Description

technical field [0001] The invention relates to the field of POS machines, and specifically designs a POS machine for iris recognition. Background technique [0002] The human eye structure is composed of sclera, iris, pupil lens, retina and other parts. The iris is the ring-shaped part between the black pupil and the white sclera, which contains many detailed features of interlaced spots, filaments, crowns, stripes, crypts, etc. And once the iris forms during fetal development, it remains constant throughout life. These features determine the uniqueness of iris features, and also determine the uniqueness of identification. Therefore, the iris feature of the eye can be used as the identification object of each person to complete the verification of various functions. [0003] Most of the current POS machines use passwords to confirm their identity. However, once the passwords and bank cards are stolen, the thief can easily use the POS machines for consumption.
