A biometric device is a computer device that uses fingerprint, voice, and retinal scanning instead of passwords. It's believed that the military uses DNA scanning.
Althogh there there are better biometric devices, face recognition is an example of biometric device because it has to recognize your face to authenticate you to a facility.
It is an input device.
Most biometric devices would be input devices although they may also utilize storage devices and output devices in their functioning. A biometric device usually takes in biometric information about a person and compares it to information stored in a database - much like username/password methods of authentication compare the username and password to the stored information for a user. Fingerprint scanners, read the fingerprint, convert it to a data stream and then compare it to the stored data previously recorded for the individual, retinal scanners read information about the retinal patterns of a user, convert it to data and compare it to stored data, etc. Note that biometric devices must rely on a storage device, but usually the storage device is not part of the biometric device. Instances of OUTPUT associated with a biometric device might be a signal to open a door or trigger an alarm, but again, the output usually comes from another device that the biometric device is connected to.
Yes they are input devices.
a biometric device is used to analyse the human body using fingerprint, eye/retina, face or hand palm vein using scanning technology
Well, it is both an input and an output device because in order for it to give you something, the output, you must input something into the Biometric reader.
A biometric scanner is device that scans certain physical characteristics and allows entry into computers or secure areas. An example of a biometric scanner would be a fingerprint reader.
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.
Iris scanners and fingerprint scanners are alternative (biometric) input devices for computers.
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>
The influence of biometric devices on either security or privacy will depend upon how they are used. Like any other device, biometric devices can be used appropriately or inappropriately. Does the use of a knife make you bleed to death? But then, maybe you will just chop vegetables.
A fingerprinting scan is a very common biometric device. There are also iris matching scanners for high tech security. @Nottingham YE$

Accu-Chek is the brand of blood-sugar testing devices, i.e. glucose meters used primarily by diabetics. It might be considered a "biometric device" in the sense that it measures a biological property, but usually the term "biometric" refers only to methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral characteristics. Since glucose levels in blood do not uniquely identify an individual, a glucose meter like those from Accu-Check would not be considered a biometric device.
Biometric devices have been traced as far back as 14th century China, where it was practiced in a form of fingerprinting used by merchants to distinguish children from one-another.
