Electronically transmitted document delivery through interaction with printed document

A system for delivering an electronic document, the system comprising:

• a printer for printing on a substrate user information visible to a user and coded tags invisible to the user, the user information including information indicative of a send instruction, each coded tag encoding an identity unique to the substrate and a location of the coded tag on the substrate;
• a sensing device for sensing the coded tags on the substrate when the sensing device is moved relative to the substrate by the user interacting with the user information;
• and
• a computer system for electronically capturing a message composed with the sensing device by the user via movement of the sensing device relative to a predetermined area on the substrate, the computer system using the identity of the substrate and a sequence of respective locations of coded tags sensed by the sensing device for determining the predetermined area on the substrate and to electronically capture the message
• wherein, upon the sensing device sensing at least one coded tag coincident with the send instruction, the computer system transmits the message to a recipient address.
