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.

What does a biometric device do?
*winks*
Who invented the biometric device?
Haylo
Is the face recognition system an example of biometric device?
Yes, face recognition system is an example of a biometric device because it uses unique physical characteristics of a person's face to verify their identity.
Which two devices are considered input devices?
biometric authentication device digital camera
Is a biometric device a input or output 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.
What is a biometric device?
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.

How much does a biometric input device cost?
from $69.95 and up
What is the most use biometric device today?
finger print
What alternative input device measures biometric identifiers?
Iris scanners and fingerprint scanners are alternative (biometric) input devices for computers.
