Expiration Rule
You can set limits for the device to verify an employee, either by number (for example
100 times) or specific date(s) (for example 1st of June). Employees exceeding the limit
can no longer verify at the device or gain access. You can set the device to take any of
action below when the limit has been reached:
• Keep User, No Audit Future Punch: Device keeps employee data but will not save any
attendance records.
• Keep User, And Audit Future Punch: Device keeps employee data and attendance
records.
• Delete User: Device removes all employee data
Fingerprint Options
Threshold is the level security during a fingerprint verification process. Threshold de-
termines how many percent of minutiae points on a fingerprint template will be read
by the system.
The higher the threshold level means the device will require additional minutiae points
to verify an employee. Thus increasing its security. There are 2 sets of Threshold settings
for different verification process:
• 1:1 Matching Threshold Value: 1:1 match is where one verification method is matched
to only one template. Employee presses keypad to insert his/her ID followed by OK
button and fingerprint verification
• 1:N Matching Threshold Value: 1:N (many) match is where the verification is compared
against N templates. Employee presses finger on the scanner to verify.
• High Security: If high security is intended, the threshold value must be set to high. Do
take note that if the threshold value is set to high, users may be inconvenienced due
to the requirement may of multiple verifications of the fingerprint. For example: If
security level is set to high, the chances of identifying the wrong person will be very
low. However, you need to verify for a few times before your credentials are verified.
• Normal: This is the default setting where both the security and convenience level are
in balance.
• Low Security: If high convenience is intended, the threshold value must be set to low.
Do take note that if convenience level is high, the security level will be low, thus the
chances of inaccurate identification will be high.
