One way to focus on preventing check fraud is to include a separate section on the subject in teller manuals. That section can emphasize typical check fraud schemes and warning signs. A check that does not have a MICR line at the bottom. A routing code in the MICR line that does not match the address of the drawee financial institution. MICR ink that looks shiny or that feels raised.
Magnetic ink is dull and legitimate printing produces characters that are flat on the paper.
A check on which the name and address of the drawee financial institution is typed rather than printed, or that includes spelling errors. A check that does not have a printed drawer name and address. A personal check that has no perforated edge. A check on which information shows indications of having been altered, eradicated, or erased. A signature that is irregular-looking or shaky, or shows gaps in odd spots.
