The CBC is reporting that the Halifax port authority will soon be scanning the veins in the hands of their employees. The technology known as vascular biometrics, created by Identica Canada Corp. of Toronto, is apparently much safer than scanning eyes. Vascular biometrics maps the veins in the employees hand and stores data on an id card, when an employee enters the port they will be required to swipe their card and place their hand on a scanner, the system uses pattern-recognition to determine if the identity matches. "So, you are guaranteed the person carrying the card is the person it was issued to." unless the terrorist is carrying a lobbed off hand... or perhaps I've been watching too many movies!
