Biometrics, and fingerprint scanners in particular, are effective in helping soldiers tell who’s an ally and who’s an enemy. The drawback to biometric scanners, however, is that the person in question has to come in physical contact with the soldier scanning his/her prints; thus putting the person doing the scanning in danger every time they want to read a potential criminal’s prints.
Well not anymore. Thanks to advancements in camera and fingerprint scanning technology, soldiers can now get their scans from a distance of up to two meters, meaning they can be safely behind a blast-proof window or remain in a vehicle as they scan the questionable person’s fingerprints—all in less than five seconds.
As of now, the fingerprint scanning system (known as AIRPrint), is only in the development stage, where it can manually scan one set of prints at a time and only from a fixed distance. However, the final system, which is set to be released before the end of the year, should be able to scan up to five prints at a time and even track hands in real-time as the person moves around.
