FBI officials have scanned the irises of nearly 460,000 people in a pilot program that may soon replace fingerprints. While iris-scanning technology has been around for more than 25 years, it's just now getting to where it's fast, easy and relatively bug-free. ...This is not about IDing criminals. (1) Irises don't leave oil on doorknobs and coffeecups. Fingerprints do. If you didn't get a nice well-focused picture of the criminal's face, irises won't help. (2) It doesn't work on introverts like me, who never raise their eyes to camera height. (3) Professional criminals do not have ears that fall off when touched, which means they are physically capable of wearing sunglasses, even perhaps MIRRORED sunglasses. Real purpose? Most likely a simple binary decision. If we can scan your eyes, you're OK. If we can't, it means you're an introvert (= terrorist) or a Luddite (= terrorist).
