46. A system for processing a paper document, the system comprising: means for receiving an identification code associated with an identification tag; means 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 means for determining comprising: means for obtaining an electronic representation of contents printed on a first paper document; means for selecting a portion of the obtained electronic representation; means for locating one or more zones on the selected portion; means 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; means for determining a matching feature descriptor from the first database that matches the first feature descriptor; and means for determining, from the first database, electronic document information associated with the matching feature descriptor; and means for storing the identification code and the electronic document information associated with the matching feature descriptor in a 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.
