Biometrics is used in many places and there is a bright future for them. Coca Cola has recently replaced time card system with hand scanning machines. Finger print scanners are being used in many states of the US. They have been used to trace social welfare fraud. An iris pattern identification system is being used in Cook County, Illinois to ensure that right people are released from jail. ATM machines have been installed with finger scanners to prevent theft and fraud in Indiana (Jain, 2005). The world’s major credit card companies are using finger scanning devices to protect credit card information and save the consumer from credit card fraud. Walt Disney World in Orlando has implemented a hand scanning system to prevent people from lending their passes to others. Biometric systems are being widely used for security and convenience. Major departments of the United States government like the FBI, TWIC and RT are using such technologies. Many biometric identification systems have been installed in airports for security and preventing terrorism. New biometric technologies are being developed using diverse physiological and behavioral characteristics. These technologies are in various stages of development. Vein scan technology identifies a person based upon blood vessel patterns. This technology uses infrared light to detect vein patterns. It is available for commercial purposes. Facial thermography detects heat patterns which are created by blood vessels that branch. These heat patterns are also emitted from the skin. An infrared camera is used to capture images. The advantage of this system is that it does not require close physical contact. These systems can also work in darkness. However these systems are very expensive to ... ... middle of paper ... ...ology and Its Applications' [U.S.] Department of Defense Counterdrug Technology Development Program Office, 10 August 2001, at Bowman E.
