The AIRprint long-range fingerprint scanning device from IDair is able to rapidly scan from distances of up to 20 feet. The device provides faster identification and improved security in any location including hospitals and stores. The AIRprint works by using flashes of polarized light and two 1.3 megapixel cameras to create complete images of fingerprints. One camera detects for horizontally polarized light while the other detects vertically polarized light. Together they work to form detailed fingerprints of individuals within the scan range. Even when individuals are in motion, the AIRprint is able to scan fingerprints within a tenth of a second.
