Sometimes the device is "too strict." You can lower the security threshold to allow for minor variations in a scan. Go to System > Fingerprint . Find Threshold: Locate the 1:N Threshold setting. Lower the value: Drop it slightly (e.g., from 45 to 35).
: If a "COM Key" is set on the device, the same key must be entered into the software settings. A mismatch here will result in an immediate connection failure. 3. Software and Firmware Fixes
When a user's biometric authentication is repeatedly rejected, the issue often lies with the user's finger, the sensor's cleanliness, or the software configuration.
: If an individual user consistently fails, delete their old profile and re-enroll their fingerprint or face. Admin Password Resets zkteco authentication failure solution best
I can provide tailored menu paths and specific software configuration steps based on your setup.
: Poor lighting, dirty camera lenses, or significant changes in appearance (e.g., new glasses or hats) can interfere with facial scans. Install devices at eye level in well-lit indoor areas. Software and Network Configuration :

ZKTeco devices let administrators adjust the strictness of the matching algorithm. Enter the device using administrator credentials.
Outdated firmware causes algorithm bugs that reject valid biometric reads.
Register multiple fingers per user (e.g., left + right index). Lower the value: Drop it slightly (e
When your attendance software cannot connect to the device or authentication data fails to sync, follow this network troubleshooting checklist.
