A METHOD FOR COMPARING THE FRICTTION-RIDGE PATTERN OF A PORTION OF SKIN WITH A REFERENCE FRICTION-RIDGE PATTERN COMPRISING: PRODUCING AN OPTICAL IMAGE OF THE FRICTION-RIDGE PATTERN DIRECTLY FROM SKIN CONTAINING THE FRICTION-RIDGE PATTERN; PROJECTING THE OPTICAL IMAGE ON A SCREEN; SERIALLY PERFORMING A PLURALITY OF SCANNING OPERATIONS OF DIFFERENT TYPES ON THE OPTICAL IMAGE THEREBY PRODUCING A FIRST PLURALITY OF ELECTRICAL SIGNALS DIRECTLY REPRESENTATIVE OF THE OPTICAL IMAGE; GENERATING A SECOND PLURALITY OF ELECTRICAL SIGNALS DIRECTLY REPRESENTATIVE OF THE REFERENCE FRICTION-RIDGE PATTERN AND EACH CORRESPONDING TO THE DIFFERENT TYPES OF SCANNING OPERATIONS; PERFORMING A SERIES OF COMPARISONS IN EACH OF WHICH A RESPECTIVE ONE A SERIES OF COMPARISONS IN EACH OF WHICH A RESPECTIVE ONE OF THE FIRST PLURALITY OF ELECTRICAL SIGNALS IS COMPARED WITH A RESPECTIVELY CORRESPONDING ONE OF THE SECOND PLURALITY OF ELECTRICAL SIGNALS; PRODUCING A PLURALITY OF ELECTRICAL SIGNALS EACH OF WHICH IS INDICATIVE OF THE RESULTS OF A RESPECTIVE ONE OF SAID COMPARISONS AND WHICH IS AFFIRMATIVE WHEN SAID RESULTS ARE INDICATIVE OF IDENTITY BETWEEN THE FRICTION-RIDGE PATTERN AND REFERENCE FRICTION-RIDGE PATTERN; AND. UPON AT LEAST TWO O THE LAST-NAMED SIGNALS BEING AFFIRMATIVE, PRODUCING A SIGNAL INDICATIVE OF IDENTITY BETWEEN THE FRICTION-RIDGE PATTERN AND REFERENCE FRICTIONRIDGE PATTERN.
