Biometric identification systems
Biometric identification systems can be grouped based on the main physical characteristic that lends itself to biometric identification:
• Fingerprint identification
Fingerprint ridges are formed in the womb; you have fingerprints by the fourth month of fetal development. Once formed, fingerprint ridges are like a picture on the surface of a balloon. As the person ages, the fingers get do get larger. However, the relationship between the ridges stays the same, just like the picture on a balloon is still recognizable as the balloon is inflated.
• Hand geometry
Hand geometry is the measurement and comparison of the different physical characteristics of the hand. Although hand geometry does not have the same degree of permanence or individuality as some other characteristics, it is still a popular means of biometric authentication.
• Palm Vein Authentication
This system uses an infrared beam to penetrate the users hand as it is waved over the system; the veins within the palm of the user are returned as black lines. Palm vein authentication has a high level of authentication accuracy due to the complexity of vein patterns of the palm. Because the palm vein patterns are internal to the body, this would be a difficult system to counterfeit. Also, the system is contactless and therefore hygienic for use in public areas.
• Retina scan
A retina scan provides an analysis of the capillary blood vessels located in the back of the eye; the pattern remains the same throughout life. A scan uses a low-intensity light to take an image of the pattern formed by the blood vessels. Retina scans were first suggested in the 1930's.
• Iris scan
An iris scan provides an analysis of the rings, furrows and freckles in the colored ring that surrounds the pupil of the eye. More than 200 points are used for comparison. Iris scans were proposed in 1936, but it was not until the early 1990's that algorithms for iris recognition were created (and patented). All current iris recognition systems use these basic patents, held by Iridian Technologies.
• Face recognition
Facial characteristics (the size and shape of facial characteristics, and their relationship to each other). Although this method is the one that human beings have always used with each other, it is not easy to automate it. Typically, this method uses relative distances between common landmarks on the face to generate a unique "faceprint."
• Signature
Although the way you sign your name does change over time, and can be consciously changed to some extent, it provides a basic means of identification.
• Voice analysis
The analysis of the pitch, tone, cadence and frequency of a person's voice.

Walt Disney World
Disney World Parks have been right away relocating from a comparison two-finger Biometric reader to only one. This latest complement as we can see is really quick as well as simple. The Biometric complement is a confidence apparatus which measures different tools of your finger,
