SAGEM FINGERPRINT READER - FALSE ACCEPTANCE RATE
The Sagem Morphosmart reader is currently hardcoded in the 8 and 16 bit firmware to use a matching threshold level
of 5, when identifying a user. This corresponds to a False Acceptance Rate (FAR) of <0.01%. This can now be adjusted
on a cabinet-by-cabinet basis in the ‘Configure Firmware’ dialogue.
The following levels can be set:
1 FAR < 1 % There are less rejections, but more recognitions
2 FAR < 0.3 %
3 FAR < 0.1%
4 FAR < 0.03 %
5 FAR < 0.01 % Recommended value
6 FAR < 0.001 %
7 FAR < 0.0001 %
8 FAR < 0.00001 %
9 FAR < 0.0000001 % There are less recognitions and more rejections.
Adjusting the value below 3 or above 7 is not recommended except in special circumstances.
