1. A method of payment of bills, the method including the steps of:

  • providing a printed bill, the bill having printed thereon;

    human-readable information indicative of at least one parameter relating to a requested payment; and

    a position-coding pattern comprising a plurality of target elements and coded data indicative of an identity of the bill and of a plurality of locations on the bill, at least some of the position-coding pattern being coincident with the information;

    positioning an optically imaging pen operatively relative to the human-readable information, said pen having a nib;

    optically imaging target elements and coded data;

    calculating a position of the nib; and

    generating digital ink in the pen, said digital ink being a sequence of captured pen strokes, each stroke containing data indicative of the identity of the bill and the position of the nib relative to the bill;

    sending the digital ink to a computer system such that the computer system can identify the at least one parameter relating to the requested payment and initiate payment of the bill,wherein the position of the nib is calculated using the coded data, a perspective transform and a known spatial relationship between an optical axis of the pen and the nib, and wherein the perspective transform is determined using the imaged target elements which are perspective-distorted due to a tilt of the pen.
