Pips Wizard Pro Indicator

The primary benefit to using facial recognition as a biometric authenticator is that people are accustomed to presenting their faces for identification and instead of ID card or photo identity card this technique will be Pips Wizard Pro beneficial in identifying a person. As the person faces changes by the age or person goes for plastic surgery, in this case the facial recognition algorithm should measure the relative position of ears, noses, eyes and other facial features.


Hand geometry is techniques that capture the physical characteristics of a user's hand and fingers. It analyses finger image ridge endings, bifurcations or branches made by ridges. These systems measure and record the length, width, thickness, and surface area of an individual's hand. It is used in applications like access control and time and attendance etc. It is easy to use, relatively inexpensive and widely accepted.

A camera captures a 3 dimensional image of the hand. A verification template is created and stored in the database and is compared to the template at the time of verification of a person. Fingerprint identification.Currently fingerprint readers are being built into computer memory cards for use with laptops or PCs and also in cellular telephones, and personal digital assistants. It is successfully implemented in the area of physical access control.



This technique involves scanning of retina and iris in eye. Retina scan technology maps the capillary pattern of the retina, a thin nerve on the back of the eye. A retina scan measures patterns at over 400 points. It analyses the iris of the eye, which is the colored ring of tissue that surrounds the pupil of the eye. This is a highly mature technology with a proven track record in a number of application areas. Retina scanning captures unique pattern of blood vessels where the iris scanning captures the iris. The user must focus on a point and when it is in that position the system uses a beam of light to capture the unique retina characterstics.It is extremely secure and accurate and used heavily in controlled environment.
