Fingerprints Not Reading at Timeclock

Overview

Users may experience issues with their fingerprints not reading on the biometric timeclock device — even after multiple attempts or re-registration. This issue can occur due to finger dryness, environmental factors, or device matching configurations.

Issue Description

• Users report fingerprints are not recognized at the timeclock

• Re-registering the same or different fingers does not resolve the issue

• Multiple users affected; problem persists even after using different fingers

Step 1: Improve Fingerprint Readability with Moisture

To address dryness or weak ridge definition:

• Use a moist sponge or slightly damp paper towel to lightly moisten the finger before scanning

• This helps improve readability, especially on dry or rough fingers

• Do not use wet fingers — just lightly moist

Note: This step significantly improves success during enrollment and read attempts.

Step 2: Enable One-to-One Fingerprint Matching

Instead of using one-to-many matching (default), configure the device for one-to-one matching:

• User enters their Badge ID first

• Then scans their fingerprint for validation

• This reduces false mismatches across multiple fingerprint templates stored in the system

Tip: This is especially effective in environments with many users or when fingerprint quality is inconsistent.

Step 3: Lower the Matching Threshold (Caution)

As a last resort, you may adjust the device’s fingerprint matching threshold:

• Lowering the threshold increases match tolerance

• However, this can introduce false positives (e.g., one user’s fingerprint matching another’s)

• Use only if absolutely necessary and test thoroughly

⚠ Important: Always consult with Microix support before modifying biometric thresholds. Improper tuning can compromise security.

Additional Notes

• Ensure the fingerprint scanner surface is clean and unobstructed

• Avoid scanning with dirty, oily, or injured fingers

• Try enrolling multiple fingers for fallback if one fails
