Note: If the system directs you to reposition your finger, do not slide the
finger into place. Rather, lift your finger from the sensor and then place the
finger in the recommended position.
d. Apply firm, even pressure. If you apply too little pressure, the sensor
might not detect your finger. If you apply too much pressure, the image
might be too dark. In either case, the enrollment can fail.
e. Hold your finger on the sensor until the image frame turns green, the LED
flashes green, and the timeclock emits a tone; then remove it.
Administrators: To disable the tone, access the Device Configuration
page, and select General Settings > Display. Then, clear the Enable tone
for response check box.
The system grades the scan quality as Good, Fair, or Poor, and prompts
you to re-scan the same finger.
3. When instructed, re-scan the same finger. Repeat the process until you have
obtained three scans. The system uses the three images to create a single
template.
The results pages for the three scans include the following information:
Parameter Description
Enrollment Good
Fair

Quality Score A measure of the useful data that the sensor detected in the
fingerscan. Some fingers have indistinct ridges, scars, or
other characteristics that can lower the quality score. The
system uses the following scale:
• Good: 60 or greater
• Fair: 40–59
• Poor: 39 or less
Threshold A measure of how closely an employee’s live fingerscan
must match the stored enrollment template. There are four
threshold settings: High, Normal, Low, and None.
