Proper Finger Placement
The user’s finger should completely cover the sensor. The finger should be placed flat
and in the center of the sensor. The finger should cover at least 80% of the sensor as
shown below
Identity Verification
The US922 will NOT record an employee’s attendance OR allow door access UNTIL
the individual’s identity is verified.
The US922 uses various methods to verify a user’s identity:
•
Fingerprint Matching
•
Password Matching
•
Card Matching (optional)
Fingerprint Matching
The US922 supports two methods of fingerprint matching,
1:N
and
1:1.
1: N
Fingerprint Matching
When using
1:N
Fingerprint Matching, the US922 will place the fingerprint (
“1”
) in its
temporary memory and then compare it to ALL (
“N”
) fingerprint templates stored in
the US922 database (up to 2800 templates).
By using
1:N
matching, the user enjoys the convenience of not entering his/her User
ID number prior to placing his/her finger on the sensor.
1:N
is principally a 1-touch
matching. It is the FASTEST and EASIEST method of fingerprint matching.
The finger should NOT be placed in the following positions:
Upright
Sideways
Skewed
Partial
