Proper Finger Placement
The user’s nger should completely cover the sensor. The nger should be placed at
and in the center of the sensor. The nger should cover at least 80% of the sensor as
shown below
Identity Verication
The US922 will NOT record an employee’s attendance OR allow door access UNTIL
the individual’s identity is veried.
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 ngerprint matching, 1:N and 1:1.
1: N Fingerprint Matching
When using 1:N Fingerprint Matching, the US922 will place the ngerprint (“1”) in its
temporary memory and then compare it to ALL (“N”) ngerprint 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 nger on the sensor. 1:N is principally a 1-touch
matching. It is the FASTEST and EASIEST method of ngerprint matching.
The nger should NOT be placed in the following positions:
Upright
Sideways
Skewed
Partial
