Do we meet this requirement with Suprema fingerprint devices?

FAR : 0.0001%

FRR:  0.01%


These figures are not very accurate because the rates depend on too many factors; however, this value is something that is advantageous to Suprema because we have even higher security settings. These are also different from algorithmic and real life experiences as the finger input has too many variables in real life. With ideal conditions and correct settings we can meet those specifications.


The FAR/FRR means FAR and FRR are correlated as the below graph shows.

The FAR/FRR rate changes opposite way. If you lower the FAR, the chance of FRR increases, and this threshold can be configured by adjusting security level.

Suprema fingerprint products support three levels of security level control to adjust the threshold. (Normal/Secure/More Secure)


The security level control has a feature of automatic adaptation depending on the number of templates. The following table shows the relationships between the automatic security levels and the number of enrolled templates. For example, when the security level is Automatic Secure(0x51) and the number of enrolled templates is 500, the actual FAR for identification will be 1/10,000,000. The security level for verification is not changed.

Therefore, it is not appropriate to fix the FAR rate. But if you absolutely need to write down some values, you may say that Suprema devices does support

FAR : Less than or equal to 0.0001%

FRR: Less than or equal to 0.01%

For FaceStation 2 you can provide the following guide

FAR: 1/5,000,000

FRR: less than 1%
