Paper Reviews(2)Why do we select the hand?It is usually an uncovered part of the body and it has sufficient mobility.It has a reduced amount of hair especially in the front of the hand.The veins are closer to the surface than in other parts of the body and therefore easier to scan.The vein pattern is intricate enough to allow sufficient criteria for positively detecting various subjects even identical twins.*Septimiu Crisan, Joan Gavril Tarnovan, and Titus Eduard CriUan,A Low Cost Vein Detection System Using Near Infrared Radiation, IEEE Trans. Biomed. Eng ,2007.
