Common Authentication Problems
Most authentication failures occur because of the following easily-corrected problems:
• Wrong finger—using one that doesn’t have a template stored on the iButton or card
• Finger too wet or dry
• Pressing too heavily or lightly
• Cut finger or otherwise changed
• Finger moved during reading
• Finger positioned incorrectly
If an individual consistently has problems authenticating him or herself, you may want to re-
enroll this individual using different fingers.
