pattern
If the problem occurs with 1:N verification, try 1:1
verification, if this is an available. Contact the
administrator. You may need to enrol another finger or
use a password verification method instead.

When enrolling, we recommend you enrol users with their left or right index or
middle finger. Check the fingers for any injuries or wear.
If the user’s fingers are small, it may be preferable to use a thumbprint.
Few people’s fingerprint quality is too poor to verify but in difficult cases it is
advisable to use an ID & fingerprint verification method with the threshold reduced
accordingly. In extreme cases, use password verification to avoid fingerprint
verification problems.
