Number of biometric check attempts
Description
In order to reduce the False Rejection Rare, the terminal allows the user to place again
his finger on the sensor for a 2
nd
try, when the initial biometric check fails.
This 2
nd
try is allowed by default, but can be disabled.
The 2
nd
try allows the user to upgrade the finger placement, or to place another finger.
In addition, and also to reduce the FRR, during this 2
nd
try, the terminal executes a
more powerful biometric check (which is also little bit slower).
Configuration key
By default, the two attempts mode is activated, but can be disabled.

Identification mode
If the finger of the user is not recognized, he has 5 seconds to place again one of his
fingers on the sensor. If a finger is placed on the sensor after this delay, then the
terminal process it as a new access request.
The value of this delay is defined by a dedicated configuration key.

Authentication mode
In authentication mode, if the user place on a sensor a finger which is not recognized,
then the terminal request him to replace his finger without presenting his card again.
The result is sent only after this second attempt.
The wait delay for a finger on the sensor is specified by one configuration key.
