Security document.

摘要

A security document (10) is provided having a designated area of weakness (16) which is capable of subsequently receiving an image thereon of a predetermined amount to be paid. The area of weakness preferably comprises an area having a plurality of lines of weakening (18) formed therein. Any attempt to remove or alter the image will further weaken the area of weakness causing premature failure, thereby providing an indication of attempted alteration to the document.
