Do you know any trellis site discussions contained by details something like what is the eye scan?
Answer:
An iris scan is similar to taking a photograph and can be perform from about 10 cm to a few meters away. There is no entail for the person to be identified to touch any equipment that have recently be touched by a stranger, thereby eliminating an objection that have been raise in some cultures against finger-print scanners, where on earth a finger has to touch a surface, or retinal scan, where the eye can be brought severely close to a lens (like looking into a microscope lens).
Iris scanning is a relatively foreign technology and is incompatible with the severely substantial investment that the law enforcement and immigration authorities of some countries hold already made into finger-print recognition.
