What is a Biometric device?
A biometric device is a device by which a machine can read people’s personal information to tell who they are. They are often used in security situations such as the military and other secure locations. Biometric devices are used to read fingerprints, DNA, eyes, and voice recognition. These devices are very important and make excellent security barriers because they are very hard to forge. In the future it is likely that many passwords and security systems will use biometric devices.
