ZKTeco K40 is a fingerprint-based time attendance and simple access control terminal designed to make employee tracking easier and more accurate than manual registers. With a 2.8‑inch TFT colour screen and user‑friendly interface, staff and admins can clearly see attendance status, menus, and notifications. The device is widely used in corporate offices, coaching centres, factories, showrooms, and educational institutions across Bangladesh because it offers strong performance at an affordable price point. For many businesses, K40 is a practical entry into biometric time attendance automation.
Key features of ZKTeco K40
Large capacity for growing teams
K40 typically supports up to 3,000 fingerprint templates and up to 3,000 ID cards, with transaction log capacity around 80,000–100,000 records depending on firmware. This makes it suitable for both small and moderately large workforces without frequent log clearing.
Multiple verification methods
Users can verify using a fingerprint, ID card (optional), or numeric password, allowing flexible combinations for different security levels. This also helps when a fingerprint is difficult to read due to dust or minor injuries.
2.8″ TFT color display and easy UI
The 2.8‑inch TFT screen shows names, IDs, time, and menu icons clearly, making daily use simple even for first‑time users. The interface supports features like T9 input, self‑service query, and automatic status switching (in, out, break, etc.).
Connectivity and data management
K40 comes with TCP/IP network connectivity and a USB host, so you can either connect it directly to your LAN or download/upload data via USB drive. This makes integrating with attendance software and generating payroll reports much easier.
Built‑in battery backup
One of the most important benefits for Bangladeshi users is the built‑in backup battery, which can keep the device running for several hours during power outages. This ensures attendance logs are not missed when electricity drops unexpectedly.
Simple access control and schedule bell
The K40 can connect to a third‑party electric lock and exit button for basic door control, as well as schedule bells for shift start/end alerts. For many small offices, this is enough to control entry without investing in a full access control panel.
