Security level 4 is recommended to guarantee a reliable system that grants easy access
to authorised users while barring unauthorised users.
When should the higher and lower levels be selected? A lower security level is selected
when there is little risk of an unauthorised user attempting to log on, and
a very fast verification process is desirable. A higher security level is selected when secu-
rity is the main concern. In this case, the verification process may take a little longer.
NOTE: An experienced biometric user is less likely to be falsely rejected than a novice
biometric user. The FRR decreases as a user gets more used to biometric logon and learns
a proper finger placement.
