive for locations without network access. A built-in 2,000mAh battery keeps the device running for up to 4 hours during power interruptions.
It also supports basic door access control, with interfaces for third-party electric locks and exit buttons, making it a versatile solution for both attendance and security needs.
