A check protector comprises a print head operating under microprocessor control to print on a medium two separate patterns of characters, each indicating the same amount, preselected by means of a keyboard, and for printing immediately before one of the patterns an intelligible message indicating that the predetermined amount is a maximum amount, thereby to produce a secure financial instrument which is difficult to alter or forge for the purpose of increasing the amount.

Secure financial instrument and method and apparatus for printing same

The check protector comprises a print head with a plurality of parallel pins in a vertical line perpendicular to the direction of movement of the head. The ribbon in the check protector has at least two bands, one band being associated with half the print wires and the other band being associated with the rest of the print wires. In this manner, the amount on a check is imprinted in alternating bands of color to make alteration difficult.
