Identity Verification

The S900 will NOT record an employee’s attendance OR allow door

access UNTIL the individual’s identity is verified.

The S900 uses various methods to verify a user’s identity:

• Fingerprint Matching

• Password Matching

• Card Matching (optional)

The S900 supports two methods of fingerprint matching, 1:N and 1:1.

1: N Fingerprint Matching

When using 1:N Fingerprint Matching, the S900 will place the

fingerprint (“1”) in its temporary memory and then compare it to ALL

(“N”) fingerprint templates stored in the S900 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.
