Palm Scan

An example of a physiological biometric factor, which is unique to a subject. It uses near-infrared light to measure vein patterns in the palm, which are as unique as fingerprints. Some palm scans identify the layout of ridges, creases, and grooves on a person’s palm to establish identity or provide authentication. See palm topography.
