1.6 Authentication types
With the NITGEN access control system, you can use fingerprints,
passwords, and RF cards (optional) for authentication. Depending
on customer environment, you can use one of the following
authentication types as you need.
 Fingerprint authentication
Use fingerprints to validate access authentication with the following
types:
• 1:1 authentication
In this mode, enter a pre-registered ID first and then a fingerprint.
The enrolled fingerprint corresponding to the ID will be compared
to the entered fingerprint on a 1:1 basis. The 1:1 authentication
type takes a short time regardless of the number of users. There
is no need to make any special settings in the system. After
entering the ID, enter the fingerprint to perform authentication.
• 1:N authentication
Only enrolled fingerprints are used for authentication. Though the
authentication procedure is simple, this method will take a little
longer than the 1:1 authentication if there are many users. There
is no need to make any special settings in the system. But
because there were many users, so it takes too much time to
authenticate, use ‘1:N Timeout’. The user who wasn’t
authenticated in timeout will have fail message. Refer to the ‘1:N
Timeout’ for more information.
• Short ID (SID) authentication
The user ID can be 4 – 15 digits long depending on the initial
setting. This method simplifies ID input procedure. Instead of
entering the entire registered ID, you can enter only the first part
