A biometric system is a recognition system, which makes a personal identification by determining the authenticity of a specific physiological or behavioral characteristic possessed by the user. This method of identification is preferred over traditional methods involving passwords and PIN numbers for various reasons:
·         The person to be identified is required to be physically present at the point of identification.
·         Identification based on biometric techniques eliminates the need to remember a password or carry an identity.
But it has its own disadvantages; Behavioral traits such as voice and signature are vulnerable to spoof attacks.
          The prominence and acceptance of biometric technologies such as fingerprinting, facial recognition, hand geometry, and iris recognition may leave little demand for other modalities. However, the emerging vein-pattern recognition technology, with its own unique features and advantages, has maintained its position against the others.

         The up-and-coming biometric technologies include vein, DNA, ear, and body odor recognition. Of these, vein pattern recognition is gaining momentum as one of the fastest-growing technologies. It is on course to become the newest entrant to mainstream biometric technologies, moving from the research labs to commercial deployment.
