EyeLock’s Myris is computer mouse-size device that scans your eye. You plug it into the USB port on your computer, tablet or some other device. You look into it, and the sensor will scan your eye to verify your identity.
While a fingerprint has an error rate one in 10,000, according to EyeLock, iris scans are said to be something like one in 1.5 million.
Samsung’s Galaxy S5 smartphone, due in April, may use eye scanner technology to unlock phones. Samsung, which sells one of every three smartphones globally, wants to fend off Apple in the high-end market, while luring budget customers with handsets for $100.
