| 1. A method of enabling payment of a bill, said method comprising the steps of:
providing a bill containing information relating to a requested payment, the bill including a plurality of tags, each tag
containing coded data indicative of an identity of the bill and of a location of that tag on the bill;
placing an optically imaging pen having a nib in an operative position relative to the bill;
imaging a tag;
computing a position of the nib from an observed perspective distortion on the imaged tag and a known spatial relationship
between the nib and an optical axis of the pen, said axes being different from each other;
generating indicating data in the pen using the coded data contained in the imaged tag, said indicating data regarding the
identity of the bill and the position of a nib of the pen relative to the bill; and
transmitting the indicating data to a computer system such that the computer system can identify, from the indicating data,
at least one parameter relating to the requested payment and enable payment of the bill.
