Facial and fingerprint recognition technologies are expected to see accelerated growth over the next five years. The market value of facial recognition technologies is expected to nearly double from $230 million in 2015 to $450 million in 2019. Fingerprint sensors will continue to increase each year to peak at 1.6 billion in 2020. Iris recognition on smartphones is also seeing an uptick in adoption, though it still represents a tiny sliver of the market. Facial recognition technology is primarily used in security and monitoring systems, its use is gradually expanding to other areas.”]
