Identifying the Fingerprint Core

A fingerprint core is a point located within the inner most recurving ridge.

Normally it is located in the middle of the fingerprint.

Most frequent types of core:

> Arches (plain and tented)

> Loops (singular and twinned)

>Whorl and Central Pocket Loop W

When placing the finger on the sensor, it is important that the Ridge-Lock is used to ensure that the fingerprint core is fully captured by the sensor.
