Issue
Valid Users are randomly unable to gain access when presenting at a Suprema biometric reader. Sometimes they are able to gain access but others they are not and see user denied events in the events window.

Environment
- Security Expert
- Suprema BioEntry W2 fingerprint reader
Cause
The sensitivity settings in the Suprema software are too sensitive resulting in missed fingerprint reads.
Resolution
Reducing the fingerprint sensitivity from the default setting of 7 to a setting of 5 may allow fingerprints to be read more reliably.
The sequence used to authenticate the User can also result in more frequent read failures.
- Presenting a valid card then an invalid (or bad read) fingerprint and then presenting the card again, the sequence starts all over again and will result in a user denied event.
- If the user presents the correct finger (after presenting the wrong finger) or tries the same finger again within the configured timeframe they will be granted access.
