Can the fingerprint scanner be adjusted for sensitivity to lower a high FRR?

Most of todays fingerprint scanning units can be adjusted for dynamic threshold to control the sensitivity of the reader. If the FRR (False Rejection Rate) is too high and the threshold is lowered, the false rejection of registered users may be reduced but the FAR (False Acceptance Rate) of accepting non-registered users will increase. The FRR is inversely proportional to the FAR. Usually, the default threshold settings are the best to use for uniform consistent results.
