retinal scan
The type of biometric device you are referring to is an iris scanner. It captures the unique pattern of the colored part of the eye, called the iris, to identify individuals. The infrared beam helps in distinguishing the intricate details of the iris for accurate identification.
A fingerprinting scan is a very common biometric device. There are also iris matching scanners for high tech security. @Nottingham YE$
20. This type of biometric device uses an infrared beam to scan the color pattern surrounding the pupil of the eye:
Broadly, a "biometric device" is any device that measures a biological function or trait. As related to computers, biometric devices are used to control access and/or verify identity. Voice recognition, retinal scanners, palm/fingerprint scanners are all examples of biometric devices. A biometric scanner will take a picture (your fingerprint, your retina) and match it to a previous scan kept on file. Other types of biometric devices, such as voice recognition systems, will record your voice and compare the recording to a sample on file.

you can use a biometric device instead of typing in an password on your computer. it is a much better way of keeping your stuff personal because everyone has different fingerprints. but anyone can get your password to a cmoputer. <hacking>
