I am getting phone calls, text messages, and emails from friends asking me what’s the next hottest trend emerging from International CES. I am not exactly a soothsayer, but if you want to jump ahead of the recent buzz words like 4K TV, wearable technology, and drones, you can’t ignore iris scanning. Yes, your eye balls. Fingerprint scanning is still in its infancy, but using an iris scanner is coming of age.

Pete Pachal of Mashable was spreading the word about a company called EyeLock on the first day of the show. EyeLock is a security company focusing on iris technology. They created something called the myris, a device the size of your computer mouse that scans your eye. According to Pete’s Mashable write-up, the entire process is pretty simple. “You plug the myris into the USB port on your computer. Pick it up, flip it over, look at it, and the sensor will immediately scan your eye to verify your identity.” That is pretty awesome.

EyeLock claims your iris is the ultimate master password. Fingerprinting is not as reliable. DNA is the “last word” in authentication. But Iris scanning is next in line.

The myris is compatible with Windows PCs, Macs, and even Chromebooks. It supports up to five different users.
