Abstract: A check and magnetic strip arrangement is set forth wherein a negotiable instrument comprising a check is arranged with a first magnetic strip positioned adjacent a right edge on a rear face of the check forwardly of a signature line on a forward face of the check with a second magnetic strip of equal information positioned underlying the signature line adjacent the bottom edge of the check on a rear face of the check orthogonally relative to the first magnetic strip. The second magnetic strip is positioned to extend from the right edge of the check to an orientation somewhat medially of the check to provide adequate spacing for endorsement of the check on the rear face of the check along the left edge thereof.
