Biometric Vending Machines
This is not a movie set in the future. This is now. Vending machines have been fitted with biometric ID reader that scans your fingertips. Hitachi's new authentication systems identify individuals based on the unique blood flow patterns in their fingers. With the introduction of the system, office workers can buy drinks and other goods from vending machines or at stores in the company building, simply by placing their fingers over a scanner!
