z Admin, Administrator 
- As a user who can enter into the terminal menu mode, he/she can 
register/modify/delete terminal users and change the operating environment 
by changing settings. 
- If there is no administrator for a terminal, anyone can change the settings, so it 
is recommended to register at least one administrator. 
- Caution is required with registration and operation because an administrator 
has the right to change critical environmental settings of the fingerprint 
recognition unit. 
z Authentication Method 
- Various kinds of authentication including RF(card) authentication, PW 
(password) authentication or a combination of these methods 
Ex) RF|PW: card or password authentication; ID&password is used for 
authentication if card is not used. 
z Function keys 
- [F1], [F2], [F3], [F4] are used, and they are used for direct authentication and 
each key represents each authentication mode. 
z [NS] / [SN] / [NO] Mode 
- [NS] Mode: When there is a live connection to the server, authentication is 
done through the server. If not, it is done through the terminal. 
- [SN] Mode: Even though there is a live connection to the server, authentication 
is done through the terminal and the result is forwarded to the server in real 
time. However, in the case of 1:1 authentication, if the entered user ID is not 
registered in the server, authentication is done through the server. 
- [NO] Mode: Even though a user is registered in the terminal, authentication is 
done through the server in any event.
