Forgive me for possibly sounding like an idiot..
But, how would purchasing MICR ink help protect you from fraud?
Oh yeah, because they won't sell MICR ink to those intending to commit fraud.
I still can't figure out how half of those anti-fraud measures work... Okay, so if I copy a document on a copier, it'll say "VOID VOID VOID" all over it. What's to prevent me from duplicating the document on the same type of paper with VOID VOID VOID hidden in the background? Other than that background, the rest is very easy to reproduce. Oh, and how does the person cashing the check know that the original VOID VOID VOID background was even there?
For instance... how many of you know what MY checks are printed on? If you had my account number, nothing would stop you from printing fake checks on ANY check background... it doesn't have to have my particular background on it.... And, if MY checks have a line that says "verify that this check has a watermark on the back" or something like that, then here's a hint... omit that phrase when copying it onto another blank check.
