Place your finger flat on the sensor. The arches, loops and whorls that distinguish your prints from others' are in the pad of your finger, not the tip. Also make sure that you position your finger on the scanner the same way each time. Apply light pressure — pressing too hard can distort the ridges in your skin.

In addition to taking images of human and pet prints, Thumbies® Snap™ also creates visualized soundwaves from recorded voices, and captures handwriting images.
