Understanding and Working with ZKTeco Data Files: A Guide to ZKTeco Data File Readers

ZKTeco is a well-known brand in the biometric security solutions industry, providing a range of products such as fingerprint and facial recognition systems. These systems generate data files that need to be read, processed, and analyzed for various purposes, including access control, time attendance, and security monitoring. In this article, we will explore the concept of ZKTeco data files and the tools required to read them, focusing on ZKTeco data file readers. zkteco dat file reader

1. Objective

This report provides a comprehensive guide to understanding, reading, and extracting data from ZKTeco DAT files. These files store attendance logs, user information, and device settings from ZKTeco biometric devices (fingerprint, face recognition, RFID). A custom reader is often required because the DAT format is proprietary and not directly readable by standard software. Understanding and Working with ZKTeco Data Files: A

2. Background

ZKTeco devices (e.g., K40, K80, SF1000, T6 series) export data in .dat files for: These files are typically generated via:

  • Attendance logs (check-in/out times)
  • User information (name, ID, password, privilege level)
  • Device settings (time, network config, algorithm version)
  • Fingerprint templates (encrypted)

These files are typically generated via:

  • USB export from the device
  • ZKTeco software (Attlog, ZKAccess, BioTime)
  • SDK or direct TCP/UDP communication

What’s inside a ZKTeco DAT file?

A DAT file from ZKTeco is generally a compact binary container holding one or more of the following:

  • Attendance records (timestamps, user IDs, device ID)
  • User templates (fingerprint minutiae, template format version)
  • Device settings or logs The exact structure depends on device model and firmware version. That’s why readers either rely on reverse-engineered formats or use official device protocols to extract human-readable content.

Overview — ZKTeco DAT File Reader

ZKTeco DAT file reader is a software tool (or component within third‑party utilities) used to parse and extract attendance, timestamp, and configuration data from .DAT files produced by ZKTeco biometric devices (fingerprint, face, RFID time clocks). These DAT files store raw device exports or backups and are commonly used for offline transfer, backup, or integration with payroll and HR systems.

A. Official Software (Simplest)

  • ZKTeco Attlog (free utility) – imports .dat and exports CSV.
  • BioTime / ZKBioSecurity – full database management.
  • ZKAccess 3.5 – for access control logs.
