Biometrics-The technique of studying physical characteristics of a person such as finger prints, hand geometry, eye structure or voice pattern.

Finger Scanners

One of the basic forms of biometrics. All a person has to do is go to the scanner and put their finger on it where the scanner will then check the finger to make sure that is the person that may enter. They are used in everyday uses like amusement parks for example.

Eye/Retina Scanners

Retina scanners ar one of the most advances of biometrics used today. the perason goes up and places their eyes in front of the scanner where the scanner than checks the iris for the specific that person's DNA to see if that is a person that is allowed access. If you are willing to cutr someones eye out and then use it that would be like your only chance you would have.
