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.
- User denied entry by entry mode error door mode is not correctly programmed using invalid reading device
- Security Expert
- Suprema BioEntry W2 fingerprint reader
The sensitivity settings in the Suprema software are too sensitive resulting in missed fingerprint reads.
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.
