In a system for verifying a person's handwritten signature on a travelers check or the like by comparing the signature with a signature previously written by the person whose name is signed, both signatures are written on signature fields on the face of the check. Each field incorporates a similar arrangement of lines of pressure sensitive material that produces visible marks on the back of the check at points at which the lines of the signatures cross lines of the pressure sensitive material. When the patterns of marks thus produced are compared, dissimilarities between the patterns indicates that the two signatures were not made by the same person.
