No. Iris? Perhaps.

Does Samsung Have a Retina Scanning Smartphone Coming? (TechnoBuffalo)

The iris (left), which gives people "eye color," controls how much light enters the eyeball. The retina (right) is the structure laying along the inside, back surface of the eyeball that translates light into nervous impulses for the optic nerve to send to the brain.

In a camera analogy, the iris would be, well, the iris, since cameras have them, too. The retina would be the film, or in an even better digital analogy, the charge-coupled device (CCD) that translates light into ones and zeros for computer chips.

Mobile iris technology is much more straightforward than mobile retina technology and is far more likely to be coming soon to a smartphone near you.
