Common questions
What was HIIDE used for operationally in the field?+
Soldiers used it to enrol local individuals on the spot and immediately query the captured iris and fingerprint data against the Department of Defense's biometric database, supporting identity verification and watchlist checks in areas without fixed enrolment infrastructure.
Why combine iris and fingerprint capture in one handheld device rather than using one modality?+
Iris capture works quickly and at a distance with minimal contact, while fingerprints support cross-matching against existing law-enforcement and immigration fingerprint records, so pairing the two modalities in one unit widened the range of databases the field capture could be checked against.
