Access Controller : (3) NITGEN - NAC-3000 / NAC-2500 / 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, you should input ID first and then your 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
  In this mode, you need to enter only fingerprint without ID. 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 1234567, 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.
  
  
  
• Group authentication
  For group authentication, you can specify a group ID of 1 - 4 digits long for each user group. You will enter a group ID and a fingerprint for authentication. For example, you can use the unit number for public housing like an apartment as a group ID. You can specify a group ID when you register a user. Unlike other methods, you must enter the group ID, and then press F1 before entering the fingerprint to perform group authentication. ( NAC-3000 only support the function of “Group authentication”.)
  

Password authentication
A password of 4 - 8 digits long is used to validate access authentication. You can use this method in such a special case as when the fingerprints are damaged.


RF card authentication (optional)
The RF card of a user is used to identify the user. The card number must be registered into the system to use the card.


Note :
The dedicated terminal to RF card supports user authorized type of password and RF card ID.
