Iris scanner in action to identify people. A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice ...
Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual's eyes.. Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some ...
A retinal scan is a biometric technique that uses unique patterns on a person's retina blood vessels. It is not to be confused with other ocular-based technologies: iris recognition , commonly called an "iris scan", and eye vein verification that uses scleral veins.

Aran Safir (March 29, 1926 – January 21, 2007) was an American ophthalmologist and inventor. He is known for inventing a groundbreaking iris recognition scanner. This technology has been widely adopted in the security sector, ranging from the U.S. Department of Homeland Security to Google. [1]
IRIS relied on biometric technology to authenticate identity and was part of the e-borders initiative of the UK Government. The main factor behind the decision to decommission IRIS was the cost of staffing the enrolment offices in airport terminals, whereas face recognition only required submitting a Passport-type photograph acquired in a photo ...
Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor. Scanners using CISs are much smaller than ones that use CCDs, use typically a tenth as much power, and are particularly suitable for low power and portable applications, often powered over USB.

A line-scan camera is a system for producing two-dimensional images using a single sensor element. They normally consist of a rapidly rotating mirror or prism placed in front of the sensor to provide scanning in one direction while the movement of the recording material, often photographic film , provides scanning in the second direction.
