Chu also noted that though the iris recognition technology has been in existence for a long time, there are several obstacles preventing its widespread adoption: “The main problem is the cost of the camera system that supports iris recognition rather than the cost of the IR LED component. Currently, most cameras filter out infrared light to prevent signal noises from affecting image quality. Therefore, an iris scanner will actually need two cameras with one specifically for detecting infrared light, making the cost of the feature very high. Additionally, there are still many challenges to the development of mobile payment, including regulations and infrastructures. These issues must first be dealt with. If major e-commerce companies or consumer electronics brands can help in accelerating the growth of mobile payment in various types of transactions, then iris recognition technology will have a chance to develop rapidly as well.”
