is a global leader in biometric security, producing millions of fingerprint and facial recognition devices for access control and time attendance. However, even the most reliable hardware can encounter a frustrating roadblock: Authentication Failure.

Section 3: Fixing Software and Database Synchronization Errors

: If only certain users experience failure, their profiles may be corrupted. Delete the existing biometric data and re-enroll them, ideally adding multiple entries (e.g., both index fingers) for better reliability. zkteco authentication failure solution best

Dry skin struggles to register minutiae points. Moistening the finger slightly or rubbing it against the forehead for natural oils can instantly resolve scanning failures.

Lowering this too far increases the risk of "false identifies." Sync Software and Firmware is a global leader in biometric security, producing

Create an empty folder named DeleteLicense on a FAT32-formatted USB drive. Shut down the device, plug in the USB, and restart it.

Biometric sensors wear down over time, and fingerprints can change due to cuts, dryness, or oil buildup. If only one or two users are facing issues, the biometric template is likely corrupted. Delete the existing biometric data and re-enroll them,
