Claim 10:
11. A method for making a security-code selection and recall device, the method comprising:
providing a viewfinder wheel with at least one viewfinder window;
rotatably coupling together two or more code wheels with the viewfinder wheel about a common axis;
placing a plurality of characters spaced about a circumferential outer side of each of the viewfinder wheel and the two or more code wheels; and
placing a plurality of code symbols located in two or more regions of a surface of each of the code wheels, each of the regions is spaced out a different distance from the common axis; and
forming a plurality of internal windows in at least one of the code wheels adjacent the viewfinder wheel, wherein alignment of one of the characters of each of the viewfinder wheel and the two or more code wheels at a key sequence location reveals through the viewfinder window and one or more of the internal windows a code sequence comprising a subset of the code symbols.
