Guardian® USB

Compact, rapid capture, dual use criminal and
applicant livescan and fingerprint enrollment system.


L SCAN Guardian®

Cross Match Technologies’ original Guardian was the first compact, mobile, ten-print livescan solution to meet the U.S. government’s stringent biometric standards. Designed for rapid, forensic-quality fingerprint capture, all Guardian versions are fully compliant FBI Appendix F certified scanners suitable for both criminal and applicant biometric identity management.

Unique features, such as our patented Auto CaptureTM capability and Perfect RollTM technology, allow foolproof fingerprint acquisition – positioning Guardian as the ideal choice for high-volume fingerprint enrollment and/or verification applications where accurate image capture and throughput times are critical success factors.

Chosen for the Department of Homeland Security’s U.S. VISIT program, Department of State’s Visa program, and numerous other U.S. and foreign government biometric deployments, the Guardian’s durability and reliability is field proven.

The Guardian is your logical choice for commercial, civil, and defense-related applications such as border control, national ID, pension and benefits administration, voter registration, and applicant background check programs.
