Title: Method of enabling entry of data into a computer system via a printed form

Abstract: A method of enabling entry of data into a computer system via a printed form is provided. The method comprises the steps of: (i) providing the printed form, the form containing human-readable information and machine-readable coded data, the coded data being indicative of an identity of the form and of a plurality of locations on the form; (ii) operatively positioning a sensing device relative to the form; (iii) sensing at least some of the coded data; (iv) generating indicating data using the sensed coded data, the indicating data being indicative of the identity of the form and the position of the sensing device relative to the form; and (v) sending the indicating data to a computer system, thereby enabling the computer system to identify the data for entry. The coded data comprises an ink composition containing an IR-absorbing dye and a singlet oxygen quencher.
