1.1. HAND HAND

The three dimensional shape of a The three dimensional shape of a person’s hand has several advantages person’s hand has several advantages as an identification device. Scanning a as an identification device. Scanning a hand and producing a result takes hand and producing a result takes 1.2seconds.It requires little space for 1.2seconds.It requires little space for data storage about 9 bytes which can fit data storage about 9 bytes which can fit easily magnetic strip credit cards. easily magnetic strip credit cards.

CONCLUSIONCONCLUSION A range of biometric systems are in A range of biometric systems are in

developments or on the market because no one developments or on the market because no one system meets all needs. The trade off in system meets all needs. The trade off in developing these systems involve component developing these systems involve component cost, reliability, discomfort in using a device, the cost, reliability, discomfort in using a device, the amount of data needed and other factors. Butamount of data needed and other factors. But the application of advanced digital the application of advanced digital techniques has made the job possible. techniques has made the job possible.
