  • providing the printed form, said form containing human-readable information and machine-readable coded data, the coded data being indicative of;

    an identity of the form and a plurality of locations on the form;

    operatively positioning a sensing device relative to the form;

    sensing at least some of the coded data;

    generating indicating data using the sensed coded data, said indicating data being indicative of the identity of the form and the position of the sensing device relative to the form; and

    sending the indicating data to a computer system, thereby enabling the computer system to identify the data for entry,wherein said coded data comprises an ink composition containing an IR-absorbing dye and a singlet oxygen quencher.
