Good Image vs Bad Image
A good fingerprint image is one in which the core of the fingerprint is well-defined and easily
recognizable. The core of a finger is defined as the “point located within the inner most
recurring ridge”, it is normally located in the MIDDLE of the fingerprint. It is therefore critical
when enrolling that you place the finger on the scanner where the entire core can clearly be
seen.
An example of a good & bad image is displayed as follows:
Bad Image: An image where the crackles &
displacement of the fingerprint core makes
it unrecognizable.
Good Image: The whole fingerprint
core can be seen clearly.
