Retinal recognition of biometric technology.

The retina is the layer of blood cells at the bottom of the eye.
retinal scanning is the use of low-density infrared light to capture the unique characteristics of the retina, the only pattern of blood cells is captured.
Retina is a very small nerve located at the back of the eye (1/50 inch), it is the human eye to feel light and pass information through the optic nerve to the brain's important organs, it is similar to the function of film, the blood vessels used for biometric recognition around the nerve retina, that is, the farthest of the retina four layers of cells.
, the advantages of retinal technology 1, the retina is an extremely fixed biological characteristics, because it is "hidden", so it is impossible to wear, aging or for disease effects.
2, the user does not need to have direct contact with the device.
3, is one of the most difficult to deceive the system because the retina is not visible, so it will not be forged.
, the disadvantages of retinal technology 1, retinal technology has not been tested.
2, it is clear that retinal technology may cause health damage to users, which requires further research.
3, retinal technology is not attractive to consumers.
4, it is difficult to further reduce its costs.
