Abstract

A fraud prevention system for magnetic ink character recognition includes providing a colored, highly reflective media and magnetic media over a non-magnetic toned image which can be an on-line or off-line component of an imaging apparatus. Colored media and magnetic ink are applied to selected characters from a thin film that includes a layer of colored media and a layer of magnetic media by utilizing a heater member to promote release of the colored and magnetic media to the previously toned characters.
