While the vast majority of fingerprints can be used with ievo fingerprint readers, there are a few occasions where some fingerprints can be tricky to capture.

These instances usually occur when a finger has been heavily damaged, causing permanent surface and subsurface skin abrasions.

While it is uncommon, studies have shown that one out of two hundred fingerprints can be problematic when using biometric readers. 

Yes, even though it may seem like the technology is against you, there are methods that can be attempted to combat some problem fingerprints.

When registering a known problem finger, or if problems persist with a registered fingerprint, try registering all of the user’s fingers, including the thumbs. This will help give the user a number of options when trying to gain access.

To register multiple images of the same fingerprint access the ‘Manage Fingerprint’ section of the ievo registration software. If using an alternative registration software package, please refer to your user manual or ask your software provider for assistance.

Another method is to register multiple images of the same fingerprint from different rotational angles. Start with scanning the left side of the finger, and then registering multiple images of the finger as you roll the finger to the right. This can build up a full image of the finger from different degree angles that may help with enabling the user to use the system. Keep scanning different angles until the system states a good image has been captured.
