Eye Scanner security bot thing

This scanner thing will be the very near future securtiy desk. Have you ever seen those mocies where a scanner wll scan somones eye to idenitfy them? Well they already have the idea made up and it kinda sounds like they are already have them being manufactured and selling thme but i am not sure. This identifaction device could speed upthe time it takes for people to get where need to be going. Instead of going to the securtiy desk and the security officer having to identifiy you (which could take a few minutes) you could just get your eye scanned and be in. Also this device would take away the need for a security officer. You dont have to pay a machine. What kind of technologgy would you like to see in the future?   Sorry for no picturre the article didnt have picuters.
