Abstract
A multiple ply document for receiving recording information includes a top ply having a machine readable code printed thereon, one or more intermediate plies and a bottom ply secured together by means of a line of adhesive along one edge thereof. The top and intermediate plies are secured to respective overlying and underlying plies by means of staggered lines of adhesive to secure the piles at another area of the document. The top and intermediate plies also each include a line of weakening slightly below the respective line of adhesive to permit removal of a portion of the first ply and of the middle plies and leaving an upper portion of the top and intermediate plies on the document.
