If security is an issue for you, or you've just been intrigued by the high levels of security in movies and on TV, you should check out Panasonic's new iris scanner. The BM-ET200 Eye Scanner will give you an accurate identification in mere seconds. Panasonic must have thought $2,417 was a bit steep, so they threw in a handy USB access feature for good measure.
Implications - The BM-ET200 Eye Scanner can also talk and will ask you to "move closer" if you are too far away. If you speak a different language, no need to fear because the machine can speak five different ones! Having an iris scanner is great if you have extremely valuable goods in your home.
