Biometric technology.
The website Wikipedia has an extensive article about the scientific use and moral implications of using biometric facial recognition. The Department of Justice also has a website that gives information about how the United States government is using this technology.

According to the US biometric military task force, biometric capabilities enabled US troops to capture more than 400 "high value individuals" in Iraq and Afghanistan in 2008. Assistant director of the task force Lisa Swan said: " very well we catch the bad people. " After several years of compiling large biometric databases containing credentials for more than 2.5 million Iraqis, US Military has been connected to technology. Fingerprints and irises are checked against the Biometric Verification or iron of the persons being requested before Iraq is allowed to pass through the checkpoints or to enter other facilities.
A biometric ID card is a card with some of a person's biometric information stored on it in electronic form. Biometric information generally falls into two categories - physical characteristics and behavioral characteristics. Typical physical characteristics include retina patterns, fingerprints, facial features, DNA, or body dimensions. Behavioral characteristics include rhythm and pressure when typing on a keyboard, handwriting, or vocal patterns (although vocal patterns can also be partly physical). A few countries are looking to incorporate biometric information into passports. Others are already working to issue residents new identity cards that have some of their biometric information embedded electronically. Special readers are required to retrieve the information from the card and when well designed, the reader may only translate the biometrics of the person presenting the ID into a hash which is then compared with the hash of the corresponding information on the card.

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.
