A fingerprint comparator includes a projection system including a source of light and a carrier for mounting samples of prints to be compared with an optical system for projecting the images of the samples side-by-side on a screen with one image reverted and the screen divided with the images being movable toward and from the dividing line appearing to merge and emerge from the central dividing line for a precise adjacent comparison at the dividing line. An alternate embodiment uses a split video screen and provides for remote transmission of either the record or sample print.
