FP Sensor
Sensitivity
To set the sensibility of fingerprint acquisition. It is recommended to use the default level
“Medium” in normal conditions
. When the environment is dry, resulting in slow
fingerprint detection, you can set the level to “High” to raise the sensibility; when the
environment is humid, making it hard to identify the fingerprint, you can set the level to
“Low“.
1:1 Retry
Attempts
In 1:1 Verification, users might forget the registered fingerprint, or press the finger
improperly. To reduce the process of re-entering user ID, retry is allowed.
