Due to the nature of biometric attendance systems, they can be built around any number of human characteristics. The most common of which include:
1. DNA – Analysis of segments of individual DNA
2. Ear – Identification by ear shape
3. Eye – Using the characteristics of the iris, or the pattern of veins and retina, to identify a person
4. face – Analyzing facial features or patterns to authenticate or identify a person
5. fingerprint – Identifying a person using the small ridges and valleys of a person’s finger
6. finger geometry – Analyzing finger 3D geometry to determine a person’s identity
7. hand geometry – Analyzing geometric characteristics of the hand, including finger length and hand width
8. odor recognition – Using a person’s natural scent to identify it
9. sound – Identifying, verifying and authenticating speakers based on their voice
10. signature identification – Using a person’s signature and handwriting style to prove their identity
