3. Iris Recognition  Iris recognition technology relies on the distinctly colored ring that surrounds the pupil of the eye

4. Retinal Scan  The blood vessel patterns of the retina

5. Hand Geometry  Hand geometry relies on measurements of the width, height, and length of the fingers, distances between joints, and the shape of knuckles.

6. Fingerprint Recognition  Fingerprint recognition technology is probably the most widely used and well-known biometric.  Finger print recognition relies on features found in the impressions made by distinct ridges on the fingertips.  Used for attendance in schools and work.

7. Facial Recognition  Face recognition technology identifies individuals by analyzing certain facial features such as the upper outlines of the eye sockets or sides of the mouth.

8. Voice Recognition  Voice recognition technology identifies people based on the differences in the voice resulting from physiological differences and learned speaking habits.  an imposter may be able to imitate someone's voice extremely well, but will not fool a voice identification system

9. Emerging Technologies  vein scans  facial thermography  DNA matching  odor sensing (captures chemicals coming out of your pores)  blood pulse measurements  skin pattern recognition  Nail bed identification  gait recognition (how you walk)  Ear shape recognition.
