Myris: No more user names. No more passwords.

Isn't that about the security that you can get from a 7-character password (alpha numeric, caps allowed, no symbols)? They can improve that if they use a KDF like scrypt, but it's unclear whether they do that.

Instead, most iris scanners use a near infrared camera and light instead. Near-infrared LEDs are cheap and and since you can't see the light it doesn't bother you. CMOS cameras can see near-infrared pretty well without any special processing. Typical CMOS cameras usually have a near infrared filter because without it images tend to look weird with the extra near-infrared light. So a standard sort of webcam or the camera in your phone won't work.
