32. A computer program product stored on a computer-readable storage medium for processing a paper document, the computer program product comprising: code for receiving an identification code associated with an identification tag; code for determining, from a first database storing information associated with a plurality of feature descriptors, electronic information to be associated with the identification code, the code for determining comprising: code for obtaining an electronic representation of contents printed on a first paper document; code for selecting a portion of the obtained electronic representation; code for locating one or more zones on the selected portion; code for determining a first feature descriptor based upon at least one zone of the one or more zones on the selected portion, the first feature descriptor being distinct from the identification code; code for determining a matching feature descriptor from the first database that matches the first feature descriptor; and code for determining, from the first database, electronic document information associated with the matching feature descriptor; and code for storing the identification code and the electronic document information associated with the matching feature descriptor in memory, whereby the electronic document information associated with the matching feature descriptor is associated with the identification code and is determinable using the identification code.
