The following screen appears if you select the [System] -> [Finger] in the main menu.
▶Fake Finger Detection
It sets the LFD level to prevent the fake fingerprint input. If you set the LFD level
higher, the preventing function of the fake fingerprint input such as rubber, paper, film,
or silicon can be more strengthened, but the fingerprint also can be hard to enter if the
finger is dry too much.
▶ FP template format
It determines the format of fingerprint template. When some applications using SDK
need another format of the fingerprint, the fingerprint template format of the terminal
can be changed. But, if using UNIS server, it should be set the same with the
template format of the server.

the most optimized format related with all the functions using fingerprint (1:1
level, 1:N level, authentication speed, and fake fingerprint detection), and the
authentication can be fulfilled rapidly and correctly.
- ISO Standard: Fingerprint data is saved as ISO template which is 500 bytes for each
- ISO Extended: Fingerprint data is saved as ISO template which is 600 bytes for each
template.
If you change the template format of the fingerprint, the following message box
