3.2.3.2.4. Authentication Type    
There are up to 12 different ways a user can be authenticated at the terminal, this provides 
flexibility for users who do not have a card, or have an unreadable fingerprint, or where extra 
verification is needed for authentication. This depends on the setup by the administrator. 
 The four basic authentication methods are:   
  Fingerprint 
  Card 
  ID 
  Password 
Combinations of the four basic methods are available.   
 1)  Fingerprint Only – the user can enter their fingerprint on the fingerprint sensor and the 
terminal will authenticate the result. 
 2) Card Only – the user can swipe their card at the terminal and the terminal will authenticate the 
result 
 3) ID & Password – the user enters their ID, the terminal will request the user to then enter their 
password. 
 4) Card & Fingerprint – the user swipes their card at the terminal then the terminal will request 
the user to enter their fingerprint.   
 5) Fingerprint & Password – the user enters their fingerprint on the fingerprint sensor and then 
the terminal will request the user to enter their password. 
 6) Fingerprint OR Password – the user can either enter their fingerprint only, OR the user can 
enter their ID followed by their password. 
7) Fingerprint OR Card – the user can either enter their fingerprint only OR swipe their card only. 
 8) Card OR Password – the user can either swipe their card OR enter their ID followed by their 
password. 
 9) Card & Password – after the user swipes their card the terminal will request the user to enter 
their password. 
 10) ID & Fingerprint OR Card & Fingerprint – after the user enters their ID the terminal will 
request the user to enter their fingerprint OR the user can swipe their card, then the terminal will 
request their fingerprint. 
 11) ID & Password OR Card & Password – this is a combination of #3 or #9. The user can 
enter their ID followed by their password OR swipe their card first then enter their password. 
12)  Card & Password & Fingerprint – The user must enter their card first, followed by their 
password, then their fingerprint. If the card is not entered first the authentication will fail. 
 Note: For password authentication the user must always first enter their ID.
