Some new technology might help with that, plus, with the added benefit of additional security. The new 3D DeskCam from Bioscrypt will scan your face to use as your password, token, or smart card.

The camera uses about 40,000 identification points, looking primarily at a person's forehead, eye sockets and nose bridge, said Ryan Zlockie, director of product management at Bioscrypt. The facial-recognition system has passed tests with identical twins and professional face molds, Zlockie said. A person registered with facial hair who subsequently shaves doesn't have to be reregistered, but somebody who undergoes plastic surgery does, he said.

It's expected to be released in the second half of the year or early next year to consumers.
