  • providing a bill containing;

    (A) information relating to a requested payment; and

    (B) coded data printed as a collection of tags, each tag identifying;

    (i) an identity of the bill, and (ii) a location of the tag on the bill;

    interacting with a zone of the bill using an optically imaging pen, said pen comprising an image sensor, a processor and a nib;

    capturing, using the image sensor, an image of a tag within the zone;

    computing, in the processor, the position of the nib on the bill using;

    (i) the tag location identified in the imaged tag, (ii) an observed perspective distortion on the imaged tag, and (iii) a known spatial relationship between the pen'"'"'s physical axis containing the nib and the pen'"'"'s optical axis containing the image sensor, said axes being different from each other;

    transmitting indicating data from the pen to a computer system, said indicating data being indicative of the identity of the bill and a position of the nib relative to the bill; and

    identifying, in the computer system, at least one parameter relating to a requested payment associated with said zone, using the indicating data and a map of the bill maintained in the computer system.
