Pro-detector / Currency detector

According to the data from World Health Organization, there are about 37 million visually impaired people in the world. Because of visual impairment, the impaired people can’t go to work independently. But lots of visually impaired people still need to make money their own due to economic reason. However, they can’t recognize the face value and authenticity of the banknotes and gather statistics for revenue. Therefore, the main concept of Pro-detector is to help visually impaired people recognize the face value and authenticity of the banknotes. To go a step further strengthening their ability of economic self-sufficiency.
