ELLSWORTH AIR FORCE BASE, S.D. -- Gary Parker, 28th Bomb Wing Information Protection Office personnel security program manager, demonstrates how their new digital fingerprinting system allows security professionals to electronically capture images, Dec. 10. The system automatically scans for smudges or other problems, and will alert the user to rescan the fingerprint if there are errors. (U.S. Air Force photo/Staff Sgt. Marc I. Lane)
