Fingerprint configuration
Security level
We provide a setting to control the behaviour of the fingerprint matching algorithm, which decides whether a finger is an acceptable match to a user. The Security level setting can be adjusted from Low to High.
A low security level will make it easier for a user to get their finger accepted, but with the trade-off of lower accuracy, making it more likely that fingers will be incorrectly identified as another user, causing clockings to go through as the wrong person.
Conversely, a high security level will reduce the chance of a user being incorrectly identified, but at the cost of making it trickier for users to get their fingers accepted.
See the Accuracy and performance section for details on the effects of different values chosen here.
Troubleshooting
If a particular user is having trouble clocking using their fingerprints, re-enrolling is the best course of action. Try using other fingers when enrolling, and make sure you can successfully test the enrolments.
If after re-enrolling they are still unable to clock, they may need to use either faceprint or proximity card instead – a small proportion of the population just don’t have enough detail in their fingerprints to identify them.
