ABSTRACT COMPACT FINGERPRINTING SYSTEM A compact fingerprinting system includes an applicator comprising a sealed packet (13) containing a porous pad (12) impregnated with a solution of water- soluble, color-forming, marking compound, such as iron chloride having a controlled, optimum water content. A print of a body part, such as a finger, is formed by opening the packet (60) and wiping the distal por- tion of a finger (76) on the pad (62), such as a folded towelette to form a non-visible, latent image pattern. The pattern is transferred to a card (40) which can contain an area (44) impregnated with developer for the marking compound. The developer reacts with the pattern to form a dark, distinct, permanent image (84). The card (40) and packet (13) can be enclosed in an envelope (64) to form a low profile, lightweight, mailable, self-administered fingerprinting system.
