What makes iris scans an effective technology for identifying people?
each person has there own "eyeprint" (if you will). in the back of your iris there is small little fibers that reflect light back which we have devolped over millions of years to block uv rays. iris scanners pick up the light bounced back from your eye. no one on earth has a "twin" iris structure that's why it works so well. fingerprint scanners can be foiled by someone stealing your fingerprint off of an object you own or use every day you can not steal a iris structure that's what makes it so effective.
What part of the body does a iris scanner look at?
An iris scanner uses visible and near-infrared light to scan the iris of an eye. The iris scanner takes a picture and uses it to compare that to an image already stored in a database to see if there is a match. Since everyone's eyes are unique, iris scanners are becoming more popular for identifying people in security situations.

What are the pros and cons for iris scan?
PRO-Probably the main pro of iris reading software is that it is almost 100 % accurate. Not only is it accurate, but it offers the advantage of being convenient as well. Iris patterns do not require direct contact with the face and some biometric scanners can focus on the eye and find the meaningful patterns while people are several feet away. It is fast as well, which makes it an excellent choice for many companies.CON-Although irises greatly differ, today's face scanners are not yet able to be as accurate as they should be which is a con to iris reading. Sometimes contacts, tears, long eyelashes, or dark eyes can throw off the machines, making them a choice that doesn't yet have the accuracy of other forms of face biometrics.
Which brand produces cheap scanners?
