Really a bad question to ask but...can the numbers at the bottom of a check be demagnetized by rubbing it on a tv?

I've never heard of this. But if the MICR line were to be demagnetized, the proofing machine would reject it and it would be manually processed.

I don't think it so much a matter of it becoming demagnetized ... but it might rub some of the MICR off.
That would also prevent the proofing machine/scanner from reading it.

Thanks for the info.
