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.
• 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
of the ID for authentication. For example, if the user ID is 1234
567, enter 12 only and then the fingerprint. Then the system will
perform 1:N authentication for all Ids that start with 12xxxxx.
There is no need to make any special settings in the system.
