According to a Wired article, the technology is meant to allow soldiers in the field to record facial features, iris scans and other details of people up close or from a distance using commercially available smartphones.
The current technology the military uses requires the device to be very close to the subject which the new tool is supposed to fix.
The biometry device will come as an accessory that will wrap around an existing phone to add the new capabilities.
According to AOptix, a smartphone using its sensing device would weigh under a pound and only need one hand to operate.
Under the contract, CACI will help with DoD deployment criteria for the biometric accessory.
