This scanner grants you access to something but not the all awaited for door.
Myris is a palm-sized device that scans the eye. This will allow you to replace your passwords with the most secure password of all, the iris. There is a 1 in 2 trillion chance that someone will be able to replicate your password. It will not fall for photos or videos of the iris meaning it truly is one of the most secure forms of a password.
It is not the eye scanning door that we see in the movies but the company, EyeLock, is not far off. They have several items listed on their site that pertain to the purpose of door security but they don't seem to be putting them on the market at the moment. This proves that it is possible and it will be done but most likely for a premium price.
Myris can be found at places like Staples and BestBuy for a price of $279.99. This means that their later products are likely going to be more expensive than this price tag because they seem to be much more complex than Myris. Only the future will tell us when we can be expecting such a great step in technology.
