People have been talking about biometrics as a financial services security tool for a while now. At least one recent report suggests  that the financial sector is indeed emerging as a "potential adopter" and driving force in the global biometric market, which is set to grow at a near 20 percent average annual growth rate through 2012.
Biometrics can be used at all levels, at the employee and customer authentication levels and beyond. A glimpse of the future comes from Warsaw, where one bank says it is the first in Europe to install a biometric ATM, "allowing customers to withdraw cash simply with the touch of a fingertip." The digit-scanning ATM runs on a system developed by Hitachi. The company says that "an infrared light is passed through the finger to detect a unique pattern of micro-veins beneath the surface, which is then matched with a pre-registered profile." Tests have indicated a one in a million false acceptance rate.
