Ensure encryption is configured correctly, though most modern devices default to this 1.2.1. Step 2: Import into Reader Software

Import Logs : Navigate to the Attendance or Device tab. Select Import Transaction Log or Read User from USB . Specify the folder path where your .dat file is saved.
def read_attlog(filepath): with open(filepath, 'rb') as f: data = f.read() records = [] for i in range(0, len(data), 8): if i+8 > len(data): break uid, ts = struct.unpack('<II', data[i:i+8]) dt = datetime.datetime.fromtimestamp(ts) records.append((uid, dt)) return records zkteco dat file reader
ZKTeco provides software to parse these logs. The Extractor tool is designed to automatically communicate with ZK devices and generate human-readable text files from the logs. Official, reliable, handles encryption. Cons: Requires ZK-specific software installation. 2. Open Source / Third-Party Parsers
When you export data from a ZKTeco terminal (like the uFace or MB series), the resulting .dat file—often named something like 1_attlog.dat —contains raw attendance logs. This includes: : The unique number assigned to the employee. Select Import Transaction Log or Read User from USB
