People hold a common idea that red ink cannot be used on a check. Purportedly, the check scanners cannot read red ink and the check will not be processed. However, this myth holds no real weight. Even if this were the case, a human would later review the check and still validate it. As such, you can use red ink on a check with ease.
Take out your check book. Detach a single check.
Use your red ink pen to fill out the pertinent information. Fill in the amount of the check, the recipient’s name and an optional memo.
Mail or give your check to the recipient. He can cash your red ink check at his bank.
